Force Volkswagen/Audi/Seat/Skoda to revert emission software updates

Volkswagen are making out that the software update is minor - but it has been independently shown that the updated software makes a dramatic change to the utilisation of the EGR valve. While this is the cheapest fix for Volkswagen to make, the engine was never designed to handle the increased soot loading, and is being made to fail sometimes within hours of the update being applied.

VAG Group dealerships are routinely applying the software updates without even notifying customers of the impact they may have, knowing full well that their customers will encounter reliability problems as a result.

The change to the EGR valve curves in the software mean that far more exhaust gas is recirculated in an attempt to low combustion temperatures, and produce less NOx. By doing so, the engine produces far more soot, which then clogs up the EGR valve, and DPF. Injector patterns have also changed, leading to higher duty cycles and again, premature injector failure.

When engine's fail due to soot contamination, it can cause sudden loss of power, which during manoeuvres, or motorway driving can be lead to accidents. People are afraid to use their cars.

Volkswagen are making their customers in the UK pay for their deceit by pushing an ill-conceived and hurried software patch out and hoping the problem will go away.
