I hope they did not grenade your ABC pump. I'm sure they will try to squirm out of paying that $3000 repair bill.

Most likely they haven't bleed the power steering and ABC suspension system (same pump) so there is an air lock.

Make sure they use genuine oil for both the ABC and PS systems as anything else will cuase damage.

Either way, you don't need to R/R the steering pump to change the engine mounts.

2007 S550 AMG with ABC
As much as I love the ABC in my car, It seems like Mercedes needs to get with the program and switch to a more modern system that uses electro magnetics..

Apart that is for a small leak, so sometimes it says ABC drive carefully.
Then I just top up the reservoir which lasts a few months, will fix it when I
have some spare cash.

That is ridiculous. The car does not have a sensor that measures the amount of hydraulic fluid in the ABC reservoir, and your "ABC Drive Carefully" message comes on for a specific reason - the system pressure is dropping below acceptable range due to low amount of fluid, which in turn is murdering your ABC pump every second that you run it.

ABC is a closed system - you don't need to add additional fluid to it, unless there are leaks. If there are leaks you have to fix the leak, not keep adding fluid every few months...

Sorry have to disagree. If it's a sealed system then you will not be able to top up the oil. I was told by Mercedes that the warning comes on when the oil is low, as it would with brake fluid, washer fluid etc.There is a reservoir for
ABC fluid which has a dip stick. When you add oil it also clears all warnings
without a visit to a dealer, so it must bleed itself as well.

You are living in fantasy land my friend.

I know about the reservoir, the dipstick, etc.. what I meant by a sealed system is that no fluid is "used" or "escapes" while the system is used, so there is no need to fill it up as you would other fluids in your car, unless it was leaking, which it is, which is bad.

That leaky hose might just bust open one day spraying hot hydraulic oil at your engine bay at 3000psi... that will be a fun clean up!

The system does not bleed itself either, I don't know where you got that idea from.

When doing a fluid flush you also change the filter and run "The Rodeo"...

Here is a video my car after I performed ABC service on it - http://www.youtube.com/watch?v=xkRvV2iWZZw&fmt=6

Thanks for your concern, but I just can't afford to spend a grand at this present
credit crisis time, so I will have to top it up until funds become available.
I also have a problem with my SL55 with a tank noise, which also needs a
grand to fix.

If you can't afford $1000 to fix one of the most important systems on your car, why did you buy a range topper Mercedes in the first place.

This stuff kind of annoys me. Just because the used prices have fallen doesn't mean you shouldn't service it like a $180,000 car.

Just means less good cars for those looking for one.

We all go through periods where cash is short, with bills to pay and a slow down in business this is how it's going to be. It does not matter how much a car is new if money is tight it will have to wait. When it does get fixed it will be by Mercedes and not some back street garage.I certainly do not plan to sell it so don't worry.
Please have a little compassion.

I simply can't have compassion in this case. Either you knew what you were getting into repair cost wise, and now are ignoring repairs, which is not prudent, or you had no clue when you bought it, which is also never prudent.

While I understand money is tight, should you really own such a car if you can't spare $1,000 to fix one of the most important parts of the car?

I don't know...

Sorry you don't get it, my business goes up and down according to the time of year, I simply don't have a grand to spare.Come February/March money will not be a problem. The guy at Mercedes said it's a small weep, if the ABC
warning comes on just top it up for now. I carry spare oil in my boot in case
it happens on a journey. This problem is with my S600 and was certainly not there when I bought it over a year ago. I don't know quite how to take
" should you really own such a car" I promise I won't get angry though, I can take it.

The extended warranty (100k mile) was included as part of the deal when I bought the car.

I hope the ABC system is covered since it is part of the suspension.

I think many of the cars now for sale have probably had maintenance neglected so caveat emptor!

cl600 abc leaking -location of likely failure

My 2002 cl600 just gave me the "ABC Drive Carefully" message. Added 1 litre of proper fluid and drove it and light went off. However, lots of fluid leaking from left front just rear of wheel well. Any idea of what component is leaking based on location. I want to appear somewhat knowledgeable when I take it into the shop

Front valve block or the front accumulator area, could be the valve block, or a hose that connects to the valve block

Thanks, do you know where the pump is located --- I think that is the most expensive repair.

It will become much more expensive if you keep driving the car. I would park it immediately and have it towed to a repair shop or fix yourself but do not drive. If you run the pump dry, it will send tiny bits of metal through your system and clog your struts and control blocks.

If you have fluid leaking in the front left wheel, there is a good chance your pump is leaking, which is located there. A valve block will not leak externally, just internally, causing the car to lower after being parked. I would bet that if any of the cars in question were hooked up to star, you would find your abc pressure low. Be prepared to drop some cash, cause the minute the red light comes on, your pump is done and the car will drive like a tuna boat.

I don't know what a tuna boat drives like but car was rocking up and down while driving home. Fluid was low , then drove normally after filling with fluid but is leaking fast. Being towed to shop Monday. Any chance of rebuilt pump if that is the problem or do I just suck it up? Car is not lowering or leaning. Thanks to all for opinions. Does anyone know where high pressure hose is located that is under recall? Mine was replaced under recall once.
