    Help Merc E240 sbc issues

    Hi folks got a 2003 w211 E240 with the dreaded red dash and esp issues due to the sbc system, ran a check with diagnostics and it comes up with the code c228f A7/3n1 sbc control unit internal fault is there anyway of tracking this code down to the component or is it a full refurb on the unit. The system is holding pressure at the right parameters so the pump and the reservoir are all fine and all the sensors are working perfect

    Many thanks in advance for any help

    I can recommend ECUtesting in Heanor.
    If I remember the faulty is a tft pressure sensor that pack up, but its a strip of the pump and being a brake component best left to the experts in my opinion.

    Run your wife a nice hot bath, light some candles & pour some wine. Then you've at least 40 mins on the xbox plus a clean wife.

    Experts... x is an unknown quantity and spurt is a fast drip.
