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.
