Thanks. What is the recommendation? DPF and DEF injector cleaning?
I drive a little and add diesel, exhaust filter alarm gone. But the CEL is there.

 

If you're smoking, the DPF is broken and can only be repaired by replacing it. I imagine that the DEF injection system initially failed causing the DPF to crack and then foul the EGR. I'm not sure how long ago you purchased the truck, but if it was around the time of your original post there's no way the selling dealer didn't see the check engine light and cleared the codes before selling to you. If there are any buyer protections or return period where you live I would recommend you use them. The DPF alone is a pretty expensive repair. EGR is probably second and the DEF injection just behind. I wouldn't repair any of it without doing it all or you run the risk of damaging a new DPF.

 

Thanks. Yes have been with the D5 for just 2 weeks. Last week at the dealer. They “change” just the ox sensor.
it’s smoke then stops after many miles. But the smell is also strong.

 

This morning. No smoke but strong smell. RPM steady. She feels super ok. Still CEL.

 

I'm not a diesel expert by any means, but I spent a lot of time researching modern diesel function and going over the service manual for my TD6 D5 when I had issues with the DPF that led to it needing to be replaced by the dealer.

Let's talk about a few of the codes that you have...

P2002-00 - Particulate filter below efficiencyP0420-00 - Catalyst low efficiencyP0498-00 - EGR insufficient flowP22FE-64 - NOx sensor implausible.P226D-00 - Particulate filter deteriorated or missing.P246B-00 - Conditions incorrect for vehicle regeneration.If I had these symptoms on my D5 I would be very concerned. I expect the repair bill at my dealer would be in the ballpark of $8-10k USD. The DPF/SCR replacement itself being around $5k of that. This is not something that broke after you bought the truck. It has been slowly deteriorating over years. Excessive regenerations due to a malfunctioning DPF can cause excessive oil dilution with diesel fuel leading to a breakdown of engine bearing surfaces. I don't know what legal protections you have in PR, but it is against the law in many US states to knowingly sell a vehicle that cannot pass federal emissions standards.

 

Thanks for the detailed explanation.
I will bring the D5 again to the dealership.

Also,
I noticed DEF not going down. What is the ratio of use?

 

I'm on my first fill of DEF after having our DPF replaced. After 2500 miles it says fill 1.6 gallons with 2900 miles to go. DEF is primarily consumed during regeneration since a significant amount of NOx is generated due to the high temperatures required to burn soot out of the DPF.

 

Thanks.
For me after 200-300 miles still at 4660. Like no def was used. On m way to the dealership (non JLR)

Picture of the exhaust:


Looks new. Super clean?

 

It's possible something might have been replaced at some point in the past. The DPF and SCR are a single section of exhaust from the factory. They can be replaced individually, but that requires a cut and clamp just upstream of the DEF injector. I see a clamp there. While the SCR section (right side of your image) looks bright and shiny the DPF (seen through the bottom shield) looks original to me. Nothing cosmetic will indicate the function of the components, however.

 

I've consistently been getting just over 4,000 miles between DEF fill-ups. You may need to go more than a few hundred miles for it to register.
