Hi All,
Just a request if anyone else has noticed...
I'm not a fast driver, will sit comfortably at 70mph in Eco mode on the cruise control. I do quite a bit of motorway travel.
I have notice over the past week, after the diesel Nox software update, my car no longer enters 9th gear on the flat or down long hills @ 70mph. I am now using my paddle shifts to compensate.
I believe the car is reving slightly higher, and one method of reducing Nox is by having a less lean-burn and a lower compression ratio. Which the engine-management system could effect.
The effect on the car was not explained by the dealer, and so has the car been de-tuned and become less efficient to reduce the Nox?
Would appeciate other's experience.
Steve
