I had a hard time getting out of a field in reverse, but no problem forward, and it got me thinking that awd doesen't work in reverse. The halidex is a clutch/coulper and maybe it doesen't work backwords?? Am I completely wrong?

Any comments?

 

good question

I can't say I ever remember having trouble backing around in the winter, I'd assume it works in reverse, but I've never put that much thought to it.

 

i don't see why it doesn't, but you never know. ANYONE?

 

its probably due to the fact that the power distribution isnt 50/50... more 80/20 i believe... maybe thats it? not sure

 

This link makes it sound like it doesn't matter if you're in reverse.
However it's not clearly stated. Also I'm unsure if this is the same generation of Haldex system we have in our cars.

Still a good read...

Next time someone has their car jacked up....

 

yeah it does work in reverse!!!
i was drifting up in the mountains last spring, when i first got my a4, and slid into a ditch, i only had traction to one wheel (Front 2 were in the ditch and right rear was about a foor off the ground) and still got out with no problem! it was pretty amazing actually!!

 

A4 has the torsion AWD, not haldex, its permanent AWD, haldex isnt.

 

AWD works in reverse. Verifyed in the audi tt the complete story book.
