cruise

Having bought a reconditioned cruise control amplifier unit for an R107 (p/n 0035450732) I am the proud owner of my old broken unit. Does anyone know who can rebuild my own unit so that I have a spare? Resoldering it myself seems a bit pointless if I don't have the facility to test it.

My 1997 C Class 1.8 estate. The ABS dashbd warning light has come on and at the same time the Cruise Control went inoperative. I suspect the 2 are related as I googled another person with the same problem (but sadly I couldn't find the resolution). Can anyone help? I don't have any...
