W221 back end dropped right down onto tyres

[Craiglxviii]

Right i have found a menu which states 158 left front level 10mm 161 right front level 3mm 164 rear level 127mm and 166 pressure at pressure sensor 0 bar. Does any of that help mate cause kooks to me that the pump is not working at all?

Pump has failed most likely; have you noticed poor response recently while driving?

With the engine on, locate the pump. There is a union that comes out of it with a line that leads to the ABC fluid reservoir- this is the pressure regulating valve. Try giving it a (VERY GENTLE!) tap with a soft faced mallet, it may open it.

Otherwise it's flatbed to indy time I'm afraid.

so if yu start the car now , you should see a reading and the pump should kick in which you should hear

 

[Craiglxviii]

Sorry to say it mate but im glad im not the only one.... was yours the pump that had gone?

Pump (twice...), strut, lines and valve block all needed replacing or stripping and rebuilding.

If your rear wheels have sunk that low, your valve block will also be gunked up; it will need stripping down, cleaning out and rebuilding. I have the correct O-rings in stock if this is the case.

I have already got under the front and found the pump mate.....I mite just order a new pump and fit it. I have left off all the engine trays for now knowing im going to be revisting it lol. Where is the level sensors on the rear do you know mate?

Level sensors are on the struts as I understand it. Pressure sensors on the front and rear valve blocks for the 221.

Reconditioned pumps for the 220/215/230 are £480 from MB (12 mth warranty)- I do not know if they will fit the 221/216/231 though so it will pay to check. The pumps have come down significantly in price over the last two years.

It is indeed, it sounds odd that the pump has just gone, usually there will be indications, white warnings and odd activity (including a pretty obvious noise!) before it fails completely.

Is this hard to do and where do i find the valve block mate......Again sorry for all the questions.

All done mate.

That sounds almost reasonably priced if it's from MB

Not hard but just time consuming. You will need to make yourself a clean area- like surgically clean, no dust or dirt- to break down the valves, remove O-rings, scrub the shuttle bodies clean then rebuild it all.

Valve block is located on the body next to the rear axle. Aluminium block about 8 x 6 x 4" with 4 valve bodies poking out of it, 2 lines leading in and 2 lines leading out (HP in, LP out and one circuit to each rear wheel).

Yes I was astonished too as it's almost exactly the same as the ones from eBay.

ok but I had this issue on my granddads S class and it wasn't the fuse for the pump that had blown , cant remember which one it was now but I replaced it and 30 seconds later it started to rise up , it was in the big fuse bow on the drivers side

The 212 doesn't have ABC, that'll be Airmatic which is totally different.

 

[DREAMER NO2]

Glad you are around ! And they do have Airmatic .

I may be wrong but do that Googe search. Then kick me after..

Air suspension- says quite clearly.

Right, bend over, this is going to hurt you a lot more than it will me...
