Here is some interesting info

996 606 124 00
A new version is
also available (less sen-
sitive to dirt particles)
#986 606 125 01

 

or a 930 we built!

 

Hehe I remember the video of that one

 

Mass Air-Flow Meter (Sensor)...

MAF/MAS - It is a primary metering sensor component that detects the amount of air entering the engine. It typically sits just after the air filter intake.

 

Thanks! I am not good with the tech talk.

 

OK folks... here's what I found out thanks to Brian at Carslen. If you buy the new and improved MAF you need to get reprogramed with the new software update via the PTS2.... Brian will take car of it for those of you in the Bay Area.

 

Alex just got that thing replaced on mine yesterday. I spoke to the tech at Stevens CP and he said that he does not touch the ECU. He said when they go bad you end up burning up the CATs due the air/fuel mix being FU.

I did not know they were that tempermental however. As always you Brits always add some nice color to an otherwise common statement. Thats why you speak ENGLISH so well. It's been mastered in England for thousands of years. We Americans are still at the elementary level in years speaking english.

Always like a nice narration from a Brit.

 

Hehe thanks so much Robert. I do love going off once in a while. The funny thing is it's ONLY in America where people have found my stuff interesting. In England, I'm just another boring Journalist but for some reason, in the US people were so much more willing to adopt new technology (which is why I did my web site in the first place and still write for Magazines over here). I guess what I'm saying is it's thanks (or no thanks) to the Americans that I get to spout so much fluff!

I'm glad it got taken care of yesterday. So you do have the new style MAF then? It's a "Boxster" part number and is angled differently at the inlet. I'll take a pic.

PS Cats? What cats... I don't need any cats

Your not getting oil blowback through your air filter are you?
That kills MAF's.

 

Nopes I've checked for dat... Good idea tho

 

Alex,

Can you please tell us how you really feel?

 

I hope that isn't a direct Porsche quote. I can believe it's
a more durable MAF, but the idea that something in the
intake tract is being destroyed by dirt particles belies the
existence of an upstream filter that blocks all dirt above
a very small size. I wonder if this MAF failure syndrome can
be associated with the use of freer-flowing (more porous)
filters that may be letting some bigger stuff through?
If I truely found the MAF failing due to bombardment
or sandblasting by dirt, the first thing I'd do is eliminate
the dirt. There's much more expensive stuff to worry about
than MAFs...

If that was the case then stock cars would show this issue. We see it on all of them, 996, 986 and TT. We also do a lot of VWs and Audis. They too suffer from the same set of problems. It is a design flaw.

 

Cool, so we agree. It's not dirt, it's basic frailty in the face of
simple air flow. This would mean that the harder the car is
driven, and the higher the power mods are, the sooner/more
likely it would be to damage this part, right?

 

Not really. You would think so but it is more like this. Some never fail, some do. There is only one pattern linked to airfilters and oil. It is almost a QC issue I think
