So apparently there are two part numbers now for the TT MAF? the one in my car is:
Porsche #:996 606 124 00
Bosch #: 0 280 218 009

And the one i got from Autohaus Arizona
Bosch - 0280218055

Porsche - 98660612501


The issue I have is that I put the new part in yesterday and when i drove last night had high idling problems which seemed to go away after a while - and today it was idling high again threw the code for "high idle at stop" or something similar (i can look it up if necessary). So when i got home i cleared the code and started back up and seemed fine, but then started doing it again. I then swapped back to the stock software map (using UMW software since Wednesday) and that didnt seem to make a difference, but then when i swapped back to the 1bar map, it wouldnt even really idle - like would stumble and die and then lit up an ABS Failure, PSM failure, etc. and when i ran the code again it gave a MAF failure.
I swapped back to my old MAF - Bosch #: 0 280 218 009, and it seemed fine. No high idle or nothing.
Could it be a faulty MAF? or do i have another issue? I have hoses on the way which will be swapped by Thursday, so i suppose if i have a vacume leak I will know/solve it then, but i was just wondering if anyone had any experience.

BTW - I had thrown that error code once before as well with the old maf, where it had idled a little high, but then didnt seem to be an issue again - probably a week or so ago. thats when i ordered the new maf.

TIA

 

Porsche - 98660612501 that looks like a boxter maf 986=boxter

Yeah, that thing was the wrong MAF, getting RA# from the retailer.

BTW - The MAF referenced in this post is not the right one - https://www.6speedonline.com/forums/...ight=maf+price
Make sure to ask for the Bosch #: 0 280 218 009

Looks like this place has the right ones listed for about the same price - www.europartsdirect.com

 

Actually there have been 2 updates to the MAF:
996 606 124 00 is the first version of the e-gas sensor, and was put in new e-gas cars until January 31, 2000. Then the "improved" second version 986 606 125 00 went into production, and that part number is now superseded by 986 606 125 01, which I will call the third version....from Renntech (per tool Pants and Lauren...I think they know their sh*t):

Renntech post on correct MAF.

The one I linked to is the correct one...I have been running it without incident.

 

Wonder what the deal is then Bill? any ideas? Its running fine back on the old MAF (although i dont think that one has too long left). Got new hoses on the way, but seems odd...

 

Okay - so in that post i see this : If you put in the second or third versions in a car that had the first version then the DME has to be reprogramed. Porsche no longer sells the second version as it has been replaced by the third version.

what has to be done to reprogram the DME? could that have been the issue?

 

Villains, I can't find the MAF when I do a search on eurocarparts.com? Do you have a direct link?

Thanks

 

Get it from searching the part number - i was using the bosch ones, but you can use the porsche ones too I think...but see above, it looks like the one from autohaus may be right as well but i have to reset something to make it work in a car with the original 009 bosh part number.

 

Isn't that the 986 MAF? Eurocarparts.com says it's for:

"AIR MASS SENSOR 996 02- & 986 WITH M620 OPTION
air mass sensor (PORSCHE 911 Carrera 4 3.4ltr (996) >2001 model 01/01/1998 - 31/07/2005)
air mass sensor (PORSCHE 911 Carrera 4S (996) 01/01/1998 - 31/07/2005)
air mass sensor (PORSCHE 911 Carrera 2 3.6ltr (996) 2002> model 01/01/1998 - 31/07/2005)
air mass sensor (PORSCHE 911 Carrera 4 3.6ltr (996) 2002> model 01/01/1998 - 31/07/2005)"

Not the turbo...

 

Villain, I would say stop by and I'll hook up my durametric software and read your codes....but I'm on my way to Chicago right now. I did not do any re-programming of the DME...I would still say there is a possible leak somewhere, but without codes we are just guessing. I get back Friday and would be happy to swing by to take a look.

 

I actually have the durametric. The code when i swapped the maf originally was 'idle control at stop', i cleared that and then it was stumbling and would die after idling for a minute or two (this is the case in stock map mode too so its not an issue with teh umw software). Then the abs/psm lights and the code was a for a bad maf or maf failure (cant remember exactly). Swapped back to the 124 00 and it was better.

 

What is resetting the DME? how do it try that?

 

This RennTech thread says that the TT should retain the 124 00 maf part number - http://www.renntech.org/forums/index...opic=414&st=60
...ugh.

 

Do you know what your original part number was then...cause from the stuff i was reading on renntech if you had the 125 00 in there, then no update would have been necessary for the 125 01.
Im cool with trying to exchange for an 124 00, but if there is a reason for the update - like a better maf, then i would rather do the new one...

 

So , Which Bosch Is The Correct # 0280218055 Or 0280218009?
