Hi guys i am a fellow E55 owner from over the pond, but i am new to this forum, was wondering if anyone can help me?

I was doing some donuts & power slides the other day, (as you do) and now my steering is so heavy that i can hardly steer the car. I have been told that i need a new power steering pump.

Just wanted to know what other models of mercedes use this same pump? Im guessing that its not amg specific.

Cheers!

Apparently almost all of them. My pump died and used a pump that was laying around in my friends shop, he said it came off a V6 car or something. I know my wifes ML350's pump looks identical to mine ( reservoir is different though ).

BTW- install a new reservoir since it has a built in filter.

F17RAK

ok cool, well suppose i better take the old one off & then go on a hunt.

Is it easy enough to take install? Also cant i re-use the original reservoir?

GT-ER

Do not reuse the reservoir. If the pump failed then the reservoir filter should be clogged with metal particles.

Install wasn't that bad, the reservoir for some reason didn't want to go back on and was a huge pita but everything else was ok.

Thanks dude, youv been a massive help. I read an old post of yours, you sed you got one for free, what car was that from? I only ask because in the uk there isnt many petrol powered mercedes available, mainly diesel.

GT-ER

No problem.

That's the pump I mentioned in my post above, I'm not sure what car it came from.

F17RAK

can anyone get me a part number?

F17RAK

GT-ER, does this look correct?

Neither, look for w211 pumps.

As Shardul says, speak to Aceed (Acid) and he will sort you out, he is based in Birmingham too.

is that whine when we start up the car cold the power steering pump?mine does the whine all the time now and trying to figure out if its the pump or something else

saleen01

i have this problem also, noise goes away after a minute...

GT-ER

Nope...oil pump.

skratch77

you think I should change it or is it normal

saleen01

oil pump? noooooooo...come on?
it only happens to me when the car is cold and i back out and turn the steering wheel, at initial startup during idle...no noise...

F17RAK

Spoke to acid today, nice bloke, knows his stuff. Found out that i can get a brand new pump for around £170.

Even saw & heard his estate (station wagon).

F17RAK

Decided to tackle the pump myself, took it out to find out part numbers. Wasnt that difficult.

£167 brand new, cant moan at that. Here som pictures to help others.





The parts database shows its the same as the cls55 ( obviously) also the 500 engines.

Manuyc

Nice! Prob should change my res also have 68k miles on it

berti_00

I bought one to do it...

F17RAK

reservoir bottle doesn't cost much, that should be here tomorrow straight from mercedes.

F17RAK

I changed my oil pump, new reservoir & new o ring. But its leaking from the rear o ring connection. Taken it out twice but still wont stop leaking. I used this oil

Is there a trick to this, is the bleeding process critical? Does the wrong oil make it leak? Even though i was told its the correct fluid.
