Ok, I am fairly certain that it's my MAF sensor, or air mass meter (whatever you want to call it), is at fault on my BMW. The problem being though that from GSF this part alone is £160+ and I don't really want to fork out that much cash on something that potentially doesn't work. Does anyone else know of a good place that sells genuine Bosch or Siemens units for a slightly smaller price?
What model of BMW m8?
My m8 has a breakers yard specialising in audi ,vw and bmwget me some details of the car and ill give him a call for you .
I'm after a new one preferbly mate, but it's a 1992 BMW E34 525i with the M50 engine
I cant seem to get a hold of him at the mo , ill let you know as soon as i speak with him
Is this the one your after ? http://www.elcome.co.uk/xplorerlite/...&sFromApps=yes

get the bosch number off the old unit......and any details ..
I can try our local bosch agent , and see how much to post..
If so £103.69 + vat....Originally Posted by Leigh
do you have the bosch number ? , he has a few of these and would rather match it up with the Bosch No. if hes got 1 it will be £20 + P+P
That link doesn't work for me Leigh
That's a good price Mud, I'll try and get the Bosch part number tomorrow morning or afternoon, are these guaranteed to work though? I'm guessing it's second hand?
Was that price including a surcharge for an exchange unit as i'm sure they are an exchange item or at least vw were
The price i gave was out right, some of the VW ones do have a surcharge as you can buy just the sensor part so they use the old housings works out a bit cheaper that way.
gsf just sell the sensor too.
it will be second hand aye , most of his parts come off running cars , i can pm you his number if you want and you can discuss , hes a top bloke and im sure if you had any probs he would seeya all right.That link doesn't work for me Leigh

infact heres his ebay shop http://stores.ebay.co.uk/A-V-B-GERMAN-CAR-SPARES
Cheers for that! I'll get in contact with him and see if he's got any lying around. I looked on the top of my air mass meter this morning and the only numbers I could see without removing the whole unit was PBT-GF, which doesn't sound like a part number to me. £160 for just the sensor is nuts from GSF
Link again seems to work on my screenThat link doesn't work for me Leighhttp://www.elcome.co.uk/xplorerlite/...&sFromApps=yes
And this is the complete unit with a 4 pin round connector on the top.
I can see it now but there's no price next to it, looks like the same one though
No prices on there as its a online catalogue we use @ workI can see it now but there's no price next to it, looks like the same one though
up to 9/1992 gsf have em on the shelf at £78.50 +vat 187BM0111 is the part number. if yours is after 9/1992, then its the expensive one....
18789c is the replacement sensor = £49+vat...but it only fits certain airmass meters.
Nice one Sparks, any pics of these sensors by any chance? That number I obtained earlier is obviously incorrect... Looks like I will have to pull it apart when I have the chance as I don't know which year my car falls under, I have a feeling it's the latter
why is it you think its needing replaced ?

Basically it's been running like a bag of crap for the past few months, not at all acting like a 2.5L as it should. It has felt sluggish for a while now but recently it has slowly gotten worse. Tonight I was out in it and it was running ok, then suddenly, whilst in 4th gear going along, the engine slowed down and the throttle was doing feck all! I pulled over, as it was literally coming to a halt and the idle was all over the place, popped the bonnet and unplugged the air mass meter, at this point the idle speed stopped being lumpy and perked up. I think by default when you remove the plug from the air mass meter, the mixture richens up and makes everything that little bit better, albeit that the throttle response isn't as sharp.
So it seems that something controlling the AFR's is at fault, which, after pulling the plug on the air mass meter, seems to point towards this being the problem. I have ordered a new lamda probe which should also ease my mind, but I desperatly need a new or as new air mass meter, unless I can clean my existing one? Is that possible do you think? Or am I clutching at straws here?
Just thought I would add that I found a place on eBay that sells brand new MAF's for different vehicles and at a good price http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=250320433641 they might not be a genuine Bosch or Siemens item but as long as it sorts my problem out I don't care!
