Hi and greetings from Sydney Australia.
Just got a new HEX V2 so I want to introduce myself and 'Claudia', my 2001 Audi A4 (B5 8D) 1.8T / APU Engine. For several weeks, she's been running poorly, and stuttering both on acceleration and cruising. My first thought was a vacuum leak and I did find a cracked check valve, and the diverter valve was kaput, but this didn't help. A local workshop (also using VCDS) found an O2 sensor alarm - a new sensor cleared the fault but not the performance issue. At this point I got my own VCDS and started playing. Groups 002 and 032/033 are pointing me toward a bad MAF...002 readings are in spec at idle, but low gr/s when driving (fluctuating between 5 - 14 at around 2000rpm, and 17 - 24 around 4000rpm); Group 032 fuel trim is indicating +2.8% (add) & +14 to +25% (mult). I gave the MAF a thorough spray with CRC MAF cleaner, but still no better. To seal the deal, I disconnected the MAF, and the stationary throttle/rpm response in Neutral was now linear (no stuttering around 2000rpm) but stuttered again with the MAF back in play. So I've ordered a new MAF, and fingers crossed, it'll sort my issues.
What puzzles me though, is that my Auto Scan didn't show any error codes to this effect. Is this normal? To be fair, I'm new to this code scanning (more of your ol' school socket and wrench mechanical fault finder) so I may not have set up the scan correctly. Any suggestions greatly appreciated. Anyway, really excited about playing with my new Ross-Tech tool, and learning more about the car. Below is my Auto Scan.
Cheers, Stephen.
