Thread: There's always going to be talk of EGRs.

Everyone hates EGRs. Here's a different view.

Neato. I agree completely.

The reason I "deleted" the EGR is in a EU4 Discovery with DPF both the DPF and EGR are built in such away as to ensure if it faults 2000km from home, you're essentially ****ed and have to limp back at 40kph on the bump stops. Slower with a van on the back.

After limping around several times over several weeks (and 40kph on the stops isn't fun in freeway peak hour traffic with 2 screaming kids in the back) I removed them both.

Yes, prior to removal I had the guilty EGR valve replaced and yes had thousands of trouble free kilometers until the DPF faulted and I was back to 40 kph on the bump stops. The problem is wanting to go to remote locations, I also wanted to know I was going to be able to drive home again.

So he's spot on. If the EGR/DPF had been designed in such a manner as to say "there's an EGR/DPF fault, if you perform these 30 incantations using the stalks, steering wheel buttons and dash buttons to bypass the fault" we'll let you continue then I'd have been happy leaving it in place. You know, make it a bloody inconvenience every time you start the car, but at least let you continue safely and reasonably. If there was something like that available where when it gums up you can still drive home, then I actually wouldn't have removed the DPF or the EGR. Unfortunately, as the car becomes "problematic" if either of these complex and dirty systems fail (as they do) then it was easier to re-program the ECU, block the EGR and gently attack the DPF with a small cut off wheel on a 4" grinder.

I simply removed them because those 2 systems made my vehicle unreliable. The DPF made it completely smoke and odour free. It was in fact the "perfect" diesel. Unfortunately given the choice between "perfect" and "reliable", I choose the latter.
