Have a 2005 AXX engined golf gti.
Cylinder 4 is misfiring. Constantly.
What I have done so far:
changed coils around plugs around, follows cylinder
checked triggering of coil and injector, all TOK with my test probe
replaced injector
checked wiring back to ecu for coil and injector-ok
compression test done, all cylinders 190+/_ 5 PSI
checked cam timing, replaced camshaft adjuster unit
replaced cam sensor
Engine still misfires on cylinder 4.
at idle the following measured values are:
091 cam adjustment bank 1=39-42%, specified KW =24.0, actual =23.5. 39-42% at idle seems high?
093 phase position bank 1 intake=-1.0kw
203 Ign timing, is all lover the place +18ATDC to -4 BDC, not sure if this is because it is running on 3 legs?
Throws no error codes apart from misfire.
Do not know what is going on and have run out of ideas
