2010 w212 estate boot

[usernamerequired]

Had a problem with the tailgate today. Difficult to see what the problem was as it was my other half there not me. Boot wouldn't close. Made it down but kept popping back up. Making the warning sound. Will try to attach video. Anyway she's given it a helping hand once it got to the bottom incase it was the latch not engaging. Something has made a bang and now the auto boot function isn't working at all. I believe she now can open and shut it manually which at least means it's usable. Any idea if we've made the problem worse and what the likely fault is. We are covered by the mb assist I suppose she should of called them?

Any ideas. Motor is still whuring away when the buttons pressed but nothing happening. It's like the motors still working but whatever is between this and the door is broken?

Not sure what's going on with the tailgate. But you could take the negative lead off the battery for a minute or two and it might reset the closing functionality.

Whe I fitted the boot liner the other day. The liner was just catching the tailgate ever so slightly. I had to bend the edges of the mat inwards and away from the tailgate bottom. Is there something lodged on the runners or bottom lock of the tailgate.

Mine won’t close if the boot floor isn’t properly seated. Whenever I lift the floor, to get to the storage below or the spare wheel well, it takes a bit of a whack to get the floor completely flat again.

Thanks for the replies. Unfortunately I think something has broken when she's helped it to try and close. There was a bang and the tailgate doesn't move up or down now. The motor still makes the noise but I suspect whatever connects it to the tailgate has broken.

I rang a couple of local mb specialists. 1 won't touch if new motor as he's a 1 man band and head lining needs to come out. The other are just in process of doing this to another apparently. 250 for a motor from breakers and 250 labour. Will the lining come off OK or would I regret getting this done?

I found this thread online on another forum. Describes my problem exactly. Don't think I'm brave enough to diy though! Any advice?

I'd definitely DIY that!
That DIY guide linked to in the other forum is very good.

It's not particularly skilled, and you taking your time might result in a better outcome than a garage 'trying to work to a clock'. I.e. less smashing and better care and fit when refitting.

The worst thing is, it's blooming freezing out there, which means trim and clips are going to be non-compliant, and brittle. Which means breakages.

My advice would be, if you can, wait until warmer weather. I'm not clear if you can still use the tailgate, of if it's totally broken.

If you can't wait, do it in the daylight and use a hair dryer on all the trim before and as you are removing and reattaching it.

Yeh I've not watched the videos properly but maybe I might try. I do have a trade so am not completely un practical however me and motors usually don't mix. I think that guy was in the states. Do you think if I go down to Mercedes local parts dept they will sort me out the bits?

 

[MrGreedy]

You will find Merc dealer prices for parts vary wildly.

E.g. my local Midlands Merc dealer has recently sold me coolant hoses, trim clips, orange turbo seals and a power steering reservoir at very, very competitive prices. Jaw droppingly low in some cases.

But were highly uncompetitive on power steering reservoir, wheel arch liner and rear level sensor, so I went to Mercedes Edinburgh via their eBay store.

So if you find any random items listed by Merc Edinburgh (or Newcastle), they do have a direct phone number in the ebay page, and you can call them up, they will take your Reg, and talk through with you which part numbers exactly you will need. It would be worth mentioning the part numbers listed in that DIY post as I doubt they are different, but best to check either via your local dealer, or via Merc Edinburgh or Newcastle dealer on eBay.

 

[usernamerequired]

Yeh I will contact local dealer firstly.
One of the garages I went to today have got an 11 plate booked in for the same job in February. So my plan was to wait till after then anyway, let them make mistakes and learn on that one first. I can use the boot manually for the time being so if diy will wait till warmer months as you reccomend.

One snag which caused the breakage was the door refusing to latch. It was making the alarm noise when close to bottom and coming back up. Will be annoying if I fix the motor but then have that problem to deal with. Even now if I press the button you can hear the motor do it's cycle but nothing happen. You hear it trying to shut, then a beep then it trying to come back up. I will have to diagnose why this is happening also. Any idea if sensor can be dirty? Sounds like poster on other thread had same problem but no mention of sensors

 

[usernamerequired]

Just re reading that guys post including the original message. He mentions the ball stud on the motor side of the assembly is broken. Is there a way to remove the covers to check where mine is broken. I'm assuming the sake job needs to be done but is it not worth me checking if it is a different part which is broken which can be changed without all the trim off

Just been into MB Automotive, independent Merc specialists, and they were in there trying to figure out how to reinstall the motor on an estate, but I didn't clock which type (but I recognised the part from looking at images of the motor from the and the linked DIY guide).
I was chatting with them about it, and they also mention there is a technical update for a revised part. It looked like it related to the ball stud.
So maybe you can get away without a new motor. Worth looking into this is a bit more detail, as new motors from Merc are daylight robbery. Literally the same price as you can buy an actual car for.

I think I phoned them today and spoke to someone. Are they in Loughborough?

Yes. You would have spoken to Martin who staffs front of house and does the customer bit.
They're a good bunch. I've tried loads of Merc and 'German' independent specialists in the east midlands, and in my view they are the best.
Very reasonably priced also. I mentioned on another thread I've just paid £224 for a transmission service inc. TC drain down (plus another £69 for a rusting ATF sump pan )

Just to note, in that linked DIY guide, the part number they list is A2048203042, which is the latest part number.
It's quite possible you have one of the earlier revisions. Unusual for three revisions of this part I would have thought.
Maybe the technical bulletin relates to a possible 'upgrade' to effectively make one of the older motors into a newer part number equivalent.

If anyone reading has access to the TSB system, any insight would be appreciated I think.
