Well done, perseverance pays, Don't forget the thanks button again.
& send me some of the money you saved.
Tell me, when you connected to the car, did the connection icon on the task bar come up OK or was there a big red X ? I'm getting that, but It still seems to work.
IMHO the garage did start the problem, but the relay would probably have failed eventually.
I've been following this thread with interest, have had the EPB nag, but never stripped the box. I hope I don't have to, but I thank you for showing me & other readers the way round, should we ever need to.
Do hope you stay & enjoy the craic, unlike the many who join, get help, then dissappear till the next fault rears it's head. Perhaps that's why there's so many diseasel owners on ???
