The emissions fix ruined my SEAT Leon - can Volkswagen reinstate the old engine remap?
I've had the emissions fix done on my SEAT Leon and now the car is a dog. Can Volkswagen reinstate the old engine remap and remove the flow obstructer from the inlet? The car is doing 15 per cent less MPG, the EGR valve is constantly cycling and the turbo boost is reduced and laggy.

Apparently not because it isn't simply a remap. A number of obscure codings are changed. Some owners have found that switching to superdiesel sorts it out due to the higher cetane suiting the new injection cycle better, so that's worth trying.

Quality and refinement are impressive. Great to drive with sharp handling. Shares same base as contemporary Audi A3 and Volkswagen Golf.
