Anyone out there experienced this? My 1991 9000S 2.3 Turbo has developed a fault. The history is this: May be unrelated, but heater hose recently blew, pouring steam all over engine. Luckily I stopped before any engine damage occurred! Replaced hose and all seemed to be OK, until, whilst sat in slow moving traffic, TCS warning light came on and engine stopped. Managed to restart car in 'limp-home' mode, very difficult to drive like this. Realised that I hadn't clipped some wiring back to a bracket after doing the hose and thought the problem might be 'heat-soak' through the wiring. Clipped wiring back up, and all seemed to be well, until 2 days later, when sat in same traffic jam, same fault occurs again!! I can drive the car as fast as I want, uphill etc and this fault never occurs. But after a few minutes of sitting in slow moving or stationary traffic, the fault comes back. If I leave the Air-Con on, so that the fan runs all the time, the fault doesn't seem to happen as quickly. If I disconnect the master cylinder electrically the system seems to reset until the next time it gets hot. I'm becoming more & more certain that this fault is heat related, but why??? Does anyone know what equipment you need to 'interrogate' the system for fault finding? Please has anyone ever come across anything like this? The fault renders the car almost un-driveable. Many Thanks Pete Gloucester UK '91 9000S 2.3 Turbo
