Engine ECU repair/replacement


Recommended Posts

2010 Legacy euro 5 diesel..engine exploded and had no luck finding a decent low mileage unit . I managed to buy a very low (32k)euro 6 Forrester lump. With a few mods ,it fitted , but in the process I managed to transpose the loom from the ecu to the fuel pressure regulator/sensor...It does run ,but takes a fair few turns to start up. Fault codes are p0088--p0089--p1234--p2635. I have tried many "ecu specialists" but not one who will give a reasonable answer.What to do next is my question? attempt a rebuild with maybe up to £600 or buy a second hand ecu ,try and get the keys coded etc ..after all this whichever ecu is fitted will need the injector correction codes rewritten..thoughts and ideas please.

They are all pressure related because the loom to the pressure sensor had the wires put in the wrong position..2010 engine loom connections are different to 2016.

Currently using a Legacy loom on a Forrester motor .The Forrester has a different ecu block different injectors ,fuel rail etc.

I know the ecu is spiked, just need a company who are able to repair or as I said ,can I go down the s/h ecu route ,re learn my key info or do I need a key bundle.If a s/h ecu can be the way ,is it dealer only?

I say the ecu is spiked because I have a power from the ecu, an earth, so 2/3 there but I also have a permanent power on the reference wire ,hence the fault codes. P2635 is a stuck SCV apparently

The complete engine was swapped except for the turbo as the original is fitted, as the intake pipes are different.
