has anyone here retro fitted or heard of anyone fitting the active cruise control set up into their m5? or does anyone know if you could buy this as an option? been looking around and i cant seem to find much info on the subject. i already have pdc sensors in the front and i can see the picture in the cluster for it. so now im wondering what it would take to make it all work. i do know that there will be some coding involved but what hardware is need?

ACC uses a radar sensor, not our PDC's. It would be a very costly upgrade.

 

[mattmartindrift]

you would need the radar sensors and module coding at the very least.

It would be neat....but GL sourcing all the parts. Coding will be a pain too, as it wasnt offered in the US.

Can't say I'd trust the PDC sensors for that anyway. oohhh:

I've never seen any part numbers for this system, and as far as I know it was only ever offered on the 7 series E38 and not the E39. The symbol on the dash is only there because the cluster unit uses common parts with the E38.

However, if you find the parts I'd be interested to see how you get on!

 

[RichardP]

Having said that, here is the sensor you need for it!

ACC-Sensor BMW 7' E38, 750i (M73N)

A snip at $2660!

well, the E38 shared cruise control and engines/DMEs with the 540; so maybe i'm in luck!? probably not, I think I would need a 99+ 540.

Either way, the E38 shares most modules/computers with the E39; so, it should be doable.


who wants to buy me the sensor and I can give it a go!?

 

[zarnd]

Good luck, but don't think it is economical to do so.

cheers

 

[RichardP]

From the little I can find you need to have the correct steering wheel and cluster together with a few other things.

I have also attached the document as that site occasionally goes down.

Matt,

It seems that insofar as the E38 ACC is concerned, it is assumed that the vehicle is equipped with an automatic transmission. It would be quite a retrofit to say the least.

I would not TRUST a ACC retro fitted in the M, if it was not there from the beginning.

why? would you really pay so little attention to the road that it would be that much of a concern?

Why would one even need ACC if they payed attention to the road

if you do not know when to or can't disengage CC while using it maybe you shouldn't be driving.

 

[RichardP]

From my point of view, the only reason that I ever use CC is to help me drive more slowly!

 

[mailman]

This ACC is actually quite "interesting", seen how it works in my friends E61 550.
But no, really dont see why bother to spend tons of money to retrofit that to the E39...

 

[n0thingface]

wow thats a crazy amount of response in a short time any way i just figured it would be one of those cool factor things dont really need it and though well if all the parts from a e38 would work how hard would it be to make work on our e39? the biggest concern would be the fact that its seems to only work with auto e38.

+1 why would you ever want ACC, normal cruise control is just fine

All you'd need is the EGS and a the pinout for it.
