The kangaroo is known and it is 99% -the wrong injection map.

 

As you probably know, on wltp, the measurements are made straight when you start the engine.

 

VW needs to keep wltp co2 at the same levels like they homologated the engine/car.

 

When the engine is cold there are 2-5 injections (at ~160bar) so that the gas particles should not reach the cylinder wall and condensate there.

 

Also that why the 1.5tsi engines are not reaching at normal temperatures in short time, because is used too less gas.

 

You can find the injection info in the ssp-555, the engine is forced to work in the stratified mode too early (and not homogenous mode) in order to have a low consumption, and from there is resulting the low torque/kangaroo.

 

hi again,

 

to check if new firmware is available for your ecu you can connect to vag.flashinfo.de and search your ecu part number (example: 05e906018ck).

there you can see latest version and you can compare with your actual one.

i have the latest: 1910, updated 6 months ago.

(the factory default was 0863)

now kangaroo is 90% fixed.

Hi,

 

here is the cause:

 

lean warm-up and extreme retard spark.

 

If VW will fix this then the engine and the catalyst will warm-up slower but the engine will work as it should. (no more kangaroo)

They will not fix this because it will result slight bigger CO2 emissions
