S Type 2.7D Particulate Filter
Discussion
Hi
Had a problem with the car going into Limp Home Mode. Local garage diagnosed it as a Particulate Filter problem, and has done a manual re-generation of the filter, and things have been great since, and it didn't cost me my right arm.
Following this, googling, I see that there are a few companies out there that offer to remove the filter, re-map the ECU to over come alarm codes etc, to remove any future issues, anyone had this done? Just planning what to do should the same fault come back in a few months.
Also, can anyone offer a simple explanation of how the regeneration works? Does it use battery power, or is it with just the heat from the engine? The reason I ask is that I have an ongoing problem with the electric hand brake failing to operate (I have already replaced the battery as this is documented as the main cause of this fault), and it always seem to happen after a long run when potentially the filter should have been regenerating, and since the garage sorted out the filter, the hand brake has behaved itself, so I was wondering if the filter was battery powered, if it was pulling the voltage down causing the hand brake fault after a long run?
Clutching at straws, probably wrong, it will probably throw another fault again tomorrow!

The electric handbrake (the Devil's work!) has nothing whatsoever to do with the DPF and its regeneration.
The extra heat required for the forced regeneration is provided by the engine over-fueling to bring exhaust temperatures up.
An amount of the "over-fueling" diesel manages to get past the piston rings, and will dilute the engine oil.
So please make sure that the garage did an oil change when they did this forced regeneration. If they didn't, first thing to do is check the engine oil level. If it's higher than it should be, it's been diluted with fuel, so make sure you get it changed ASAP.

I had this done on our diesel focus a company in essex fantastic reslts and been thru couple mots since. they cut open along the weld remove insides and reweld then modify the cars brain, today our xf came up with full dpf and are looking to have the same done to this, however will be using a company close to portsmouth, you will get people giving negative views on this for all sort of reasons. the filters are a pain for short trips and with them gone much better economy and performance, get it done and also a remap greatly improves the jaguar diesels. ours is a 2-11 3.o d remap with over 300bhp and sooooo much extra torque. No regrets

Have had it done with various cars. No issues. In fact performance and economy gains.Had a problem with the car going into Limp Home Mode.

So, 1,500 miles later the DPF problem returns.
Very nervous at having the filter removed due to all the stuff on the net about it been illegal, so I want to go down the route of getting it fixed.
My local garage says that all the evidence points to a faulty sensor and not a faulty filter, which I am told is as common a fault as the filter its self.
Anyone had the same issue resolved by changing the sensor?
Mine gets fitted on Thursday
week before the mot our 3.0 xf showed full filter no other warnings just full on in red !! had our remap chap take it away and had the dpf cut open gutted and rewelded, remap to eliminate dpf sensors etc in for mot and passed.
you will keep paying out if you do short trips with dpf in place... have the thing gutted, done with .
