XJ DPF regeneration.

[Trevor Hill]

I have a 2006 XJ TDVI, lately the DPF seems to go into recycle mode more often. I have changed my fuel suplier as I no onger have a fuel card from work. Would this be the reason or is it something more serious? At no time have I ever had a warning light on the instrument panel.

I`ll take her for a spirited drive on one of my many private tracks. Is this definitely not fuel related then?

How do you know that is in a regen phase ? Does a warning light or something come up, do you notice a change in performance ?

You will notice a lot of smoke coming from the exhaust. It has only happened 3 times in the last 3/4 months, but I never noticed it before and we have the car two and a half years. It seems to have happened when I changed fuel stations, but the car is no longer on the motorway everyday and is doing much shorter journeys.
Thankfully I had a Touareg which used to regenerate regularly, so I knew what it was and didnt panic, but other motorists think the car is on fire.

I contacted the dealer today as I had a lot of smoke coming from the car after a 50 mile motorway journey. The dealer says it is definitely the DPF regenerating and that they sometimes get a bit smokey. It cleared after a few minutes and went back to normal but it does seem to be happening all to regularly. Should I take the car to the dealer to get it scanned or am I worrying unnecessarily.

Thanks.
