Just bought a 330ci convertable, roof works well but a bit noisy. What maintenance can I do, I'm thinking about lubrication mainly to ensure trouble free use in future and should use of the the system be kept to a minimum to avoid failure?
Lubrication of the roof is part of regular maintenance.
Preventative maintenance is the best bet to keep the roof from failing.
- strengthen the windshield latches
- strengthen the bat wings
- apply the bolt fix to the motor under the rear seat
- check line #23 and 24 to see if they are about to split. If so try to adjust the lines to provide a bit of slack to prevent splitting.
- splice in new wires at the first bend where the harness usually breaks.
These all take time, although only cost $50 in parts.
The hydraulic cylinders will fail regardless of use, so you might as well use it!
