Resetting the codes won't help you find out what is wrong!
Some of the VW specific code readers are quite good, but the "gold standard" is hooking it up to VCDS. Hope you get sorted.ok thanks
-
As you have warning lights there will be codes stored. You basically need to get the codes read as that will be the biggest clue. Moisture around the connectors sounds like BS, to be honest... unless they cleaned it with a pressure washer (?!). If you want to try and do it without involving the garage, see if there are any members with VCDS near you (http://www.briskoda.net/forums/topic/224376-vcds-owners-map/).
You might be low on the fluid for the DPF, or you might have a blocked DPF (did your oil exit via the turbo and through the exhaust? Had you previously driven around a lot with the DPF lights on?) or it might not have been put back together right. Codes will help no end in diagnosis.
the DPF light only came on once b4 i had the engine sorted it came on 3 weeks after , i only do short journeys i dont think that helps a diesel engine . the oil sensor light only came on after the engine repair ,i assume like you suspect there is oil in the exhaust as i looked at the turbos the mechanic showed me was totally siezed up i did wonder if thes fault code readers are any good off ebay to reset the codes

Just for fun was wondering who the youngest superb driver is on here? I'm guessing its me at 19, don't often see many people driving them until their mid-20's
im 65 guess im not the youngest

Those short journey's are not going to be kind to a diesel unless you are also making some longer trips as well.
yes i only do short journeys i think thats why the diesel particle light is coming on

Hi all got my superb mk1 back a couple of weeks ago new oil pump .Turbo etc not exactly cheap.luckily there was no engine damage !!!! .now the oil sensor warning light is coming on approx once a week and also the diesel particle filer light is now on all the time local garage said give it a good blast down the motorway to shift the particles in the exhaust to extinguish it ,just wondered why the oil sensor warning light comes on the oil levels ok and no leaks wondered if it was owt worth worrying about the mechanic said it could be a bit of moisture around the connection any ideas ?
-
ok thanks for that .i think Skoda have a nerve charging £1200 for an inherent engine pil pump problem that obviously they knew about ,put me right off skodas wish id never bought one

i wonder is it possible to rplace the faulty 2.0 tdi engine for the 1.9 engine ?
-
My suspicion is that due to the inability of the PD principle to meet Euro V > the engineers were busy developing the CR diesels. A PD cannot inject (useless) fuel into the combustion chamber when the exhaust valve is open to burn off the soot filter, because the injector is not and cannot be pressurised at this point. A CR engine has rail pressure available at all times.
So, with the engineers busy on a very important job (VAG sell a lot of diesel engines), the final tweaks to the PD were left to the apprentice. He messed it up big time. They also compounded the felony on the 16 valve heads by fitting Seimens peizo injectors which caused engine shut-down due to oil ingress. These had to be recalled. Luckily, the Superb kept the old 8 valve head to minimise changes to a run-out model.
I don't think our apprentice "spent hours" designing the 2.0PD oil pump drive. I suspect he was an inexperienced engineer who just clicked on a coupling design which was on his database. I suspect he knew nothing of the effects of torsional oscillation in engines.

hi Roto got 78,000 miles so far out of my superb till the pump went last week is it feasible to think if i replaced the hex drive and cleaned the sump filter i could get another few thousand miles out of it ?

well having a good read on these threads, i'd like to add my 10pence worth...i have one of those so called dreaded 2.0ltr tdi 140 bhp superbs as some members prefer to call them and basically write certain issues that give my car and other owners a worrying time over engine problems and what have you. As you can imagine, it all seems doom and gloom and certain owners getting the wind up over wether they have purchased a bad car from the dealers.
Well in my case i have bought my car from new, and probably being one of the last of the mk1 facelift superbs that were around at the time, and in all honestly having read these threads, my car in certain minds of some people on here, should be suffering from alsorts of problems from dpf issues to oil pump failures and water ingress problems to name a few. Now this car does a lot of very short journeys and is never driven above 30mph in that time, and occasionally we take the car out for a nice long drive and to be honest i dont have any of the issues that are mentioned on here. I pride myself on good old fashioned servicing, and having read the service schedule booklet that came with the car, straight away i had a feeling some points of servicing was way too long, especially on the variable servicing.
I mean i know its nice to drive the car for high mileages before a service becomes due, but thats asking for trouble and coupled with high dealer service charges and consumables, which is why i service my superb every 6-8,000 miles with fresh oil and new filters...ok for some that might sound extreme, but i firmly believe that its the manufacturers schedules...ie long service intervals between oil changes that is actually causing these problems.After all the element in the oil filter for example is perishable over time, and to think of that slowly breaking down with hot oil flowing through it day after day week after week and one begins to wonder why the oil pick up pipe becomes clogged with sediment other than oil and the chain of events starts with oil pump failure due to lack of oil being filtered through the pick up pipe and then spreading through the engine right upto the turbo and then major engine problems and expense !!
When one considers the actual cost of a small oil filter which is under a tenner in some good motor factors, and then the cost of the oil, which can be had for around 30 quid and then the cabin and air filter, the actual basic service consumables are quite cheap compared to leaving it in the engine for say 15-20k miles and then paying around 250 quid minimum for the service, and by then the damage has already begun and wont be noticed till later on when the problems start to arise. I know rotodiesel is very knowledgeable in the work that he does, but everything stems from the oil in the sump...if the gauze on pick up pipe is blocked , even partially, then engine wear will be taking place, and hence the oil pump failures and turbo failures and emission problems and warning lights flashing up on instrument panel alarming drivers. So my message is there is nothing wrong with any superb wether it be the AWX engine or BSS or any other lettered vw based engine used in superbs, just service the cars twice as much and it will pay dividends in the long term mechanically...as the superb really is a nice motor, which is why i bought it.
thats exactly what i did replacing the oil and filter at 4,000 mile intervals but my oil pump still failed

i changed the oil and filter on my 07 superb every 4,000 miles but i still had the oil pump failure top quality oil and genuine skoda filter all to no avail im sorry but i am seriously
fed up with Skoda
-
Just out of curiosity...does anyone know how many 2.0tdi superbs skoda have sold? i would imagine in the hundreds in the uk alone....the reason i asked , is that if skoda know of an impending problem regarding these suspect poor designed oil pumps, then why the ****ens dont they do a recall?
After all their slogan is THE MANUFACTURER OF HAPPY DRIVERS.
Well just on this thread alone there are two owners with problems with countless others driving around unaware of the issues lurking inside their engines.
Surely there must be some kind of leverage one can use to get skoda to hold their hands up and admit yes we have a problem......and get these issues sorted.
i contacted SUK but got nowhere they dont seem to care about customer relations at all there not interested , i have the same superb oil pump problem , the problem to me seems the very small shaft driving a larger shaft which is considerably larger it seems to me fairly obvious the hex key is going to round off , try turning a shaft with an allen key there is hardly any contact its obviously going to fail after a few thousand miles

And yet that's how it was designed :(
I would expect better design from any apprentice. I'm assuming the 'designer' had no practical experience at all. When I was playing around with a stepper motor, it took me less the 5 minutes to realise I couldn't just bolt it to something without a oldham coupler (or something similar).
Off the record, I've been told that the NC machines would 'randomly' miss out the reaming step before the broach was used to create the grooves. The broaching tool was aligned to the unreamed hole. When the step was omitted, no alarm was raised. After looking at loads of balancer units and their replacements, this explanation seems to ring true.
if only id bought an Octavia instead
-
Reassuring to note that there is a definite improvement in quality of the replacement balancer units. Is there a part # for these or a related service Is it possible that this part was also used on later Mk1 Superbs, or is it likely that there was a shed somewhere that VAG kept the shabby units and said to Skoda "Here, have those and stop annoying us". Considering a pre-emptive strike and getting local garage to do for a TB change and BSM replacement before anything unpleasant happens (it is 4 years old and just squeezed off 30K on the clock). Is this similar to the "chainless" upgrade that our friends over the water have been doing on their BHW engines (part 03G 103 295Q I think!).
The latest modification to the oil pump balancer shaft came in ,in 2011 cost around £1,000 plus fitting
-
Lots of confusing information there.
Very briefly, the 2.0 PD differs from the 1.9 in having twin Lanchester balancing shafts which contra-rotate at 2x crank speed. The first engines used a chain drive which was a complete disaster (pictures on your link) and the later engines a gear drive. All 2.0 PD Superbs got the geared drive.
The problem with the Superb's 2.0 PD engine is the drive from the slave balancer shaft to the oil pump, which is a piece of 6 AF hex bar which has inadequate engagement depth with the grooves in the slave shaft. Due to the extreme torsional oscillations in the drive (the same ones which wrecked the earlier chain drive system) the grooves in the balancer slave shaft and the corners of the drive shaft strip and drive to the pump is lost.
Apart from offloading a pile of duff engines into "Skodas", VAG have not done much, as far as I can see to properly fix this - the oil pump drive shaft length increased from 75 to 100 mm according to EKTA, no doubt as a cheap fix by increasing the engagement length. They're never going to fix it properly either, the PD engine is dead.
Avoid all 2.0 PD engines. The 140 in practice produces no more power in the useful rev range than does the 1.9/130
The 1.9 engine has a chain drive to the oil pump - only. It's a nice smooth drive with no torsionals, just what a chain needs. The drive on the 1.9 will last the life of the engine.

Hi Roto i wondered is it possible to replace the faulty 2.0 tdi engine with the good engine with no inherent problems or would that **** everything up ?
-
Agree they obviously knew about this problem , absolutely awful oil pump design ,Does the modified oil pump kit sort the problem out ? 900 quid i got quoted plus fitting ,these people who are vocal about skodas doing 200.000 miles plus obviously havent got this dreaded engine
-
OK thanks for that i didnt really think it was feasible ,basically you need the full replacement modified 2011 oil pump kit then ? or can you just buy the balancer unit and the drive key the garage repairing the car have a new oil pump £178 you dont know really what options to take if you fit this new modified oil pump and there has been some damage done to the engine you'd be throwing your money away as theres no real way of knowing if the engine is damaged i only drove roughly half a mile before turning the engine off so hopefully no damage will have been done !!!
Only certain Chassis numbers were affected in the VAG range so VAG must have known about the problem ,they were very evasive when i spoke to them ,

That is why the standing advice on here is to run if you are offered a 2.0. Of course, there are people driving them, that haven't failed yet, and some are very vocal about it being a great car etc etc... They've generally been lucky - a few might have pre-emptively upgraded to the longer parts - but it is a disaster waiting to happen :(
yes it is a great car, pity about the engines that are affected ,even ford diesels with not a very good reputation you can expect at least a 100,000 miles with no problems
-
I agree with roto's analysis. All the pumps I've seen, are OK except for the rounded off hex coupler. If you turn the rounded off shaft by hand, the pump itself seems fine.
Anyone who hasn't seen one of these couplings and envisages a chunky 1/2" shaft will be disappointed. It is actually 6mm and looks like a 3" piece of Allen key. This would be OK if it ran on its flats where it is driven by the balancer shaft, but no. The hole is not hex shaped. It runs on its points in shallow grooves on the shaft so the contact area is small. The more it wears - the more it vibrates. The more it vibrates - the more it wears.
A former colleague described this as being "a bit like a 6mm allen key in a 7mm bolt-head". He now works for an engineering firm and came up with his own solution.
One of the guys there drilled and threaded the hole in the balancer shaft and made a custom coupler. I assumed that there must be a good reason why VAG hadn't used this arrangement, but the new coupler (and pump) is still good after nearly 120k.
I wondered if it was possible to weld up the allen key to the coupler by a specialist welder ,does that sound feasible ,maybe your guy who came up with his own solution would know if welding was feasible ,i dont fancy spending £1,600 on a skoda updated 2011 oil pump kit , i have sent a letter off to Skoda about this oil pump problem but doubt i'll get anywhere ,to be honest i think the cars affected should have been recalled ,not happy at all
any advice would be appreciated ronnie
-
I think that unless you stopped very soon there can be some other damage from the failure - so it might not stop at the oil pump...
hope not the engine revs died down i went approx half a mile ,the garage man said the engine sounded fine i suppose you wont know until after a few miles
This might sound a bit silly but would it be possible to get a specialist welder to weld the hex drive key to the pump assembly ?
-
It's a bit out of date - the Superb never had the chain driven balancer shafts (eg. BHW engine) which was, predictably a complete disaster.
Rather than fix the job properly (all of their decent engine designers were probably working on the CR units) dear old VAG substituted a gear drive with a central idler for the abysmal chain drive, but left the oil pump coupling as it was. This is the build state of the PD140 Superb. Sheer genius.
This problem has cost a lot of people a great deal of money and inconvenience. Coupled with VAG's other stupidities and dishonesties such as not testing the Teves Mk 60 ABS controller properly, not recalling RHD B5.5s for rain water ingress etc., there is only one conclusion I can draw.
That these people are not honest enough to be worth doing any future business with.

so thats whats wrong with my superb oil pump then ;i contacted Skoda UK about this oil pump problem and they immediately knew the part number i needed ,obviously a known fault they have tried to keep quiet about
-
i contacted Skoda about my oil pump problem its an 07 plate they quoted me around a grand for the replacement part plus of course labour costs on top my Superb has hardly done any miles at all 78,000 they also said the part was updated in 2011 ? so how many engines have been affected by oil pump failure ,i suspect there are a lot more than we know about im not knocking Skodas but this oil pump problem seems to have been kept quiet i maybe wrong
i would ad also that not many Skos da owners visit this site only the savvy ones
skodas

All of the 1.9 and V6 diesels are OK as are all of the petrol engines (although the 1.8T will sludge up if lubrication is not optimal).
I strongly suspect the oil pump drive coupling has been modified on the later 2.0 PD engines as this problem now seems to have "gone quiet". Typically, VAG neither admit to the problem ever existing nor give any info as to the serial numbers of the affected engines - leaving owners of 2.0 PD engines with a high degree of uncertainty - or a big bill.
Should we be doing business with people like this?

i have had the same problem with the superb oil pressure stop engine warning light mine is still in the garage its only done 78.000 miles i tried to contact the chief executive of Skoda but had no luck as yet this problemas far as i know affects all VW,AUDI AND SKODA A4 engines .i wondered why the rep of Skoda said in his first words there would be no goodwill gesture ?did he already know about this oilo pump problem the car has done only 78.000 miles some people can cover this in two years with a nhew Skoda
your car has done a lot less than mine in mileage terms yet it seems you also hAD oil pump failure it seems the oil pump modification was introduced in 2011 so it makes you wonder how many VW AUDI and SODAS are affected there must be hundreds
-
when i called Skoda UK i was quoted a part number replacement oil pump sump etc £957 i realise mechanical things need replacing but i think this oil pump problem has somehow been kept quiet i only came across it on this site ,my skoda has only done 78,000 miles i expected a lot more to be honest being a diesel ,the car has had regular oil changes and servicing .the person i spoke to was basically not interested and told me to take it to a skoda dealer.which would cost at least £2,000 for an engine that has basically done very few miles i am seriously not happy with skoda and am considering calling watchdog i am not at all happy with my Skoda Superb
Some of the VW specific code readers are quite good, but the "gold standard" is hooking it up to VCDS. Hope you get sorted.
