Maf

Is there a cheaper solution for replacing the MAF than buying it from the dealer for a 1997-1998 540i? I found the threads about the VW MAF but from what I have read that is only for the post 1998 models.
Thanks,
Craig

I can not comment on the vw mod as I have never done it but , We do offer the oem bosch maf on our website.
I assume from your post that yours was built before 09/1998

MAF from a 2002-2005 Range Rover with the 4.4L engine is supposed to use the exact same unit at half the price of the official BMW unit. I've read that the e38 guys have been using them for some time now.

I know this is an old thread, but rather than start a new one I thought I'd just post here that I can now confirm this first hand. Ordered one Tuesday and it came yesterday. Bosch Part #13 62 1 433 567 stamped on the housing. The only difference is that it came in a Range Rover "Genuine Part" box. $158 out the door (no tax or shipping).

Be careful where you buy them though. A few sites list them cheaper, but some may be made by Lucas which is a British electronics company (now owned by TRW Automotive) not exactly known for their reliability and one of the OE suppliers for Range Rover parts. If you look at the fine print on the sites, MAFs are excluded from their return policy and they won't verify the brand other than to guarantee you it's a "Genuine" part. Scott at GetCoolParts actually checked for me to verify that their part was Bosch and if for some reason the part that showed up was not, he'd take it back.

EDIT: This only applies to 99-03 e39 540s with a production date after 9/98. If you have a 97-98 540 or any year 525/528/530 e39, this part will not work for you.

Went through the same thing a few months back ... BMW Dealer $500.00 (no thanks) picked up the range rover Bosch part for under $200.00

And now it looks like it is cheaper!!

I have the range rover part in my car. The part looks identical. All the markings and part numbers were the same. Cost me $128.00

I bought the VW one for $79 from the dealer. That was two months ago and haven't had a single issue with it. I just used my old housing and put the new sensor in it. This forum is a big help for saving money. I also bought new O2 sensors from NAPA with the same part number at a fraction of the dealer cost. Good luck with your endeavor.

actually, you can make the the newer style vw maf work in a pre 99 e39 540. the main difference between the two mafs is the the iats(intake air temp sensor) was integrated into the maf begining with my 99. you have to match the wires up, disregarding the wire for the iats. this has been done successfully.

Did you do this and have pics, or is it a "I have you heard" situation?

I put a Range Rover MAF in my '99, and it's been working 100%.

I'm not saying it's not possible, but I've seen sketchy ones come off eBay. Make sure to let us know how it works out in the shoft and longterm as I could probably use a reliable replacement myself eventually.

Good find, but the OP of this whole thread is a 4.4 owner, not a 2.5-3.0 owner. Posting that would be the same as me bringing up that 99 and up 4.4's can use VW MAF's for $90...it's basically a teaser to us non-VANOS V8 owners.

I'm relatively new to the E39 world and have not seen this before. Are you saying that my 03 540 MAF can be replaced with a VW MAF ???? If so, what is or where do I get the part #'s ?

Nicely setup 540iT. Yes, we can use VW MAF's for far less than BMW or Range Rover versions. As for the part numbers, it's been forever, so I'd suggest searching around on www.m5board.com since it's the same part and they're the ones who discovered it. I'm sure "VW MAF" will find you the results you want, then repost it here for the hell of it.

Beware. You're asking for big trouble with cheap Chinese MAFs. Do some research- you'll fine that the hot wires on these things are not made to spec and will change resistance over time, jacking up readings.

Autohaus and a variety of other vendors sell a genuine VDO-Siemens for $200- it's not really that expensive, and it'll last another 100K. Just think about it...

I'd certainly start with MAF cleaner before purchase of a new one.

Not to say it won't work for you but I tried that route and it didn't help. It is cheap enough to try, at least.

Cleaning a MAF is like cleaning sparkplugs...they both get resistance over time, so you're only putting off the inevitable.

Temp -- what was the part # or model make/year that you bought? You bought this for a 540 correct ?
