My 1998 Passat has been my pride and joy and I have never has a problem with the car. It is serviced every 10,000 without fail.

I recently had a new battery fitted ( yes it is the correct one).

The car will start and idle ok whilst auto choke is operating however as soon as you get to a corner or roundabout the car simply stalls.

Spoke to a mechanic who said take it for a long drive and it may reset the computers. No luck.

The question- is there anyone with sufficent computer equipment to be able diagnose the problem or do I need to take out a second mortgage and go the local VW dealer. I am based in south west Sydney near Liverpool however prepared to travel for the right person. Any recommendations would be very much appreciated. Thanks.
