I've got a 2008 Audi A3 2.0T petrol that's got an intermittent electrical fault - radio goes on/off, window auto-up/down resets, clock resets, and central locking opens and closes. Everything else seems fine, and tends to misbehave in the first mile or two, then settles down. Did 250 miles without a peep yesterday. Today, on a 2 mile run, the whole lot went full cycle.
I gather this could be one of a few things - ignition switch is possible according to the Audi-sport.net forum. I've charged the battery - didn't take much on the charger and it seems OK. Any other ideas?
I've been looking at a code reader in the hope of identifying the fault properly, and it seems the one to get is the Ross-Tech VCDS/software - about £270. I don't mind (well . . .) spending that if it works and has a reasonably shallow learning curve. Any opinions?
