Hi Group:

Any weirdness I need to know about the cooling system on an S4? I'm going to do a coolant flush/change, and while I've done it countless times on earlier 105/115's, I've never had the pleasure on a Motronic Spider. TIA for any pointers.

IAP's tech tip - cooling system fill/bleed

The S4 Spider (Motronic engine) doesn't have the bleed screw on top of the throttle body. I believe it is 'self bleeding' at that point.

Thanks, Eric. That's what I suspected with a header tank up high on the firewall of the S4.
