Does it do it while the engine is running? Do you have hydraulic fluid for the ASR? A separate resevoir? I had a 140 that would sit and click while idle, it was a consistent click perfectly timed coming from the pump while at idle. It turned out to be low on hyd fluid for the ASR differential. Just a thought maybe that could be your problem. I also noticed on mine the hydraulic lines that went down the drivers side of the car were hot, really hotter than usual, because when I heard the clicking I looked under the car and felt to see if I could feel the clicking. Check that out, maybe change the brake fluid and the ASR fluid. The ASR works through the pulsing of the brakes and pressure through the differential. Good luck!
