Had the dreaded red SBC failure first thing this morning, very limited braking ( great cure for constipation) luckily I start work very early and not much on the road, managed to pull to side of road, turned car off (03 E55) re started and all back to normal again, drove to work and back with no issues, obviously I’ve got to sort ASAP has anyone used John at auto electrician London? I phoned today and he can turn unit around within a week. Codes were as follows. C26BB C26DE C249E C14BE. Only thing I noticed under the bonnet was small amount of brake fluid around brake reservoir cap, probably from excess pedal pressure when I tried to put foot through floor. Any advice on welcome.
