I have a 2008 A3 1.9 TDI sportback with the standard audi double din concert radio. I would like to upgrade to a DAB radio but don't want and android touch screen thing, a proper radio that will fit and work in the car. There are no steering wheel controls. Anyone recommend anything that is plug and play or as near as can be? Thanks.

Hi Gareth. All input is welcome. 👍 When I left it unlocked in the garage it was after having it running. I don't think it locks itself then, only when you unlock and not open a door after 30 seconds or a minute or whatever time it is. Yes I have the handbook and a Haynes manual so can identify all blade fuse locations and what they do. I did wonder about the alternator and did disconnect the small wiring connector and no change but I need to test with all wiring disconnected. Will be down the garage tomorrow to do more testing. Thanks.

Yes that will be another, the starter motor circuit (probably the 200 Amp fuse?), the alternator and there are 3 more.

Hi. Sorry for the delay, other stuff happening. This car does automatically lock after a minute (or less, not timed it) I think if unlocked and then no door has been opened. Can anyone tell me what circuits are on the fuse links on the front of the engine bay fuse box? I guess one may be to the alternator but don't know about the others. I ask as may have to disconnect them one at a time to see what happens.

Thanks guys. 👍

Thanks for your reply. (1) The parrot is a Bluetooth hands-free device for a mobile phone. I have disconnected it fully and found no change. (2) No other added non factory accessories added. (3) Boot light with holder removed, wires are insulated. (4) I have removed the fuse for the alarm system, no change. (5) I will be doing this again, I did do it but may have missed one or more so will write a list and check them off one by one to be sure.

I don't think there is as all looks OK but I will bear that in mind when doing even more investigating. Thank you. Thanks Gareth. I haven't checked the glovebox light yet but will do. The boot light is missing as my brother removed it in the past thinking it was that setting the alarm off, I have not seen it in the car so can rule that one out. No satnav in there either. all extra pointers appreciated as it is easy to miss things.

Meter reading when locked and after 10 minutes.

Ok had another quick look today and the current drain remains at around 500mA after locking the car and waiting a while. I tried it with the fuse for the center convenience unit out and no change. I cannot remove one at a time when the car is locked so that makes things tricky. The parrot bluetooth thing only comes on when the igntion is on so that's not a problem so something is drawing around 0.4 to 0.45 Amps. I do have an issue with the ESP and steering as the lights are on the dash. Just waiting to get the code reader again to get the errors logged in VCDS.

Hi Gareth Thanks for your reply. The current drain of 1.7 Amps stayed constant for quite some time when unlocked and after any courtesy lights had long gone off. I am not sure if fully solved but my friend was right about the current drawn will drop when locked but yes I will still investigate further. There is nothing extra connected to the battery but there is one of those parrot Bluetooth phone things in there which takes it's power source from the fuse box inside the car, I will remove it as not keen on it but I didn't suspect that has been any issue. Will update further as and when i get further with it.

Found what it was thanks to a mechanic friend of mine. The battery drain when the car is left unlocked is quite normal so me leaving it in the garage unlocked for over 3 days drained the battery. I put the meter on the battery and locked the car. within a minute the current drain went from 1.7 Amps to 500mA and would have dropped more I think but I unlocked the car again and it went back to 1.7 Amps.

I recently saved a 2004 A3 2.0TDi sport from being scrapped by my non mechanically minded brother to hopefully fix up and the first problem I want to address is a constant battery drain of around 1.7 amps when everything is off. I took out each fuse one at a time to try and narrow it down but no significant drop noticed so wondered if anyone else had similar and what was it? A scan showed an issue with the steering and convenience unit, I don't have the exact log at the moment, will have it scanned again soon to see what it showed exactly. It did have the usual problem with the micro switch in the boot catch but that has been resolved for a while. Can anyone suggest what to take out of circuit to help find the battery drain or any other suggestions? Thanks.

Hello everyone. I joined here as I took my brothers poorly Audi A3 from him when he may of scrapped it so I want to try and fix her up if not too costly (Audi not costly?? 😂) Will be looking for help and advice shortly, I know my way around a lot of cars but not had an Audi before. Thanks. 👍
