Mercedes Sensotronic brake-by-wire SBC ABS Pump System Failures

Contact Us

Mercedes Sensotronic Brake Control (SBC) ABS PumpSensotronic Brake Control (SBC) ABS pump systems are commonly found on higher end Mercedes such as the E-Class, SL & CL Class, CLS etc.. the SBC Sensotronic ABS pump is a brake-by-wire system and Mercedes Benz were one of the first vehicle manufacturing companies to apply this system to cars.

How It Works
The Brake-By-Wire Sensotronic Brake Control (SBC) system is quite different to the conventional hydraulic abs braking system because it doesn’t have a brake servo at the reservoir to start with and the brake pedal is connected to the ECU by wire. The sensors on the brake pedal offer a way of communication, telling the on-board computer how the brake pedal was pressed, how hard it was pressed & how quickly it was pressed etc. The computer then calculates the required pressure and activates the braking system producing braking force at each wheel via modulators.

The problem with Sensotronic Brake Control (SBC) ABS Pump Braking Systems
The Sensotronic Brake Control (SBC) ABS Pump has a service life (also known as a life expectancy) programmed into the control module which works off the number of brake actuations. Once this limit has been reached, the Sensotronic Brake Control (SBC) light may illuminate on the dash or a brake related warning may appear on the trip computer. Once this happens, the Sensotronic Brake Control (SBC) system is de-activated and the hydraulic braking function mode is activated whereby limited braking pressure is applied to the front brakes thus increasing the braking distance.

When the Sensotronic Brake Control (SBC) ABS pump fails, you are led to believe that the unit will require replacing and in some cases (depending on the vehicle application) it can cost up to £2500-3000 for a replacement unit (+Labour, Programming & VAT).

Connected to the STAR diagnostic system, the fault code C2498 will show the fault code description “Service Threshold Reached” as a current & stored fault code. This code cannot be erased without replacing the system.

How Can Sinspeed Help Reduce This Cost & Fix The Problem?
Rather than replacing the unit with an expensive new part or even replacing with a second hand part (just waiting for it to fail).. we can remanufacture your existing unit and reprogram the Sensotronic Brake Control (SBC) control module to increase the service life expectancy of the unit. This is becoming a very common problem and we’re able to carry out full repairs to these units and offer a very competitive fitting rate.

      Hi Fawzi,

      Even with STAR diagnostics, if you have the SBC Life expectancy threshold fault then you will not be able to resolve this issue with just a STAR machine. You will have to replace the unit for a new unit or send us the old unit for reconditioning. Please send us an email or call us for pricing and more information.

    Hi,

    I have an ML500 2002 model. This car started to have the ABS/ETS lights come on the dashboard (sometimes only) and reading your feature above (which is very helpful) I am wondering if my problem is actually the ABS Pump.
    The brakes perform as they should before the lights come on and even if they don’t come on so my stopping power hasn’t reduced at all.
    Do you guys think there could be an electrical connection or sensor problem arising from the brake pedal, which might be the real problem and not the pump.

    Cheers

      Hi Graham

      Common problem on this vehicle is the wheel sensors and the steering angle sensor, more common than the ABS ecu itself.

      Please call our office for details on 0871 2887 666 or alternatively if you send us a email, we will get straight back to you.

    I’ve got a E270cdi 2002 and just got the white malfunction warning on my dash “service brake visit workshop” and am about to find out through MB tomorrow what state the SBC pump is in, ie if they need to replace or can reprogramme it. I’ve only just come across your website and read about what you can do.
    Are you able to give an idea of cost and time involved as I use my car for airport transfers and cant be without it!
    Cheers

    Dear Sir,

    I have the W211 in Kenya and have the SBC problem on it. Would it be cheaper for me to bring it to the uk than getting a new one and on a previous post you said you can give a life time warranty on it, is this correct.

      Hi Stephen

      Thank you for your enquiry,

      Yes we can remanufacture these units for a fraction of the cost of a new unit and no programming will be required when fitting the unit back to the vehicle. We are offering all remanufactured SBC pumps with our Lifetime warranty. For pricing and more information, please email our support team.

      Hi Tony

      Thank you for your enquiry,

      We offer two types of services for this particular fault and urge customers to bring the complete vehicle into our workshops for a faster turnaround and better success rate. We can work with the SBC units on the bench if you remove it from the vehicle and send by post but the success rate of repairing them in situe whilst fitted to the vehicle is much better. For more information and a quote, please email us or call on 0844 847 9999.

    Hi
    I called yesterday to discuss the ‘dry squealling’ sound that the pump makes first thing.
    Is it on it’s way out ?
    Do you have a workshop in Basingstoke where it could be serviced ? ( we are in Winchester )
    As yet, no dash warnings. 170k miles 2003 320 cdi reg 871D
    Kind Regards

      Hi David

      Thank you for your enquiry,

      I would recommend the vehicle comes into our main workshop in London where we remanufacture the SBC Pumps. It sounds like the valves may be on the way out but if that is the case, it can not be repaired. All we can do is flush the fluid through with clean fluid and re-bleed to see if that helps solve the problem. Once the valves are damaged, you must replace the SBC Pump.

      Kind Regards

    Hi, my sbc pump has displayed a white warning light on dash. If I get the pump reset , how long can i typically expect from pump before i could get a red waring light, ie what is the expected lifespan. I have an eclass 04, 130k miles.

      Hi Brian

      Thank you for your enquiry,

      We can reset the life expectancy of the pump to how it would have been from factory. So if it’s lasted 10 years then it would last another 10 years before it flags up again. Our SBC Pump reset service comes with a Lifetime warranty so if you have it reset by us once, we will reset it again if needed in future.

      Kind Regards

    I own an 03 E270 CDI with 90K miles and I have just got the “Service Brake Visit Workshop” message come up. I am informed that the SBC pump is showing “end of life” but i understand this unit can be reprogrammed and the life extended. Can you do this, does the unit need to be taken off the car and how long does it take? How much does it cost?

    Regards

      Hi Mark

      Thanks for the enquiry,

      We can definitely help with this and have a few options depending on a few factors as follows:

      1. 10-Digit Bosch part number starting with 0265, located on the unit on a yellow sticker.
      2. Are the brakes still functioning?
      3. What colour is the warning light? (White / Yellow / Orange / Red)
      4. List all the fault codes you are getting on the diagnostic report.

      With the above information we can quote exactly how much it would cost to rectify and we can carry out most repairs with the unit on the vehicle.

      Kind Regards

      Hello

      Thanks for your enquiry,

      We’ve got brand new genuine parts and also reconditioned SBC units in stock. We can possibly also repair your own unit. Please call or send us an email with further information. We will need the 10 digit bosch number from your SBC unit, the fault codes relating to the SBC faults and whether the vehicle is still drivable or if the brakes have failed completely.

      Kind Regards

      Hi Chosen

      You will need to get the SBC fault diagnosed. We do offer diagnostic services if your local garage is not equipped with the adequate equipment to diagnose this fault.
