Blanked mine around 4K miles ago. Runs not much different to be honest but the service guys have stopped reporting (costly) issues with the EGRs now they are gone.

All I can say is that removing them caused no problems (including MOT). 2005 Range Rover Sport TDV6 HSE in Artic Frost. 20" 2010 HST Alloys, sidesteps, Hawke tips, plus minor bits and bobs along with a remap. Four spike spiders ready for the Alps again now tucked up in their garage boxes...

So far also here everything is fine, am still puzzled actually as to why.

There is a side effect though, I seem to be getting about 2 to 3 mpg more

I have bought the blanking kit from bas, but any will do...

I've been told the light will never come back on and it seems to run a lot smoother......

I think the best place to blank it of is between the EGR and Exhaust manifold, that way you will avoid hot/dirty exhaust gases to get in touch with the unit. BAS doesn’t do it there, they use the pipe from the EGR valve to the intake (and one on the intake), but this is how I will do it at least, it will be a bit more work but will last much longer.

Be aware though, I have read at least of 1 case where the owner of a D4 reported the P0401 error of a 2008MY after blanking it off, so not all engine management systems have disabled this function.

All I can speculate so far is that maybe the original ECU software had the check, and with an update the check has been taken out, or something else has changed. Otherwise I can’t understand why all the documentation points to the egr gas flow check (working on all other EU4 cars I know of). RRS SDV6 HEV Dynamic

Also worth remembering, Pete Bell (BAS) is also working on a patch that will shut the EGR valves perminantly. In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures

That would be great, but then it would also be worth mentioning when Pete will be ready and what it will cost, or?

Am checking regularly, but no codes, not even pending ones.

The P0402 description doesn’t seem to be related as far as I can see to blocking of the ports (it would be the other way around). Could it have been that the code was already there before the job?

Still haven’t gotten time to install the coolingmist unit for cleaning up, but will try to do it rather sooner than later having seen the mess the EGR left behind in your pictures. RRS SDV6 HEV Dynamic

Hi Avos,

I have one question............
Were your EGR Valves Blanked while they still worked Ok. IE they still work but no gas goes through now due to the blanks ?

Even when you blank them off, the EGR valves need to stay operational, otherwise you will get some errors. So if you have a faulty valve now it has to be fixed, as blanking them of will not make a difference (unless of course you have already P0401 errors...). RRS SDV6 HEV Dynamic

If Pete finally finish the software patch then no need to replace the faulty egr, but big question would be if the patch is cheaper than the egr replacement? Pete did mention once that the remap would need to be updated aswell if I remember correctly, I am thinking it must possible to trick the engine management that the faulty erg is working by freeing the egr motor from the valve or pluging the loom into a working egr, tied away under the engine insulation. Because the main challenge would be to pass MOT with tougher test requirements after April! This is al worst case scenario with the better acesss after removing egr pipes I think one should be able to clean the valve somehow and prevent it failing?

Best would be a software solution, and I might investigate that one later. But there is nothing now, no commitment from anyone to solve it soon, so not a lot of options.

I think it is better to blank the EGR between exhaust side and the Valve itself as then it will not get dirty. As long as the EGR unit is ok, you will not get any issues with the MOT. RRS SDV6 HEV Dynamic

Never trust the fuel consumption computer measure it at the pumps! What part of the enige did they clean?

Remind me again how does the coolingmist work, because cleaning the parts I took out was very difficult , oil and soot mixture forms a grease/ tar deposit, would have liked to clean the inlet manifold on each bank of cilinders but it's part of the tappetcover so to much involved but could see additional flaps in each track and all surfaces covered in the deposit, interesting the deposits only start after the ports of the egr pipes in the inlet track in the direction towards the cilinders so clealy comming from the exhaust gasses.
