Any BMW experts (N42 Engine)
Evening all, I've had a bit of a crappy day. The wifes 2004 BMW 318 (2ltr) broke down on her way to work in Sheffield. She got RAC out to have a
look after shouting at me  The car just died on the way into a car park and then wont start at all I asked her to ask what the fault codes are if
he plugs in his OBD reader.
One of the codes was p0366 which is camshaft sensor. Luckily he got it recovered for us back up home so I can repair it.
Normally I would dive straight in but as luck would have it I had to set off down south 220 miles for a training course today so while watching crap
on the hotel telly I thought I would do a bit of remote diagnosing and ask the collective experts for opinions.
Before I set off and left it I plugged my diagnostic into it to see what came up.
2B63 camshaft sensor exhaust
2A83 inlet vanos 1
2A63 valvetronic servo motor 1
so I cleared the codes then tried to start it then 2A63 came up again.
I know these engines are a pain in the @rse with tensioners letting go and timing jumping a tooth or 2.
The engine still seems to have compression as the starter doesnt throw it over any faster than normal so hopefully no valve damage if it has slipped a
lot.
It did have a new valvetronic servo motor fitted about 6 months ago under warrranty when it kept going in to limp home mode but has since been
fine.
The RAC man thinks its a sensor but I thought I would see what yer think. Is there a quick easy method of checking timing on these engines? Links to
diagrams would be helpfull if poss.
Ill just after wait till Saturday when I'm back home to dig in and find out for sure but any usefull tips and short cuts would be most welcome
for dianosing this bloody over complicated engine!
cheers in advance

The eccentric shaft is what is driven by the vavletronic motor or sometimes called the eccentric shaft servo motor. They are a common failure on
these engines as ours did. There is also an ecentric shaft sensor . They are effectively controlled by the thottle pedal as I believe these engines
dont have a throttle body or butterfly. Instead the mount of air let into the engine is governed by the servo motor moving the eccentric shaft which
then varies the amount of inlet valve lift. Combine this with the vanos system which has solonoid valves to hydraulically control advance and retard
of both inlet and exhaust camshafts.
Told you its a bloody complicated engine!
