M-Sport Steering Box questions...

[MTechnik540i]

There were 2 Steering boxes ZF Manufactured for the 540. One was servotronic and the other wasnt. I had the non-servotronic Steering box. I bought the Servotronic Reman Steering Box and fitted it onto my build date 11/93 e34 540 - and it works fine. It is the same box - it has the electronics built into it to recieve input from the Servotronic system - but since I have no Servotronic - It just operates as the normal Steering box.

The 540 Steering boxes in the US were different than the US Spec 535/535 Rack and Pinion steering boxes. BMW had to use the different Box due to the fact that the rack and pinion boxes would not clear the V-8 motors. Hope this helps if at all - JT

Yeah, I read that in your other thread. Still waiting to hear back from that ebay seller you listed, to see if that's one of his ~$400 remanufactured units are a possibility.

Alright, So I ordered the part from the part# that you listed and received this...Wasn't exactly what I was expecting to find...



Any ideas?

Wow, me either. I wonder if that's a mis-pick. It looks like it has harness connectors for the servotronic brain on one end, who knows what's on the other side. Have no idea why it's marked as a tool. I'll check the P/N again on tuesday.

Yeah, that was my first thought when I saw it.

I'm puzzled why it's called a 'Tool' also.

May get ahold of my ZF contact tomorrow, see if he might be able to assist me.
