[s-cars] S4 Avant

[Josh]

The jhm timing chain kit for this car is $4500.  

To go through the trouble of yanking the motor and not replacing everything is false economy.

My friends b6 s4 threw the cam code and even though the motor still ran, it was toast.

If you throw a timing chain/cam related code on one of these, it's game over.  That's why I say there's no warning and you need to proactively replace the chain etc.

Shop labor is dependent in region and relationship, but $100/hour is to be expected, with quotes varying from 20-30 hours...

Note if you need this service, you may not need everything so it doesn't have to be the full boat.... but yeah I know "if you are     pulling the motor do it all when you are there just in case..."

The vast majority start to break down and car runs like crap and throws codes to indicate it needs the service - all will need eventually we can presume. Yeah for the one or two guys who had the catastrophic failure it sucks and you'll hear them screaming about how it happens to everybody and it's a miserable fatal engine design and every single one is just waiting to self-destruct at any minute.   But talk to techs who work on these all the time and it seems that is the way rare exception - codes and poor running and limp mode come up first almost every time.
