Mass Air Flow sensor. Part exchange option only?

[Dico]

I'm looking for a MAF sensor for my VW 1.9TDI. I'm not entirely sure it is the MAF that has failed tho so don't really want to part ex mine.
The dealers want £90+vat part ex or £274 without part ex!. GSF car spares want £60+vat with part ex, or £25 surcharge til a replacement is returned, but the chap couldn't guarantee it was an original item or not.
Suggestions where I can get a quality item at a decent price, preferably without part ex if poss please.

Thanks in advance :esm

Well, you have a price from a dealer there, and also a price from the leading parts supplier. If you want to guarantee OEM, you need to buy from the dealer, but GSF is a big company and likely to not be in to business of buying poor stuff.

[MattYorke]

A quick google firmly disagrees with gsf being good quality.
That said, i've never had an issue personally with any items I've bought from em.

I always complain when I have a problem, I rarely praise when I don't. GSF are a large company, and they are going to do some stuff wrong, and get some dodgy parts from time to time, but I bet if you google VW, they are going to have a fair few complaints about service and quality too. Swings and roundabouts really.

As a matter of interest Ive been looking closely at the cheap Chinese replica Bosch AFM,s used on the Range Rover and they are pretty poor. The output is unstable and alters with engine bay temp, so if its from the Far East Id give it a miss.

I got my Bosch MAF from here:

Quick service and saved being charged another £250 on top from a main dealer, same part different box.

Euro car parts sell the factory re-man genuine Bosch ones for around £70 exchange of course

Find out the make of your unit.VW dont make it and I`ll bet its a Bosch unit.Euro will supply the same part a lot less than VW.I needed one for my Merc and Euro supplied the same Bosch unit with the same Bosch part number in a Bosch box at half the price of the same part in a Mercedes Box,and no part exchange.This happens all the time with most parts with almost every manufacturer.

Thanks for the replies.

Euro car parts sound favourite, but they don't list the MAF for my Passat. Strange as its a part that regularly fails. I'll give them a ring in the morning.

Out of interest does anyone know if the pressure sensor could possibly cause my boost problems? I currently have zero boost.

Ring them they def do them I have changed enough of them through failure nice easy fix and easy to diagnosis don't let them talk you into the white box brand(cheaper un-branded crap)though total waste of time you want the Bosch re-manufactured jobbie last one I got was for an Audi and that came from the main dealer(still exchange)at a knock down price may be worth ringing round

As said, ring them. Their website is shash. To make sure you get the right unit, get the VAG or Bosch part number from your original unit. They have the system to cross reference these numbers, as Bosch have probably since superceeded the number.

[Dico]

Well I replaced the MAF probe (Eberspacher)on my B5 tdi which made no difference.

I have EXACTLY the same issues as this chap- http://www.ilexa.co.uk/forum/index.php?topic=1393....
A mechanic then did a scan which showed up that the fuel cut off valve (N109) was faulty, but the mechanic said it would be unusual for the car to run at all. I've since Googled it and came up with the above link.
Anyone else ever have this problem? The relay is around £30 so I may pay a visit to the breakers unless someone has a link to a cheaper one?
Cheers.

You should have unplugged the MAF in the 1st place if you get a slight improvement of power (not full power) then it's the MAF,with MAF failure the ECU go's into limp mode no Turbo boost out of interest the early Snap On scanners did not detect this fault

[Mr2Mike]

Have you checked the obvious stuff like the vacuum hoses and boost control solenoid? If you have a VNG turbo rather than one with a wastegate then these are quite prone to getting stuck giving zero boost.

[Dico]

Checked all vacum hoses. All in very good nick. I'm not sure which turbo mine has but I couldn't see a wastegate. Removed and checked the EGR.
Just phoned my local VW dealer but they don't have a 109 relay listed for my chassis number! More Googling.

[Dico]

I've narrowed it down (I think!)to the 219 relay. Ordered one from VW and collect tomorrow. If this still doesn't resolve the lack of power then its off to a mechanic.
The 219 is a contact relay and supposedly shouldn't go wrong as often as the circuit board type, but it does. I removed it yesterday and pulled it apart. All three contacts seemed clean. When I put it back in position the glow plug dash light magicaly reappeared, so it does have some kind of fault.
Fingers crossed.

Why not get one from a breakers yard? £20 and no need to return an old unit.

And no guarantee the one you get isn't as bad or worse than the one your are replacing...
