My car is due for service as indicated by the dash icon. Is there a checklist or something like there was for my 330xi? I'd like to see what the service actually entails.
Your vehicle used what is called CBS (condition based services) basically meaning the car tells you what it needs, this is stored on the key and read out by a key reader at your local dealer. You can also go through you scroll menu in the vehicle and see what is in yellow meaning do soon or red which means over due.
It's icon number two. The manual gives no further information. If it's just routine service, I would expect there to be a checklist that is followed. Are you saying more detailed information is stored on the key? If so, that's a really bizarre place to store additional service information.
If there is no further text along side, that might be the reminder for state-required safety/emissions inspection. It's annoying in most states (other than NY and a few other NE states) where you don't have annual/bi-annual inspections That icon is used for several serious problems that require service, but they all come with additional text AFAIK. I wouldn't totally ignore it.
Like mentioned above it that symbol is for the vehicle check service. Basically a look all over the vehicle to make sure it is road worthy. I would ignore for now and next service just have it reset.
I have a 2008 135 and will soon need brakes. I would like less residue but original performance otherwise. Recommendations? Also can I just replace pads vs $800 per axle dealer cost?
See if there are axxis or PBR ceramic pads available for your model. You can measure your rotors with a micrometer & see if they're still in spec. If they still have life left before getting to the minimum rotor thickness, then going forward you'd just have to check them & do some monitoring as time goes on. It's certainly possible to swap out pads yourself if you're so inclined & wish to tackle it - of course, you'd have to get/borrow/buy what all tools are needed to do it, & follow safe & common sense jacking/securing procedures, etc. Relatively speaking, brakes aren't hard to work on, but any car project isn't worth endangering oneself due to lack of tools, knowledge, safety, or common sense. If your pad min. thickness sensor isn't lighting on your dash, or otherwise damaged, it's probably ok to re-use, just check it's condition, make sure the wire insulation isn't cracked/damaged.
The rotors will have the minimum spec stamped on them. If they measure below that they need to be replaced. Like mentioned above ceramic will help with residue and you won't notice braking difference with every day driving.
