    One for the wise and experienced...

    Well, that made you click in, didn't it!
    But seriously, a couple of questions re EGR and fuel filters.

    1) EGR - my 2016 D4 SDV6 is stock standard in the engine room, but I'm wondering as to the benefits and downsides of blanking off the EGR, and the difficulty or otherwise of getting it done. We live in Dunsborough, regional WA and most of my travel is long trips, 200km to 300km at a time. Is this good, bad or not applicable for the EGR valve?

    2) Fuel filters - we do a bit of off road once or twice a year, towing a heavy camper trailer. Planning another trip to the Kimberley next year. Given the possibility of dodgy diesel at some of these remote places, is it worth it - or necessary - to have a secondary fuel filter installed?

    We took it along the GRR and off shoots last year and no known problems on that trip.

    My understanding of how the EGR works with your model is that for long driving trips, as you do, it probably has little effect. The problem I understand is worse when lots of short trips are undertaken.
    With fuel I reckon you stand more of a chance of dodgy quality at some of the discount joints

    Greg, I would talk to Kevin at Rovertech for a bit of advice as he has recommended it many times. I got my remap and EGR blanking done by Autocode ECU Re-Mapping | Performance Tuning | Electrical Fault Diagnostics when I first got my car. Since I'm going to keep it till it dies (or me first) I thought let's make it breath easy for it's lifespan so I went ahead. My understanding is it's done by software, so I can be removed easily.

    Thanks Rod, I'll talk to Kevin. With the EGR blanking, is it necessary to have the engine remapped as part of that process? I don't particularly want a remap, certainly not while the car is still under warranty. I had my RRS remapped soon after I bought it back in 2010, and was always nervous about warranty claims after that.
    But a local mechanic has told me that EGR blanking is not just a mechanical thing, there needs to be some software adjustment done at the same time.

    Thanks Simmo. I've never had fuel problems on many previous trips to the Kimberley. Mind you, carrying a long range tank, I generally only need to fuel up once at Mt Barnett, between Derby and Kununurra.

    remap is not required to blank.

    Greg,

    Kevin did mine while replacing the turbos. In my case they were permanently removed, which makes it possible to get at the turbos without body off.

    He gets Mark down the road to install an emulator. Mine was one of the first SDV6's that he managed to get the emulator to work on. People on here have great difficulty contacting Mark but Kevin has good access to him, as long as he sees him in person rather than ringing. The two companies are only about two or three hundred metres apart, which is convenient and they help each other out.

    Hi Bob, yeah I spoke to Kevin this morning and he recommended Mark - and said it was almost impossible to get him on the phone. I'm not in a hurry, but I'll get it done in the next couple of months. From what Kevin told me, Mark tweaks the ECU so that it thinks there's no EGR, and permanently shuts the EGR valve.

    YEs, apparently that's the process, plus shutting the valve permanently.
