How do I tell if I have an LSD

**Jay 535i** · 03-03-2006, 12:06 PM

I mean really tell for certain, rather than putting one wheel on ice and interpreting the results?

My VIN is WBAHD230XLBF63449.

look at the tag or raise the rear wheels, leave it in gear and spin 1 wheel...if the other side spins in reverse you dont have LSD.

What tag is that, Jeff?

Thanks.

Probably the tag on the LSD itself... It should have some sort of a letter next to a number, it would be the only letter there so I dont think I need to look up exactly what it is...

It should read something like: 3.46x and "x" is either nothing or a letter --> if its a letter, it is a limited slip, if X doesnt exist then its not an LSD.

Thanks, Artem. I'll have a look the next time the car's on the lift.

One more day, baby

got heated seats? if so, you prolly have an LSD. One way, is to turn frmo a stop and floor it...if the inside wheel lights up you dont have one. If both wheels light uip and the back end kicks out, you have LSD.

I do have heated seats, and headlamp washers.

I've done the test you mention and I'm pretty sure the results indicated an LSD, but with the slushbox I don't trust myself to tell. I'm gonna look at the tag.

Unless, that is, we can be certain that heated seats + headlamp washers = LSD.

Thanks, though.

I know those rules apply to the 5-spd, not sure about the automatic though.
