-and if anyone has any suggestions as to why our 04 jetta tdi chase car runs on 4 cylinders when cold, and drops down to 3 when it warms up, let me know!
Unimog406,

Just a guess, but you may have a clogged injector. The symptoms may be masked when the engine is cold by the cold idle circuit. Then when it warms up, it is going back to the normal idle setting which shows up the problem.

Good luck
