335xiRT1 · 05-26-2009, 09:22 PM

Blew the center diff. This past weekend BMW replacing it no questions asked. Should have it back in a couple of days. Anyone else here have done that? I thought these cars could take a little abuse geuss not.

I was merging onto a highway on one of those cloverleaf turn around roads doing about 60mph in 2nd gear and when i got to the bottom of it to merge on the highway i smashed it into 3rd and it just went. It was late no one was on the roads at the time. I dont drive my car lightly, its a lease it goes back in 3 months.

Another reason NOT to purchase a lease return ...... CPO'd or not.

You weren't kidding with the 'smashing' into gear. I bet you were moving the shift lever as quickly as possible, releasing the clutch and getting back on the throttle as quickly as possible too.

in RWD car wheel spin would save the gearbox but in AWD car all of the drivetrain shock gets absorbed by the gearbox

i suspect the gearbox can take 'a little' abuse, but you were giving it A LOT of abuse, so it broke.

I guess that's part of what you pay for with BMW. in EVO/STi/WRX word it would have been a huge back and forth because the dealer would almost certainly have called abuse and tried to deny the warranty claim

335xiRT1 · 05-26-2009, 10:44 PM

I wouldn't buy someones car after there lease is up. Cause theres plenty of other people out there just like me.
I was shifting the car hard at the time.

ya because you know the 24" spinners really strain the diff lol

Seems like i am the minority here, but i'm sure the guy knows how to drive(his lease is up in a few months so he has ALOT of expierence with it.) How much drivetrain shock can come from a 2nd-3rd gear shift, regardless of how fast it was? I would think the car had a faulty diff from the factory or something else wrong with it.

+1 the car should not experience that much stress when shifting from 2nd to 3rd... I'm lost as to why it would happen other than the diff being faulty

A LOT of shock can come from 2nd to 3rd gear shift if you are sidestepping the clutch at WOT

here's a good post that discusses "shock load" (you have to wade through some newbie posts to glean the tech)

EDIT: OP did you remove the clutch delay valve?

335xiRT1 · 05-27-2009, 04:38 PM

I'm no noob driver owned a STi previously. I'm sure the diff. is somewhat faulty. The car has 21,000 miles on it.

Priority 1 · 05-27-2009, 10:12 PM

isn't the clutch delay valve supposed to save transmission components from shock by more gradually engaging gears than we want?

TwinTurboXI · 05-28-2009, 10:46 AM

OP, update us on what the dealer says.

335xiRT1 · 05-28-2009, 11:29 AM

Dealer go new diff. in today should have car back friday, all covered under warranty

nomile · 06-01-2009, 01:48 PM

I'd also like to know what size tires you're using on this xi. Front and back please.
