Suspension + DSC + handbrake + brake warning lights

[af3556]

I was travelling along a dirt road near Newnes when my 2008 D3 suddenly **** itself and "everything" dropped out - the dash thew up errors for the DSC, handbrake, brake warning lights, and suspension dropped to the stops. At the time we were going round a bend and we briefly lost traction (i.e. I guess we were unintentionally relying on the stability control).


These errors are persistent: even after leaving the car off, and disconnecting the main battery for a period, they don't clear. The fact they all triggered simultaneously suggests to me they're not all genuine. A web search suggests either a faulty battery or brake switch - battery voltage is 12.2 V when the car's been in the driveway for about a week, which I believe is more or less ok. Not sure how I can find and test the brake switch.

Thoughts on anything to check before heading into the stealers?

Rgds,

A failed ABS sensor circuit will cause those faults. Check the wiring harness behind the left front wheel to see if it has pulled away from its flimsy clip to the chassis and allowed the inside edge of the tyre to rub through some of the wires.
Did it drop to the stops or just to access height?

Thanks Graeme, you were pretty much on the money. The front ABS cabling seems all fine to me, however the rear ABS sensor had broken off at the mount point. Also the CV boot cover was damaged (leaking) and the parking brake cable loose from its retaining hook. It looks like a stick or such has gone up and made a bit of a mess.

Southern Classic in Wollongong estimate a bit over $500 to replace the sensor, CV boot and grease repack (apparently replacing the CV boot takes a couple of hours). I appreciated they took the time to show me exactly what had failed, and were good in answering my questions.

(It had dropped to the stops: lower than I've ever seen it before and passing through every little bump in the road. It was so low I felt like I needed some doof-doof music and flashing neon underneath when driving into town...)

Thanks,
Ben

I was told that it takes so long to replace the boot that it is actually easier and marginally cheaper to replace the whole CV unit, parts cost more, but labour costs a lot less.

I had these same faults come up on Friday. Took it to Melbourne City Land Rover on Saturday and they said that the computer showed EGRs faulty and Brake switch faulty.
Said to replace the EGR's requires a body off job and will take 6 hours labour plus $508 each EGR. (There are two.)
I appreciate them looking at it at short notice, but if its potentially an ABS sensor and I can avoid 3 days off the road and a couple of thousand in repairs I will!
After reading this thread I think I will be asking them to check again before mid January when its booked in..
Any other thoughts?
Cheers

It had dropped to the stops

I'm surprised it dropped right down as LR documentaton states that faults reported by the brake system only caused safe height which is about access height. It might be worthwhile to inquire if there are any outstanding software updates for the suspension ecu.

Is this for a 2.7 and if so, has the procedure changed because many 2.7 EGR valves have been replaced without removing the body.

Thanks Graeme
I am only repeating what I was informed by the stealership on Saturday
Happy if its just the ABS controller. Although as I said, they also picked up a brake switch fault..
Lets hope it's something relatively cheap!
Cheers guys

EGRs do not require the body off but will result in skinned knuckles and lots of profanity - so I am told. Thats why I blanked mine and just connected the new EGrs to the electrical connector.

My new EGRs were $200 each delivered from the UK.
