NEW MAF for £30 gave me ABSOLUTELY AMAZING REULTS...5 minutes to fit

[W210 Fan]

Yeah , we watched the MAS faulting on my dads 430 on Ollys star machine .

ah, its crank sensors that dont, I know the symptons of a buggered MAF anyway and my CLK has them all!!!! stops me driving it like an idiot so may leave it anyway,

 

[Howard]

Will put the fuel consumption up ....

Try a PM to Nick_mercedes , he may have one .... we got one for the 430 off him good price too ...

Actually they dont generally leave fault codes on petrol MB engines; just codes that are a consequence of that fault such as "self adaption at limit value".

It is taking the codes and deciphering them to what the fault actually is which is the skill.

Infact I would say 10% of fault codes are inaccurate as a code. For example an EGR fault code could mean all sorts of things, not just a faulty EGR. What do some garages do? Bung on an EGR vale and hope.

So there. Lol

 

[Howard]

I stand corrected , what was it we were watching then Olly ?

Cos you said ' There , thats the MAS , you need a new one ' .... we bunged one on and its perfect now.

Ahh that's "actual values".

That is engine running data that cam be looked at to see if there are any components not quite in spec.

 

[lynall]

I remember my last car looking at the actual values whilst driving it as occasionally it would chuck up a fault and as i had chipped the car it basically couldnt measure the air flow beyond a certain point, ie it ran out of range, cure ignore it!

I'm not always anti non Bosch/MB - but for a part that should last 10 years or more, I don't mind paying £150 - rather than £30 every year.

'cept original factory fitted MAFs seem to come up as problematic with remarkable frequency on cars that are well well under 10 years

If original parts (Bosch? MB?) lasted 10 years I wouldn't have a clue as to what a MAF was and there wouldn't be the "It's the MAF" knee jerk advice whenever anybody reports an engine problem.

I think you did well, you couldn,t get any help to suss the fault so you took a flyer and bought a part cheaply on e-bay which has transformed the car. Even it it fails after a few months and the same symptons return you can always buy with confidence the 'real thing' knowing it will fix the faults. well done

I must have just been lucky then This is my second 'old' merc (10 years old now this one), and its the first time I've ever had to replace one...

Out of curiosity then, would would you all here say was the average lifespan of a genuine MAF? (So I should expect when the current one will need replacing again!)

The don't make them like they used to

Don't know. They seem to quite happily start failing on cars from around 3 to 4 years old. There's certainly enough traffic of the forums where MAF comes up as the likely cuplrit. IMHO it's become a badge of honour that you haven't owned a modern MB unless you or someone close to you has had a MAF problem.

 

[MercFanUk]

Excellent, I get to wear my badge proud now then

 

[Birdman]

Had my MAF replaced earlier in the year and there was no fault code listed but the engine was completely transformed. The original part had lasted seven years (like my battery, which expired last month).

Problem is, just can't get the regular 30mpg on a run anymore like I used to, even driving like an old gent.

Thanks to everyone.
It has answered the question of non OEM parts versus OEM parts as far as sensitive devices such as the MAF go.
I replaced my MAF six months ago after it was diagnosed as faulty at the local indie, and for convenience went half a mile up the road to GSF who only had non OEM in stock, but to be fair, advised me to let them order the original Bosch.
Being impatient I bought and fitted the MAF for £60 and was totally happy, the car responded like new, until the last couple of weeks where the little problems are coming back.
A visit to the local indie and wired back up to the diagnostics revealed,
MAF.
Am going to get the original Bosch MAF and fit, will let you know the results.

The Ebay MAS might work ok , but you will find an OEM one will work even better.[/quote]

not true

just to let you know,the ebay seller is my mate ( he live's in wigan also ),
i nearly went to china with him last year to set this deal up,they are made in the same chinese factory as the orginals,from the same materials on the same production line,and he is the sole importer.so you have nothing to fear

 

[Howard]

Wow ...

Be interested to see some hard evidence to back this up

Would negate ever having to buy a real one again ...

I realise Bosch are bound to say this , but :-

[Dieselman]

I too would be interested to see the measured airflow outputs for Bosch V's the aftermarket ones.

Are different ones available, if so I would be interested to see output curves..

I have a plan..

And I concur!

 

[andyshore]

Can you really trust imported copies of spares after you have read
the Bosch comments?

 

[miro]

Absolutely astonished with the improvement, car has never felt so good. feels like I have added 100hp and 10x to the response time.

I'd been having major probs, intermittent at first but getting more & more constant with my 99 clk 320, 110k miles;

**sluggish starts in first, especially after starting the engine'
**lumpy' acceleration, - sometimes giving the sensation of a blocked tube taking a second or two to clear before revs responded
**power loss when flooring it - revs just falling away then not responding
**rev surges when putting foot down but no response in acceleration
**trying to accelerate only for revs to drop down to and get capped at 2k
**having to pull over and restart to fix..or limp along until it cleared

Today fitted a new MAF off ebay for £30 delivered...result is astonishing:

ALL above problems completely GONE

Amazing how much influence the MAF seems to have on the transmission.

Thought I would share...as may be able to help people with similar symptons & also save them money on the part and labour as it seems that the cheapo non mb Bosch part (which would have cost 150 + labour) works just fine...& is very simple to fit.

The transmission works on Torque. If the engine is not behaving well it will give wrong information to the transmission.

 

[andyshore]

New Bosch MAF fitted and the car is performing better than I could ever had anticipated.
No comparison whatsoever with what I thought was a normal running CLK320 after buying the copy part, and it didnt cost much more to achieve these amazing results.
