Okay guys, here is how this turned out. I had to escalate the warrantee issue all the way to Land Rover of America Corporate office. After a week, they denied the warranty stating that it is not a warrantable part. AGAIN, it is clearly a part. This morning I had it towed to European Service Center on Roswell Rd. I had it towed because LAND ROVER OF BUCKHEAD told me it was not running and had to be repaired before it could be operational. After it was towed, I asked to tow company ($225) if he had any issues getting it on the truck and he said no, he just started it and drove it onto the truck. I had to laugh. These guys are crooks. I can't say that the LRB were rude or didn't act like they were trying to help, but I can tell you Ryan, at their corporate office was VERY rude and refused to let me talk to his supervisor after denying the warranty. I am going to take this to the EPA because they are the ones that mandated the 8year 80,000 mile warranty and I fall under 8 years and 80,000 miles. Honestly, I have to worst taste in my mouth ever and this is the last Land Rover I will ever purchase or own.

How do you clean the DPF on your own? I have watched the UK videos and my mechanic is willing to try but does not have the right tools. I replaced the throttle body and just recenlty the upper intercooler hose which the rubber portion ripped due to oil in the hose. We think there by be an oil link in the turbo.
I wouldn’t trust that it’s an accurate diagnosis. If they’ll cover it under warranty then maybe there’d be no harm in having them do it, but depending on what triggered this diagnosis, there’s a good chance it’s a much cheaper and simpler fix.
Watch O’reilly’s mobile mechanic on YouTube and he deals with these on a weekly basis. He’s based in Europe and the fault codes and countdown are an extremely common problem on nearly all diesels with DEF/DPF systems. Typical causes have nothing to do with the actual DPF filter and yet are frequently misdiagnosed by LR shops and specialists to the tune of thousands of dollars of repairs that don’t solve the problem. There’s a small chance the DPF filter itself is the issue, but I’ve seen a number of people that had the entire system replaced just to have the exact issue come back the next day.
Dirty DEF injector may need cleaned if it hasn’t been done, throttle body may be sticking, MAP sensor may be covered in soot. I let my DEF get low on a towing trip this last summer and it triggered a fault that I’ve been battling off an on for the last few months, but measurements on the DPF show low pressure and very low soot mass.
I’m only a thousand miles removed from my most recent DEF fault, so I’m still unsure that I’ve solved the issue. I fully expect it to come back at some point, but I’ve cleaned the DEF injector, replaced MAP sensor (I damaged the original when cleaning it), I topped the DEF off and used the GAP IID tool to reset dosing adaptations and restart catalyst start inhibit as well as using it to trigger regens. That was only about a thousand miles ago, but I did a towing trip in that time as well as a handful of around town trips and so far the warning hadn’t come back. I know I just threw a lot at you and if you’ve already researched and attempted these things, I’m sorry. I just would almost be willing to bet money that the DPF filter is just fine - it may need a cleaning, but that also can be done cheaply and easily on your own.
