Thread: Transmission fault/HDC fault

Hi there,
Electric brake controller, I had no end of problems until I wired it into the trailer connection in the back left hand side of the vehicle, never had a problem since. Also shorted out the tranny module once when I washed the engine bay out, that was a steep learning curve.......... Thank goodness for Faultmate MSV2 I say.

I have had the gearbox fault, emergency park brake and suspension faults come up a few times in my D4 and the culprit was a badly adjusted brake pedal switch.

These same faults as other have said can be reproduced if you depress the brake pedal and accelerator at the same time, confusing the computer and bringing up errors.

I'm after one too.

Hi Rich - yes, will ring around tomorrow.

Let me see... 8 pounds in UK... about $20 in USA... what do you reckon they will be here? I had better have one last drink -before I sell a kidney.

Cheers,
Rob

With postage from the uk it comes to about 35, or from the us 40 all up.
Brett...

Rich - just rang my local dealer (man!) and it is about $27 and they have them in stock.

Thx Rob, I'll contact my local mechanic then.

Thanks everyone for your help, especially bbyer and 400HPonGas. Bought the new replacement brake light switch on Ebay Australia from landy_bits2010 part# XKB 500110 for $35 came within two days, took about 25 seconds to fit it, all the alarms have gone away. Thanks very much.

I haven't been so lucky, fitted a new switch yesterday and replaced the blown brake light that I didn't even realise was blown and today I got the errors more often than I ever have before. Previously it would pretty much fault once then be ok for a while, this time it went three times very quickly while on the Gateway motorway so I got off and headed back home and it still went another couple of times on the way home. Took the gear I had in the back out and into the Series 3 Game and off we went again, no faults in that one at least .

Is there anything else that can cause these errors together, Transmission fault, HDC fault, Suspension fault? It is always in the same situation, hill or slight rise, put the foot down to get up it and everything dies and goes into limp mode. Pull over, turn the car off for a few seconds, start it up and off you go again until the next time.

Thanks,
