The problem was the left FRONT turn signal - bulb was burned out (must have been a slow burn out because it was blinking when all the left-turn signals were blinking really fast).
I would not have found it if not for your help! I had given up on bulbs and was thinking in terms of the switch or an electrical problem. Now I know VW lights and Christmas lights have a lot in common.
FYI - I received my Vag-Com interface and ran a scan of all fault codes on the bug (it's my daughter's car - she just turned sixteen last weekend). This Vag-Com is awesome. The fault codes found are:
- 16502 (P0118) Engine Coolant Temp Sensor (just ordered tonight from Autozone). Must be a common problem because I scanned a 2002 bug for a guy I work with today and it had the same fault code.
- 17608 (P1200) Boost Pressure Control Valve. Autozone couldn't find anything on this but they were sure it was in the turbo. Before I take it to a dealer I am going to run a can of SeaFoam in a tank of gas to see if it solves the problem. Previous owner ran 10% ethanol blend (89 octane).
- 01330 (no P code) Central Control Module for Central Convenience. This one has me stumped and will probably have to have a dealer fix.
- 00595 Crash Data Stored (previous owner hit a deer).
- 01214 Crash Data for Belt Tensioner Stored.
- 00589 Airbag Igniter 1, Passenger Side (have a salvage air bag ordered, old air bag blew a hole from the deer).
- 00654 Seat Belt Tensioner Igniter, Driver Side.
I ordered the Bentley Shop Manual (on CD) for VW New-Beetles today. My wife bought a 2003 VW Beetle owner's manual off of EBay which should arrive tomorrow. I bought the 2003 bug (31000 miles; GLX, 1.8 Turbo, with the sport leather interior) for $11,000 knowing the above problems (or at least symptoms like the check engine light and rapid left-turn signal).
Thanks again for your help Hako! You are VW Bug Wise!
