Progress on the BMW Z3

After purchasing my Z3 1.9 back in October 2019 and having all the mechanical items sorted it was time to put the Z3 to bed for the winter as the weather was not up for me working on the car. 

The winter was spent Googling, watching YouTube, talking on Z3 forums and basically working out how I was going to tackle the items that I had found needing attention on the car. As with any car of its age, the list of jobs to tackle was not a small one.  

The main items needing attention were to replace the sills, fix the central locking and interior light not working, body work and refurbish the leather seats.  

Sills were purchased from Sytners Sheffield, painted by a local body shop and fitted one weekend. The frame under the sills looked to be in good condition with some surface rust. The frame and back of sills were treated with wax oyl before the sills were fitted. 

 The issue with the central locking turned out to be a familiar issue with the Z3, a broken cable in the loom going from the boot. A bit of soldering later and the central locking works as expected. The interior light not coming on when the doors were opened turned out to be a simple fix too, the connection of the wire on to the light switch just needing a clean. 

After a trip in February to the Leather Repair Company in Hull with the Eastern region we felt we had all the knowledge, and a repair kit, to refurb the leather seats. The transformation is astounding and well worth the effort. We re-dyed the leather whilst the seats were out of the car since the bushes on the seats needed to be changed to stop the seat moving back and forth. Changing the seat bushes turned out to be a much easier job than I thought it was going to be, just having to remember to count the number of turns for the runner.   

Whilst the seats were out of the car, I took the opportunity to put my hand under the carpet. When I first got the car there were no rubbers on the hood that go above the door and the inside was soaked. The foam under the carpet on the passenger side was soaked in water and squeezing the foam caused a torrent of water to release. I pulled the carpets up as much as possible squeezed out as much water as possible and left to dry out. It took three days. 

The body work required some attention on the front bumper and both rear arches. A couple of small rust spots on the arches turned out to go a bit further once sanding commenced. After some sanding, filling, sanding, primer, base and lacquer the car looks great. The body work still needs some attention and a good machine polish at some point. One thing I learnt from spraying the bodywork is that more base colour and lacquer is required. You’ll never get the same quality finish from a spray can as you would from the body shop but it looks presentable now at least.
