The cold start injector has a "thermo-switch" and associated relay within
its operating system.
Any one of these components, as well as a bad ground, can cause the problem
The "stock timing" (according to Bently) is 6 degrees BTDC at idle(900rpms).
Audi's "customarily" run lean. If your Audi looses power above 4000 rpm,
your timing is 3 degrees ATDC, then these two problems are probably related!
Your intake system may have an "air-leak". Your fuel pump may be going bad.
Determining the exact malfunction, is a "process of elimination" Having an
Audi repair manual is a "MUST", especially for electrical problems!
When was the last time the air filter was changed? Plugs?
