I have recently got an E28 and after addressing the major issues with the powertrain and suspension (some notes here) I am down to a bunch of minor annoying things that I hope to get some advice on here:
- Squeaky brake pedal. I tried lubing the spring behind the pedal with white lithium grease, but the silence only lasted a couple of days. Is there a recommended lube for that? Or maybe I'm missing some rubber/plastic bushing?
- Sunroof rattles when driving. It's the headliner wrapped around the sunroof rattling on the ceiling headliner. I was thinking about sticking some felt tape there on the ceiling along the edge of the sunroof, but open to suggestions.
- Brake light check light sometimes turns on. Sometimes when I first turn the key in the morning, and in those cases usually pumping the brakes makes it go away. Sometimes it lights up after driving for some time. Sometimes it stays off for days. I checked the brake lights and they are fine, evenly lit bulbs on both sides. I was going to replace the bulbs and clean the contacts, hopefully it's not an issue in the diagnostic system itself.
- Driver door whistles at speeds > 45mph. It's coming from the top of the B-pillar, I am guessing a bad/old door rubber seal. Lowering the window just a tiny bit makes it go away. Is this a common problem?
- To properly close the front passenger door I gotta slam it pretty hard. What can be adjusted to address this?
- Finally, the car is missing the trunk label, "528 e". Does anyone have the measurements or a template for the placement of the chrome lettering? I have bought the new "528" and the "e", and want the car to look as OEM as possible.
