Guessing from reading the forum it's the pump? Was working a few days ago. Tried disconnecting the battery to remove the lights. Came on instantly. Lift button does not work. Check Engine light on. Just power washed my car, anything I could of damaged?

Also need to replace the brakes. Squeeking scrape noise by rear wheels when going slow. Could the electronic kicked the ABC off for safety?

Just scared it's the pump. Has 160k miles, paid $6k for it in December. Then I bought some nice deep dish wheels for $3,500. Had to replace the accelerator, then I have to replace the left blinker and both high beams. And some one side swiped my passenger side view mirror, light broke, as well as brake light cracked, nothing on the body though.

Honestly, just might sell it fml...... I love it too. Just so expensive.

is the light white or red? and are you still driving it?

Pressure washing is the enemy of These cars. I doubt it's the pump they usually give warning like groans and grinding . Probably electrical damage

If you have Comprehensive coverage in your car insurance they cover water damage

First get it hooked up to Mercedes star COmputer to verify the problem

Have you checked the fluid level in the ABC reservoir?

Check the electrical connections on the strut tops.

Inspect the suspension level sensors at each corner.

Does the power steering work OK?

So I took the car out last night. Suspension is working fine again lol. That means it's prob not the pump right? I'll check the stuff you guys listed and let you know.

The Light was the red ABC Drive Carefully light. I unhooked battery to see if it would go away but cam on instantly. Suspension fine now though.

Power Steering is fine. There is a humming sound when I drive, but that might just be my low profile tires, they are pretty loud. And there is a clanking/scrape sound at the rear wheels but pretty sure it's because I need new brakes.... bad.

When the ABC was on it was driving like a boat in the ocean, was gonna get sea sick. But it seems fine now.

Good news.

Do you hear the humming sound when stationary?

Nick

Nope. But the light is back on now, this time the yellow ABC light instead of the red. Leaking oil now in the front too lol. Actually tbh after I took it in for an oil change months ago, the engine oil level **** car light comes on all the time. He said he probably damaged knocked the sensor and don't worry about it. And the light came on the the brake bulb on the left is going out. And after a hard rain yesterday, water is leaking under the passenger dash lol.

Taking it to a shop tomorrow, but he's not a Merc guy, just said he does some stuff lol. I'm f*cked. Wheel noise is getting louder, hope it's just the brakes. Clanking noise not a hum. Almost like something is hitting the inside of my rims lol.

Sounds like blown accumulator(s). If you're a DIY guy then not a big deal. If not, well...

Not really. I mean give me a Chevy truck, I know a little. Merc's... nada. Got a date with the mechanics tomorrow. What's it gonna cost me about? Mechanic is a half hour away, going to be driving on the highway after filling oil back up. Safe to do that?

Looking back on your original post you've got a lot of issues and if you don't have some mechanic skills, it's going to cost you a lot of money. Other than the ABC issues, it sounds like you have got other worn suspension parts like maybe control arm bushings. Your Reed valve is probably clogged and that's where the water in the cabin is coming from. Mercedes made these cars pretty easy to work on (in my opinion anyway), so search the forums and YouTube for helpful guides to repairing a MB yourself. You'll save mucho $$$.

Guessing that means at least a few grand right?

If there's water leaking under your dash your reed valve is clogged - open the hood and look for the waffle plastic under the passenger side windshield

Unclog it immediately by running a long chopstick or screwdriver through their drain hole

The water will come pouring out under the car instead of into the cabin



You must absolutely get all the water out of the reservoir under the windshield before you start the car again. Then pull up your carpeting from under the dash and soak up all the water runninh in the electrical trough that's under the carpet . It runs from front to back to the rear SAM

If you don't clear out and dry all the water under the carpet you'll damage the entire electrical system as things short out when wet and powered on, so it's essential you dry it out under the passenger carpet using a hair dryer , towels or whatever you have handy before you start it or drive it to the mechanic

Here's a video that shows it better - if your rear carpet is wet the seats need to come out to dry everything. Hopefully you caught it early before the water goes to modules in the back seat

Thanks Tusa!

Update from the mechanic. Car is there overnight till I figur out what I want to do.

He said the leak and the ABC light is because the pump went bad and is leaking. Said part alone is $2400. Is the leaking under the front of my car not from the water leaking under my dash from the clogged reed valve?

Front brakes need replaced. He didn't say anything about the back even though that's where the noise is coming from. Another $500 though.

He said it's going to be 3k total.

Does that sound accurate to you guys? Have to make a decision by morning, closed now.

The water leak under the dash had absolutely nothing to do with the abc pump it's the reed valve . Two separate problems

It's called a power steering pump because it's the same pump for both abc and ps

You should either find another mechanic or just see what his labor charge is if you supply the abc pump. Do not pay $2400 for an abc pump

Grab your car and run. Find an independent mechanic that specializes in European cars. Hell, a brand new pump straight from Mercedes cost half that. He's going to do nothing but rip you off.

Thank you!!! Was about to put the 3k on a credit card, then sell the car when fixed lol.

Ok I just turned him down. Pretty angry lol.

Anyway he said the power steering should go out soon then.

Kinda confused... I know you guys said the pump is the same, but if it's the pump that is for the suspension and making the ABC light come on, why does that have anything to do with the power steering?

It's two different pumps right? Same type.

it's a dual pump, but i believe normally if you have fluid the steering should be okay. i think the abc needs significantly more pressure to run than the steering. i could be wrong. you can also get a rebuilt pump from napa. i believe they sell the cardone pumps. i would assume using a rebuilt pump the job should be around $1500., only a guess. could be less possibly depending on who does it. ask your mechanic if he'd use a rebuilt pump and his price. i think $500 if he's just replacing the front pads is extremley high! if that's the case find someone else.

Will those parts you guys listed fit mine? Probably a stupid question but my vin starts with WDBPJ75

Every part I checked online, Vin starts with A...

You look at the LAST digits of the vin not the first ones!! Where the vin says A then the sequential number. If the last digits in the number is above the cutoff get the ac Delco pump

If the last digits are below the cutoff get the a1 cardone pump

Example for VIN Number: WDBPJ75J12A030447
The digits you should be looking at are the A030447, at the end of the vin


Rockauto.com has the best price

It's the same one pump for both abc and power steering , the one pump it handles both functions. It has hoses going to both the abc and ps systems. But It's very common for it to still steer fine but lose abc pressures

Haha I'm so stupid, Thanks buddy! A028774.

Probably going to get the Cardone one if it doesn't matter.

Good luck ! I hope the new pump solves your problems and you find a good mechanic to install it , remember when installing it must be primed before restarting the car -otherwise you'll ruin the new pump . Fill with new pentosin chf11s fluid in both the abc and ps reservoirs (there are two separate reservoirs next to each other). Prime the pump by Turn it by hand to prime and also , with the front wheels raised in the air , turn the steering wheel lock to lock 30 times before you start the car



don't forget to clean out that reed valve under the windshield so you don't have any more water under your dash during rains or car washes

Buy yourself a full set of brake pads while you're on Rockauto. If your rotors are grooved go ahead and buy them too. Replacing pads on these cars is so damn easy. To bad you don't live close to me I'd do the brakes for you and my Indy mechanic lets you provide your own parts. Get these few issues sorted and drive your car past 200k miles.

You guys rock! Really appreciate the help! Was about to pay that guy the 3k.

Btw he originally told me $2400 for the part, then when I got there to pick the car back up he said he can do it for $1500 lol. Anyway ordering pump now. Appreciate it guys!
