Default Subframe Cracks - What happened with you?

I've just been on the phone with Hungerford BMW and they've had this problem with several cars. they need to inspect themselves and document the edvidence, check the mileage and take photos so they create a case file for the repair.

does this sound the same as anyone else getting this done.

Sound about right as some dealers are claiming they are unfamiliar with the issue at all

Spot on, BMWGB will want photos and more photos and will ask about mods to suspension etc before agreeing to goodwill on the crack repairs

When I get round to it I'm going to get the foam and inject it as they would. That's if my floor hasn't fallen apart by then.

Prevention is better than cure and that is all they (BMW) would do at first signs of a crack (less than 20mm).

Hopefully that way my car won't ever need a new floor pan. The new floor they put in is no stronger than the old one, but it is reinforced with the foam to prevent it cracking again.
So an uncracked old floor with the foam treatment should be as good as would be provided by the repair anyway.

For belt and braces I'm also thinking of adding the Turner reinforcement kit, epoxy'd on and not welded. So far I'm only thinking about that bit though.

good stuff. I'm getting the RTABs this week and I've managed to get a loan of some springs to get the repair done.

Awsome thread guyz! I'm preparing myself for the worst as I suspect my subframe is cracked.

This is really helpful! If it is cracked I'll be going to loughton or Enfield BMW to get it fixed, anyone had them repair this problem?

nice one.

just for the record, I have 76k on the car, registered in Jun 02 and it's going in to them standard. There is also only one 3 inch hairline crack in the rear left of the car.

so if this gets sorted by them and you're in the same range as me you know you're laughing.

The BMW dealer in Perth said to me that they haven't had any in with a cracked subframe yet......The service manager wasn't in at the time tho,so i'll go back and see him at a later date to see what he's sayin on the matter.

Has anyone got detailed pic of where this occurs or what I'm looking for as I have had a look but can't seem to see anything but would have more hope if I knew what I was looking for!

This is a really good idea, anyone worried about their floor pan cracking (which should be everyone) should do this!!

Just drive yours hard round corners to make the crack bigger so they replace it!

The dealer took photos of mine, confirmed it was over 20mm, checked only for stamps in the book, and ignored the AP Racing kit.

Best way to check for cracks is to get it to a good indy first (that knows what they're doing, like AL and the like). Don't get BMW to check first hand as they can sometimes charge you for the inspection.

See the more i hear this the more I think "Why am I putting it back to standard?" I recon if i call and ask a hypothetical question it'll drop me in the siht, if I risk it and take the car as is then I'll get mugged off.

My thinking is like most so i want to do everything i can to eliminate the likelyhood of them saying no to the repair. That said, it would be so much less work if they would take the car as is. lol

The inconvenience of putting the car back to standard is better than the inconvenince of having your wallet rinsed for approx 5k!

It clearly states in the tech bulletin, 'No aftermarket/non BMW approved suspension'

They will take loads of pictures during the repair process.
