'17 TD6 needs a new DPF. I have 78k miles on it. NYS inspection is up and it needs to pass emissions here. All the warranty info suggests I should still be covered under the emissions 8/80k warranty.

Anyone here had experience with this? How much of a battle am I in for? My plan is to show up at the dealer, tell them I want it to pass inspection, put down the printed out warranty info, and tell them I am not picking it up until it has a new DPF.

Thoughts? Appreciate it.

Related side note, I have called the Rochester New York JLR dealer every day for the past 6 days and left three messages, the last time I got someone from sales who apologizes all over and said they were completely overwhelmed and had no one to work. Said she would definitely give service my note, and havent heard anything. I then Called Buffalo and Albany and no one picked up there either. Yet there is a 100 car per dealer wait on the new RR, and its the most re-purchased car in the country. This brand is insanity.

 

Just spoke to the Buffalo dealership, they told me while they have seen this before, its a whole process, and what I should do is call JLR NA and start with them. We'll see.

 

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.

 

I am being told that my '17 Discovery HSE diesel is SCRPF is not covered because the SCRPF can be ordered separately from the Catalyst. The warrantee states that the it's covered where the SCRPF is integral to the SCR. Integral by definition means essential or complete. The catalyst cannot function without the SCRPF, therefore is integral.

My local dealer didn't bat an eye. 79,600 miles. Didn't have to argue at all. I just brought it in with a CEL without claiming anything. Picked it up a couple days later and it's been great ever since.

 

Yeah, different models have different assemblies. Their "argument" at Land Rover of Buckhead is that the DPF is not the same component as the Catalyst, therefore is like any other filter (this is not a $200 filter - their price is $4,342.67). It is clearly a PART.

 

Interesting. Mine was replaced at North Atlanta. It's the same franchise as Buckhead as far as I'm aware. I also thought the DPF had a small pre-catalyst right above the DPF, lending to it's odd bent shape and making it "integral."

Also, if it's not an item that they could legally remove and reprogram the ECU to accommodate, then it's federally mandated and falls under the warranty, IMO.

 

Apparently they have the same policy. I called them after your first response...

 

The diesel oxidation catalyst (DOC) is ahead of the DPF and they are integral. Dealer is probably referring to the catalytic converter aft of the DEF doser. Both can be bought independently or as an entire assembly, I bought the entire assembly as to not have to cut and clamp and I didn't want to mess with the catalytic converter again down the road

 

That's what I thought I remembered from reading the service manual. The pre-catalyst is integral to the DPF and *cannot* be replaced separately from the DPF. As such, It is integrated. The dealer should honor the warranty on the federally mandated emissions device. Escalate it to the EPA and to JLR corporate.
