2.5tdi severe camshaft wear

**shabazmo** · 15-11-2007,11:09 PM

After 110K miles my Audi has severe camshaft wear. I am told that this is a common problem and symtoms are poor starting as the valves do not open as they should.

I have had the car from new and changed the oil with 506.00 oil after every 11K miles, so was shocked to see so much wear. Has anyone come accross this problem?

Now 4 camshafts will cost about £700 plus labour and other parts, so probably £2000 to do the job. I was quoted £3000 from the audi dealer. I could probably remove the camshafts myself ( I did the cam belt 20K miles ago) and take them to an engine shop to be re-profiled at a cost of £300.

I would like to know if anyone has had this problem and what their solution was.
Many thanks in advance.

yes its quite common and the last one i did had new heads as the camshaft bearing caps had cracked.If you did your own belt then youmshould be able to fit the camshafts without to much hassle as long as you have the aligning tools for the camshafts.

Thanks for the information. Did you use new camshafts or re-profilled ones, and where is the best place to buy a new camshaft. Any other advice or parts I should replace.
Thanks

I would rather have a new engine fitted or get new camshafts. When the wear is really bad, they cannot be ground anymore. What year was your car made as there was a faulty batch of camshafts fitted durring 1998 on many a4/a6 that they were not hardened enough ? Why not sell the car as it is and put the money you will spend towards a new car ? I will be interested ! Regards, Chris-07841206564.

Thanks for the interest, but I have a well speced car, leather recaros, heaterd seats, rear park sensors, wood inlay and in canvas beige, a 2002 model, and have looked after it and over serviced it since new, so I am keen to get a good fix. Uses no oil and was getting over 43mpg, but this seems to have reduced to 40 over the last year, and I think cam wear may be the cause.
I heard that the cam wear problem had been solved in 2001, but my local Audi dealer replaced their 2002 canshafts after 110K miles.

Hi,

Can you please share some more info about the problem with camshaft wear? On which engines does it occur? On how many engines does it occur? Was there any service action or bulletin issued by Audi? Where can I find more information about it?

My father's car has similar problem, so I'm looking for more info.

Many thanks in advance for all the help,

Kind regards,

Hrvoje

Car is a 2002 2.5tdi with engine code AYM. I beleive it was acommon problem with pre 2001 engines. As far as I am aware, no service buletins were issued. What car do you have, mileage and age.regards

Hi,

It's late 1999 2.5tdi, bought new, with 180k km (around 140k miles). It was serviced (with oil changes) every 7500km.
The camshafts were completely worn-out, resulting with engine failure.

Many thanks for all the info.

Kind regards,

Hi

My A6 1.9TDI 2001 has severe cam wear evident at 100k and obvious at 130k. VW/Audi specialist recommends Rockwell testing on cam and followers to see if hard enough. If hard enough he thinks fault then lies with garage who were chucking in non spec oil for 30k miles (big mistake by me not to use Audi dealer or specialist for 70k-100k servicing).

I rang Audi UK to see if there were any recalls. They said if I had not heard from my Audi dealership there was no problem and then cut me off.

This is meant to be a quality engine. Is this really a common problem?
