Creator C110+ codes on my 01 2.5i

[SilverbackGuerilla]

Hey yall,
I have been pulling my hair out trying to match these codes on the Creator C110+ to those in multiple service manuals with no luck.

I purchased this car a couple months with 170k miles as a project car to restore it back to health as well as modify it on a budget a long the way. I am hoping to do all the work myself, building knowledge and confidence. Since purchase I have gradually replaced parts. Upon receiving the Z it was stalling at idle and overall down on power across the power band. Throwing lean codes in both banks 1 and 2.
As of now i have replaced:
Spark Plugs
Valve Cover Gasket
Upper/Lower intake boots
Air filter
Fuel Filter
Camshaft Position Sensor
Refurbished DISA Valve
vacuum lines and caps (minus CCV)
cleaned MAF
as well as the soft top, rotors,pads,lower control arm bushings and many cosmetic issues but thats a whole different story!

After each replacement part the car has regained power but is now having a rough idle upon cold start and will sometimes still be hesitant in the lower rpm range. While being hesitant in the lower RPMs you can hear what i believe is the exhaust valves timing being slightly off timing. The hesitation is audible in the exhaust tone. Has any one else experienced this? So now the codes have changed and im left with these codes and I am having trouble finding the equivalent BMW or P codes. The car has yet to leave me stranded but I had a couple of scary moments when it went into Limp mode untill the car sat and was turned off.

My current train of thought is that the vanos seals are worn affecting the timing and throwing the camshaft position sensor code and causing the hesitation. I received my vanos seal kit in the mail today and will be knocking that job off my list this weekend. I also think it may have something to do with either the fuel pump or injectors as well.

Any advice or links in the right direction would be much appreciated as I am new to the BMW world and trying to sort out this M54 engine.I have searched the interwebs more times than i can count and am about to break down accept defeat and bring it to a shop. Let me know if i forgot to mention any valuable information.

Thanks in advance!

You may have cleaned the Maf but is it working? Can you view live data from it showing how much air is passing through it. If the Maf is bad cleaning it rarely fixes it and often kills it completely in my experience. Downside is they are expensive but only fit oem makes Bosch or Siemens do not throw cash away on cheap pattern parts they seldom work or last long. Bad Mafs don’t always throw a code.
Disconnect the electrical connector at the Maf and see if the car runs any better, it will revert to factory standard setting with it disconnected.

Hi

You're still getting an inlet camshaft sensor error. Did you fit a BMW branded sensor? If not, buy one, sensors are not the place to skimp on as the after market ones usually end up being replaced all too soon.

Yes is sounds like the VANOS seals are toast. Hesitation and cackle in the exhaust are common symptoms as you have indicated.

You're still getting lean codes, even after all of the vacuum leak prevention work you have done. Lean codes come from the DME seeing too much air or not enough fuel.

Pulling the MAF electrical connector off can result in:
1) Car idle comes right indicating vacuum leaks or incorrect reporting from the MAF

2) Car idle stays rough indicating a good MAF and you have other problems

Hope this helps

I would definitely start with the inlet cam sensor.
