what do you think i should just replace both vanos and call it a day. Thanks! have you checked compression? The Huntingtons collection of the history of science is one of the largest and most important in North America, with holdings ranging from a 13th-century Ptolemy Almagest manuscript to modern civil engineering reports and aerospace archives. I am trying to figure if I should start with replacing solenoids or cam sensor. - Nick at Pelican Parts. Sounds like an engine misfire. They need to be tested using an amp meter. And if it is a vaccum leak, where do i need to look? They can help you find the right part. It could be displaying it wrong. tried to restart engine several times, til battery drained. Unplug both coolant temp sensors, the fan should come on immediately. CAN ALL THESE BE A RESULT OF MALFUCTIONING OF THE SOLENOID? No sense in replacing them if they are not broken. Start by checking the oil level, then oil pressure. what are the VANOS angles - actual verse desired? Let me know bye, The fault codes are not complete. You usually hear a new noise and can play with the visible wastegate - the other faces the engine and is impossible to get to - to check how much play it has. When I removed the intake solenoid, there was an O Ring, but the spacer was missing. Since car has nearly 90 miles I decided to simply replace both camshaft sensors and both vanos solenoids. Oil level check using the display no dip stick situation why did BMW ever did that indicates OK. nothing to add. To confirm, use a scan tool to check fuel trim. If you have an oil leak down the front of cylinder head, inspect solenoid area for fresh oil. Is that the normal value? 2A80:
2A80 inlet-Vanos variable cam control test, input signal
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Timeout
2A99:
2A99 crank shaft - outlet camshaft, correlation
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Short circuit or signal interruption
I am pretty sure the cam position sensor is bad as moving it from intake side to exhaust side caused the error code to move to the exhaust side. Next day I got DSC and brake warning lights so I ran a Carly OBD2 scan and codes present are 002A98 - Inlet camshaft, correlation and 005E46 - Steering angle sensor. Errors found at diagnosis:
29F3 - Fuel Low Pressure Sensor Electric
2A26 - Catalytic Converter, Conversion in stratified - charge mode
2A2D Fuel Low pressure, fuel pressure
2A87 Exhaust Vanos Mechanism
2A99 Crankshaft, exhaust camshaft
2AAF Fuel pump, plausability
2C31 Oxygen sensor emissions control
Any idea what should I do next. COuld be a defective parts, things happen. Thanks! Action in service / P0012 1. - Nick at Pelican Parts. I changed both as the car was going into limp mode after driving and parking for a while wouldn't happen after engine had totally cooled down. Does this confirm that the solenoids are bad ? If problem wasn't present before working on solenoids, you are likely in the right area. You need to use a scan tool and fuel trim to test for a vacuum leak. I took it to my mechanic and he cleaned the vanos solenoids for me. I am thinking it's the oil pump that has failed. Confirm engine oil level is OK> If so, the issue is likely worn timing chain components. I am sure they saw debris, etc, which is why they want it changed. Could be fuel delivery or engine compression if not ignition. Parents reported issues .. rough idle at start.. ECC shaft motor thing and gasket etc has been done.. oil and engine gaskets were done.. solenoids were cleaned/swapped and put back in. Any ideas?? - Nick at Pelican Parts, hi again - vin a101812. its common for engine stall when removing oil cap as it dumps the vac crankcase pressure to inlet manifold,, very common is rocker cover pcv valve to fail this causes bad idle and running lean,, also on turbo cars the inlet valves get coked up do to the pcv system,, highly recommend fitting oil catch cans to both breathers and must be sealed that I am going to revise the fitment etc if it does not work, what do you suspect? - Nick at Pelican Parts. It could be pulling down the entire system. Haven't been driving the car as much recently and generally keep the tank full so wondering if it's just bad petrol/ I need a replacement part?

Engine runs smooth and has great power but now idles at around 1200 RPM. Hasn't thrown a code, started with new plugs and coils and attempted to clean the MAF sensor but it loks like it may be slightly corroded pitted. Will try cleaning the solenoid sensor as you recommend but wondering if there is any way it could be related to an ignition coil that is going bad. The Huntington Library is one of the world's great independent research libraries, with more than 11 million items spanning the 11th to the 21st century. I am scratching my headwhat else it can be, if you have spark, compression and fuel - you would not have a misfire. The N54 engine is known for needing turbos every so often as the wastegate actuator gets some slop in it and the ECU can't control turbo pressure properly eventually going into limp home. 05-17-2017, 08:13 AM . Then check mechanical timing - Nick at Pelican Parts. Sounds like a possible engine timing issue. If this was fine for about 3 months, then I'd think I could replaced both solenoids and hope for the best? The engine was fairly cool. 2008 335i - 2A87 - Exhaust Stiff/Jammed Mechanically Fault. Janie's Mr Pelican has helped me with parts and Nick with taking them apart. The Huntington holds 900,000 historical prints, posters, and ephemera that date mostly from the late 1700s to the 1960s. Don't have your vehicle here in the US, so I can't be too specific. Also can the brain box and oil sensor cause this issue? Also the rpm is not regular. If the coolant light is also coming on, there may be a faulty level sensor. Thank you. - Nick at Pelican Parts.
