Dave (Mint) came over today for a little help in removing a broken ABS sensor securing screw with a broken drill bit stuck in it on the O/S/F.
We stripped the brake calliper, disc, hub and backplate to reveal the opn end of the screw hole. Using a 4.5mm drill we removed as much material as we could until reaching the end of the broken drill bit. Next using a carpenter's pin punch we knocked the broken drill back the way it came from and then drilled until we reached the end of the broken bit again. We repeated this until the broken drill fell out, drilled through at 5mm and re tapped the 6mm thread ready for the new bolt Dave collected from Sopers on his way here. Took about 1 hour to do. After we got it back together we went for a butty for lunch at Colbournes Cafe on the A57. I took him for a ride in my Z4.
Cleared the fault codes and after a road test quietly confident we fixed the problem.
Not looking too shabby for a 200,000 mile car is it. I like that ageing blue.
Nice to see Dave again, been a while.
Tony.

to Tony for the loan of his ramp, tools and experience. It was great to have a chat and play Zeds. The broken screw put up a valiant fight but we won in the end. I wasn't too confident as the old sensor was neither open nor short circuit but I had to change it to prove the fault. As Tony said, I called in to Sopers on the way to Tony's, but left with a much lighter wallet, even with forum discount. I'm very pleased to say the fault is cleared, the lights have stayed off all the way home and after a few starts too. I'm a very happy bunny
