    So was just pulling off the drive this evening head a noise and then the dash started lighting up, battery light, ESP light etc. Pulled back into the drive and had no power steering which made it almost impossible to steer as it was heavy as hell.

    When opening the bonnet i found the serpentine belt rubbing against the cooling fan and the crank pulley at the bottom of the engine bay!

    I managed to get a hook around the ripped off pulley and fish it out.

    It's difficult to tell on the photo but it's the rubber damper that has failed


    Looks like the it's been on it's way out for some time as you can see the rust has seeped into the rubber



    Looks like I'm going to have a fun weekend stripping the front of the car down replacing the pulley.

    It's an easy enough job depending on the condition of the bolts holding what left of the crank pulley in place. Have to say it's the first time I've had one fail.

    Replace the crank pulley bolts when you change it, they're soft and at least 1 will require a 12 point socket hammered on to it IME

    Known issue on early V6 TDi, seen now several threads/posts whilst haunting forums.

    If you have access to TPI / TSB data B5NUT the crank pulley vibration damper was updated to new part as vulcanisation fails.

    There is also a washer which must be used as per TPI / TSB that early V6 TDi didn't have.

    PM/email I will send you info.

    To be fair it's done almost 200K miles, if I had know it was a common failure I would have replaced it when I had the front-end stripped down. I'll be getting new bolst, you do tend to find that all the bolts, clips and nuts at the front of the engine get destroyed, I don't mind replacing them and it's easier when you come to do the job but even with TPS prices it can add a fair amount to the job

    Gupsterg I take it your talking about the compensation washer part number WHT 000 950 A? Looking at etka my part number pulley 059 105 251 AD was dropped 01/08/2014 I've been able to source a new genuine pulley but the older part number for just over 100 and if that last another 200K mile it will just about see the life of car out. The new version is around 240 so it's a fair saving.

    I'll PM you my email address, I made mistake updating elsawin so need to start from scratch!

    B5, sorry to hear Something I'll have to look at as living half a mile from salt water I've found I'm more susceptible to rust than most.

    Good luck in getting it fixed.

    There was no warning as well, and there is little room between the slam panel & the engine so it's not easy to check the condition. The problem you have when it does go it takes out the water pump, power steering, alternator and aircon so the car is undriveable with the water pump out of action, just glad it failed at home and not miles away from home.

    On certain 4F A6 V6 TDI there is a recall over that.
