NOxious Volkswagen diesel emissions scandal: Chief falls on sword


Re: Not all need to be recalled.

Having been sold a diseasel by VW and being quite happy with the driving performance, I'll not be at all happy if VW try to modify my vehicle to enable THEM to comply with the law. If it turns out the modification will steal power or is likely to result in expensive repairs not far down the line, the answer will be NO WAY. The engine uses EGR to reduce the combustion temperature to reduce production of NOx. This unfortunately produces lots of soot, which is collected and burned in the expensive DPF. Unless VW retrofit a urea based system, reducing NOx will be achieved by a software update to increase EGR. That will reduce output power and increase soot, clogging the EGR system and the DPF sooner than if the software wasn't updated. A simple software update versus the laborious installation of tanks of concentrated piss... Hmm, I wonder which VW will choose as the "fix" for their cheapskate design-and-cheat snafu?
