How Do I Buy The Correct Maf Part Cheaply?

[MrT]

I believe that my MAF is not quite right due to rough running giving and out of range readings on VAG-COM and it may now be the time to change it. However after reading many articles on this forum and not finding the exact details, I am trying to work out the best way to get the correct new or exchange MAF.

 

My understanding is that the MAF consists of a small cartridge with a sensor that is held by two torx screws into a larger plastic molding that looks like a piece of drainpipe crossed with a throttle body that sits in the main air intake hose. Correct so far?

 

The options I believe are to either by the complete molding with cartridge either new or exchange or to buy just a new sensor cartridge?

 

Now what are the differences between all the various models of Sharan, Galaxy and Alhambra as far as MAFs go? Is the cartridge the same in them all and it is only the main pipe body that differs?

 

Apart from buying from a Ford dealer at about

The MAF has a part number on the underside ,you have to remove the maf to see the part number.This is what you need if replaceing the whole thing.I bought mine from e-bay...you can get them from various places, but you will need the part number as there sre many different kinds of maf.

Drive to GSF, remove said maf with housing, open front door of GSF, approach counter... :lol:

[MrT]

OK I have taken the MAF out and to bits.

 

The body housing has the following on it:

 

PBT-GF30

Bosch

0 280 218 017

071 906 461B

 

The MAF Cartridge has:

 

PBT-GF30

F 00C 2G2 032

184 10 3 B

 

and I see there is one on Ebay

shhhhhhhh! they'll all be bidding on it :lol: :lol: ;)

[MrT]

Are the MAFs on ebay genuine Bosch parts or other manufacturers equivalents?

 

I have asked a couple of sellers as Bosch and VW numbers are given but whether they are genuine originals is not stated. I await their replies with interest.

 

Any good or bad experiences or warnings specifically on buying MAFs off ebay?

[mumof4]

I bought my bosche one off ebay..the seller was very understanding and answered all my questions.I did post on the forum who i got mine off.

[MrT]

Mumof4 can yhou remember who it was? I tried a search but "MAF" is too short for the search engine.

[mumof4]

[MrT]

I have been looking at a few sellers on ebay and it seems that some of the MAFs are OEM. Are these worth it at around

[mumof4]

At the end of the day the decision is yours to make.I had no problems with getting mine off e-bay..it was delivered within 24 hours of me paying for it.Some on here have bought from dealers..some e-bay etcc..I paid

[MrT]

It is not the Ebay I am questioning, it is the OEM vs Bosch for quality of product.

[mumof4]

Im sorry i dont know....i went with like for like part.A bosch one was already in the car so that is what i got.

[Brookydave]

I also got mine from ebay - about

[Scorpiorefugee]

I noticed a reference to the Pierburg replacement.

 

I went for one of those a few months ago and it's been fine. They are also supposed to be more durable than the others but only time will tell.

 

It was the cheapest on offer and works happily on a 98 110tdi and a 52 115 tdi.

 

Obviously, I can't comment on the suitabilty for a non diesel.

interesting - same model one year earlier

[MrT]

I phoned around a few places that sell MAFs and it appears that the majority on sale are now after market replacements made in China. They actually have the Bosch part number stamped on them.

 

I emailed several people on ebay asking about the MAFs they had for sale that look like genuine Bosch parts with Bosch numbers and oddly enough, none of them replied when asked if they were genuine Bosch.

 

It appears that the UK distributor of these after market MAFs will send them directly to the consumer with an invoice from whoever is the middle man.

 

No one I phoned would guarantee that a new MAF would be a genuine Bosch part so in the end I just went for the cheapest new one from a "retailer" for

You are right MrT, the MAF on VR6's makes little difference to performance, it does however improve MPG slightly.

 

Why would you be surprised that reducing the torque loading on an engine at a given speed would allow the ECU to lean the mixture.
