Here are a few pics of the MAFs I purchased from Ebay. Bosch on the left in the pics. I got them from seller E-Europarts. I am having the same issues as in the post here>>>> http://www.m5board.com/vbulletin/showthread.php?t=106043. ei.. stalling,and rough idle. My car has even shut off twice while parking. I've also thrown a few codes such as; P0101 Mass or Volume Air Flow Circuit Range/Performance Problem, P0171 System Too Lean (Bank 1) P0174 System Too Lean (Bank 2) P0175 System Too Rich (Bank 2)
I wouldn't suggest purchasing this part from Ebay.:nono: Especially if it may cause your motor to not get enough fuel. How do you know if these MAF are even right for the E39 M5 with no labels???hmmm They may look the same but, Bosch... I think not.
Hmm, those definitely look suspect. I would suggest getting them from the company I bought mine from or someone else who got them from a reputable source. Sorry to hear you got screwed...can you return them? I'm betting a no return policy on electrical parts. Find the thread called cheap VW MAFs. You'll be able to find the guys I got mine from on there.
Good to hear. Hopefully you still have your original parts to put back on. I'd recommend pull them off your car yesterday and not running them a second longer.
..love to see a pic of down INSIDE the opening of the actual sensor area.
...macro feature on your camera?
I had a set once which gave me the same problems, when I looked down inside the opening at the sensor, I saw a completely different construction than the Bosch models.
as mentioned in the other thread, IMHO I'd only run the BOSCH -032's...
I would just feel uneasy buying suspect MAFs on Ebay. When it comes to something as important as the MAFs, I would spend the extra cash for something I know is Bosch. $345 or so for Bosch MAF's in my mind is worth it.....no headaches involved and your M5 will perform better. cherrsagai
I guess I'm out of $160 however, maybe it will save somebody from spending $20,000 on a motor. I decided to take the sensor apart and OMG!!!!oohhh: Look at this!!!! Bosch is the one with the circuit board of course. RMFD SHORT ENGINE 11001407803 $20,445.12 +core
The KEY thing I noticed when I bought a "look alike crap part" was that the real sensor part was completely different, and easy to miss if you didn't look...
So look at my attached picture (sorry -400k), its an OEM MAF... ...ZOOM in on the pic -to the opening... down inside is a small metal bar (may only be there to protect the sensor) the sensor is just behind it.
On the crap model, there was only a folded piece of aluminum instead of the material you see on the OEM... :grrrrr:
I'm trying to capture all our collective experiences with the eBay MAFs so we can work out if anyone has got these to work or not, and if not what the symptoms are.
If you have bought the eBay MAFs and not posted your experiences in the thread below, can you please post a short note. Thanks.
Since you are already out the $160, how about you peel back the black stuff. Are you sure there is no circuit board behind it? Looks like a protective cover to me...
If you look the sensors have different clips for the wire harness.
Also that thermistor looks sketch to me in the cheap MAF.
