Recently purchased a 2004 e320 wagon and been going thru it changing fluids/filters & learning how everything works. It had a very strong fuel odor in garage yesterday after 1st fill up.

Removed inspection panels & confirmed leaking on drivers side around fuel delivery lid. I intended to bring car in to dealer for the brake fluid change to ensure SBC pump was checked out, so called to schedule for both & they said bring it in now. They called back end of day & confirmed fuel leak fix is covered under extended warranty.

Also during a step of brake fluid change, tech uses computer to lock up each wheel individually & confirm wheel won't turn. He found when right front was supposed to lock, it turns freely but left wheel is locked up & vice versa. Investigation concluded that when dealer in Florida replaced SBC pump, right & left front brake lines were crossed up!

They had to work at it to make this mistake, because he also found brake line was bent to make it fit in wrong position & also was rubbing against another line.

Pump was replaced at 98,000 miles, about 6 years and 31,000 miles ago. So all that time, if car had emergency requiring anti-lock or ESP, could have been serious or fatal consequences. Waiting on parts now, before I get my car back. Don

It looks like this is an older thread so hopefully some of you more knowledgeable Merc owners are still receiving new post alerts. I just picked up a code reader and got 3 SBC error codes.
c2258
C25d9 inspect wheel brakes for mechanical faults
C244f L6/2 (right front speed sensor) test wiring plug connection

I deleted the codes drove around for a few days. The only code that has come back is: C25d9 inspect wheel brakes for mechanical faults.
I can't find any information on this specific code, but I'm wondering if it's a problem with the SBC hydraulic brake unit? Any insights? If it's going bad I'd like to get the recall work done (Recall Campaign 2005070007 APR06
Inspect SBC hydraulic unit, replace as directed). My VIN number is included in the posted information on this thread.

Version information:
Control unit: SBC
MB No: 0054317812
Supplier: Bosch
Hardware status: 7/04
Software status: 48/05
Diagnosis ident: 00/16

The 04 hardware seems to suggest it's never been replaced (I'm not the first owner). I'm guessing the part doesn't have to be bad for a recall? Any help would be appreciated.

You have SBC A005... which is the replacement of the first units with part numbers A004... which failed in the first few years. Your SBC was most likely replaced under the extended warranty. Clean the SBC block and see if there is a green round sticker on it as well which is another indicator for a replacement.

Hardware status has nothing to do in the indication whether replaced or not.

Maroc_Specops

Hardware status: 7/04 has everything to do with the replacement.

mijn w211 has Hardware status: 2/13 on it, so its manufactured batch from 2013 februari. Thats an indicator of a replacement don't u think sir ?

Mackhack

No I don't.

Maroc_Specops

I know better then u stubborn trump voter. I live in Germany, its my 5th E class, the 2nd one with SBC. U may declare urself a MB fanatic, but ur definitely not a Engenieer.

SBC hardware status is very important guys, and an indicator to know if ur PUMP unit has been replaced. Don't listen to MAckhack. Hes mad.

ponderingnugget

Thanks for taking the time to share some knowledge with me Mackhack and Maroc Specops. I’ll look for the green sticker. I realize hardware status doesn’t necessarily mean that the hydraulic unit hasn’t been replaced, but I purchased the car used so I’m trying to do some detective work to determine if certain parts have been replaced or serviced.


Mackhacck, you’re excellent knowledge of part numbers may be the missing piece of the puzzle, but I hope not, because that could mean lots of money out of pocket for me. Maroc Specops that was my thinking, the car is a 2004 model with a 2004 hydraulic unit so maybe it is original unit. It might be easier to check with Merc, maybe they keep records of recalls? In any case, I have more research to do. I’ll post again when I learn more.

ponderingnugget

By the way, do either of you have any insight about the error code: C25d9 inspect wheel brakes for mechanical faults? I still have been unable to find anything on that specific code.

Mackhack

Your SBC was made in 2004 with an A005 part number. It wouldn't matter if it was made in 03 or 02. Early SBC units had A004 part numbers and failed sooner rather than later. The first units also had the build in threshold to through the infamous error which was raised way higher in later revisions of the system.

That being said, even the latest SBC units with A009 will fail eventually. It's part of life. Nothing is built to last forever. My two A005 units have over 630.000 on the counter and still working.

Maroc_Specops

Nothing last forever only the Pyramids.

The Later SBC revised pumps inc. the one with hardware status 04/13 have internal upgrades. Bigger brushes, better materials inside etc.

I have a 2005 model year (Europe 2004) w211 just purchased it in April this year. Ive seen it has the upgraded pump. Also this revision has the counter lifted up from 300.000. brake actions to possible 750.000 break actions before it will give u a warning.

SBC has software updates but also hardware updates, thats why there are different part numbers.

MAckhack ur logic is incorrect. How can u claim that a car from 2004 has a SBC pump from built year 2013 and u say it isn't an indicator that it has been replaced. Tell me. Whats going on in ur head ?

Maroc_Specops

I used Brembo Pads, a lots of dust but good brakes. Maybe wrong pads, loose Sensor ? I would advise u to jack this baby w211 up and remove a wheel so u can visually inspect it fore some visible damage etc.

good luck pal !

Mackhack

I'll quote myself.

Maroc_Specops

why do u respond No then. ur a Fugazy. Not willing to recognize my conclusion with I reached, long before u started to realize I have a point.

Good luck with urself dude.

Maroc_Specops

Remember, if u get some error (not the red one) try to replace the brake pedal switch first. 14 $ and 5 minutes work. They tend to fail.

ponderingnugget

I do get the red error on the dash readout of the car, along with a yellow ABS light. However, it doesn't occur when I'm driving, only when I plug in my code reader. As soon as I disconnect the reader, the error on the dash readout disappears.

Maroc_Specops

thats normal when u try to read out the sbc memory for faults in the ecu. U can clear it and get out the OBD2 cable asap than its cleared and safe.

nothing t worry about.

ponderingnugget

I've cleared the code several times, but it comes back as soon as I scan again even if I don't drive it. This is one of two recurring error codes that come back every time I clear them and have got me looking for a fix.

Maroc_Specops

its because of u reading codes. stop reading them and then complaining why it gives the error.

ptkacik

This doesn't make sense to me. You don't have an error code (check engine light) but when you plug in your OBDII reader, it throws a code. Then when you unplug the reader, it clears the code.

Is that correct?

Peter

N_Jay

Sounds like your reader and the car are incompatible for some reason. I blame the reader.

ponderingnugget

ptkacik, that's correct. N Jay, I'm using an icarsoft mbii designed specifically for mercedes and as far as I know is compatible with my car. I've just decided to drive it and hope for the best at this point.

I failed two smog checks 1.5 years ago due to problem codes P0456 and P0446. The codes are related to emissions and it resulted in a major inconvenience. An independent mechanic
replaced the charcoal canister shut off valve among other repairs and remedied the problem; is the canister valve part of the "Covered Fuel Tank Components" w regards to the extended
warranty for the fuel assembly? Also, during this time the inside of the car smelled like gasoline but when i brought up the issue
with Mercedes the dealer told me that my VIN was not included in any recalls pertaining to the matter. If i remember at the time the fuel issue was only being extended to E55 AMG cars.
I could be wrong. Service rep also never mentioned Recall Campaign #2008-020001 which is a voluntary emissions recall campaign when I asked if there were any outstanding recalls for my car.
I have the receipts for both failed smog checks and the work done regarding the charcoal canister valve, if i bring this up to Mercedes how should I go about it? Will they reimburse me for expenses
incurred? Does the fact that the emissions recall was voluntary mean that the service rep was under no obligation to inform me?

I am going to be there tomorrow morning due to a related incident that just happened with a ruptured fuel tank so I want to address this as well.

Anyone with any knowledge please advise.

2005 e500 - charcoal canister is not included in fuel tank extended warranty. 20088020001 apples to AMG only therefore, not applicable to your vehicle.
