Hi
I posted a question yesterday about a load (ish) rattle from the engine area of my A4 Avant 55 plate 2.0 tdi S-Line. (130 K mile Audi Hist) This can't be detected from inside the car. Along with the noise there apears to be a bit of vibration tranfered into the car this can be felt on the gera knob and slightly through the steering wheel.

With thanks to a member of here, it has been suggested to resreach the 'Oil pump drive chain' (unless anyone else has a possible theory)

I have done this and it's frightened the crap out of me with the potential costs involved.

Trying to look at the possitives, I have looked at Oil chain kits pump kits (around £250 retail) these include genuine Audi tensioner, sprocket and non Audi chain as these are available fro Audi.
These kits are also available with a crankshaft sprocket for a whopping £200 extra and is advised to fit or at least have your checked.

Has anyone fitted one of these kits ? and if so do they do the job ! My car is still running spot on with no oil warning light issues ?

Time and cost wise has anyone an idea of whats involved in fitting the kit, I assume its a ramp and remove the sump to gain access.

Lastly as mine is running fine and according to the prvious owner has been making this sound for a while (at the last service the garage said just ignor it ! obviously they did not know what it was) how long can they go on for ! can I ignor it for a while or is it simply a ticking bomb !

This is my third Audi A4 Avant (all blue !) and I am very concerned over the potential costs involved as I have just bought the car and over stretched my self to get it. How can a car company such as Audi get away with such a massive **** up.

My privious A4s were 1.9 tdis B5 and I was looking for a late B6 but this one came up, I did not know about these problem with the 2.0 engines as I was not considering a B7. How gutted am I, and of course so must many, many more.

Regards far any help/advice

Ian
