Well, having only quite recently fitted an FBH to my facelift 75, and everything working great for a few weeks it would seem to have developed a problem.
I have a temp gauge fitted to my car so I can see what's happening quite easily. Normally when the FBH fires up I can see the temp climbs quite quickly up to about 75 Deg, which is of course where the FBH would back off. I noticed the other day that the temp climbed quickly to about 40 Deg then slow right down. I figured the FBH had turned off for some reason, maybe the outside temp had gone up a little.
Anyway, it was cold outside this morning, so I thought I would try it again. The same thing happened, it was obviously working up to about 60 deg then turned off. I pulled up and let the car tick over for a few minutes. The temp gauge started to drop a few degrees, so I opened the bonnet and felt the FBH exhaust. It was just warm, and the FBH had turned off.
I went home and let the car cool down for about an hour. By this time the outside temp had gone up so I wired +12 to pin one (it's an early 66232C) and set my stopwatch going. It made a few noises, started to get warm (exhaust pipe) and ran for a total of about 3 mins before totally shutting down. I removed the fuse to reset and tried again, same thing! total shutdown at about 3 mins.
Does anyone know what the problem could be? The most annoying thing is I have just ordered a GSM unit to trigger it by text.
