Hi everyone - new here although by no means new to the "joys" of owning a Jaguar... As I was driving last week the red "DPF Full - Visit Dealer" message appeared and the vehicle entered restricted mode. I drove it home on the motorway using paddle shift to overide the automatic gearbox but it didn't seem to make any difference. I called a local independent JLR specialist and they said that in most cases, this problem can be fixed by cleaning the DPF and then doing some sort of computer magic to clear the error as long as it's looked at straight away (i.e. don't drive it around for weeks and months with the light on). However they did say that as far as they were aware, once the red DPF full message came on, you couldn't get rid of it by forcing the car to regenerate the DPF and that if you took it to a JLR main dealer, they would probably tell you that it needed replacing. So I booked it in for a check and dropped it off this morning, stopping on the way to put a bit of fuel in as it was getting a little close to the 50 mile range. I put just over a quarter of a tank of Shell V Power Diesel (anyone outside the UK, that's a premium fuel) and when I started the engine the DPF Full warning had gone, performance restrictions had gone although the EMS light remained active. I left it with the garage as planned, explained what had happened and they were a bit surprised the error had cleared - but I guess we all learn new things every day. They're going ahead with diagnostics and I will let you all know the results and any work that they do to fix/correct the issue.
As well as that, their advice for good maintenance of the DPF system however is similar to what's been said here:
Don't use supermarket diesel
Use Premium fuel if you can
Use things like Millers Additive in your fuel
Give the engine regular motorway journies
Sorry if that's teaching anyone to suck eggs but that's a complete run down of what has happened so far
