That's my 2001 S4, got it Taxed and MOT'd on Saturday and went for a decent run on Sunday, have a few issues to sort out.

- Front brake shudder through the lever, new discs should sort it out.
- after market rear sets need a bit of work to get the positioning where I want.

But the main issue

- revs to about 6500 quite cleanly but then hits a brick wall and doeasnt really want to rev any further, like it's choking / hesitating

Monsterman / Jerry - you mentioned you have an S4 with a similar set sup, is yours 955cc and do you have anything you reckon could be the issue.

Thanks

Welcome Davey,

It could be any of the following:-

Fuel Pump Assembly plumbing/Blocked fuel filter restricting fuel supply
ECU faulty
Crank Position Sensor faulty

Well those would seem to be the most likely candidates to me. Has it got a power commander? That could be another possible.
