A little help here. I have read the threads on this P1419 code and I have also cleaned out the Valve which was heavily sooted. After cleaning the valve and checking the hose I cleared the code and SES light was off for about 2 days. Fast forward to today and fooking light is back with the same code. Unfortunately I do not have that secondary MAF shown in the picture above on my 2002 3.0i, what I do have is part #6 in this diagram:
Can someone with a pre-facelift E53 that has had this code share in their possible solutions. TIA!
