Title: Maf sensor were to buy?
Post by: Jayy26 on January 14, 2014, 09:19:00 pm
Im going to look at a car from the forum at the weekend but he's just said the engine management light is on and he says it's the mad sensor..

Does anybody know we're to but one a decent price or have one laying around for a price?

Or do you think I could just clean it?

Also I have a old mk4 gti maf sensor in my garage I'm guessing they will be a lot off difference?

Cheers

same as above.

How do you know that MAF is not reading correctly? did you log the car to see what it reads? Get fault codes first before you start messing with sensors.

If it is where can I buy it

Without a scan for the stored fault codes no-one can really help you.
As a general rule if the maf is bad/faulty the car should run better if it's disconnected.

He said he had it plugged into a diagnostic machine at his mates work..

And I was thinking about disconnecting it..but going to be gutting on the 3:30 drive back :( and it should be running 270bhp :( lol

Only ever buy GENUINE MAFs either from a TRUSTED supplier or VW themselves.

What you counting as genuine ones..bosche?

There's some on eurocarparts for £35 has anybody used one off these?

He said the car runs faultlessly and if it wasn't for the light coming on you would know ..
So I asked if it was fueling right because trying to figure what the problem is..and he replied with Im guessing maf is over-riden when faulty and car relies on map and lambda to control fuelling.

Is this true or ?

I think you're sleep walking into getting this car if the owner isn't going to sort it out before you accept it. The issue could potentially be more costly than just the cost a maf replacement. 
btw a genuine new VW maf costs around £120

Technically the are genuine because there branded....I can't seem to justify spending £70 more when there a bit off plastic I'm guessing there's that much off difference then..I think he is gonna negotiate it in the price and says it runs fine..he's of this forum the black gti

Would it not be prudent to get the owner to sort it before you buy? I think it would give you more confidence when buying.

Yeah if your going to buy cheap keep the invoice as you'll need it to get replaced under warranty in the coming months.
That's fact, you get what you pay for.

Thanks for the 'constructive' comment unlike the others..it's not hard to be decent and you clarified what I asked...that they will most likely fail being cheap

Okay sorry for being harsh.
But this happens a lot and it annoys me

People ask for advice - Eg what maf do I buy
People give advice - buy a genuine one
People who originally asked for advice - i'm going to buy a non genuine maf.

Makes me wonder some of us bother. Any electrical or suspension component, bush etc, all needs to be genuine.
Mafs are VITAL to the correct running of the engine. I've SEEN first hand "new" non genuine mafs that are faulty, new "non faulty" MAFS that make the car run WORSE than the faulty genuine part..

Through work we get the odd customer who won't buy a genuine sensor whether that a MAF or MAP sensor and end up buying cheap usually from Europarts 8/10 of these sensors fail again within 3/4 months.
Costing more in the long run to get the car diagnosed again and the inconvenience of the car being in the garage again.
Genuine is expensive but it's for a reason.
If you were trading a car in or not keeping the car then cheapest is fine but you do get what you pay for.
