Hi all, I'm trying to track down a misfire issue with my stock 2008 S3 8P on 106,000 miles. It started to run a little rough on idle and the mpg dropped down by about 5mpg at the same time. Once it warms up the rough idle issue almost disappeared.
I changed the plugs (NKG) and then new Bosch coil packs and there is a misfire on cylinder 2. There's no engine light and I've swapped the plugs and coil packs around and the misfire remains on cylinder 2.
I've got a full version of vcds and the only error showing in the engine is this misfire. I was wondering if there was any way of checking whether injector 2 was starting to fail or what to check next.
Thanks.
