Not posted in here for a while. The last 6 months have been a nightmare with the DPF. I'm now on my third replacement, the first two (long story) it transpired were not regenerating as they were not genuine JLR. The previous were giving red alarm after only two days returned from the garage. It's now been 9 days and no issues so far. The garage has done a lot of free work trying to get it right and it looks like going for the cheap pattern was the wrong decision, they never asked by the way, just said a new one is £1100. I paid £480 last week for the difference. Car feels better than it has done since I bought it June last year. I'm hopeful it's now fixed. Trips up and down the motorway at 65 approx every 250-300 miles will be part of the owning regime going forward. Hint you can tell by the mpg display of your car is doing a regen, don't ignore it, keep it driving at as constant speed as you can on cruise until you see the mpg creeping back up, use one of the other trips to confirm. You should get into the 60's on a steady dual carriageway run.
Whatever you do don't be tempted by removal
