I've read a lot of info suggesting that you can't turn down the egr via vag com for the PD engines This is a myth (well maybe on European models) as I just did it and wow what a difference it makes. I found out that ross-tech says it isn't possible because they are under the assumption that the PD engine is using the bosche EDC16 chips, but the Cupra diesel has a EDC15P and it allows you to turn the egr down to almost nothing. I've found that this now mean I can trundle around, in 5th doing nearly 30mph and the car no longer grumbles or feels like it will stall. (I don't always drive like this) Of course if I want to take off I still change down as not to kill my clutch. This has mean that my revo'd curpa diesel is now averaging 58mpg around town. Before I was lucky to get 40. It just feels so much better and instant on the off. Also there seems to be less smoke as the turbo spins up. I just followed the online guide and can confirm it works. This is the guide * To perform the following adaptations (except idle) you need to use the Login function. * Enter 12233 as a Login code. * Misuse of some of the adaptations can lead to engine failure. * This is done at your own risk! * Note that the EGR setting is for off-road use only... [Select] [01 - Engine] [Login - 11] Enter 12233 to activate special adaptations, [Do It!] [Adaptation - 10] [Channel 003] Give the throttle a tiny press and keep it like that. You will see that it currently reads around 220 mg/h Enter the new value 33768 / replacing the default [Test] Observe the "test value" field to make sure the adaptation setting is acceptable. [Save] You will see the this figure go up to around 330 mg/h and the % drop. Ok so I haven't completely blocked it off but this will prolong the life of my engine / save me money and it is completely stock. ( no block off pipe and no errors ). Sorry environment., but I'm already being good with CO2, being a diesel. Happy chappy and looking forward to my new suspension and brakes arriving soon.
