4.8i Behaving Strangely - Codes
Checked for codes and these keep coming back: 2D32 - Differential pressure sensor, plausibility error 29F4 - Catalytic Converter Conversion 2B70 - Variable Induction Mainfold 29F5 - Catalytic Converter conversion bank 2 Where i live 99.97% of the X5's are diesels, few petrol engines, and theres my 4.8i. So the dealership and shops usually give me a hard time with this particular issue and did not know what to do with it. Any suggestions? |

I recall on this I recommended checking the DME unit. Have they looked into that ?

However if there's no other solutions, they've thrown enough parts at it might as well throw in another one and see if it resolves it. |

Since you're getting a code from the differential pressure sensor, have you tried replacing that? It's in a bitch of a spot to get to mounted to the rear of the manifold, but it's a hell of a lot cheaper than a DME at around $85.
Also, if it is working properly, and giving such a code, have you confirmed that everything is properly sealed up? No air/ vacuum leaks? You might want to plug the throttle body and smoke test using a fitting to put smoke into the oil filler cap. Unmetered air can cause all sorts of drivability issues. BTW Blue Point (sold by Snap-on) sells a stretchy blue rubber universal oil cap with a fitting to attach a smoke machine in the center of the cap that does work with our cars.

My 4.8 had some higher than normal rpm issues, sent it to shop but they couldn't find anything, smoke tested but no leaks. No idea what's going on. I bought another car now, I think I am going to sell it off now, I give up.

I’m getting close to that point now. Mind asking what car did you choose.

They swapped two throttle bodys trying to fix it, issue persisted.

Changed the differential pressure sensor, i haven't checked for codes yet but the car is behaving the same with the bucking and hesitation but limp mode is getting activated much more frequently. I also noticed the car was needing much more frequent refills, calculated it and on average it's getting 8.2mpg, on a good day 9mpg, this is normal driving with a few pushes here and there. The Catalytic Converter conversion bank 2 error came up last time randomly, might it be an oxygen sensor that is bad, but not bad enough for it to throw a code? |
