I changed coil packs and spark plugs but still there is misfire. The mechanic done compression test and it is all good. He said maybe injectors. Could it be camshaft sensors.? Esp light came and parking brake fault but gone. Audi A3 2013 1.4tfsi 65k miles

Did the Esp light and parking brake fault flag up so you turned ignition on then disappear straight away?
Asking because mine did this other day think due to battery being low.

Sorry buddy i don't have knowledge like most on here, So can't really help you.
I'd say just get it to Audi Vw specialist near you. Sometimes just best to let garage sort it.
Don't think low battery cause misfire, so something else going on. Again I could and probably wrong.

Hope you get sorted simply.
