Another MOT pass - no advisories! Annoyingly and very strangely the car drove home somewhat erratically following said test. By which I mean the classic steering wheel shimmy under light braking. Coincidence???? It certainly took the gloss off the pass. As luck would have it I dropped the car off this morning anyway for the door replacement and 4 wheel refurb and mentioned this as I thought a proper balance after the refurb might sort it (the only thing I could think might have caused the car to drive ok pre MOT and not OK after other than inspector error was a wheel balancer dropping off). The mechanic looked at front discs and said they appeared very worn and thought them the likely culprit. I drive says they have 10000s of miles left. Obviously a visual inspection will always trump a computer but I wondered whether others have had to replace discs or pads out of sync with what the I drive tells you?
Yes. For some reason, E6x autos seem to like to warp brake discs (admittedly depending on how you drive). I replaced mine last year for this, the same shimmy came back over winter, local garage skimmed them and took 0.2mm off and it's now great again. If you can get them skimmed do, it's a lot cheaper than new discs...Shirt587 said:

What does seem strange to me is that the car was fine when I drove it to the MOT and then exhibited the problems after the MOT. Even stranger, the MOT tester actually commented on the rusty discs although didn't feel the need to note it as an advisory. As soon as he had commented and I drove the car away from the garage I noticed the problem. This would make sense if it was a scam and he wanted to charge me to replace the discs but as he had just passed the car it really is a strange coincidence.
I suppose it is possible that some extreme in MOT test could have exacerbated the problem. I also had to drive up and down a pretty hefty kerb to get into the MOT bay and wondered whether the clunk, clunk could have had any effect!
It is hard to say whether the discs are pitted or warped as until yesterday I though they were fine - I guess they are rusty (I can see that by looking at them) and so probably more likely to be pitted than warped.
I take the point re skimming, I will ask the garage. As all 4 wheels are off anyway, shouldn't really be a big job should it.

There are many causes of wheel wobble:
Tyre - age / deformed / egged / bubble / flat spotted
Disc - as discussed
Wheel / Alloy - buckled / out of balance / wheel weight knocked off
Sometimes this problem can be exaggerated by worn bushes. The wheel wobble problem is well documented for the e39. Is the e60/61 immune from this?

312 delivered for genuine parts from cotswold bmw via forum.bmw5.co.uk, then an Indy should charge about an hour maybe hour and a half. So 450 all in?
More reasonable - I think I will decline the work and just look elsewhere. The quote included £100 for labour so that means the parts cost is £550. I wonder whether they have mistakenly looked for M5 parts that is seriously the only thing I can think of...jboy72 said:

No I think that's the proper full price of OEM discs, pads and wear thingies. The front discs are huge. My indy was quoting the same but they are happy to fit parts supplied by myself.GSF will sell me Zimmermann discs for £90 each (the larger 36mm version) and a set of brembo pads for £60.
Coincidentally, there is a GSF next to the garage. I feel a little embarrassed about asking them to pop next door to pick up the parts for half the price they said they would cost (they quoted £450 for "pattern" parts) but not really sure why I should be?!

At £240 for them discs and pads, plus wear sensor? £10???
I'd rather pay the extra to £312 and have the genuine parts.. At least you won't have to put up with rusty hubs as the genuine discs don't rust there.
They must be some sort of alloy, mine look to have these rivet type things around the hub. Certainly look the part!

Good point both, there isn't much in it is there. I did go on the Cotswold BMW site but it was not very easily navigable. I will make an enquiry...I'd rather pay the extra to £312 and have the genuine parts.. At least you won't have to put up with rusty hubs as the genuine discs don't rust there.

I simply couldn't believe my luck this morning. Was greeted by the attached sight, well actually it was quite a lot worse - this is post t-cut. What sort of a selfish xxxx does that and then absconds from the scene? Happy xxxxxxx Valentine's Day you xxxx. I'm in a quandary now though. I just don't know whether to sort it or wear the wound with pride? Gaaargh.
Looking a little better now as are the wheels!
