Lately my mother has been complaining about the car being a bit sluggish and quite thirsty. MPG is right down to 32! That's with 60/40 town/motorway driving Used to be around 40 ish.
I went for a drive earlier and it does feel sluggish, however, it doesn't smoke one bit. As I was turning into the car park the EML (limp mode, 2700rpm max) came on so I popped the diagnostic thing on and it said: Barometric pressure not plausible with boost pressure. I pushed on the boost sensor connector and the light went off, no more limp mode.
Went for another drive and still sluggish...checked on the diagnostics and all was ok. Turned the engine off and set about fiddling with the computer
On the center display the outside temperature read +10.5°C, BUT on the diagnostics it said that the outside temperature was -16.1°C!!!!
It's an auto, but the gearbox is fine. I changed the fuel filter 3 weeks ago. Oil and air filter are due next month.
I have to add that it's been a while since this engine sounded right. It's louder than most 2.2DTi's...and much louder than a neighbour's that has over 300k on it
