3.6 EGR blanked and tuned out

[Graeme]

My brother's MY08 seems for a while to have been experiencing EGR problems (P065E-68 Inlet manifold tuning valve error bank 1 and eventual loss of power towing uphill along with some coolant temperature increase) so the option of blanking the EGR valves and applying a BAS EGR delete s/w update via his IIDTool is being considered. Any comments?

Certainly worth it Graeme. EGR deposits are 'satans snot' in my books😅

The reference to a tuning valve threw me for a while, wondering if there was some sort of inlet tract length change capability but soon realised the attempt to give EGR a name suggesting a more acceptable function.

As you know I have fitted EGR emulators, which have been good. But BAS EGR map out with remap is another good option. Their remap is cheap compared to others.

An emulator kit was originally considered but having since procured an IIDTool for a remote area trip last spring the s/w option is now cheaper.

For quite some time the vehicle has appeared to have overheating problems towing the van on long climbs, seeming to go into a low power mode which it may or may not have done but discovering the EGR DTC starts to explain the behaviour. No DTC occurs with normal driving so the valve must get sticky when hot.

The motor is quieter and smoother without the EGRs. I recently did a high tide, low range, extended beach run, fully loaded (after 'decamping') which resulted in everything getting quite hot. I gave it a breather when the coolant temp was getting close to the right/red side of the gauge. The fans were going full pelt. But not a hint of a fault. I was pretty impressed.

I think emulators helped as the tdv8 seems to dump more fuel in to compensate for EGR activity. Just my unqualified observation of black smoke out the back when the EGRs were working.

does excess diesel have a cooling effect like in petrol engine?

Exact opposite unfortunately 😮😮

thanks, i thought that was the case.

so the emulator puts in extra fuel (compared to having a real EGR).
which would result in higher temperatures?

I'd like to know if you do go with the BAS map whether they remove the egr in the map for you or not.
Pete didn't want to do a EGR delete on my 3.6 unless I mechanically deleted it which isn't just ab easy blanking plate.
