Two huge bangs on the M6 today, southbound before the Sandbach services, the road surface changes from tarmac to red concrete, too many potholes on that stretch for my liking, hit one unseen one, shocking noise, then just after the Cheltenham junction just after the 50 mph restriction ends, just started to open up the throttle and a gap appeared across the whole of the lane were in, no time to slow, flaming heck, I thought both front alloys had had it. It was the loudest bang I have heard driving a car. No, the car just sailed on, while my ticker was racing.

Had a good look at them when I got back, all seems well.

What a relief.

Hope he had his suspension & chassis checked out after that!

Passed MOT with no advisories so my 326's have been good for 6 months on Michelin PSS.

I'm sure the vast majority of their work is good!

Something like the wheel problem comes about by getting the form v function balance wrong and in all probability the wheels aren't designed or manufactured by BMW !

The same goes for the problematic rear lamps, who and where are they manufactured?

Car manufactures are really just assembly plants in these days!

It's irrelevant who they subcontract to - BMW are totally responsible to you for the design and manufacture of the car and all its components and subassemblies whether BMW is the actual manufacturer of the part or not.

Bear in mind that by sticking a BMW part number on the packaging of a wheel or light assembly they also add a whacking great margin (unlikely to be less than 100% and in some cases possibly more like 200% or 300%).

Eurocarparts were selling rear light assemblies for £135 - chances are these are from the same third party supplier that BMW use. How much do BMW charge for this assembly? We know the BMW ones have a problem - if the £135 ones have the same problem then BMW are cynically charging over and above for the same component without ensuring that the premium you pay gets you the quality you think you're paying for. Perhaps worse for BMW - if it transpires the £135 part doesn't have an issue?

I realise who has the responsibility - I just wondered who manufactured the components.
I've had some experience of the process and my guess is that like most things in mass production, they are built to a price then the manufacturer will max his profit by trimming his costs but keeping within specification.

I have had experience of parts being manufactured, looking fit for purpose and subsequently failing - all because of suspect manufacturing techniques to save money.

Interesting thread and would have thought using a non run flat tyre can only help but recently
I found a crack on one of the rear wheels on my E46 330, 18" MV2's, I can safely say i'd not hit
any potholes etc so is it a long going manufacturing problem.

Are all BMW's wheels made at the same place/company ?

Not sure i'm prepared to buy a car that has this as an on going problem especially if BMW aren't dealing
with it

Changed to not run flats last year and upped the rear tyre profile by 5.

I have been ramming my car down potholes without any thought, and not had a single crack since
