What ecu do i need ??????

[honingkoning]

Guys i have a vw polo year 2002/2003 Car have been in several garages and now its with me.
Customer changed ecu ( ori ecu not avail)

Engine 1.4 16v with code AUB, they fitted ecu with Numbers 036 906 034 BB, i made ecu virgin and reprogrammed Car running bad very bad, check all mechanic parts (compression, Ignition etc etc all ok )

I Checked on Other polo in workshop with Same ecu but this is new engine with 4 igniter coils but ecu is the Same,
The Car that runs bad have one Ignition block on the rh Side of the engine.
So i suspect this ecu is not good for this engine.
Now i need to now what ecu i need, i found some old ecu from Seat cordoba with engine code AUA.

Could some one tell me what ecu's would fit to this Car.
Dash have immo id so it ahould be immo 3.

Do you know if this is immo 2 ecu? I have some spare ecu 036 906 034 D from AUA motorcode.

Do you think this Will be ok ?

The dealer can get you the right ECU p/n by VIN. There are too many factors (production date, country, emission, transmission), which are unclear.

You need the correct flash to run your engine. Once correct flash is in it should run ok

Guys if i transfer immo data and right flash the Car should run right?
I cant see any difference in hw between immo 2 and 3 (except new ressistor instead of the old with color bands)

Is There a difference you guys know.
