Hi All,
I know this is a daft question as I'm posting it in to the XKR category so I kinda no the answer before I ask but.......
I'm getting about 14MPG at the moment.
I'm not driving like a lunatic and am generally doing about 5-10 miles a day through the city.
I'm putting 97 grade fuel in.
A few weeks ago I had an engine management light come on so I took it to my "friendly" local Jaguar main dealer and they "advised" that I needed to change both cats and all four O2 sensors at a cost of about £3K.
Ouch I thought, so I bought an OBDII reader and got the following code myself.
P0420: Catalyst System Efficiency Below Threshold (Bank 1)
I spoke to a few independent Jag specialists and was told it was highly unlikely to need the entire exhaust system replaced and that it was probably just a dirty O2 sensor.
I therefore put in some CatClean (that I had read some good reviews about) to a fresh tank of fuel and reset the fault code.
I've since driven for a couple of weeks and probably about 100 miles or so and the fault light hasn't shown up again.
Two questions:
a) is my 14MPG average consistent with XKR ownership?
b) if not then am I likely to be burning excess fuel and have just blagged the car in to thinking all is well when something is most definitely not?
She's a 2007 model with 115K miles on the clock.
Any help and advice would be very much appreciated.
Cheers,
Mat.
