Undercar Repairs on 1996 to 2005 Volkswagens and Audis
Just as we get used to the types of powertrain, suspension, brake and exhaust systems that are coming into the marketplace, something different comes along. In this article, I’ll take a look at the designs and repair of the suspension, brake and exhaust systems of Volkswagens and Audis from 1996 to 2005. I won’t be able to cover everything in this article, just some of the highlights of the various models.

Tech Tip: Volkswagen Instrument Cluster Malfunction
Instrument cluster malfunctioning on affected vehicles may be caused by a poor connection between the instrument cluster and the wiring harness due to poor wiring-to-terminal crimping or improper terminal tension.
Volkswagen Tech Tip: Crankcase Breather Whistling/Howling Noise
On some 2001-’02 2.8L Passat models (ATQ engine code), a whistling/howling noise may be heard from the crankcase breather valve at idle. This problem may be caused by routing of the connection hose (rubber) between the breather valve and the intake manifold.
Tech Tip: Volkswagen Diagnostic Trouble Codes
Diagnostic Trouble Codes (DTCs) P1580 (Throttle Actuator B1 Malfunction) and P0103 (Mass or Volume Air Flow Circuit High Input) are simultaneously stored in DTC memory. The problem may be caused by an attempt to start a vehicle with a dead or low-charged battery.
