Recently brought 2012 R56S Auto. On the way back after purchasing noticed white smoke is coming from exhaust when car is idle in traffic and start runing. Dig the few mini forums and everyone suggested about PCV valves. I had few short runs for next few weeks and then all of sudden error appeard for "Engine Power Reduction". Took the vehilce to mechanic and found error code for 2d5a - Vanos Intake Control Fault. They recommended to replace both Vanos solenoids along with Valve stem seals . Later they call me and informed they have found time chain debris and recommended to change time-chain and also to clean the oil sump. ( with a hughe bill of 11 hours of work , $150/hr , total $3900 ). So I asked them to go ahead with all those repairs as needed. Now, they called me again and saying there's a new error 0033FE & 003406 showing ( which never had before). Are these mechanics playing arround with me? I saw on some threads some meachnics failed to remove whatever labels in TC and it caused the blockage. since they have already cleaned the oil sump, and put new engine oil & filter, new TC what might causing this? I dont wanna pay anymre for them as everytime they will come with new error and ripping off me.

I have to say… That’s the worst looking N18 engine internals I’ve seen. Someone was not taking care of that car. Sorry to hear you’re heading down a rabbit hole with that car.
Those last two codes (33FE and 34p06) suggest that the oil control solenoid needs to be replaced. That’s the solenoid on the oil pump. If the problem persists, then replace the oil pump. With all those timing parts in the sump, and general condition of the inside of the engine, it doesn’t surprise me that the oil pump is having faults.
