Stocky / Stoneyford
why are you not at work ?
I am no expert on the subject but this is how i understand it.
PD 140/170 both have the same 2.0L ( 1968cc ) engine controlled by EDC 16 ECU.
PD 140 does have a FMIC (on the Audi and Golf anyway ) sandwiched between the air con and the radiator. Quite a nice big FMIC actually but with smallish pipework but that can be enlarged without to much hassle.
The main physical difference is the use of PPD Piezo-Pumpe-Düse piezo-electric injection system which are different injectors again to the PD 140 which have different injectors to the 1.9 PD engines. The newer injectors get more power from the same amount of diesel by having a different spray pattern and even more control on the amount of diesel sprayed.
"The engine’s turbocompressor geometry has been improved" basically means they have altered the angle at which the turbo is set off the engine.The turbo is also at a different angle on the 2.0L PD140 to all the 1.9 PD engines which means all the hybrid turbo set ups for the 1.9 PD engine have to get a custom turbo manifold made to get the turbos to fit, plus all the oil feed lines etc have to be altered.
I have not found any information if the turbo is different but i doubt it myself.
If anyone knows and can prove i am wrong about any of the above information please feel free to prove me wrong as i already stated i am no expert.
Tuners are unlikely to have much if anything for the PD 170 ( other then maybe a remap in a few months ) since it is so new and tuners rely on having some dumb ass customer who don`t care about having a warranty on a £25,000 new car so that he can have more power.
