Ok,so ive got a cr 60 plate vrs that was perfect, remapped it at shark about 4 months ago and was fine bar a slight high idle occasionally. Then I had it serviced by skoda about 2 months ago and within 300 miles I noticed a puff of smoke come out the back. I got home and checked my oil and it was about 10/15 mm above the maximum level.I drained out 1 litre of oil to get it back to half way between min/max. After a month and about 500 miles its back up to the max. And now its constantly smoking under acceleration(unless gentle). I went to shark last week and they scanned it and came up with no faults so going back next week so ben can have a look. Asked skoda and explained(bar the map) and they said its gona be a scan to start with at 50quid even though ive told them its been done and there bound to blame the remap if they find it, and I know theyl charge the earth!(344quid for a service!!)I basically asked them to check there work or if they would do a goodwill offer seeing as its just had the service but they werent interested.during the service it had a diesel injector and engine flush if that makes any difference.Does anyone have any hints on what I should do or what it could be? Would prefer to leave it at shark but its and age away from me!

I would think the oil is being contaminated with diesel, will a scan shed light??

Obviously the oil isn't increasing because of more oil, so there's only one other thing it can be - fuel.

This is symptomatic of a failed DPF regeneration. Either the DPF is on its way out or your driving pattern has meant it's not regenerated successfully. Do you do lots of short trips?

Octavia cr vrs smoke,increasing oil level: https://youtu.be/JQKFhJ79elY

I havent changed my driving atall, bit of town and fast roads. Shark scanned it on vcds and showed no faults and dpf has done 7 regens since April and last was done 120km ago at the time and was 25% full. I was wondering if it could be and injector not closing fully and allowing fuel to pass all the time, hence the smoke and draining fuel through when engine switched off making the oil level go up? But looked for absolutely ages on the Internet and never found a case of a dodgy injector on a common rail vrs?

If the fuel is contaminating the oil, the engine will not be properly lubricated. I would be wary of even starting the engine. Hope you find the cause soon.

The high tick over / idle you mention will be a DPF regen.

 

Having a new injector and fuel contaminating the oil is too much of a coincidence. Take it back to the garage that fitted the injector, something is wrong as it is allowing fuel to enter the sump.

 

How long after this service did you notice the high oil level? Chances are the DPF is really suffering if you've been running it like this for some time.

 

Everything is pointing towards a ****-up by the dealer.

 

They shouldn't be using engine flush either, Skoda UK say that this should not be done, they might be interested to find one of their franchised dealers is using engine flush.

Huh, didnt know they shouldn't be using engine flush, they rang me and talked me into it as I wasnt going to bother!!!! Didnt have an injector changed tho,They just used the diesel injector cleaner which I presumed dislodged something in the pipes which ended up in the injector? If this could happen?

Injectors are getting fairly common on CR diesels too. Not as much as the PD ones. Im interested to know what happens with yours because I have the same symtoms as you on my 2009 CR VRS. I fit a DTUK tuning box and every now and again I get a single puff of black smoke after a good trashing followed by a high idle. I force regenned mine 4 days ago and got the dpf level from 42mg down to less than 5mg so shouldnt be trying regen for a while. Iv got no fault codes but will be removing the tuning box to see if the issue resolves. There is nothing they could have done in a service to make your car fault so your wasting your time trying that route lol. Nothing worse than a "since you serviced my car.... customer"

There are plenty of threads on here to suggest otherwise.

 

The fact the same dealer used engine flush is more than enough for me to suspect a genuine mistake could have been made.

 

A "since you've serviced my car" customer isn't half as annoying as a "it ain't nothing we've done, go away" dealer.

Engine flush is more risky on the older PD engines but they are still not recommended for a number of reasons.

 

The best engine flush is the engine oil itself. Regular oil changes are all that is needed.

 

Skoda make a specific reference in their owners manuals that engine or fuel additives should not be used, hence my surprise that this was done by a franchised Skoda dealer.

 

If all of the sludge and debris that is loosened by the flush isn't removed during the oil change then instead of been relatively safe when it was stuck to a surface it is now free to find a new home.

 

One of a few threads...

I know what you mean, but the car hasnt missed a beat in its 52k but less than 300miles after a service it goes wrong.... It mite be just a coincidence but I bet if it wasn't serviced itd b fine. Any hints on what route to go down? Or just wait til shark have a look and go from there?

Ben really knows his stuff, when is it booked in for? I'd be avoiding too much mileage with diluted oil...

Yeh, im using a van for work so itl just do a maybe 30miles till its trip up to shark next Saturday. I hope this ben chaps all as good as people rave about! Never heard a bad thing about him so heres hoping! Im guessing the diesel can only get into the oil through the injectors?

Youve obviously never worked in a garage (or worked on a car) lol.

As said mine has the same fault and has only started since fitting the tuning box. Iv owned the car for a couple of months and fit the tuning box 2 weeks ago. I havnt serviced it.. but if i had it serviced it would have still faulted at the same time as it did.. but if i was looking for someone to blame/ fix my car for me then i could always blame the garage (if i had it serviced) .

The most likely cause of your problem (and mine) is an over fuelling fault caused by the remap/ tuning box in my case. This will also accelerate the wear of injectors/ turbo etc and could cause further damage.

As said I will be removing my tuning box 2moro.

Seems to be a select few on here that jump straight on the "blame the dealer" band wagon without thinking about the fault and whats been done to the car previously.

Skoda has the highest level of customer satisfaction at dealers of any vehicle manufacturer in the UK. Speaks for itself lol

I've done both.

 

This isn't a DIY tuning box, it's a Shark map.

 

The OP asked the so called 'faultless' dealers to check their work immediately after the service and as the fault was discovered. They appear to have told him where to go. Sounds like great service to me.

In all fairness to skoda, I did plan to go in last week where they said theyd have a look over there work for free, but my misses was coming to pick me up and some muppet crashed into her and wrote her car off!!! So I had to detour and pick her up. Then I asked another chap to rearrange who said theyd have to put it on diagnostics and check for 50quid.curse of the skoda!

Its not a DIY tuning box lol

Its a DTUK box retailing at £399

Whether the map is at fault or not it will have increased the wear of the engine components since it was fitted unlike a service which only prolongs the components.

If you really have "worked at a garage" you would know a service will not cause the faults described above unless they overfilled the oil. But the Op has already mentioned he has drained 1litre of oil + it has filled back up indicating a further issue (not relating to the service).

You are right in that a regular service won't cause issues, but only if done correctly.

 

Things get spilt, thinks get knocked, things get dropped, things get removed and not replaced, mistakes are easily made. Suggesting that because the car has only been in for a service there is no chance that the dealer is at fault is a little naive in my experience.

 

Lots of examples on here over the years but this is one of my favourites, honestly clearly isn't always the best policy...

Injectors are the only route for the oil to get into the cylinders, where it then trickles past the piston rings and gets into the sump. That can be through failed DPF regen or through failed injectors - when they die they can dribble when sat overnight, so you end up with a puddle of oil inside the cylinder.

If the injectors are dribbling you'll get a big puff of smoke at startup (there's a puddle of diesel sat in the cylinders remember). Otherwise it's caused by failed DPF regen like i said originally

I would have a look at the measured values of the 4 injectors. A piezo injector with a high positive deviation reading will be indicative of an injector plunger inside the nozzle not seating correctly thus allowing fuel to drip into the fuel.
