Default p0102 Solved after three long days

My 09 X358 threw the code p0102. I scanned it and it said low voltage on the maf. Checked for leaks (none). I then removed the sensor and swapped another. I reset the code and this is what happened. The first start up after code is reset car runs great. I can drive 500 miles and the light wont trigger. Shut her off. On the second cycle the code pops. Car runs perfect still.

So I again reset the code. This time I also reset the ECU. Start her up no codes. Now I went in deeper with my scanner and found the p0102 pending.

Second cycle and boom it pops again. I went back to the auto parts store and showed them. I know if the sensor is not OEM it can confuse the Air readings. I then traded that sensor for one with a lifetime warranty. DL-3000 I believe it was. I screwed it in, scanned, no codes. And this time no pending p0102.

I knew the issue was fixed 100%

Im so happy my car is back to normal. It was very frustrating. I kept telling myself the car is not smarter than me. I will figure it out. I now know how sensitive these sensors can be and a slight difference the way it was designed will cause problems. Hopefully this info is helpful to others. The aftermarket MAF DL-3000 is a perfect match for this vehicle.

Anyhow its a beautiful day in Vegas

How did you reset the ECU? Nice car by the way.

Along with many others, that code needs 2 trips to set. (Mandated by US and other laws, and documented by Jaguar and others.) So, at least you were seeing what should occur and hopefully it's now fixed.

I cleared codes first with scanner and then I just disconnected the battery

Thanks for info buddy. Actually to think of it I could of asked members here and probably wouldn't have had to struggle with it for three days. I'm glad I was able to figured it out eventually

Beautiful car. Did you ever find a problem to create the codes? I needed to replace one small oring on one the small plastic tubes

Yes in conclusion it was the MAF sensor. I guess the one I got originally was defected for being brand new. Swap it out with the different brand (DL-3000) and all is well again.

I know how important those O rings are. I actually changed all O rings within the TB and intake hoses, added one to oil dipstick as well
