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!

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
