Jaguar XF 2009 - Restricted Performance warning persisting - Joanna319

I’m looking for a bit of help and advice with my diesel car I recently purchased.

The low fuel warning came on with 50 miles left and then the Restricted Performance notice so I drove home and to the garage by which time it had 35 miles of fuel.

i expected the RP to go away after filling up thinking it was fuel related, but it has persisted unless I am heavy on the accelerator, when it does go away. However, cruising even at speed makes it come on again.

What would make it appear and stay unless I floor it?

It has just had a full service last week with oil and filter replaced and everything else checked out for a clean bill of health.

I wouldn’t have thought the fuel level was low enough to cause any problems as I often drove my old car with much lower levels with no issues.

Any insight and advice welcome as I am still trying to get to grips with learning all the foibles Jaguar seems to have, including the battery going flat if it’s not taken for a long run every week which I can’t always do.

If I can get rid of the RP warning, it’s going up for sale.

Unfortunately these are old cars now and diesel running problems are common. You’ll need to get some diagnostics done to find out what is going wrong.

If recently purchased from a trader/dealer take it back to them. You've probably bought someone else's problem.
