| Intermittent D4 Reduced Power Mode |
|
Morning, New to the forum and to the world of Discovery and LR! (the wife had an Evoque before, but not counting that!)
I purchased a D4 on Friday... Its a beast... HSE spec, Black, Mrs is happy...life is good.
I have a quick question. The car keeps showing an intermittent Restricted Performance fault... usually comes on after a few miles when the engine is warm. There was a hole in the rear o/s light allowing water in, but I have fixed this and dried the unit out with the help of my neighbour.
Has anyone experienced anything like this before? would be interested t hear the cause/solution.
We have run diagnostics but each time the fault is different. 🤷🏻♂️
Car booked in for dealer diagnostics at 1630, but as I'm sitting here thinking about it I thought I would see if I could get any clues from you guys.
Sorry if this is in the wrong section... never been in a forum before!
Kind Regards
Ryan

Hi I had this issue as well. In my case it was caused by the water in fuel sensor on the fuel filter.
I initial had the fuel filter changed, then had the water sensor changed(This screws into the bottom of the filter cartridge). Neither of these cured the issue.
I then had the filter housing changed (The part the filter cartridge screws into). This cured my Restricted Performance issue.
Hope this helps
