C43 AMG Only running 235 HP

[porterada]

Just had a look at the old one and the bosch part number on it is 280 217 515 but the replacement bosch on i got from euro car parts has the part number of 280 217 810 so i am guessing that's why i am getting issues with the new one even though it looks exactly the same

That's the wrong maf

Take a look at this link, use the drop down menus and it appears BOSCH 280 217 810 is the correct MAF for a C43 (looks like Euros did get it right).

It does look like its right. So that opens up many questions. Does the ecu need to re learn. I know in the old subarus you could reset the ecu back to learning mode. And if that is the correct one. Why was an incorrect one on there in the first place. :'(

 

[bigasotonuk]

It appears the MAF fitted to your car at the moment is from a W203 C240, if you select a 203 c240 in the drop down boxes also googling your original MAF pt no brings up e-bay auctions for it stating W203 C240.

If any engine learning adaptation is required at all 10-20 minutes of driving will have it sorted but if this was the issue I would of thought you would noticed almost immediately.
To be honest it does surprise me that a MAF from a 240 engine would even fit as I would of thought it would be narrower.
Thinking about it the gearbox ECU may have learnt and expect lower engine power values, driving it hard away from the lights and a bit of spirited driving MAY help.
Something worth mentioning is the fact that another 43 I know was unable to be rolling road tested as the ESP system was turning the power down, mine was ok but I do have an issue with implausible speed signal, I,m wondering if your power was down because the ESP was limiting the power, though to be honest I would expect this to be picked up by the rolling road operator

A "bootstrap" of the ecu will reset the adaptations and make the ecu ready for a new MAF. alternatively, driving it will make the ecu adapt to the new unit over time. If it has had the wrong MAF on it I don't know how long it will take, but take it for a run involving some steady speed on a dual carriageway and see what happens.

Ok so took everything off to make sure i had not pinched a vacuum pipes or something when i replaced it on Friday. Put it back and drove it for long periods on Saturday and Sunday. Idling is now fine but still down on power and its now doing a very weird change from 1st to 2nd when on full throttle. Its like it needs to attempts to shift up. I may upload a vid but think i am just going to leave it as is as i have now almost spent what i paid for it getting it showroom fresh and don't have the heart to sink more money at the moment

Just an update for any one that still interested, Car is going into Star in reading for a ECU reset. they also found that the gearbox had way too much fluid in it, so they are going to take some out. This is after i had all the work done at MB main dealer in slough ( i recommend no one takes their car there), as i also caught them speeding in my car after they did the tranny oil change Thank god for the tracker i fitted. So as i have been driving the car for a few months like this i do not know how much or what damage has been done. SO hopefully i can build up a good relationship and trust with star as i will be not taking my car to any MB main dealer again after all this

Star Motor Services Reading

I am sorry for the delay in response to this i was actually on here today to start a new thread about a very Bad Experience using STAR Motor Services In Reading But Will add to this old one.
over the last few months the car i still think has not been running as quick as it should be but i decided that its getting on a bit and i love the car, so i did not want to keep running it on a rolling road and put the lower output down to the age of the car and the 109 k that is on the engine.

But now to my main point. over a year i go i made the decision not to take my car to MB in slough as i caught them twice taking my car for road test's (under Load) no doubt. So decided to try and find an independent Mercedes Garage where i could take my car for the works that i either did not have time or the specialist tools to do, And also to keep the service book up to date. So last Friday the car was booked in for a A service with Oil, Spark Plugs Drive belt that I provided also i had provided both inner and outer anti roll bushes as on rutted roads you can hear the odd knock i informed the guy that if they had time and if after inspection they needed replacing please do it. the car was dropped down at just after 9 am and i headed off to reading Town Center where i would wait. As i have probably mentioned before i have a 'track your' tracker fitted to my car, I come from a family of mechanics of various levels and know what used to go on especially at Mercedes in Slough, so fitted it for piece of mind. at round midday i headed back to star and was told that there was still and Hour or so's work to do on the car. (which is fair enough they had other things going on etc) but was still left wondering how 16 spark plugs, a belt and an oil and filter change would take 5 hours. So i headed back off to reading for a pint. It was after about 30 minutes my phone pinged and i saw my car was on the Move. Now for me the only time a car should be road tested is when the customer has a specific issue at a certain speed or road condition. So i started heading back as i wanted to see visually where they were taking it and why. As it turns out by the time i got back the car had finished its 'road test' as was actually parked up round the corner at one of this drive in valeting places. I waited around and this was when the first major horror happened. The guy who had cleaned it, got in and tried to start the car, which failed twice ( never had any issues with starting the car since i had it) it was then he must have started it with his foot on the floor of the accelerator pedal, as it started and then immediately hit the in park rev limiter, ( thank god Mercedes put that function in) he then proceeded to tear off up the road to return the car back to Star, he then walked back to his valeting place (so Star let non Star employees drive customers cars!!!) i have recorded a bit of this drive back but could not get it all as i was trying to unlock my phone. I walked the little way back to star to be told that my car was ready, But they could not do the drive belt and the Anti Roll bar bushes did not require replacing. When i asked why the car had been on a road test all i got back was ' we road test all the cars'.
So now i am thinking you have had my car since 9 am and its now 1 pm and all you have done is change the oil and the plugs. Now my tracker had a speed alert which was not breached thankfully, but that does not mean some little OIK did not spend a few minutes having some fun in a customers car.
As you can imagine at the point of paying i was to say the least a little mad, so rather than ending up in a police cell that evening i just wanted to get away.

and that brings me now to some new things i have noticed now on my car. first is there is an alarming grinding noise when on full right lock from the off side front, (never there before) also now on cold start there is a very Noticeable knocking sound for a while like you would get from a tappet or lifer.
Also i was informed by star that my rear tires would be due for change in a couple of thousand miles, Which leads me to think some one had a bit of fun, as i had the fronts replaced 2 weeks ago and was told that there was 6mm left on the rear so they would be good for at least 6 months or so. Weird No??

So, Why did it take over 5 hours to do a simple oil and plug change?
Why are people who don't work for star allowed to drive customers cars and rev the from start... Why does it look like some one has taken a hammer and chisel to my fan Drive Nut?? Why are customers cars taken to a dead end road, ( i will attach a screen shot showing the location for anyone else who might be thinking of taking their car there.

I guess this all proves that there are still no decent Garages out there so i will have to forgo the want of having a dealer or indi stamp in the book each year and do any work/ repairs myself as at least i know the work will be done and nothing else broken in the process.

I am now thinking if it is possible to get the ecu interrogated to see if the ESP system was turned off last friday at any point.

There are some superb ones out there and they will bend over backwards to help ! You have just not been lucky enough to find them..
MBS and Prestige Car Services, both merc and both receive nothing but praise on this forum for doing the impossible..
I can comment on these two having used them both and sending many other people to them with happy results..
they are portsmouth, southampton area though, so not good is you are far away

 

[porterada]

Well at least there are some good ones left i guess, I just cannot believe that these people think that with all the things in the papers about the Main dealers taking peoples cars for speed runs, Seem to remember A ford MD down south recently in the paper that customers would not be interested in what happens to the car while in their possession .

I work in I.T. but have a good mechanical back ground and it would be like me taking in a users laptop in to be fixed and dragging it round on the floor all day, putting virus's on it and then giving it back to them saying, well i have done a bit of what you want and cleaned it so there you go.....

Just makes me so mad these places can get away with it. If only had access to a 2 pillar lift

 

[star]

I am sorry you were disappointed in the service you received and I will post back on this when I have all the facts.

 

[WG M-B]

I personally think the guys post is disgraceful Ian.
It sounds almost premeditated and without any real substance or facts ( the bits about the lifters ticking/ grinding noise )
I'm sure Cole will be desperate to help him out :wink:

 

[Miffy]

how many miles did your car cover whilst in Ian's care? as it seems to me your claiming in that short period they have managed to create enough wear on your tyres to cause them to be worn out? Also bear in mind the tyre wear advise is subjective and is only based upon your driving style and conditions for the next few thousand miles. Personally I have never used Ian's services but would not hesitate to put him and his team forward as a respected Indy, based on the amount of good feedback he gets.

I think the most important issue here is, why on earth have you decided to make a public complaint before you have even discussed your feelings with Ian?

 

[porterada]

The reason why this was posted on here first is that i know the process,( i say i'm not happy, then get told to bring the car back, Like i am going to do that now...) Trust me i am crying out for a local garage who i can trust, the nearest family member with a garage is in Central London, But the car will be heading over to him this weekend for an inspection. Regardless of what i am finding now driving it. do you not all agree that letting some cleaning company drive the car??? i'm not going to repeat what i have said again but i do not consider the service i received anything like what should be expected

 

[Miffy]

But your not happy about a grinding sound, which could be a wheel bearing, do you really think they drove your car that hard that they have worn out your tyres and a wheel bearing?

You also complain it took 5 hours. Did they bill you for 5 hours or was it just on their premises for 5 hours. I think its quite normal to bring the car in early, and have the work completed as part of the normal working day, unless of course you had pre-agreed to pick the car up at 11am?
