I only just last week bought into the A2 family with a 2000 1.4 petrol AUA and just over 100k. I can say its been an interesting few days.
So - I have a misfire on cylinder 2. Typical ( in as far I have read ) issue in that it happens generally on idle.
Have replaced plugs and coil, cleaned throttle, played musical chairs with the leads, replaced injector 2 (electric plug came off on removal). Compression test shows really high in all 4 (14 bar). I thought the replacement injector did the job but then on a run out it comes back - quickly followed by the battery light o the dash (with power steering and then ABS failures). Battery changed but issue came back within 5 minutes. So the Alternator (or other elastictrickery) isnt doing its job. Alternator on order with a new belt. Question to the experienced - could the alternator have been causing the misfire (or helping it with the damaged cables on the injector 2?).
Will find out in a few days when i replace the alternator but thought I would post it as I didnt see the alternator side of the elctrics being mentioned in the other posts I saw about misfire (no doubt its out there somewhere - but the posts on misfire tend to look at the high voltage end rather than the low).
Engne flush and lifter treatment to come in case its a sticky valve and the alternatr was just coindcidence.
