MY 2004 D3 electrical gremlins
I think my D3 is telling me its time to be sold, I have had her for 4 and half years now.
Latest problem. Driving in stop and start traffic, out of the blue up will pop a series of faults on the DIS in the following order. Headlight range control defective Parking Brake Fault And another I cannot remember. ABS and ESP lights then come on in addition to the warning, and you cannot engage ACC cruise control. The parking brake still works perfectly fine, if you turn off the engine before engaging. I drove for three hours yesterday morning in regular traffic, and the car drove perfectly with no faults. I got stuck in traffic going to work, and within just a few minutes up pop the faults. The only thing I can think of is that in traffic the brake pedal is being used a lot more than when in motion, can a faulty brake switch cause this?

Yes it can - and has done to my D3 - or at least the ABS and ESP lights part can be (I think that the Headlight range and Parking brake may well be seperate faults)
and the brake switch isn't too expensive or difficult to change so I'd definitely start with that first Your adaptive cruise won't work of there is known issues with the ABS and ESP for safety reasons I would have thought

I agree with Neil, first stop would be VCDS scan to see what errors are logged as brake switch defects will be logged in that

I wouldn't be certain about the brake switch, when mine went the gearbox went into limp mode. I drove it to the garage thinking the gearbox was toast. I was thrilled to be told it just needed a brake switch.
