My X5 is not a diesel, yet my tips are always really dirty. I have to scrub this residue off once a week. Is this normal for the rest of you people ??

I've got a '11 35d. Zero soot at 1200 miles.

Yes. Ours will get like that after a few weeks but it wipes right off and shines up like new. I keep the tips polished & waxed so I'm sure that helps.

I'll throw a few coats of wax on it. See if that help remove it easier.

NORMAL? i think you might be confused my brother, scrubbing your tailpipes weekly is far from normal. to each their own i suppose. :rofl:

i remember this guy on one of the Z06 forums that would put his car on jackstands weekly so he could clean, wash & wax the fender wells and under-carriage.

i suppose if you gots that kinda time..............

don't do that. wax isn't made for the chrome tips, nor will it handle the heat of the exhaust gases.

you can try some chrome polish, which i typically apply once every month or so.

and yes, my tips on the 4.8 gets like that. but then again, i have a lead foot and avg. 11 mpg. :(

It's normal, for crying out loud this is a performance car that should have some dirty spots and battle scars. Leave the garage beauty queen title for the GT.

Hahaha. That might have something to do with it. I like to hear it roar ;-)

I've put only 700 miles on my X5 and my tips look the same!

My X5 is far from a garage queen. But it is spotless 98% of the time. Driving a dirty vehicle bothers me. I go through it meticulously once a week, and wipe it down after any prolonged ride. I'll post pics of my GT one day. You can eat off the Brembo's and wheels on that one :)
