Would anyone know where I should start lthe "fault finding process" to sort a problem that occured last night.

The car was fine until I floored the accelerator on a bit of a hill. Soon after the turbo spun up, the car had a couple of fairly violent kangaroo type jolts.

I backed off the throttle and it was it if nothing had happened.

I then tried again on a flat bit of road, and once again after the turbo begins, the car did it again !!!

I have never had this in the S2, so don't really know what it might be. Any suggestions ???

try searching for "boost leak", many threads and solutions to your symptoms..

and also try "overboost protection" .....

As above, its boost cut, and suggests either a leak or something related.
First thing I would try is disconnect and reconnect the MAF plug afew times, it can clean the contacts

Thanks for the advice guys.

I used the car to get to work today, and it behaved the same again. I will have a go at the MAF connector first to see if its the offending item.

Dest, you are a star...

I pulled of the MAF plug and reconnected it a few times, and voila - the car behaves itself.

Had to give it a few "test runs" to make sure, which upset the Mrs a bit. Caused her a bit of difficulty with texting !

Thanks again for the advice. S2's are awesome when they are running right.
