Good evening y'all,

Had some MAF issues on my LC 20VT - came up as a 16486 code when I first got it.

Took a while to replace because I travel a lot, then had the car housed for near 6 months.

Fired her up upon my return and the EPC light flagged up. Had a duff battery, so called out the AA and he plugged it in to say something about the acceleration pedal .. and being restricted to 2000 RPM - I blushed when I told him I'd taken it for a spin to get some charge into it, and 2000 was the least of my worries :p

He kindly reset it :)

48 hours later the Engine Management light came on, figured it was the MAF as that had been previously diagnosed problematic - so replaced with genuine Bosch.

Almost the same day, the double unlock (Unlock drivers side, then knock again for the remainder of the doors) stopped working.

EML stayed on for 4 days, then cold start one morning and it had vanished.

Got a cable in between time to double check any faults - cheapy thing off Ebay - currently running VAG-COM Release 409.1-US

Connects fine, port has mapped okay, finds interface etc.

Ran the Auto diag across all controllers to find any fault codes, and it came up with this (excuse the bad image - had to use my phone)

Does this mean I'm clean?

Acceleration has improved, no more juddering, but the central locking is still duff

Should I reset, and any clue on how to achieve this on the cheap-o software that I have?

Any assistance would be gratefully appreciated :)
