Multiple Misfire detected on my Audi S3 8P. Wanted to know which output tests I can run to pinpoint the issue. How do I tests injectors with obdeleven. How do I check flow of petrol from tank to the engine or fuel rail. Please advise

Hey, for you and anyone else stumbling on this. You can go garage > your car > gauges and check the fuel ones. Also in the engine module you can view live data of cylinder misfire.
Likely though, you'll need to replace those injectors. You can get lucky with second hand ones that have been restored but you are best to replace them with new ones. There's plenty of stores online that do new for £1000 for 4 which have the upgraded metal baskets and all fresh seals. You should replace the 2 seals as well on the inlet, engine side and inlet side as they are cheap.
You can also get the valves walnut blasted to remove the coking.
You can definitely diy this if you're handy but be forewarned you need a lot of patience and a clever head with no prior knowledge of this job. I've swapped engines with more ease.
It's been said time and time again to not skimp on this job. Do it right, do it once.
