Another day, another fault Actually, it's been pretty much faultless beyond the things I know need doing for the last couple of months - since the alternator and door lock were replaced.

Drove it about 20 minutes this morning, parked up, sat there for a bit chatting (was dropping the OH off somewhere) and when I restarted I had "Suspension Fault" and a yellow triangle in the dash.

After I'd driven off, the first time I hit the brakes I had an additional "Forward Alert Not Available" pop up, then disappear, then pop up, then .. you get the idea.

Hitting ~25mph the Suspension Fault yellow triangle was joined by "Suspension Fault Max 30mph" and a red triangle - I assume that's just reinforcing the first fault.


My gut says electrical fault, given the two apparently unrelated faults and especially as the Forward Alert fault came and went umpteen times on the return 20 minute journey - and on arriving home I stopped & restarted and both faults had disappeared; tested the suspension - down to access, up to off-road and back to normal and it did everything without complaint.


Any suggestions for common wiring areas that might affect both systems? Front wiring common to level sensors & forward alert, maybe?

Well .. there's been rain, that's for sure; though I haven't been through any big puddles, the OH has been driving it for a couple of weeks so maybe she's been wading through floods without telling me

It's damp, cold, orrible condensation weather so yeah, water in electrics somewhere is top of my list of suspects - I'm imagining there to be a place where wiring common to both systems arrives. Hopefully not the BCM..  2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S
