X5M AUC, rear disc thickness

[contractor]

Hiya,

Could do with some help just to make sure I'm not going mad. I'm talking to a BMW dealer about an AUC F85 X5M and I've been sent the condition sheet.

According to realoem the rear discs are 24mm think when new, with a min of 22.4mm.

https://www.realoem.com/bmw/enUS/part?id=KT62-EUR-...

The AUC sheet sent to me says rear min 30.4, act 31.2 which makes no sense. It also lists front min as 34.4 min, act 34.8 which is OK so I know that adds up.

I asked the sales guy but he could only say that he's not a tech so no idea...

They also reckon it came with runflats. I didn't think any M came with RFT?

Any ideas?

Thx

NO real M car has Run-flats, the tech stuff no idea.

As far as the brake discs it wouldn't be the first time there's an error in the BMW parts system.

thanks for replying but an X5M a real M, (S designated engine) and those tyres are not run flats.

I've just looked at an F85 X5M and was also told it does not have runflats (on 21" if that makes any difference).
He also said the disks should be changed after every 2 sets of pads...hmmm.

Slightly thread hijacking - I was also told the comfort access key stops tramsitting after 'a while' to stop the thefts of comfort access cars.
It's a 2017 car, is that right?

i thought comfort key motion detect was only on Gxx cars? There was talk about a retro scheme for Fxx but no idea if it happened.

NOPE the car is to early, it does not do that.

JM is sport on, only way to retro fix comfort access is to order brand new keys which have a motion sensor in them.... obviously not an inexpensive thing to do but cheaper than losing a car if not garaged.

I've had a BMW dealer intentionally falsify brake disc thickness on M car before.

Be sure to double check and not accept their measurements and stated minimum thickness as correct.

Same here; my M5 came with new pads and knackered discs (well below the wear limit). I kicked up a fuss and they had to pay my local dealer to replace the discs and the pads as well as they had worn to the old discs.

I caught the dealer out prior to purchase. They then asked me to make a contribution to the cost if I wanted new discs. I laughed and asked for my deposit back.

They argued that brake thickness was not an MOT issue. The brakes were fine. They ignored the AUC report to say the discs were well past their minimum. They edited the report to make it look as if the minimum allowable thickness was thinner than the mechanic had written.

The next again week I got a call back that they would change the discs if I went ahead with the deal. The issue was the car had been discounted in that time. The difference in price was now the cost of the new brakes. They wouldn't honour the new selling price and change the brakes.

Update

The dealer has rechecked and has now said that "due to a typo it was recorded wrong". Rears are well within spec as they are currently on 23.4. Not sure how you can mis-type 23.4/22.4 as 31.2/30.4 but anyhow...

I also asked how come the pads all say 5.0mm yet the miles remaining for the fronts was 36,000 and rear was 9,000. Turns out the front pads were swapped out, even though this has not been recorded on the in-car service history. If they were all 5.0mm, why swap at all, and why only do one set?

Finally they've also said that they have remeasured the front discs and they are at 34.4mm (which is the min) and not the previously recorded 34.8mm, but as the pads don't need doing they don't need to do the discs so are trying to use it as a negotiation tactic. Spot the flaw in their logic here...

I've gone back with final offer/take it or leave it as i'm tired with all the pissing around.

Good luck with your purchase contractor and thanks for your help in the other site/thread :-)

[contractor]

so the dealer has come good and it's all systems go. Sometimes a face-to-face discussion is what's needed as doing it online/email/phone isn't optimal...

[margerison]

Ooh, which one is it?!
