Welcome to the Jaguar XF Forum.
just bought an xf
i have just bought a 2008 premium luxury 2.7 td loving it so far .just a couple of things i need to know .
the air vents donít always open electrically and twice i started the car put in gear and it says geabox fault
.switch off start again and itís all fine .ttheres no problem with the box it changes smoothly and when it should all the time . i have read online this could be a battery issue. the car has been at the sales place just sitting for a while . battery voltage without starting the car and all switched off for a few hours is 13.4 running its about 14.8 the cold voltage seems a little low to me .could this be the issue . sometimes get a red battery triangle on the dials just before startup .
