Advice please on purchasing an Air Mass Meter

Mine has the same P/N (094 00 48) and is made by Pierburg. As stated in the last article, it can be removed very easily by removing two small torx screws and extracting the unit from the air filter casing.
I remove mine regularly and give it a blast with an electronics component spray (do not use anything else) to clean off any crude which is usually a light oil deposit. Just hoping this will extend its life and avoid the outrageous £60 replacement cost.

Do you know where I can get one of these Pierburg probes from to fit the (094 00 48) and it has the round cable connection not the square.

Thanks for the info.

I can now see how the probe is separated form the black tube, but the other problem is that the torx screws have those annoying anti tampering pins in the centre of the screw head.

I'll work something out!!
You can get security-torx bits from your local market tool stall for under £5.

So much for the "security" aspect then!
 
Strange, my unit of the same P/N has a rectangular connector with a small locking tab that you press in when you remove the connector, it is multi-pinned so I assume there are some electronics within the plastic casting which probably accounts for its high cost.

I think this is my problem, because the cable connection on my MAF is round and not square may be the reason why I'm having problems getting either just the probe or a cheaper MAF altogether.

GSF just got back to me via email and the only MAF they have for my car costs £172.50 + Vat.

Looks like I'm going to have to bite the bullet on this one.
 
Update.

Air mas meter faulty, so, one new MAF, a service and a few other things looked at and cleaned.

Result, car is good as new.

Also, one other thing I forgot to mention, sometimes the kompressor wouldn't work, twice this happened to me but with the new MAF it shouldn't happen again.

Thanks to all for there help,

Cheers
BigDusty.

Check the air bypass valve motor on the air box. These first go lazy then short out, taking out the ECU.

After reading others post that was my first thoughts. I asked MB and they said it was fine so I will have to take their word for it for now.

Is there anyway to check this part myself and if faulty, can it be taken apart and fixed or is it a case of replacing the whole thing? (Wondering if I should start a new thread for this question)

Thanks

It seems strange that the same P/N should have two different styles of connector and two different unit prices. If it's the identical P/N then I suspect that it has the same functional characteristics and can be used providing it can be installed in the airflow pipe and connected electrically. My only suggestion for changing the connector is to contact Pierburg directly or a car breaker, MB is unlikely to make one available to you although you could try (just say yours has fallen apart and needs replacing).

The following is an excellent doc on the Pierburg unit.
 
Sorry, file was too large and the system has dumped it.

in manchester a bosch agent can obtain parts most mbz parts have a dual bosch code as well (if they are mabde buy bosch )
you do not need the special torx tools just drill the middle out and use a hex set and job done the best fluid to clean the sensor is wait for it diet coke yep diet coke
see the ford owners web site i used diet coke om my c220 before patr ex and defn improvement

Just wedge two terminal screwdrivers down the side of the anti-tamper pin and unscrew the screw.

Nice tip on the diet coke, it's the acid working to clean the elements. As has been said before, what the hell is that stuff doing to ones insides??
 
Update to an update.

Car is running allot smoother, idling is much steadier thanks to the new air mass sensor, but the kompressor once again cut out, or should I say didn't cut in when I needed it.

My suspicions are pointing towards the Air Recirculation Flap but I'm going to start a new post with this problem.

Again thanks to all for there help and advice and no doubt will be needing more very soon.

Cheers

I rang up a bosch uk supplier S C Motor Factors Ltd (Forest Hill). And asked them for price on Bosch# 0000940048 but he came back to with Merc# 0280217100 & quoted £267.00 + vat

I asked him why I can't hav the Bosch version as I heard its half the price. he said its because I don't hav an account with Bosch.

Where can I get the Bosch version from??:confused:
 
Sorry if this is a bum steer, but I did read somewhere (would have been either here or the other MB forum) recently that MB has dropped the prices of these as they're considered a service item now.
Have you checked the MB price?
