Hi all, I am a newby so if anyone can help it would be much appreciated!
I bought a 2004 SE Diesel Freelander last July, after driving for a few months I came to the conclusion I either have a fuel leak or a very thirsty Freelander! After a bit of research on here I unplugged the MAF sensor and the difference was amazing in power and general running of the engine. I have since driven with it unplugged until last week when I came across a MAF sensor on Ebay for £35.00 (Aftermarket) I plugged in at the weekend hoping to feel a massive difference in both the drive and fuel economy. However, I have spent the last 48 hours smoking out West Sussex!! With the new MAF fitted the engine runs lumpy and sluggish and both black and white plooms of smoke seem to be coming from the exhaust. I decided to drive the Freelander for several miles (55 to be exact) in case it clears but to no avail…….

In a nutshell should I have just bought a genuine MAF or is there something else I should be re-setting? Or after driving the Freelander for so long with the MAF unplugged I have broken something else???

Any help would be very much appreciated.

Aftermarket MAF sensors generally don't have a good reputation.

However, these people have a good reputation:

Digimafam, Tuning-diesels digital maf compensator for Bosch & Pierburgh mafs

I ended up getting a Pierberg (Mercedes) MAF from this website along with a RonBox 2a.

The OEM Bosch MAF is quite expensive.

Epi thank you very much for your quick reply, are you able to tell me if I would have done any damage driving with the MAF sensor unplugged for so long?

Anyone else have any thoughts on this one as I have to drive from West Sussex to Surrey tomorrow and dont fancy smoking out half the South East on route?

Without the MAF, it just runs on default settings as I understand it, probably less likely to do damage than your aftermarket MAF.
Others will correct me if I'm wrong.

buy a pierburg or bosch one. aftermarket 3rd party maf meters across manufacturers are generally crap. poor mpg, black smoke and they dont last very long but like most things in life, u get what u pay for!
