hello . Will it be possible to use AJM (pd115 , 1.9 tdi ) ECU and harness with AVB (PD100) engine?
all suggestions and answers will be helpful .

hmm

it's almost the same ecu's, but they can have different parts for extra car equipment, like climatronic (eg. 2 sides) or extra electric interior heater, etc.
There also are some diffrent in PD version's, 22.0; 22.3 ( i dont renember right version numbers)

Also AJM and AVG are engines symbols, but engines can have diffrent ecu number like:

- 038 906 019 AM
- 038 906 019 CJ
these are only for AJM

best way is to find exacly number np 038 906 019 CJ for yours 038 906 019 CJ

these last 2 letters are important!

Thanks for reply . i'll swap engines ( 115 to 100) seems that most of harness matches . gonna have pd 100 engine with all harness and extras from pd115 :)

That shouldn't be a problem.

I had a Fiesta 1.4 16V Duratec with an engine and gearbox of a Fusion 1.6 16V Duratec. Only raw engine and gearbox were changed.
