Thought I'd post this on the off-chance anyone has any idea what this means.
Since the 330i (2005 E90) had a new ECU fitted a few months back, we keep getting this intermittent warning flashing up. Shows the car on the ramp in red in the middle of the BC display & the handbrake applied light remains lit with it.
It is very intermittent, for example I did a 3hr 140 mile drive in it last weekend & nothing yet when I got back in it an hour later to do a 5 min run to the shop, on it came again!
I can't find anything in the handbook that relates to those two being on together & I've checked the two nearest things to it. The brake fluid level is fine & the hill start assist is working fine whether the warning is present or not. I could probably throw this back at the garage that replaced the ECU as it never happened before & I also have INPA but not sure where in it to look or whether it'll even register as the engine management light isn't lit.
Haven't managed to get a photo of the lights as I never know when it's going to happen but just thought I'd try here in case anyone has had the same.
