Autobox wont change gear on CL - HELP!

[aka$h]

Hi Akash,
I hear what you are saying, but MB aint always right. What they tend to do is replace everything. For example if your electric seat stops working they wont mess about finding out what is wrong and which component needs replacing they will replace everything.
Thing is yes it resolves the issue but they charge you for everything including £100 p/h labour....
I think its give and take and dependent on problem.... MB want the car in and out asap...

Raj

I understand your point but my expirence with my w220 tells me otherwise. Ive had most of my cars worked on by independents, but the S-class sat at a garage in Northlondon for a total of 11 weeks and then at a indy in south london for another 5 weeks and they resolved nothing, in fact they were swaping bits with other cars to fault find. I had a bill in total which was more than double what mercedes charged in the end.

MB dont just change panels, the part changed was ~£250, they throughly tested other components and found the fault. If they had changed parts that were not required you have MB head office to take the issue up wth.

By all means take it to an indy but at the first sign of guess work, leave, thats my Honest advice, the 200/215 has a very complex electrical system.

I think your talking a lot of sense, I have read numerous threads about specialists chasing shadows, spending lots of time, and money trying to resolve what to them was a very complex issue. When the vehicle finally gets taken to a dealer the problem usually gets sorted. Some folks are simply 'stealer' indoctrinated.

Now before I get flamed, barbecued, and quartered there are some excellent, highly trained, dedicated specialist out there, hopefully the one dealing with this vehicle is one such expert and will resolve this issue in two shakes of a lambs tail.

My concern is this car has a history. Why did the previous owner not get this vehicle fixed?

Why put it in an auction? (we know the answer)

Why not get it fixed and sell it on with a clear conscious?

I'm sure the previous owner gave you a story, but my money is on just that, it was a story.

If this burnt\damaged loom called talk then I fear it might have a very interesting tale to tell.

Being a dealer I take my hat off to you for getting this problem resolved, I should hate to think it would simply go back into the auction sales only for some other soul to land up with this problem.

Well done,
Regards,
John

Hi All,

Thanks for the advice so far.

I took the CL to Santok yesterday in coventry. he couldnt get his hands on a star system but his diagnostic tool is very good anyway.
It shows the rear left wheel speed sensor to be faulty.

i replaced this at 7pm last night. When reconecting the wiring to it, i noticed that the wires were very tense to the point that they could have been streched when someone had taken the carpets out previously. (the wire runs from under the back seat squab up to the fuse box under the bonnet where it plugs into a control unit).

Anyway, i decided that before i take the car back to have the fault cleared i would replace this wire as this could have been the cause - not the sensor itself. So i replaced the wiring from the plug up to the front footwell.

However, whilst lying in bed i had a thought. The replacement wire that i used is slightly thicker in diamter than the old one, would this have any impact? I know these systems work to milliamps and would the difference in resistance cause an issue? have i made the problem worse!!? Should i remove the seat, remove the carpets and start again with the same diameter wire or will it be ok?

Anyway, im going to take the car back to santok today hopefully to get the codes cleared and see what happens. Im not sure if the codes actually do need to be cleared after replacing this part. Im not holding much hope at the moment that the problem is resolved, but at least we are getting closer.

Good Luck.

Its only a hall effect switch and milli amps. Pity that you did not live nearer liverpool the Frank Massy diagnosis center is there.

Looking on a brighter note there are some people much worse off than you, at least its not a CLK with roof problems or water in the boot.

I feel that you will solve the issues with this car, without spending too much,.
If you want any more print outs just ask.

Hi All,

Ok now the test shows a faulty speed sensor located at the gearbox. Specialist seems to think these were a common warranty replacement as they leaked at the seals.
Im not keen on spending £200 on that and then finding some other fault code so have left the car with them to look into properly...

Its getting frustrating now...

I can understand how you feel, what you have to be careful of is non plauseable fault codes going around the CAN bus..

This is what Rajinder had, 30 to 40 faults comming up, and everything other than the real fault came up, a break in the Can bus will show up faults all around the real fault.

I am going to have a further look around tonight. Chin up.

Jay,
As malcolm says, my faults where showing everything But the actual fault its self.... and as Akash has said with the idi it goes on guess work most of the time. If i was you i used a guy from MB and he was the one who found the root cause of my problem PM me and i will give you his number.
With electrics its a real nightmare, and as i said previously i had garages turning me away certain big indis in b'ham didnt want to touch it...

I am dealing with another thread on a CLK where some orange juice was spilled into the gear shift. That car is stuck in 2nd.

Malcolm

 

[jaymanek]

Rajinder, was yours exactly the same issue or was it intermittent?

Craig at Santoks thinks he can get it onto a star system one way or another so have left him to it... im just hoping he can sort it out soon.

well im not sure if mines in first or second, its doing 3.5K revs at around 40... but then its a V12!

 

[bolide]

Whether or not you end up putting it back in the auction you'll learn a hell of a lot. The only question is whether it'll be an expensive lesson

Have you looked into buying a Star system? I did but Mercedes said up front that they're of little to no use with W124s

Mine was intermittent, it happened every now and then - it started to get worse, but would go into limp mode whilst driving.....

it really needsto go on star, when you call ritchi he will get a hold of star machine when he looks at it if you tell him...

Hi Jay,
Any news?

Well Craig at the specialist says he put it on the mercedes star and it is showing the same fault, i.e speed sensor at gearbox. He seems to be confident but im not so!

The part is ordered at £130 odd plus fitting.... hopefully will have some news before next week....

I thought that it would have been possible to cold check it on the car or if it has been talen off

If he is confident then hopefully there will be no charge if it fails to fix the fault. The part he replaced is either defective or ir isn't.

Good luck,

the thing with electrical faults is they are a pain to figure out at the best of times. As mentioned before my star diagnostics were showing all sorts of problems none of which were related to the main cause.

Its hit and hope majority of the tie with electrics, Star only points in a direction it doesnt pin point it.

[jaymanek]

hmm, but this is a guy who was head technician at mercedes and is using the mercedes tools, so surely this is my best option? Taking it to mercedes should make no difference apart from to my wallet?

If I were you I might consider having an open mind on that question. You appear determined to believe that statement so it will be difficult to disagree with you.

If this independant is as good as you say, then stick with him. In my previous post I asked if he will charge for the part if it doesn't resolve the issue. I would not be very happy if I paid out good money and the problem was not resolved.
