Hiya,
I've got a 2003 Audi A6 1.8t (petrol), AWT engine. About a year ago it developed a mis fire, along with the engine management light illuminating. The AA came out, and diagnosed the fault as a coil pack failure - so I replaced that coil, and the other 3. Everything was fine.
Fast forward to the past couple of weeks - the engine management light has come on again - took it to a local garage (useless place, now I know) and they said that it was an 'unknown fault' - cleared the memory, and its back (no suprise). A mate of mine works for the AA, and he plugged his computer into it, and the following came up:
Fault code P0353, Ignition coil C, Primary/Secondary Circuits.
A bit of digging on the internet shows it might be a circuit malfunction, and the DTC (whatever that is?) is 16737.
He cleared the code - checked the plug gaps (all ok), and all the coil pack connectors (all ok). The light then came back on.
The car drives fine - no misfiring, fuel consumption is the same, starts and runs great. The problem is I don't really understand what the fault is - would anyone on here be able to suggest what it might be, and how I might be able to fix it?
Thanks in advance,
Biker_billy.
