Hi I have a 55 plate 2.0 tdi superb I had the warning light come on for the oil pressure so I turned the engine off and had it towed to a local garage. It was the oil pump (I know common fault but I love the car ) had it replaced but now there is vibration coming from the engine and entering the cabin. I can only describe it as a mobile phone type of vibration obviously on a lager scale. its worse the more the revs I give it and its the same when not in gear so not g/box etc . can a pump that's been put on wrong cause this if its possible to be put on wrong, as I am at a loss. All help greatly appreciated thanks in advance

sounds like something was starved of oil and due to heat and friction is now scored did they strip engine to check as the top of the engine would have had a lack of oil as the pump failed

and the norm would be to strip and inspect top and bottom end

Turbo failure?

Crank main bearing failure - unless they removed the balancer module and re-timed it incorrectly. The phase relation of the balance shafts relative to the crank is critical.

If there is main bearing failure, the engine will rumble and may show low oil pressure. If the balance shafts are mis-timed, it will vibrate - badly. Who did the work?

can i ask what milage this happened ?

How long did you run for without pressure, and what speed were you doing when the light flashed on?

yeah 57000

hi i was going about 40 in traffic and when i heard the beeps to the time i had read the warning registered in my slow brain and pulled up safely it was about 3-400 yards then got towed in

hi i will be going back down again today armed with a little more knowledge thanks guys will let you know what happens hope you got the message roto thanks

not sure what they stripped but didn't run for that long genuinely thought all would be good due to run time and residual oil :(

One simple thing that comes to mind, but only if it's a noise vibe rather than a shake you in the seat one, the snorkel to the airbox is a lousy fit once it's been detatched, this gives a throaty vibe off, way to tell is to simply rock it about, if it doesn't seem tight it will be leaking induction noise like having no air filter etc, others again in a similar vein are the rubber parts, the big one between the engine and air filter, below the turbo splits also, and also make sure all the air filter clips are there, and that the box is sitting in the bungs in the chassis, if it isn't the air filter cover looks higher and not in line with the engine cover.

been down and booked in they had a quick look and think that as they lifted the engine off mountings to carry out some of the work it is not seated correctly thus vibration. there was no pick up wear etc when the engine was checked so that's good news. we will wait and see next week will let you all know hope its that simple thanks for all your replies

Find out if they took the balancer module off to renew the oil pump and its drive. If they did, it's very easy to mistime it as the markings are not clear and there is no mark at all on the crankshaft gear. (You have to lock the engine at TDC.)

I've seen one of these engines in bits but not actually worked on one. It should be possible to change the oil pump drive in situ, but this may not be accessible with the engine in the car - the one I saw was on a test stand - and knackered.

If the module has been off, there's a very good chance it has been mistimed - the balancer shafts then become unbalancer shafts.

Hi there cavessuperb....sorry to hear of your woes with your superb...one member already asked you of your cars mileage which answered one of my impending questions....the other if you dont mind me asking, is what is your engine code? the reason i'm asking is i'm trying to find out if the 2.0 ltr diesel engine is the same as mine. Keep us posted of any further developments on your engines well being.....kind regards ...andy

hi yeah they seem pretty sure it is the mountings so its in the end of next week. but if it doesn't solve it then i will be printing a few of these out and making like i know what I'm talking about lol

hi yeah sure think this is what you want V V 103 KW BSS and 7GG think the 7GG refers to the fact its got the dreaded DPF on it. if not what you want let me know

Thanks for that info cavessuperb.....doh thats the same engine as i have !! Although your engine has done around 19000 miles more than we have done in our car........that equates another 2yrs driving compared to the mileage we do.

But still not very nice having to hear of another 2.0ltr superb with oil pump failure. Like you and rotodiesel say...there is a common fault with these engines....what id like to know is how many of these particular engines have actually had oil pump failure? And given the mileages that the dreaded pumps pack up...is there not any comeback on the parent company volkswagon?

I know they give a 3yr warranty or 60k miles which ever is the sooner.....but surely the engine is not fit for purpose if its failing at low miles.I know i am out of warranty as we dont do that many miles hence our mileage of 38k...but we do drive the car very gently...ie nothing over 70mph and if we use 6th gear the revs are so low, its as if the engine is barely ticking over. But at the end of the day...one would assume that that their engine in their car would do at least 80-100 k miles before anything remotely goes wrong with it.....after all we bought our superb for the comfort and the ecconomy and with diesel being generally a long lived engine !!

And just to reinforce our point...we poodled along for like 3hrs non stop from where we live to biggin hill for the anual airshow in 5th gear at 60mph and averaged 52mpg and the same going back...and the engine was so quiet and smooth i cant quite believe that my engine is going to have problems, unlike the unfortunate owners on here. We service the car twice a year...but having said that....by the time the mileage is up to 50 -60k...i think it will be time to upgrade it.

i know exactly what your saying i think we are just little fish and once they have your money dealers are not interested as surly they could report back on the amount of issues they have with the oil pumps. its probably just a drop in the ocean the amount of superbs they sell , its not worth the investment to alter the design . but the way you sound on looking after your car even if you had to get the oil pump done its better than the amount you would lose if you traded it in. you would be better off keeping it and running it into the ground 50-60 k is nothing for that engine just give it a blast now and again so you don't have issues with the dpf

Having read your reply cavessuperb i think you have a good point in suggesting i keep my present car...everytime i go out in it wether it be short distance or long distance i actually enjoy driving it...and having owned it from new and struck up a good relationship with the independant garage i use, i might just keep the car for that little bit longer. I dont think it would be wise to actually part exchange the car and end up way out of pocket when i feel the car has potentially a lot of life left in her.

The independant garage owner i use also has a superb....so he knows the model inside out basically...and he is also very reasonable with his labour rates and above all the honesty side of things. He uses genuine parts as and when required and gives good advice free when needed...so keeping the car in tip top condition is what i'm aiming for in order for it to keep on the road for long ownership.

So a new model will be on the horizon one day...but only if i feel the car is going to really be unreliable....touch wood its been perfect mechanically...and what with the body being galvanised the engine will probably die before the body work lol.

Happily we have a member on this forum

Some people say... he sprinkles metal shavings on his wheatbix and he hates all things german. some say he gets his engieneering skills from god and that he would like to have a few stern words with he chief designer of the B5 Passat.

All we know is that he is called ROTODIESEL
