Hi Peter Regret No supplying dealer is not a Jaguar franchise though operates several garages with associates across UK. They took car back to Leicester and sorted problem identified by a Jaguar independent in Southampton, they refused to pay local repair costs hence return to their main garage (though I responded to an advert in Hampshire) as I said they told me the turbo actuator had been refurbished. The XF has no dipstick oil is checked by instrument panel so i can't dip it to smell if contaminated, low ash oil was used at service when DPF replaced, so almost new.

Hi Peter Many thanks for your response, the car did not smoke before the DPF/EML lights came on with restricted performance as well, the garage replaced the 82grm (full) DPF and said they had reset the sensors etc., there was no 'gasket' fitted to the new part and joint leaked, for this reason the car was returned to them. They ordered and fitted a new 'joint' retested and found a faulty sensor, the work was completed and car returned to me. The smoke is quite bad on hard acceleration, and because it didn't smoke before, I don't see how it can be 'sooted up' beyond the DPF, the DPF itself is supposed to eliminate soot, if working correctly how does a sooty emission get past it? Research says the ECU needs to be told a new DPF is fitted and reset, am wondering if this was not done right, engine still thinks there is a problem and sets to regeneration mode to clear it, that would explain excessive fuel consumption and perhaps due to over fuelling the sooty exhaust. Am thinking now to have it checked out by a Jaguar specialist garage using much better diagnostic equipment, and taking it from there. The supplying dealer previously had the car back under warranty and said they refurbished the turbo actuator, am wondering if this part is also the cause if 'repair' was not 100% successful.

Bought my 2009 reg, XFS a year ago. often needed to do the 'regeneration run' that usually worked for a while, eventually DPF light and EML came on with restricted performance that would not clear. Local independant garage did a diagnosis reporting DPF contained 82gr soot and required replacement, they fitted a pattern part and reurned car. There was visible smoke and soot coming from DPF/exhaust joint, car returned and new 'gasket' fitted along with a sensor, all lights now out, car quieter but visible smoke from exhaust on acceleration or blipping throttle at standstill. A long fast run decreased the smoke but its still present. Anybody had similar or care to comment, (mileage a bit over 83000) it also has high fuel consumption. Luqa
