Hi all. Retrieved a code using VAG-COM from 1997 A4 1.9 TDi (110) as follows;
00550 - START OF INJECTION REGULATION
17-10-CONTROL DIFFERENCE - INTERMITTENT.
Any ideas?

 

Hi, welcome to the forum. We will be able to help you with general and electrical issues.

Most of us however are US based and the TDI is not imported here, so most have no experience.

You may be better served with one of the VW message boards as the TDI engine is available here in VW.

Sorry
