So a bit of a long-winded issue... Had the full set of above fault lights appear a couple of times recently, seemed to be when the EPB was coming on when switching the ignition off. Assumed to be random gremlins as they cleared on ignition until a bigger problem today.
After being parked up for a couple of hours, I started up as normal but the EPB wouldn't release, neither on the light nor physically. Then the above warning lights came on inc EPB failure. Tried a few more times and I could feel a pulse in the brake pedal but no luck with the EPB. Waited a few minutes, tried again and the EPB released but I noticed the pedal felt very hard. Moved off and the ABS/ASR/Suspension failure warnings came on again and the pedal softened back to normal. As miles from home, did short journey, parked for a couple of hours with EPB off but exactly the same happened with the pedal hardness on ignition again with failure warnings, which won't clear for more than a few seconds on ignition.
Now home, I've tried a few more scenarios. EPB is now working normally without warnings but the ABS etc warnings are coming on immediately, and the pedal is hard until after a couple of seconds pressure.
Brakes feel normal while driving, but something is really amiss. It's unlikely to be voltage related as the battery is quite new and always trickle charged showing good health. Car is a 2008 early ZF with Skyhook.
Interested in thoughts of what could be wrong, and whether I need to sell a few organs to get it sorted. I'm around 130 miles from my nearest specialist so can't just pop over, so although it might not be fixable by DIY it'll be helpful for some ideas. If it is not a sensor hissy fit then I'm wondering if it is the ABS pump? I've disconnected the battery for now to see if I get a reset but with the brake pedal symptom I suspect it could be mechanical. Thanks for any pointers of experience with similar issues.
