Hi all, need help if possible.
I have just replaced the throttle cable and pedal assembly on my new to me ML500 2002 model.
Does anyone know the position on the pedal side, inside the vehicle, of the turn thread that sits behind the clip that goes through the cable inner to clip it to the pedal?
There is an adjuster there, which allows the pedal to sit further down, but then this would stop you getting full throttle, so there will be a happy place for it to be adjusted too.
I have re-taught the throttle position sensor, but this works only for a second, then when i take off, moments later, I have no throttle.
I seem to have a lot of inner cable, which maybe a badly made cable, mercedes are looking into this for me, as they suspect it could be wrong size!!!.
I have tried every setting on both ends of the cable to remove the slack, but when I do, the cable adjuster on the engine side is at the very end of its adjustment and almsot falling out, which tells me this is definitely wrong.
I would be able to post pics of what i mean and what I am up against if this helps.

I am stuck at present, and going on the assumption the throttle cable supplied by my mercedes dealership is the correct one.
If it is not the correct cable, then this answers all my troubles, but if it is correct, is there something i am doing wrong in the fitting and adjustment of both ends?

 

Why did you replace both components?

You should have visually approximated the distance of the inside pedal.

Other than that, here is the adjustment of the outside throttle cable #3 PDF.

 

Hi dundee, I had to replace both as the pedal was knackered, being cheap ABS plastic, the throttle pedal had about 2 inch of side movement, after being 18 years old. They are designed to wear out like this, as cheap to replace.
Thanks for your diagrams, they helped me know for certain the cable i got is wrong, even though it almost fits.

I have included images to show what I meant about the inner adjuster on the pedal side.
I have done everything by the book, but since I wrote this yesterday, MB dealer is sending me another cable out in the post as they phoned me this morning.
We suspect the cable I have fitted has being made wrong, as in ther inner is about 3" too long, so no way of ever taking up the slack.
This is why i got confused over the pedal postion inside.
No matter what way I tried to adjust the cable, it would never lose the slack, so could not get full throttle on the relay lever position sensor.
Will keep you updated when the other new cable arrives tomorrow.




I told them I want an original MB stamped one, NOT the cheap inferior crap I bought already from them, and paid top money for.
I was not impressed to find a main dealer selling third party parts as genuine.
I thought this was illegal?

 

If a dealer sold you a knock-off cable then you have a reason to demand your money back.

 

what's the cable part no please thanks.

 

Being that you have right hand drive, you will have to call or visit a M/B dealer.

 

Thank-you for that Maj. Dundee.
I suspected I had been had over.
The cable came in a sealed poly pouch with the part number on a sticker on the packet only, but nothing on the cable what-so-ever.
This is also happened with the very expensive auto-dimming drivers door mirror I bought from them.
It also is NOT a genuine Merceds part, but it fitted 100%, so I have just let this go.
I told them this is NOT the right cable and not even a genuine cable they have sold me, but a third party knock-off.
Lets say they were quick to try and put this right.
They Also said maybe the factory just got it wrong that made it.
They have ordered another cable and have paid postage there end to get the new one to me, but i still had to pay for the other new cable, then they will refund me when I return this knock-off one they dumped on me.

I can quite easily get loads of cheap knock-off parts globally for this vehicle, but for a main dealer to be selling on third party knock-off parts I find quite a serious issue to be honest, considering they are also charging the customers the full dealership price for said parts.
I may have a word with the actual owners who run this franchise, as the office of fair trading standards would not be pleased if I was to alert them, as this is serious and a blatant theft of peoples money, so this franchise can make more money and look good to the people above they answer too.

 

The cable i took off is an original Mercedes one.
Number on the original cable: 1633010623 02W08
See included image for cable and number I took off.

The one I bought from Mercedes dealer in Swansea has the number on the reciept and the packet i took it out off, but nothing on the cable, proving it was NOT made by Mercedes themselves.
The invoice number is:
MA163 301 06 23
So this first part number is almost the same, but the MA does not show as a Mercedes part number, or maybe I am wrong on this, as only a guess at present by me. The next part of numbers is missing totally. There is no Mercedes three point with circle, or M or anything on new cable, like the old one. no writing at all.


Genuine Mercedes throttle cable. The new one I got has nothing on it what-so-ever

 

That part # is valid, so just wait for them to provide you with the real cable. Open the package in front of them and check for the stamped part#.

 

I have since dragged every bag from my recycling and at least all 4 mudflaps are genuine Mercedes with the genuine stickers on every poly bag.



The throttle cable bag does not even have a sticker, all I have is a part number from the sales invoice, not even a throttle cable part number sticker on the bag.

I have so many bags this end of new bits, i must have got confused and thought I saw a sticker on the throttle bag, but I am mistaken. the throttle bag in front of me is void of anything what-so-ever.
The brackets, screws, rivets, and clips for the mudguards are not obviously stamped, but at least every bag says and displays country of origin under licence where the bits were made.

 

They have sent it out, so cannot open it in front of them.
In my other replies, you will see only the invoice shows me a part number, this is also true with the new mirror I bought from them.
Only my invoice shows the part number, but the mirror has printed stickers on the back, not etched by Merc like old mirror I just removed and used to get the part number for a new one from main dealer.
So this may also be a third party part sold to me at full dealership price.

 

I thank everyone here for your help and input.
It looks like I have managed to sort out this cable problem.
I have the replacement cable in front of me. It is in a sealed bag with a genuine mercedes sticker on it this time.
I can tell by simply looking it is looking correct as there is no 3" inner length on top of the 3" you need to attach the cable and adjust it.
Made under licence in France.
This MB M-Class I understand from what i have read so far was originally for the US market, so made and assembled and distributed in the US and sent globally from there. Invented to rival the BMW X5 and landrover range rover.
Australia gets the right hand drive ones, and some were shipped also to the UK and other right hand drive countries.
They are not and never were made or assemblied in Germany. this is why all parts are from anywhere in the world except the UK.
Will fit it when the rain stops this end as very severe rain and cold for the last two days.
I will also put up a couple of pics of the wrong cable against the right cable and then this thread hopefully will be finished and resolved.

 

Was easy to replace the cable second time round.
The images show the difference of each cable.
The longer cable is probably for a different year/model of the Mercedes as it is made the same way and exact same parts and method of crimping the finished cable. Someone, somewhere, ended up getting the first cable i bought into another bag and assumed it was for my year W163 model, which eventually sold, and I ended up with the darn thing.
This caused confusion my end as i could not understand why i could not take up the slack, unless I shortened the length of the foot pedal travel inside, which of course will also not work, as then you are still stuck with only half throttle from closed to open.
So all done now.
I moaned about fake or knock-off parts, but my moan was NOT correct. It looks like many companies make the parts globally for mercedes under licence, so the MB logo will not be on the item if only made under licence, but it is being sold as a genuine dealer specification item.

If the cable had been stamped with the part number, this would never have happened. But because a generic part made under licence had no markings, it was hard to know it was not the correct cable.

Removed old pedal, slowly and deliberately pulled on outer cable on engine bay side until white palstic sleeve came out of rubber grommet. Pushed through bicyle outer cable, through hole into engine bay.

Here I have the bicyle outer cable from the pedal side, to the engine side. I am going to attach the inner new cable to this and pull back through into the rubber grommet.

Make sure you us e a bit of force while wrapping round masking tape to hold them together as you are going to use quite a bit of force and pressure to mount it 100% in the rubber.

Once you have pulled through the outer bicyle cable, back into the pedal hole with the new cable attached, start to remove the masking tape.

Slowly and deliberately, use a circular motion to get the white outer casing of the new cable to line up and start to pull through into the rubber grommet and make sure it seats perfectly, not lop-sided, or squint. The rubber grommet is not difficult to replace or put back in if you dislodge it. It goes in from this pedal side only.

 

I will add the chunks of missing foam and soundmatting around the hole are not my doing in the last picture.
The vehicle is new to me, but 18 years old, so at some time, someone has done something weird to the deadening and soundproofing around the hole. The mind boggles as to why and who would need, or do, such a thing.

Also do not oil these cables, as they are designed to be fitted dry and stay dry inside. The inner braided wire is also plastic sealed, so cannot rust so easily.
The engine end has also a rubber grommet over where the cable comes out of the outer, so stops water, grit moving back down the inner cable also.
Oil will slowly run down into the cockpit and right onto the carpet and stain it for ever more.

My way of feeding cables works for many types of cable running into chassis and frames etc.where the channels can be hidden and blind.
many people know this method, but if not, this is something to remember.
