HDC Fault
I'm new to the forum having just bought a G4 Disco3. Everything's been great for the first 2 weeks of ownership but today I've got a message stating 'HDC fault system not available' along with a flashing adaptive front light warning. Suspension is also in limp home setting. I've searched through lots of posts but the usual ideas ie brake light bulbs and battery seem to be OK. Any advice and help would be greatly appreciated. Thanks

My bulbs have looked okay but still changed them which cured the problem

A friend has a code reader and after clearing all the list of small faults the one that won't clear is Vehicle Dynamics Control Module. Anyone know how easy this is to fix?

Mine did exactly this,(see my stranded in France thread), garage diagnosed a faulty solenoid within the high pressure fuel pump assembly. Just got it back today, so far so good..............

Code on the HawkEye is V0416 (could be U0416) says received from vehicle dynamics control module and on the other fault reader it's U0400 algorithm based failure. Bosch yaw module on eBay for £21 do you think it's worth a punt? Cheers

What module.has lost comms with the VDM, and what codes are stored in the VDM?
I would expect to see a P or C code stored someplace in the car, unless the fault is.voltage relatedMy D3 Build Thread

Initially there was a code reading Rear cross link valve C1A38 but it said intermittent and it then cleared. Cheers
Ps I've tried to upload a photo but it's not working.

Turns out it was an ABS sensor on one wheel. Fixed in less than an hour at Gemm 4 x 4. Thank for all the suggestions.
