Maf sensor

[Graeme 1978]

Hi all has anyone fixed a problem that will not go away on diagnostics.
The code ave got is P010106
And what icarsoft is saying is MAF air sensor 1 has a malfunction or a algorithm.
What started this was a intercooler hose had split it was the black 1 NOT the1 red 1 so a changed the hose still no good changed the MAF sensor still no good am stuck now.
Obviously it's an electrical fault not a mechanical fault any help will be much appreciated thanks.
This is on a w212 e class 2012 plate 651 engine.
Cheers

Hi Graeme, where did you buy the MAF ?

Did you clear the code.

I had a funny issue with my W220 recently. I decided to change the air filter as MB interval is too long in my opinion (and ot was filthy). After replacing the filter the car would be very lumpy at standstill (like a misfire or mount) bit fine with accelerator down.
My icarsoft said MAF, I was not having it. After doing some googling its not uncommon as the MAF is now dealing with fresh air and car thinks its running too lean.
I cleared the code and the car gradually
got better and is now fine.

So could be something similar, can is confused since you replaced the offending pipe.

clear codes and see if settles down. is the car running ok?

Thanks for the reply the new MAF was bought from ECP as mercedes wanted £218 for a refurbished unit.
A have cleared the codes a number of times lost count just will not clear also a forgot to mention that the car will not accelerate more than 3000 revs

Mercs dont like aftermarket electrical items and ECP are known for selling some junk

Ye a will agree but it comes down to £ to what a can afford this is a working car which needs to be back on the road asap cheers

Another Update
Went to work but it didn't last long new fault.
P227906
A leak was detected in the air intake system.
There was an algorithm fault.
Any help or advice on were to start looking for the leak would be good cheers.

If you’ve checked the boost hoses then the next most common is the intake manifold. A smoke test is the best course of action for these.

Case study - OM651 turbo fault

I don't often have time for this sort of thing, but I'm away to the Lake District on Friday, so have run the work down at the shop this week. I have had an entertaining one Monday/Tuesday so thought I'd share it... The car came from a mechanic up the road. He's pretty good normally, but just...

I’ve heard people have had success using those overly smoky vapes, but I’ve not tried myself

UPDATE
Phoned a MB specialist talked to him and he said to remove the ECP MAF sensor so a did and the car runs spot on now so obviously there was nothing wrong with mine but a did take the car to him and he put it on star diagnostics to clarify that mine was ok but he said the problems am having with me car before he said it could be a broken inlet manifold bolt but for now am just running it until it stops.
Cheers for the replys

If 100% no boost leaks, re-adapt maf sensor values (which will now all be out of spec from driving it with a boost leak).

if there are still boost leaks, fix them first then re-adapt maf

Also... bin the ECP MAF and buy a genuine OEM Mercedes MAF from Grangemouth Mercedes, it wont be as much as you think.
Aftermarket MAF's are a total waste of money, most come from china and are dogsh*t.
Just my opinion fwiw.

 

[Graeme 1978]

Ye a did took it back got money back and a put my original 1 back on got tested there was nothing wrong with it in the first place a only changed it because my icarsoft said there was a problem with it.
