Default 407 2.7 HDi V6 Diesel Remap + EGR deactivation

Hi All,

I am still getting the Depollution fault on my car and following the error codes it would appear to be an EGR valve issue (Fault codes: P0405 & P0407).
I have been looking into Diesel remapping as most of the websites state they can deactivate the EGR as well as remap.

The costs are around 300 ish, would it be beneficial to get a remap done? Would it stop my depollution fault if the EGR was deactivated via a remap?

I know I should probably just get the EGR valve fault fixed instead of using a work-around, but I like the idea of a remap anyway to get better BHP/Torque and MPG 'apparently' and also solving an annoying error message as well...

Has anyone who had their diesel remapped comment on the benefits vs cost and has anyone had the EGR deactivated via a remap?

Thanks for any help,

Paul

problem with remaping is if it is done properly then there should be not faults present as if remaped with faults you will always have problems with these codes popping up so you need to fix the fault first then get it mapped

But if the faults were to be cleared and then the EGR was mapped out, then surely the EGR wouldn't be active, so therefore the faults can no longer occur?

well I dunno I don't do remaps but I know the place I use always tell me if there is a fault get it fixed and drive it for a few weeks before I get it remapped otherwise there will be problems

If it were me I'd just get the EGR valve fixed or replaced. Does such a powerful car need a remap?

I've got the same car. 407 2.7 hdi. I gotta admit with 205 bhp and loads of torque, do you need a remap?

Of course you do!!!! More power!!! Anyway, you should see more gain with egr blank and dpf drilled, mapped out. Add a full remap on that and yeah baby!!! Keep updating if you do go ahead!! Personally, I say go for it!! :-)

Thumbs down

Its quite a relatively sharp powerband fora big capacity diesel so I reckon it'd benefit nicely from a quality remap.

I could certainly do with a bit more urgency off the line. Once the revs get up she goes ok but there is always a heart stopping pause especially when trying to nip across traffic etc. I'm presuming a good remap might help in this area?

I hate this so much, it's a horrible feeling when I put my foot down and not much happens.

I'm going to attempt to clean/replace the EGR first but think I am going to go ahead with it, remap and EGR deactivation at 260.00 sounds relatively good price to me. Will post results after completion.
