[QUOTE="Cowabunga, post: 7319372, member: 718"] Your pickup probably had EGR 20 years ago. Everything of that type with a Diesel engine since 1993 have had EGR and from 1998 a Cat. From 2008 on, many had DPF as well. It was an extra cost option on a 2006 Audi Q7, because I remember declining to order it on my new car back then. All a modern engine needs to get warm enough to regenerate the DPF is about a ten mile journey under load at about 1500 rpm to 2500 rpm. The far greater power density of modern engines may give the impression that they are lightly loaded but if driven at the same speed as those old 50 to 70hp engines, they will be loaded and produce plenty of heat. The issue with DPF's is that some just potter around and never get a chance to get hot and that some inferior designs have the DPF mounted remotely from the engine, where there is excessive heat loss by the time the gas reaches the filter. You would have thought that car designers would have known this after many years of experience with DPF's, but some still make a dog's dinner of it. Up until earlier this year, all JLR's new Ingenium Diesel engines fitted transversely had, indeed have, massive issues with poor DPF performance, repeated failed regenerations and subsequent dilution of the sump lubricating oil. The same engines mounted in-line in Jaguar F-Pace, RR Velar and Discovery5 never has this issue, because there was room to fit the DPF to the side of the engine directly mounted to the turbocharger. That is not to paint all transverse engine vehicles with the same brush. I have three such vehicles and I wouldn't have bought any of them if the DPF was remotely mounted down the pipe. [/QUOTE]
