Greetings CS world Although I only have a 2002tii in the garage, I have chanced across an item which may be of interest to a CS owner. It is a Bosch Diagnostic tester which I believe to be for all 6 cylinder injected models. My tame mech, ex BMW in the 70's thinks it may have been called a "228 Tester", however his memory may be a bit suspect. The unit has no distinguishing marks other than a serial no on the back. It plugs into the underseat comp through a grey multipin inline socket, and then enables you to run a complete diagnostic series to set up injectors, etc. I would be grateful if anyone could provide any further info on this.
