Any ideas on a Fail-Safe mode amber warning light coming on? Comes on every 5-10 minutes or so after about 20 minutes driving. comdes on for a few seconds and then -off again!
Nothing seems to be wrong with the car (temperature guage is ok)but it is a little irritating....
Any ideas?

Our vehicle has started 'Fail-safe' after 60,000kms and Jaguar dont care.
The problem is attributed to the throttle body assy.($4,500 AUS) and it is intermittent. We went away for a week (1500kms) and it was perfect, came home and went intoF/S 6 times in 10kms. We cant drive anywhere now and cannot purchase a used T/Body.
I would buy a new one but am scared what the next costs will be to keep it running.
Have also replaced, watertank, many faulty hoses, by-pass tube (the small spigot becomes brittle and snaps off), heater control valve Etc.
It could also be due to throttle position sensor.

I would get the codes ran. As far as the throttle body problem; are used throttle bodies that hard to come by? You could probably find a good used one at a local salvage yard. That way you won't feel like you're selling an arm and a leg to get one and maintain it.

Similar problem. I replaced the throttle body assembly so it doesn't go into limp mode anymore. Now my failsafe comes on as an engine fault but the car is driveable although it surges a little. I played with the mass air flowmeter but that doesn't seem to be the issue. The idea of a throttle position sensor is my next try. Any other ideas?

I have 2000 s type jaguar. it was runing fine until 85000 miles all the sudden Fail-Safe Engine light comesup I dont know what to do with that I ask couple people what i can do aboutit nobody no much so i google got answer saying your T/Body get dirty which stop the airflow going to the engine that cost fail-safe engine. To solve this problem just take out your T/Body and cleanit up that will solve your problems. So took my T/Body and cleanup realy good and put the whole thing together since that Fail-safe engine light did not comeback so far.
