Hi Rik.

I think when you have a red light, you have to get a forced regeneration at a garage.

Doesn't your handbook explain what to do, what i'm led to believe is if you have a yellow light you can go for a 20/30 minute drive after the engine is up to normal temperature (ie a Hot engine ) to get a complete regeneration. When a Regeneration is starting with my car I find that the the engine revs are idling higher than normal ( up by about 150 revs ) or the exhaust is making a louder noise than usual ( as if there's a hole in the exhaust )  if this is happening don't switch off the engine and go for a drive. Diesels are meant to be Driven as some members say give it a Italian tune or sometimes drive it as if you had stolen it.

In nearly 6 years i've never had a warning light come on, i've certainly had a few Regenerations and they can occur when your not suspecting it ( I was recently driving to the Cairnryan ferry and after travelling some 120 miles I pulled into a service station and yep a Regeneration was taking place so just carried on driving and the engine idling revs were back to normal after about another 10 miles ).

If a Regeneration is interrupted ( ie the engine being switched off diesel can enter the sump pushing up the oil level witch can cause problems ) which is why most member's put less oil into the engine than is mentioned in the Handbook.

I only use 5:5 litres instead off 6 litres and use a Low Ash C1 Oil WSS M2C 934B this is the oil jaguar are now using and we advise to use only genuine jaguar oil and fuel filters. There's also a debate about what diesel too use some members say to use Shell V Power Diesel Or another premium diesel.

I hope this has helped in some way, when buying a car it is usually recommended by members to get all fluids and filters changed and then you know how things are within the engine .

Regards Tom.

Hi Rik,

Tom has given you a perfect answer.

While I have never had the amber light come on in respect of the DPF I have had it come on with the EGR sticking, and to clean out the fuel system I give the fuel tank a shot of Millers Oils Diesel Power ECO MAX every other fill up  -- about ever 6 weeks  - which seems to help, as I don't do long runs that frequently.

Regards,

Peter.

Hi Rick, my xf 3.0ltr 2009 went into the dreaded red two weeks ago and I assume yours has gone into limp mode.I cleared mine by a hour and a half drive on the motorway, when I got home the car was still showing DPF full and still in limp mode but shut the car down completely ( double lock on the fob ) leave it for a couple of minutes and restart and it cleared.I do not do a great deal of miles so I steer clear of cheaper fuel and use bp  ultimate or similar the extra mileage I get out weighs the price. Good luck Alan

Hello,

just a quick one so my dpf light just came up the main problem I have with it that Iv just spent over £500 for replacing battery and alternator, and the lads from garage after dropping my car off said something about clearing the dpf light and taking car for a longer ride.

so I guess the light must of shown on them. Now they advising that it is very expensive to change the filter.

Welcome to the club, Kamil.

The diesel engine in your car does need a long run about once a month --  about 20 minutes keeping over 45 mpg, or putting the car into third gear to keep the Revs higher.

You should also use premium fuel and you can also give the engine an additive [I use Millers Eco plus Diesel] every time you fill up.  I have never had a problem with my S type with the V6 2.7 diesel.

Regards,

Peter.

I had the red DPF full message appear, telling me to visit the dealer. I took Captain Allan’s advice given above in this conversation. My XF had entered limp mode. I took it on a 70 mile drive on the A38, trying to keep the revs as high as possible. The warning light stayed on for the whole journey but, when I switched off the engine on my return and left it for 10 minutes, the car was fine again and had returned to normal performance. Thanks for the tip!!

When I picked up my xf in Coventry and was driving home on the motorway the dpf Amber light came on then red restricted performance.

The next day I added fuel and a good quality dpf cleaner,drove the car to force regeneration and the warning light went out, performance returned and that was a month ago,no issues since.

I add dpf cleaner once a month now.
