BMW Sub-frame Defect Class Action Lawsuit

[DazBlackCSL]

Agreed. I get mine checked by a specialist on a regular basis and I'd advise anyone else to do the same. Use your trusted specialist not your dealer for the inspection. When it happens go fully armed to your dealer and be prepared for a battle.

Might be worth having a word with Dazblackcsl for any pointers. I know he had a little bit of agro over it but was all done under warranty.

For sure, just remember as Nathan says to take ALL your aftermarket stuff off.
I have a good relationship with my dealer, but it was a bod from BM that had to come out to inspect it, I had removed all bar my AP's, an they approved the work.

Then when it was finished they found a few of entry passes to croft / coombe / brands etc in my glove box, for the CSL cup and then tried to wriggle out of it as they were claiming I had used the car to race :hahaha:

My dealer had to send them links to my race car / pics for the CSL cup to prove why I was there and that I was in my own race car not using my road car !! and had a real battle on email to let them release it :wanker:

even though they had originally given the go ahead, so just be firm, sensible and get on the right side of your dealer as that will help.

But any issues just drop me a PM.

Hi,

I think if you dig around enough you will
Find Cabrio owners with this problem.

The Gorilla.

So I guess they do exist, but more the exception rather than the norm unlike what you've stated and certainly I've not seen it on the M3 Cab (I might find a few if I did some digging, but certainly no where as prevalent as the Coupe, sedans and wagons).

I contacted bmw uk yesterday via e-mail to the tune of " I am looking into purchasing e46 m3 csl and research has indicated a common problem in this model RANGE." I said that the problem is concerning the rear subframe etc etc and that the U.S has seemingly sorted the problem with a recall inspection/repair via a class action lawsuit and asked what the situation is here in the uk concerning the matter.

Just to test the water......

No reply as yet........

Dear Mr Thomas Jnr

Thank you for your online enquiry in relation to your research into the E46 M3.

I can confirm that BMW Group UK have not released a national recall in relation to the subframe of the E46 M3. If a customer experiences an issue with their subframe and it is brought to the attention of a BMW Approved Dealership, following inspection, should a manufacturing defect be identified, the dealership can contact us directly to determine if financial support can be provided towards the repair.

Taking this into account, I regret that I am unable to provide you any conclusive information as each case is addressed on its own merits, following the diagnostic results from the inspecting dealership.

If you have any further queries, please do not hesitate to contact me.

Yours sincerely

If I take into account what I had to do to replace my vanos, I think it should be feasible to cover it if you phone/email them every day for around 3 weeks.

So have BMW coughed up under Warranty for both your Vanos and a Subframe repair then mate?

I had problem with the Vanos, which they covered.
Not with the subframe yet (fortunately)

I see, not too bad then, what was the cost of the Vanos and is it a common occurance for a CSL? (Sorry to go slightly off topic).

Hi,

Old Thread but came across this when
looking for something else.

This is PART 1----

41 01 04 (079)
Cracks in rear axle mount (inspection on customer request)
E46 Situation:In rare cases, cracks can occur in the rear axle mount. Mostly the rear left rear axle mount is affected and in rare cases additionally the front right rear axle mount.

Cracks can occur due to extreme stress as the result of load reversal especially in driving school applications, trailer towing, extreme sport-orientated driving style as well as the installation of non-approved sport suspensions.
Affected vehicles:E46
Procedure:The rear axle mount should be inspected as follows only on the express request of the customer:

Drive vehicle on to vehicle hoist.

Important: Take particular care when lowering the rear axle to ensure that the cable for the tilt sensor is not damaged.

Undo the two rear bolts on the rear axle. Slightly lower the rear axle (approx. 10 cm).

Check the area of the rear left rear axle mount for cracks.

If cracks are found, proceed corresponding to Service Information 41 03 03 (025) .
Reimbursement:Material and labour costs incurred can be claimed through the usual warranty channels subject to current warranty terms.

Defect code 41 00 93 85 00
This defect code is not contained in the official Defect Code Catalogue but has been included in the system, thus enabling warranty claims to be processed.

Checking the rear axle support as part of order without additional repair work:Job number00 54 254 Labour6 FRUs
Warranty type1Warranty level 1 (within vehicle warranty) 2 (outside vehicle warranty) Only one of the job numbers specified above may be used for billing. Repairs are to be charged under the defect code specified in Service Information 41 03 03 (025).


And this is PART 2


41 03 03 (025)
Fractures on rear-axle support
E46 Situation:In isolated cases, fractures may occur on the rear-axle support. In most cases, the rear left support is affected. In isolated cases the front right support may also be affected.

These fractures could result in noises from the area of the rear compartment/rear axle.

Fractures may be caused by extreme loads due to strong load shifts, especially in operation in diving schools, trailer towing, an extreme sporty driving style or if non-approved sport suspension systems are installed.
Affected vehicles:E46
Manufacturing period: start of series production until February 2000
Procedure: In case of customer complaint or during inspection, check the rear-axle support for fractures and if necessary fill the area of the rear-axle support with foam. It may be necessary to fit a repair part first.

Following a major repair, the customer must be given a declaration that the vehicle has not depreciated in value as a result of the repair and that the repair was not performed as the result of an accident. ( Please refer to Enclosure 1)

Proceed as follows when examining and performing the repair:

Position vehicle on lifting platform.

Check the area of the rear left rear-axle support for fractures. Fractures may emanate from welding points
(please refer to figure 1).
If no fractures can be found, continue troubleshooting or the inspection.

Figure 1

3. In case of severe damage with fractures greater than 20 mm, continue with point 6.

If minor fractures are found, the rear axle must be lowered slightly. Continue with step 4.

4. Important!
When lowering the rear axle, take care to ensure that the cable for the tilt alarm sensor is not damaged.

- Loosen the two rear-axle bolts.

- Lower the rear axle by approx. 10 cm.

- Check the rear-axle support for fractures again.


5. If fractures smaller than 20 mm are found, continue with point 7. If larger fractures are found, continue with point 6.

6. If fractures larger than 20 mm are present:

- Install the repair part. Please refer to Repair Instructions ”Replacing rear-axle support”, RA 41 11 400.

- Adjust the rear axle

- Perform wheel alignment



Important
Photographic documentation must be compiled prior to performing the repair measures described in point 6. These photos are to be filed in the vehicle records as evidence.

7. If fractures smaller than 20 mm are found, or after the repair part has been fitted, fill the rear-axle member with foam in the area of the rear left rear-axle support.


Note:
The procedure described below is applicable to a single version. Account must be taken for vehicle-specific differences according to prevailing circumstances.


To do this, proceed as follows:

a) Remove the floor trim in the luggage compartment.

b) Prepare holes for injecting cavity foam and structuring foam as follows
(see Fig.2).



Figure 2

- Hole (1) is already present and is sealed with a plug

- Drill hole (2) in the middle between hole (1) and the corresponding hole on the right-hand side of the vehicle:
Used a 10 mm stepped drill bit.

- Hole (3) is already present and is covered by the anti-vibration liner. Expose the hole using suitable tools.




Important.
Use disposable gloves to prevent contact with the skin!

Note:
Before injecting the cavity foam, fill the hose with a trial injection.

c) Inject cavity foam into holes (2) and (3) as follows.

- Hole (2):
Insert hose approx. 120 mm (under hole (2) there is a reinforcement plate with hole already present - the hose must also be fed through this hole).

Inject cavity foam for approx. 1 second (press through once). Pull the hose approx. 3 cm back while injecting.

- Hole (3):
Inject cavity foam for approx. 0.5 second.




Note:
To make it easier to work with the structuring foam, preheat the structuring foam to approx. 60°C, e.g. in a water bath.

d) After approx. 10 minutes waiting period, injec the structuring foam from both cartridges into hole (1) using special tool 41 3 010.

Below this hole, there is another hole through which the hose must also be fed.

Verification of order: Special tool 41 3 010 was dispatched directly to the workshops by the company Cartool and can also be ordered from Cartool using the number stated.


e) Remove any protruding structuring foam from the holes and seal these with plugs.

f) Reassemble the vehicle and allow the foam to harden for 24 hours.



Important
The vehicle must not be driven during the hardening period
(may only be pushed).

Thanks for the info. Where did you find this information though Gorilla?

[The Gorilla]

Hi,

Ac427- there was a ''Class Action'' in
North Amrecia due to multipile complaints
which kicked all this off.

This information was posted by one
of those involved in that action, who
apparently had the repair works carried out.

Mr Gorilla

What's your opinion on doing this structural and cavity foam as a preventative measure? i.e. still inject it even when there are no cracks appearing?

I've seen the 'foam' in person and it's actually not a foam - rather a very hard structural epoxy that hardens without expansion - I have also seen the proceedure performed on two cars already and it isn't a large surgery per se ... and the amount of product injected into the cavity is actually quite minor.

Would like to hear your feedback on this.

Not much to it really (great DIY from the person below):

http://www.m3forum.net/m3forum/showthread.php?t=287849

[The Gorilla]

Hi,

NZ_M3- I believe your absolutely correct.

The injection of the Resin would bond the
two metal layers together making for a
lamination of the two skins around
the subframe mounts.

This would then not only spread the load
via the new ''lamination'', but it would
also absorb the 'sawing' or 'tearing'
motion across both skins around the
load points of the subframe mounts
on what was just a single skin.

There are 2 part resins that can be injected
via a hand operated resin gun,
which with a couple of small holes in the
correct places would make this a very simple
but very effective proceedure.

Also with the correct resin it would also still
allow the Sub Frame bolts to be removed
when required so it could be undertaken
with the subframe in-situ, more than likely from
above the boot floor as opposed from underneath.

Regards,

The Gorilla.
