2002 A4 2.5 quattro 180Bhp.

esp light comes on frequently whilst driving, light stays on for approx 5-10 seconds, during this the car gets sluggish, the light goes off and car goes back to normal. vagcom shows up this error

00550 - Start of Injection Regulation

Just after replacing the needle lift sensor about two months ago, this problem has just started in the past two weeks.

Anybody have any ideas whats wrong

Thanks
in advance
