My daily driver Skoda has 110,000 miles up, I purchased the car last year with 99,000 miles and its been fine up until now. Everything appears fine except when I accelerate in 4th or 5th gear from about 2500/3000 rpm the engine vibrates roughly badly, I can see the steering wheel vibrate as well as feel it. Yet the car seems to run fine with 55mpg, 1st time starting, no oil burning, in fact as good as always, apart from the vibration. I am a little concerned it might be start of something worse to come.

Its not my week, what with this and my Austin 7.

These suffer from dual mass fly wheel problems, do you get any vibrations when stationaqry are various revs etc?

Thank you for reply, I have'nt driven the car 'critically' so to speak, just could'nt help noticing the vibration problem. Tomorrow I will drive the car and pay more attention to whats going on and write more on the problem then. Thanks again.

Drove the car this morning and found that the vibration is apparent when the engine is asked to work hard at low rev's, 1500-2500rpm pulling 4th or 5th gear accelerating. Other than this area the car is fine? This is my first TDI car, should I be using higher rev band perhaps? or is it a mechanical fault developing?

Should pull cleanly from almost tickover. No excessive smoke or anything like that? When was it last serviced? My gut tels me its either an injector or perhaps a blocked fuel filter or something, but I'm no expert.

Thanks for comment, no the car is not smoking at all, do'nt know when it was last properly serviced altho stamps in the book say 78,000 miles I do not have supporting paper reciepts. I had the cambelt done at point of purchase + oil change at 98,000.

Hi there, at this milage it may be worth checking engine mountings/steadies, they do wear out. Check the simple things first!!. VAG forums are a good place to visit, hope you get sorted.

Had a problem with an Octavia that sounds similar to what you are describing, that turned out to be the offside engine mount. They are oil filled and when they split the oil escapes which causes the vibration. Trouble is you really need to take the mount off to check it properly, altough its not a difficult job.

I had this problem on an old audi with the same lump - it made no difference if the air flow sensor was disconneted and is probably the pump on its way out. With carefull adjustment of the fueling via a laptop it can be helped. It took a lot of attempts to get my one right though

Get the injectors cleaned!!!


I've had exactly this on a few high mileage vag tdi's, each time just undo the injectors for a look at the nozzles (easy enough) and all will be revealed!! Usually all clogged up with coke visibly. Take to your local diesel man who'll clean them up & hey presto its back to normal.

Some good advise on here, Thanks. I noticed in my handbook that in bold lettering it stated do not use injector cleaners! wonder why? I shall have them checked as suggested.
