So, I failed the MOT on two rear arms, ABS fault and a missing seatbelt (oops)..
Obviously the rear seat belt was easily sorted. Was hid underneath the rear seat.
Next I fitted 2 rear arms which was easy enough. I plan on doing a suspension overhaul during the winter when the car is off the road, but since I kinda need it atm to get to places I'm just doing whats needed for the MOT
I also replaced a couple of SLS Flexi hoses for the rear suspension while the car was in the air. Got the hoses from BM
Then I replaced the front coolant temperature sensor.. the rubber O ring on the old one was out of shape and caused a massive coolant leak while the car was off the road
Started into trying to diagnose the ABS fault. I read the codes with INPA and 'brake pressure sensor' fault appeared. So.. I decided to test the sensor before shelling out £120 for a new one. I broke out the multimeter and everything checked out. I then tested all of the wheels speed sensors on INPA and they checked out to0. That meant the only thing left to test was the ABS module . So off it went to England to get tested/repaired and thankfully it was at fault and they were able to fix it. Some are unrepairable and the unit is 3k from bm!. At least now theres no dash lights on ! which is a rarity for an old bm haha
Passed the retest with no issues. MOT tester was more interested in talking about her than actually testing it lol. Didn't know she passed until I seen the certificate laying in the passenger seat.
While I was waiting on the ABS module to get repaired I thought I'd do a bit of interior work. The head unit didn't work, there was a backlit screen but that was it.. no radio, nothing. It also didn't fit properly, it looked absolutely awful. So I pulled it out and quickly realised it was of an e53 x5 lol. So I bought an e38 one from a friend in England in perfect condition alone with a proper e38 surround. Plugged it in and ... it didn't work either. Had the same problem with the 740 I had which was the outdated traffic master feature in them. For some reason it blacks the screen out, but you just have to bypass it in the boot.
With the screen now working, there was still no sound of the radio. Again, had this problem with the 740. So I pulled out the radio module deep inside the boot.. replaced the fuse and took the module apart to address the 'dry solder' problem a lot of e38s suffer from. So I re soldered all of the common dry solder joints, reassembled but still no sound. Decided to borrow the amplifier from the 540 and that fixed the problem. So, got an amplifier from my mate in England and reassembled everything.
Since I got the car the gearbox would always go into sport mode. I actually knew about it when I bought it, bit of a risk but I thought it was something electrical and not an actually gearbox fault. Friend in England sent over a gear shift selector which took 2mins to replace and cured the problem. Also replaced the broken leather boot around the gearstick selector. So easy enough fix, operating perfectly now
Clayed it over easter which took forever but it was worth the effort.
