    This issue happened in our Diesel Amarok recently but the TDi T5's are susceptible to it as well.

    THis is the EGR valve assembly which incorporates an exhaust gas cooler

    THis is what happens when water gets in the elctronics of it

    We believe the issue is cused by condensation in the exhaust makeing its way trough the mechnaism and seals into the electronics houseing. As the majority of our trips are too and from work only 6km each way the engine never realy warms up and clears the moisture from the exhaust. So after only about 50,000km and 4 weeks out of waranty a $1700 repair bill :(

    Im going to have a go at cleaning up the corosion and see if I can resurect it and next time it plays up I might have a chance of fixing it....

    These Tdis are great for fuleeconomyand power but....

    Must be the week for it Bernie....:(

    Dropped the SAAB off for a service on Tuesday, to find a timing chain tensioner is stuffed..........

    Having all the bits in there replaced whilst it's apart. Maybe ready sometime next week, and around $3000.....:confused:

    That is a shame Bernie - have you tried approaching VWA Customer service? They came to the party with my T4 when it was just out of warranty - I can't quite remember what it was for - it could have been the reverse gear idler

    I'd be trying for a warranty claim for that.

    Sometimes they give you a goodwill claim and there is also the new expected life consumer laws.

    We have had some issues with VW over the last 12 months (lennock motors inparticular ) I wouldn't let them change the oil in a two stroke lawnmower let alone touch a motor vehicle.

    Just by not dealing with a VW dealer for most of the regular services we have saved more than the cost of the repair.

    I could go on about the pathetic service offered by them but the point of the thread was too raise the issue of the EGR valve failing not only on VW's but as far as I can tell all the modern turbo diesels.

    Failures though seem to be mainly associated with the cooler corroding and leaking coolant into the engine.
    The sulphur in the fuel I suspect is the issue associated with short trips - the Amarok takes ages to warm up so the sulphur in the exhaust mixes with condensation in the cooler and just eats it out..

    A longer journey gives allows the moisture/acid to be flushed away before it causes a problem. Whe we first bought it we were doing a lot more trips to the farm which is an hour away but for the last 18months we only head out there maybe once a fortnight.

    I remember having issues with the revers idler gear - actually it was the spring that held the selector shaft for reveres gear that broke - but I think it was at about 300,00km.

    I've heard of that a few times.

    Wouldn't Moss Vale be closer for you?

    It is just, and they are much better but we still have to twiddle our thumbs for a day while they do what they do.
    They also charge like wounded Bulls.
    So dealing with the local mechanic is far more economical in cost and time. ( the guy we have been using specialises in euro cars as well)

    Now it's out of warranty I'll end up doing the servicing now any way - we just got caught this time as we had a few other things going on and I didn't have the time to do it immediately.

    I never had VW do my servicing on my T4 (except for the first service) and always had it done at my local guy - they (the dealer) only ever saw me for warranty issues - or when I took it back to them after they broke something when they were fixing it (which happened twice).
    VWA still came to the party with a goodwill claim.

    We the same, VW place don't touch the Golf, have a mechanic that I've known for 25 years. He has been servicing what ever car we have had . He also is break and tyre specialist. All tyres come from him also. My last service was $65, I supplied oil an d filter.
