Hi All,
First post here.
Have had an unbelievably frustrating time with my 2012 116i F20. Running out of ideas on what to do. Have searched the forum's but can't find anything similar.
The car has had a fair amount of work done to it, all by a very experienced BMW Indy.
New timing chain, new oil pump, valve stem seals have been done.
Recently, the car has been throwing a drive train warning but only under very specific conditions. It occurs when the engine is warm, and has been restarted and left to idle without moving for around a minute. Restating the car after getting the warning and immediately driving off clears the error and am able to drive around fine with no loss of power. The warning won't reappear at all unless the car is turned off and then on again.
The only other indication that something may be wrong is that there is a bit of a shiver (is the only way to describe it) feeling on idle. It also behaves quite weirdly on a completely cold start (first thing in the morning). It seems to cut out and has no power if you touch the accelerator in say the first minute or so while it warms up. I've read this cold start issue can most likely be fixed with a software update so maybe unrelated?
Error code is 130304 - exhaust camshaft stuck.
Have replaced both vanos solenoids as well as the exhaust vanos gear, unfortunately without fixing the issue. Running out of ideas and don't want to just play an expensive game of parts roulette.
Any assistance of where to look would be greatly appreciated.
Thanks
