well...after 2,5 months of replacing the turbo and rear springs etc on my car I finally got to take my car for it's M.O.T yesterday but asked them to replace the inner right CV Boot for me on the driver's side. So, then the car comes off the ramp and they start with the MOT and I notice my right rear break light had gone, suddenly, - no problem luckily had a spare globe in the trunk ...sods law it went right then but it is only after they had done with the M.O.T and I am very happy to say RED passed with only a very very minor advisory on a wire that is rusting and probably want to spray with rust inhibitor or something and cover at some point, that I noticed something strange with my lights. When the MOT person took my car out of the garage I noticed my right front running light flickering on and off...mmmm...never seen that before...then I also noticed that my rear led break light is on when the handbrake is engaged...also a first. But it was not until I drove my car home and suddenly my glow plug symbol started flashing in my dashboard...grrrr. here we go I thought. So I got home and I immediately came onto the forum and low and behold someone else had similar symptoms and it seem to boil down to a switch. Now, I know I only removed the oil temp sensor to get to the oil feed pipe for the turbo so probably want to check that but I rang the garage and my friend said to bring the car and will put on the diagnostic scan and by that time I narrowed it down to the brake switch and that sensor, I hope. Scan showed the same and the brake light switch came up as an issue so popped over to Euro Car parts across from the garage and bought one for £15...
So my job this morning is to open it up under the dash and replace that switch (fingers crossed the switch is correct part) and then hope it solves this problem.
Now I am just wondering...as my car did not have this problem going in to the garage, did the hammering on the wheel on the right hand side have anything to do with the possible failing of the switch? If so...may be something for other people to have in mind when going through the same work of replacing CV`s etc?
