When I bought my CDTi, it felt pretty â€œflatâ€, as if the turbo wasnâ€™t coming on properly. I discovered the MAF
had been disconnected, so of course connected it â€“ didnâ€™t make a vast amount of difference to be honest.
After much discussion on the other forum, I bought a new sensor and fitted it to the MAF
â€“ it made a big difference, brought the car to life. I donâ€™t want to get into the argument about whether theyâ€™re necessary or not â€“ I really wouldnâ€™t know â€“ all I can do is tell you what happened with me.
PS subsequent to that, there was more argument on the other forum as to whether the sensors which were available separately (ie rather than buying the whole MAF
) were the correct one for the Rover. Marinabrian, for whom I have the utmost respect, said definitely not, and it would overfuel by a few percent â€“ yet, when PhilT4 checked it with his T4 (Testbook version 4.Computer Diagnostic System)
, he said the readings were perfect.
So make of that what you will! At the end of the day, my car doesnâ€™t run well without it. Thatâ€™s all I can say for sure.
