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

[@JohnBaxendale]

Honestly, not sure whether mine's been done already, have never noticed it doing a DPF regen in the 4 years I've had it...

[@SamsMotors]

That is pretty unusual! They are usually fairly obvious when they are regenning.

[@JohnBaxendale]

@@SamsMotors Yeah, that's what I figured, will have to investigate a bit more though I'm not entirely sure how to check without pulling the exhaust off and inspecting :\

[@simongould9688]

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!

[@SamsMotors]

Only thing to be careful of is the ACEA grade of your 5w40 oil. If it is high SAPS (e.g. A3/B4) it will cause the DPF to clog more quickly. Castrol does a 5w40 DPF compatible oil now though. Thanks!🙏

[@simongould9688]

I know Sam, and that is what I use. Expensive…. But a damn sight cheaper than new turbo’s!

[@johngriffin641]

@@simongould9688 did the interval between regents increase appreciably?

[@simongould9688]

@@johngriffin641 Hi John. Just picked this up, because I’m on holiday. I would say hand on heart, yes, the interval increased enormously. I was very nervous about having the DPF removed/altered(cored out)/deleted . I had already blanked the EGR on my TD4 Freelander, and also both EGR’s on my 3.6 TDV8, so knew what to expect. But, the engine is so much smoother, and cleaner. Fortunately my 4.4 had only done 60K when it was done, so there wasn’t a massive build up in the inlet doughnut either.

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

[@crunchynutcornflakes]

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 😉

Have a chat with Mr Ben’s Garage about that one! But generally speaking, yes, they take to a remap very well 👌🏻

[@johngriffin641]

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.

[@JohnBaxendale]

Not sure that's correct, you would still have to fix the cooler leak regardless of whether the EGR is blanked/mapped out AFAIK.

[@johngriffin641]

With no EGR flow there is no need for coolant flow through the EGR cooler so bypassing it by joining the coolant in and out pipes would remove the leak.

[@JohnBaxendale]

@@johngriffin641 Presumably still potential for oil leaking out via it though?

[@johngriffin641]

@@JohnBaxendale There is no oil feed to the EGR cooler

[@JohnBaxendale]

@@johngriffin641 The typical oil cooler failure on the 4.4 TDV8 causes coolant to get contaminated with oil... so there's presumably somewhere where the two can mix when a failure happens.

Hello from New Zealand. Thanks largely to your videos Sam I've bought a black 2012 Westminster, only 75K miles with full service history... I was under the impression you can't delete the EGR and DPF on the 4.4? Really keen to do a remap, but it's all connected. Also, have you had the second turbo oil drain modification done on yours? Worth doing a video on it?

[@SamsMotors]

Thanks for the message. I wish I had had a TDV8 Range Rover on my last visit to NZ! It would have been a lot more enjoyable than the rental Camry that I travelled up and down the country in! EGR and DPF deletes are definitely possible and usually done in conjunction with a remap as the control systems can be appropriately modified at the same time. I don’t believe my car has had the modification, as it occasionally does the turbo smoke puff. 💨 I haven’t got any intentions of doing it currently as it seems to have had no ill effects thus far 🤷‍♂️

[@carbostar]

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 ?.

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

[@SamsMotors]

The EGR can help to reduce soot output a bit at idle, but it shouldn’t have a huge effect overall, especially if you are doing enough long trips to let it regen regularly.

[@ianmitchell8162]

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?

[@SamsMotors]

Definitely... the other modifications are totally optional. I would be wary of going much more aggressive than the Celtic Eco remap that is on mine though, as if the engine generates a lot more soot than standard, the DPF won't thank you for it!

[@georgecook4983]

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

[@johngriffin641]

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.

[@SamsMotors]

That would likely be generic advice, as there's no need for any physical changes to the 4.4's EGR

[@johngriffin641]

@@SamsMotors Had this from Celtic when I asked about just the EGR delete"We only offer our EGR removal software if 1) you visit us in branch (Derby or Newquay), 2) the EGR has a blanking plate fitted prior to the appointment, and 3) you sign our disclaimer accepting that it is for offroad use only, as there are laws governing emissions control devices use on public roads" Don't know why they need it blanked as I assume the software just stops it functioning. The only reason I could guess it needs physical blanking is if all the software does is just ignores any error for loss of EGR flow and doesn't throw a reduced performance routine.....

[@jordanbridges8962]

From my recent experiance, you can't blank the 4.4 TDV8 EGR in advance of the appointment. Mine is booked in for DPF and EGR delete on Wednesday and I did the physical work this weekend. With the EGR blanked, the engine ran like crap at part throttle - stank of fuel and smoked. As the management is clearly expecting the extra flow but not getting it. Removed the blank and it's back to normal, so will refit after the ECU change is made. It's very easy to get to on the 4.4, and only 5 bolts.

[@richardschofield2201]

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.

[@SamsMotors]

Absolutely, there's not really a one size fits all with this.

[@user-xu5vl5th9n]

No car makes sense for short journeys most of the time, at least the oil change interval needs to be much shorter. DPFs are just worse again. If people could see the oil temperature and understood how this can make an oxidised, glutinous sludge in the engine, they may think differently.

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.
