Subframe

Had mine checked at Elm's with Gareth yesterday.

Warranty work submitted, now just waiting for BMW approval (fingers crossed).

How bad was yours??


Steve

[northernjim]

Does anyone know is the replacement section an updated part that will stop any issue in the future??


Steve

Yes it is - so I have been told

The replacement floor is exactly the same as the one already on your car - it was updated in and around 2003 just before the M3 CSL production started.

that's not what I have found.....

old part number was - 41 00 7 030 266 weight 4.8kg

new part number - 41 11 7 000 246 weight 21.3kg

I cannot find the website that told me the date, but it was around 2005 0r 2006 when this new part came into use

[Steve B]

Must be made of gold..... 16.5kgs heavier...:smt104

I would appreciate if the guys that had the subframe replaced, send me a pm with their VIN numbers.

Jim, where are you getting these weight figures from mate ? They look very odd :smt017
When my Cecil got fixed last month @ Elms I spoke to the mechanic who actually does all the repair work and worked on mine. I asked him if the replacement boot floor was at all different to the old one and why the different part number. According to him the replacement boot floor is the same as the old one, it's just the part number that has been super-seeded in & around '05/ '06, a common BMW practice apparently.
What actually fixes any future chassis problems is the structural foam that's injected once the new metal work is welded back in place, which stops the flexing and any future rear chassis/boot floor cracks. :smt023

I suppose U have a few extra years on your CS no L before the 10 year warranty is out but have you had yours checked yet ? :whistle:

Have a look here Matt

I know the weights seem to be way different but it's on the tinterweb so it must be true right?????


Reddish Motorsport have told me that it is a different part that they replace it with......?????? So I have no idea what right and what wrong:clown: some things never change eh! :beer:


Mine is in warranty until 2018, and the way I drive it won't break until 2028 :gayfight::hahaha:

I'd go with what the man @ BMW said. After all, he cut out the old bit and welded in the new bit a few times now so would have/should have noticed any differences, if there were any

:hahaha: :hahaha: :hahaha: get it foam injected, U big girl :gayfight:

It is exactly the same part, made exactly the same way.

You are looking at the incorrect item numbering - look at item "1" and item "16" the weight is exactly the same at 21.325kg


Repair part, insert, rear axle support41 11 7 000 246

Only in conjunction with Pos. 23

When installing in M3 or M3CSL Remove absorber mass
121.325 kg / 47.014 lb


The update was in mid or late 2002 (I can't recall now) but it was just before the CSL came out.

All the new ETKs online now don't show the pre 2002 part from what I can see.

The updated part number is just a supercession - BMW does it all the time to show whether the part is a production or reproduction part - nothing has changed.

Get the injection - it is what stops the flex in that triple layered floor.

beat me to it :-d

Is this injected in once you have a new floor fitted or is it just left to crack again??

Steve

Yes the newer repairs now include injection.

[shimmy]

Yes the newer repairs now include injection.

I think original repair also included injection. Mine was done early 2010 and TIS sheet then had injection after new floor, and mine had new floor and injection.
