Hi guys im new in bmw scene.


I bought an 335i and i am having problems with boost... when i floor it the vanos code P0012 comes up camshaft position 1 overretarded...



I replaced the spark plugs and coils.. and replaced the oil filter and cap oem BMW.... ( yeah also the insert in middle of oem filter was fitted) but still nothing..

Also fitted new vanos selnoids 2x and camshaft sensor....


Oil is full and oke...


I dont understand what it can be... sometimes the car drives perfect also ful power turbo no problems... and sometimes even if you start and put it in drive the code appears....


Like today started the car drove it on temp and then full power until couple kms and again limp mode.. or sometime it comes and stays....


Im running out of options some one advice?
