Hi,

i have install a 2006 Golf MK5 R32 Motor in my Golf MK4, but i have errors.
My ECU ist complete original but i get errors, but I don't know why.
I have wired all cables correct and messured them already, but there are no errors.

My ECU tells me some errors.

17072/P0688/001672 - ECM Power Relay Load Circuit: (J271): Open Circuit
-> but all is wired correktly and all fuses are OK

16725/P0341/000833 - Camshaft Position Sensor (G40): Implausible Signal
- Wires are checked an ok, I also have changed the sensor, checked the timings but there is no error

and i get a lot of other errors because the control units like MK5 Dashboard, ABS, ESP, Airbag are not installed.

Because I have checked all wires repeated and I can't find the error there, the faulty must be the ECU.

Does sombody know how i can fix it?

can you connect to ECU? i believe realy 19 is gone

the P0341 error looks like a timing problem or the engine have mk4 vanos build in.Check the timing again and looks from the exhaust side to the marker.
