2016 XF S 3.0L engine

 

car just stopped - no warning lights 

FSH - 4 with JLR , 2 with approved JLR garage 

 

Jaguar in newbury just quoted £20950 to replace the engine and there is nothing they can do to help 

 

I have seen people managed to get them to pay a % or in some cases 100%

They won’t however , tell me what’s has happened or how -is this normal ??

 

what is the best way to escalate this matter as they are not being helpful at all
