Hi all,
To all having a D2 with a reluctant MAF sensor, I post here what I have searched/found. You all have helped me so much, specially Chris, with my misfiring, Low power issues that I will try to help you, even if I'm across the pond.

MAF part # BOSCH part #
ERR7171 (D2 4.0) 0 280 217 532
MHK100800 (D2 4.6) 0 280 218 010

According to LandRover's own Micro cat, both are interchangeable. When mine did fail, the dealer didn't have a replacement (it was 3 weeks before and it still has not arrived). Not a very common part in Spain.
But... they had the MAF from a Rover 75 CDTi (2-litre BMW engine). They dissassembled the MAF and. Voil?. Part # of the sensor itself equivalent. Not only it looked as if it would fit but it fitted. No more fault codes.

Sensor itself Bosch part # F00C2G2029.
Pierburg manufacture MAFs for many cars and have a cross-references, but this one is not listed. I will try to find another from Pierburg that fits and works (Merc E-Class and Vito for instance). Watch this space!

Regards

I just got a quote from Repco for a MAF (Part # 0 280 217 532)...AU$531.

I noticed Robert, that you mentioned a sensor (Part # F00C2G2029).

Please enlighten me:

Is the MAF a whole unit with the sensor inserted and it's only the sensor that stuffs up, so all you need to do is replace the sensor and not the whole unit?

I had a look on the net and found the following:

Would something like that do the trick?

Cheers and TIA

Hi, Erron,
The MAF Assembly consists of the sensor and its housing, all together as one unit. The only thing that fails and needs to be replaced is the sensor itself, but... the sensor itself is not available separately....they want to bill us for the housing as well. Some Pierburg replacement ones are available separately, much cheaper, but I've got to check compatibility. I have been told by a workshop in northern Spain that Pierburg MAFs last 2 times longer than Bosch (in VW Tdi engines. They fit the Merc part).

Changing the MAF sensor unit (sensor+housing) is just a matter of unclipping the electrical plug and the ducts, and swapping units.

But... changing the sensor itself you will need a special torx 5-pan screwdriver. The bolt itself has a pin in the center to prevent a normal torx screwdriver being used.

Jeffrey, you listed a VW MAF as a fitting unit, as direct-fit replacement. Is that the Tdi one? The Merc Vito Series and C,D,E,S-Class270 and 320 CDI seem to fit, too. Another thing is if they are compatible and work as they should.

VW-Audi MAF Tdi Pierburg part # 722684080
Merc CDI MAF Pierburg part # 722684070
These part # can be considereably cheaper as no housing is bought. But... not warrantied to fit or work. Jeffrey said the VW fits, I expect to be this one. I only used the old said "it will fit if it looks as if it will fit"
These parts are the sensor itself and you should use your old housing. Blow old housing well to keep it clean. When fitting sensor itself it hasan arrow which points the air flow direction. Be sure it is fitted the right way round Otherwise your rover will go crazy.

You will need the special dismantling tools. Erron, the link you supplied me with was the same I have listed as the Merc part. If you zoom the photo you will see stamped in the sensor the part# I told you.

It looks nearly the same as the Bosch MAF of my V8.

Good luck and best regards

Robert

FTR, We use 2 seperate MAF units on Bosch engines. Range part is almost $400. D2 part is about $160. Same innards fit both. We use the D2 sensor on the Range when it's customer pay, as it's half the price for the same part.
I cannot say with 100% certainty that all these are interchangeable. I should look into it, it would be nice to reduce the customer cost on this frequently failing part.
The gas VW sensor is interchangeable with the Diesel sensor on some models, 2000-ish vintage. It is also interchangeable with the MB sensor on some models.
I swapped a bad MAF from an MB once, (V12) and it set the usual 171/174 codes on my D2. It ran fine, as they usually do, on the Bosch Disco, but it set codes. There was no change on the MB V12 with my good sensor on it, as it had an engine harness and two ECU's full of oil.
The VW Beetle MAF is cheapest here in the states, about $35 or so. It would be worth a shot.

Jeffrey,
Then the VW MAF you say is a direct-fit in the Bosch housing, and does not throw any codes? This is great! It would be great to know the specific model and I would search the Pierburg part # cross reference.

I will keep you informed.

Best regards and thanks again
Robert

Robert: Thanks for that info...I thinks me might have to get a new sensor if my wire swap doesn't fix my mis-fires...

Jeffrey: Yes, if you can get a code for the VW MAF and it works with a 99 D2 and doesn't trip any codes, this sounds great :) Better than paying AU$531!

Cheers

Hi all,

Correct me if I'm wrong, but have we the correct Pierburg replacement for a Bosch MAF sensor (Part number F00C2G2029)?

When searching the Net, this was found:

http://www.tdiparts.com/catalog/product_info.php?products_id=243

They mentioned that this sensor works with the BMW 320D, 525D, 530D that use the Bosch F00C2G2029.

Robert, you also mentioned the Merc E-Class and Vito...well, if you look at the following URL:

http://www.msi-motor-service.com/download/schadstoffreduzierung/int/sr_aa01_appref_web.pdf

...it mentions that the Pierburg 7.22684.07.0 works with the E-Class and Vito. Now this is the same number stamped on the Sensor in the first URL I mentioned.

Based on this cross-reference, do we have confirmation that a Pierburg 7.22684.07.0 is a direct replacement for the Bosch F00C2G2029?

Cheers

Erron

Erron,

I think you are right and that the Pierburg part # you list is a direct fit for the Bosch one.
there can be just a slight problem... The Bosch MAF has a built-in temperature sensor which measures air temp. I was told by a Rover 75 cdti MAF swapper, who by the way manufactures and sells an add-on to the MAF and measures air temp, but I do not think this will be needed in a V8, it's for the BMW Tdi engine.

But if Jeffrey told the VW (and BMW, MErc, MAFS are the same) and work , and the Pierburg guy says it's a direct fit for the F00C2G2029, I would give it a try.

Good luck and best regards

Hi Robert.

I've looked at the specs for the Pierburg 7.22684.07.0 and it *seems* it comes with the temperature sensor. It lists this as optional, however I'm assuming it means the ECU has the option to use this pin 1.

Here's a couple of URL's:

http://www.x-desk.net/ximages/6166_pgpi0020en.pdf
http://www.x-desk.net/ximages/21302_pgsi0079en.pdf

The second URL lists some general OBD info and testing procedures that you could prob. use for the Bosch unit as well.

Tomorrow I'm going to test the Bosch unit and make sure it's not 100% dead. If it is dead then I'll be ordering a Pierburg 7.22684.07.0. If it's not 100% dead then I'll be ordering a MAFAM MF1p (from http://45zs.info/75Zt/R75maf.htm) to boost the signal coming from the Bosch unit.

Cheers

Erron

I am assuming when you say "a direct replacement" it means the plug from a 4.0 2000 model will fit as well?

Hi Erron,
the links from Pierburg absolutely rock! I did not manage to find them, well you found them for us! Thanks a lot! Hope your test performs OK. We look forward to your report

Ditto, when it stops raining I will put my MAF thru the test outlined on that site. Someone who knows how ought to put that stuff on the technical board.

Hi all,

I have spoken to Pierburg Australia and they are coming back to me to confirm if Pin 1 on their sensor includes a temperature sensor. If it does, then the 7.22684.07.0 is a direct replacement for the Bosch unit, if it doesn't then you will need to purchase a separate IAT (Intake Air Temperature) sensor and plug this into the side of the MAF housing.

Here's info on the connectors:

http://www.members.aol.com/roverron32/carpics/Homepage/pierburg.htm

Here's some pin information:

http://www.geocities.com/tech4tdi/pages/maf.html

Here's a comparison between Bosch and Pierburg:
