E66 Help

[MarkEg1505]

New to the forum -- just bought an E66 3.0d auto on an 06 plate. Absolutely immaculate inside out. I have a couple of questions:

1. It has a spare so I'm guessing it's not on run flats. However, I occasionally get the flat tyre warning light on, then goes off again after a while. Any solution there?

2.Should I get the swirl flaps removed?

3. They say the auto box is sealed for life, should I do a trans fluid and filter change though? Car has 100K on the clock

4. Slight wheel wobble when braking at 50-60MPH. Could that be tracking/ balance? Or more likely rotors/ front wishbone bushes?


Any assistance very much appreciated

1. Spare tyre means no run flats - gives the car it's critically acclaimed comfort. Tyre pressure is calculated by loads on certain parts of the suspension. A quick reset through the iDrive should sort it out.
2. Yes. Swirl flaps are much more troublesome on earlier M57 engines, less troublesome on the later ones.
3. Change the fluid. It's needed.
4. Wobble when braking may be suspension/tracking/brakes. Have you put new tyres on? Has it been aligned? When is it due brakes?

Many thanks for this. I'll do as you suggest re: trans and swirlflaps. I'll also do alignment and wheel balance first. If it was suspension related, wouldn't I be getting other symptoms also?

Yes you would to be honest, looking at it now I think it's more down to the brakes. One calliper could be sticking, pads not fitted properly, issues in the lines?

Thanks for the input. Inspection reveals a leaking bush on the driver's side of what they are calling the 'brake reaction arm'. All discs/ tyres/ pads etc are fine, so would this seem to be the most obvious cause.

And, is it likely to be an expensive fix?
