Should you REMAP or EGR/DPF DELETE your TDV8 Range Rover?

Sam. Hi had my 4.4 remapped to stage 1, 405Bhp, 780NM, and the EGR blanked & mapped out, leaving the DPF in situ. To start with, the engine runs much better and quieter. The MAP sensor no longer gets dirty at all. Oil viscosity is hugely improved, and to date there is no measured oil contamination. I’ve covered 6K in 9 months, and I’ll be honest most journeys are short. But I can get the DPF to regenerate over a 13 mile trip between two local Mway junctions. I regularly check the DPF with my iiD. I drop the oil every 3K, and now use 5w40 oil. This is purely for maintenance, as I believe a clean engine is an efficient engine. I’m due to drop my oil again in another 200 miles, and am planning on videoing the filter & oil change just to highlight the condition of the oil…. I am also planning on having it tested. Now to MOT testing. My friend runs an MOT testing station, and basically says diesels always pass the emission testing, because emission parameters are set for the model year. So my 62 plated L322 will only ever have to achieve the 2012 Emission Regs. I had it MOT’d at a JLR main dealer, with the EGR blanked & mapped out, and it flew through with better figures from the year before. Of course, if they had the right to plug in an OBD reader, then I would be stuffed, but it is only a 5min job on the 4.4 to remove the blanking plate! Good video… keep them coming!

Technical and practical , great vid. Good luck with workshop

Excellant and looking forward to the garage update and more videos.

Great video. I'd be more than happy to watch more of these types of films, thanks.

Music to my ears! Glad you are enjoying the results, safe driving! PS: It's essential to point out that most modern diesel turbo, injector or engine failures occur purely due to clogged emission systems.

Great video and topic to explore! Having a general outlook of "if it ain't broke, don't fix it" and only modifying car components once the OEM needs replacement has served me well so far. That said, if I could snap my fingers and be without two-stage EGR, EGR cooler and SCR exhaust on my VAG Euro 6 diesel, I absolutely would. When the DPF eventually clogs, I'll explore the 'free flowing' options at the time I think 😉

I’ve had an ECO map done on my 4.4…. It just makes it a little more smoother and power seems to be relentless!

So glad I bought a td6 🤣🤣 no probs with so called chocolate gearbox just full service every year and no dpf to worry about 🙌🥳🥳 I just changed my egr to brand new one for the first time in its life and engine is still as healthy as a butchers dog lol I don’t know how anyone copes with these new dpf filters sounds like a nightmare to make sure there working properly all the time anyway glad to see you back sam I’ve missed ya vids 👍

Good video Sam 👍👍

Hi Sam hope you and your better half are well .how easy is it to change ace block pipes with out taking the body thanks for any advise

I’ve got a twin map on my Td5 one for towing one ultra lean for the mot . I’ve got my 4.4tdv8 performance mapped I’m waiting for the guy to develop the twin map for it . Mine is deleted but done in such away that it all looks standard. They nice to drive standard there a lot of fun mapped

Another good video Sam 👍👍👍👍👏👏👏👏

Really good, balanced information. Any thoughts on modifying the L322 3.6 TDV8?

Good video. I have EGR mapped off but have kept the DPF as have never had any DPF issues. Is that okay? Or does one need thr other to function. Ive never got a conclusive answer but have done 25k miles with no problems

Just to recap , just completed my journey back from Spain to the UK, journey about time about 27 hours, In my 2016 L405 Vogue ,this is with the EGR warning light, lit up to keep me company all the way, I was a bit anxious , kept checking fuel consumption, any additional exhaust smoke, temperature guage, but all seemed fine plenty of acceleration full range no hesitation, all seems fine apart from this dammed light, will find out tomorrow, as it goes in the garage at Range Rover in Gateshead , Replacement L-EGR for sure, DPF ? I hope not ?.

Have a bmw m57 remapped for the last 60k on 169k now,change oil more often and youll be fine

Cheers good insight..... now I need to get up off my arse get more money earned and get myself a lovely Range Rover.

Hi Sam…So is an Eco Re-Map ( which is legal…with insurance notification?) actually worthwhile without doing the EGR and/or DPF delete(s) ..which are not legal to drive in UK and may be spotted as testing rules get tougher in the future? Basically ..would you recognise a performance difference with just the re-map? Any thoughts?

Just got a quote from Celtic for eco remap and EGR software delete. Did you (theoreticaly) physicaly blank the EGR as they state this must be done beforehand but don't know if this is generic advice or specific for this engine.

Sam have you tried DPB 100 in you vehicle

If im not mistaken the 4.4 TDV8 was produced in Mexico and the 3.6 TDV8 in Dagenham.

My L322 4.4 Westminster 2012 has nearly 200,000 miles on the clock. Would it be safe to re-map it?

Could probably get away with it for a bit but the UK GOV is proposing to introduce more stringent emission testing to catch out DPF and EGR deletes and have done a consultation excercise on this Having said that my EGR cooler is leaking which is a big job to replace and one solution woud be an EGR delete so I could bypass it in the coolant circuit. People have said the DPF won't fill as quick without EGR which would be another benefit for all owners who now have DPF's with significant ash content.

I think a lot of it comes down to whether you do a lot of your miles in an urban area or not. In the countryside I'm all for emission controls to be removed. Hypothetically of course. But I live in London so I have petrols. Diesels just don't make sense on short journeys. If you bypass the DPF in an urban area you are screwing people over. Same for EGR and cats.

Iv my 3.6 egrs blanked and remapp

The 4.4V8 was built in Mexico as Ford wanted it for their F150.

If you reduce fuel consumption, then, you are also reducing CO2 (global warming) emissions. EGR and DPF are good for local emissions in built up areas, but bad for the planet because they impact efficiency and therefore increase CO2 emissions.

Great video mate

Good video overview 😊

Great to see you again still like to see work on the p38 , I own a evoque and have had the egr deleted ( software ) and also the Adblue deleted , I am getting MPG which makes you think all these parts helping are also causing you to use more fuel
