Leaky Diff, something warranty would cover?

Leaky Diff, something warranty would cover?

As far as I am aware the diff is generally not covered under warranty as the stealers usually claim it's failed through use.

That said if your diff is OEM and was fitted by an BMW dealer or BMW Indie/specialist the part is covered by 2 years parts and labour warranty.

I know this is the case as I've just had a brand new BMW diff fail after 10 miles!!!! Subject to the stealers assessing the failure they'll be fitting a replacement Free of Charge.

Leaky Diff, something warranty would cover?

I have had a new diff on warranty before, also I know of a person on here has had seals replaced on warranty, I don't think mileage would be a factor as it has failed.

I had a new diff on warranty :)
There were no questions asked, in fact I didn't even think anything was wrong but the dealer spotted something when servicing.

I have had the diff seals done last year on warranty @ 65k miles

Warranty will sort this with new seals or a new diff if its noisy :whistle:

I've had my whole diff replaced under BMW / Mondial Warranty few years ago when it became quite clunky & loose, thanks to Garteh :beer:
Make sure if has the new, improved oil in it as my replacement arrived filled with the old stuff and we had to ask BMW warranty to pay for the new improved diff oil, which they eventually did :thumbs:

It's only covered if you have the full warranty. The drivetrain and other mid-cost option don't cover any seals. No need to ask me how I know this :banghead:

Added to this we all know the dealers that are/were proactive when processing claims: Elms, Murketts of old, to name but 2.

Some no mark stealers are useless when communicating with Mondial.

I had a new diff under warranty on my standard M3.

How much is comp costing you out of interest?

Bit of a thread resurrection but thought rather this than starting a new one.

Mine was in for an oil service last week and while in they noticed some oil around the input shaft area. I can only assume the seals have gone there but of course, they want to book the car in for diagnosis before assessing whether they'll cover it under warranty or not...

Typical now it's summer and the car might be off the right for a week or two... I should have left it in while I'm offshore for a few weeks now.

my diff seals have just been done under warranty

Did they replace just the seals? When an output shaft bearing collapsed on mine previously, they replaced the whole diff as apparently BMW Warranty wouldn't allow them to replace parts on the diff. I'd be happy enough with just the seals replaced.

as far as I know , just the rear seals. Whilst the diff was out though they found I needed to replace the rear solid brake lines that run over the diff and they werent covered by the warranty :(

[sailorbaz]

The brake lines couldn't have been expensive though were they? Might ask for replacements while the diff is out anyway... maybe they have to take the fuel tank out too?? :banghead:

[azrael]

They refused mine, although I think that was just the dealer couldn't be arsed as I've seen others have been done.

I got Simpson Motorsport to do it in the end

approx £300 just for the pipes !!

Along with a new oil cooler pipe, new rear discs etc etc it wasnt a cheap visit to the dealers
