Hello, \nI 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. \n\nI would appreciate any help if anyone is faced with that problem.
