Hello, I have a problem with my Zafira C 2.0 CDTI, the car runs well at low revs, but when hold the engine in high revs the check light comes up and car goes in limp mode. ECU stores P2270 fault - MAF sensor performance. I removed the MAF from the car and clean it, also checked all pipes and didnt find any leaks. I checked the MAF values in live data and seems ok, but I noticed that MAP sensor actual values values are lower than desired from the ECU. Also checked for the leaks around the MAP sensor, but cound''t find. I would appreciate any help if anyone is faced with that problem.
