Recently my engine began to idle really rough constantly fluctuating and causing the car to shake. This then brought on the Engine management light.

I changed the coil packs but still had the same problem.

I then changed the PCV which has seemed to fix the rough idling. I then disconnected the battery which turned out the engine management light and stayed off for two days but then it came back on although the idling is still fine?

My cars a 55 plate 1.8t A4. I then got the codes cleared and the engine management light reset properly but after another two days the light came back on with the following codes:
16891/P0507
Idle Control System
17700/ P1292
Map Controlled engine cooling thermostat-F265 open circuit
17544/ P1136
Long term fuel train add.fuel bank1 (If anyone could help I would be extremely grateful)

Thanks for your reply.... Any ideas why these would all come on at the same time? from the fault codes links I am thinking possibly a vacuum leak?
