restricted performance light

[Paul clover]

i have just bought a 2016 XFR-S 2.0D and it randomly brings up a restricted performance light but when i stop and turn off the car and restart it its gone and may not come back for a few days, when light is off the performance is normal and seems to be no issues, any ideals  what may be causing this ?

Hi Paul, you need to check the error codes. I had this problem and found it to be a split hose. Car ran perfectly until you gave it some gas and then into Restricted mode. Turn off engine and 10/15 minutes later it would be clear. There are  quite a few reasons why this is happening so get a diagnostics check is my advice. Good luck.

Hi,

I have a 2009 3.0 D Jaguar XF [120k miles] and had the same issue pop up recently.

I have now done the following for under £50 total [i.e no labour costs] and all very simple to do.

1 Redex DPF cleaner [£10] one dose in fuel and 30 min drive on motorway & dual carriageway.

This gave a couple of days grace to do the rest.

2.  Air filter [£4.50] + Air Mass Flow meters spray clean [£10.00]

3.  Fuel filter Change [£21.00]

Engine now revs up to 5000 with no issues at all.

I hope this helps.
