Hey guys.

Drove to my local town today (about 15 miles) and everything was fine, mrs did 3 hrs worth of shopping and went back to car. as soon as car started i got message restricted proformance and a red warning light on dash. Had no choice but to drive home slowly.
Had a coffee then went out to see if i could see a problem, started the car and no warning or light, everything back to normal. Any ideas please

forgot to add jag is a 1998 xj8 sport with 3.2 v8

It is perhaps possible that the on board diagnostic program may not have completed. In other words may be just a simple glitch on this occasion. Time will tell. Drive and see if it occurs again.

I`ve seen this on once on my V8 S-type although the throttle body and several other components are dissimilar.

Ahh ok thanks Mike.
Ill keep an eye on it and will let you know

danr,

308s seem more prone than most models to the dreaded restricted performance message.

It may be nothing or could be a symptom of a failing electrical circuit. I had it some years ago and it ended up being a failing temp sensor.

It would be helpful if you can get a fault code for the symptom. Diagnostic packages and OBDII plugs can be sourced for £10 if you want to check it yourself.

Good luck

Paul

how old is the battery ?

as all the lights and wipers that have been needed lately will have taken its toll on a failing battery not to mention the dip in temp outside.......

if over ten years old, it will probably be your problem

at least its some where to start looking ,
