I'm shopping for a new MAF sensor for my 1999 SLK R170 - I can get a Bosch one for about £150 or they have "copies" on Ebay for about £35 !! are they any good - anyone tried one ?

Thanks
Steve

Yup, Bosch. The ebay ones are (based on the one I bought for my CLK a few years ago) garbage.

Try these people.

www.airmassmeters.com

Used before, they were cheapest and was a genuine Bosch part.

I had good luck with an ebay one on my W140. Worth a risk for saving a couple of hundred quid and served me well.

Thanks for the replies - I must admit I am tempted by the ebay one £35 against £150 maybe worth a punt ?

Still not 100% certain its the MAF - it runs OK until you floor it for a quick getaway for example and the revs hit about 4K and it just hits a flat spot and dies - it doesnt stall just have to let the engine get its breath back and away it goes
If I rev it when stationary it hits 4K and does the same as if its hitting a rev limiter - does this sound like the MAF's gone?

Cheers

What happens if you run it with the MAF disconnected? I 'think' the car will goto a default safe map in this case at the expense of fuel economy, but if this fixes the problem it is your MAF.

At standstill there is a 4k rev limit, is the cut off whilst driving dead on 4k and in the same manner, soft and feathery or hard and sharp?

Yes, that sounds like a bad MAF. If you're unsure why not risk a £35 Ebay one? Same cost as quarter of a tank on a 140!

Sounds like MAF.
Had the same issue on my 1998 CLK 230K
I got a genuine BOSCH on ebay.de for a bit less that 150 quid.
Don't get the 35 quid ones, they last so much less.

Best of luck!
