Model: 2.0 dci aventura explorer T31
Year/Plate: 2008
Hooked up my little obdii reader (xtrons) to see theres an error code p2a00. I see this is to do with an o2 sensor. Cleared code and restarted car, checked again and it returned. Funny thing is though there is no engine management light on, the car has full power and it isnt running rough. Great acceleration. Only thing maybe wrong is the mpg figure on the dash is always reading about 34-36mpg even cruising on motorway.

Would I also be wrong in thinking this car doesnt have a dpf fitted (2008 T31, 2.0 dci aventura explorer) I say that cause when looking at ats euromasters for a service cost putting in regi it says "[model info] - without dpf"

Any thoughts ?

I have exactly the same model, same year, although yours may be manual whereas mine is automatic. Mine definitely has a DPF as I have had the light come on a few times and have had to regenerate it.

Strange what you say about MPG figure on the dash as mine seems to permanently say 31mpg. I have just come back from a holiday towing a caravan, and the MPG figure stayed the same throughout the holiday, whether I was actually towing or not. It has read the same ever since I bought the car two years ago. I even cleared it once and it still came back to showing 31MPG. I keep meaning to do a proper MPG test to see what it is really doing, as that figure suggests that it uses much more fuel than my previous cars and I don't think it does. Difficult to tell though as my mileage has changed considerably since the covid pandemic.
