Audi A3 Coding List

[Domenec Reynolds]

Hiall Its been a while, I have just bought my second S4 B6 for a Smyth Ute Conversion, This one has come with a few (lots) of fault codes, some of which i know what they are like engine mount solenoid ect. but there is some i have know clue what they are or if its one thing failed causing a few codes linked to that unit that's failed, i have done a lot of searching online and found out what some are.

Hi Steve, Thank you for your reply, yes that's what I read on a few other posts, no the carpets are dry but it has that faint musty smell, so I'm sure it has been at some point, and the ECU cover has no screws in it at all lol, so I'm just going round fixing all the half baked jobs other people have had a go at. Why people can't just do a job properly or not do it at all is beyond me.

If there's a musty smell I bet the battery drain holes in the scuttle panel- engine side bulkhead were clogged. Water then escapes through the holes in the bulkhead right where the CCM is ultimately frying it. Worth checking nthe area regularly to prevent it happening bargain.

Hi Steve, yeah that was my theory about the CCM, when I went to collect the car it had been stood far ages and the battery kept draining because the aux fan was constantly running, I had my vcds with me, he put a new battery on and I braved the 300 mile drive home, since then the aux fan has acted normal, no draining, Car starts first time on the button with no chain rattle, put it sown to all that nice heat from the engine bay drying things out on the run home, I did clean out all the drains around the battery and ecu box, and still the ccm fault code so like you say its fried, also I checked the the relay for the aux fan as that's ment to be a problem when the drains block, now for the hunt for a ccm and info on coding it lol, you got to love audi.
