About Robert Greenfield Expertise I can answer any question pertaining to B5 model Passats short of automatic transmission rebuilds. I may be able to field some questions about other late model VWs with crossover engines. I do not address performance modification questions.
Experience I have been doing all my own work on my two Passats for a decade. I have been giving sound repair advice on PassatWorld.com for the past few years.
Education/Credentials No relevant auto related degrees unless a BSME counts.

Question My daughter's Jetta has an alarm that seems to go off randomly at times and recently, when the lock is opened with the key and the alarm appears to be off, it activates when the ignition key is turned or when the hood latch is popped from inside. HELP!
Answer There's a micro-switch in the lock mechanism that tells the CCM that the door was unlocked. VW has had issues with broken solder joints where the connector meets the circuit board in the lock mechanism. Reflowing the solder joints usually fixes the problem. If you take the mechanism apart, I'd suggest taking pictures as you disassemble it.
