BinksyBinks Posted May 22 Share Posted May 22 Hi all. Audi a3 2008 2.0 tdi. Black smoke on acceleration and diesel smell, slight whistling sound . Plugged an obd2 scanner in. No fault codes but maf reading a lot higher than it should be. Could this be the culprit for the smoke and smell? Any thoughts? Thanks Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 22 Share Posted May 22 Very likely. You might be able to clean it rather than replace it, but I'd wait for others to chip in first. Quote Link to comment Share on other sites More sharing options...

Thanks Hi black smoke is due to over fuelling, the high MAF reading is due to the ECU trying to combat the extra fuel with more air, so you either have a leaking injector or the car has been remapped at some point.

Rybrook Posted Friday at 11:27 AM Share Posted Friday at 11:27 AM When was it last serviced? Plugged airfilter will also cause black smoke and a loud sucking/ whistling Quote Link to comment Share on other sites More sharing options...
