Hi.

I need your help and advice guys.

I have an XC70 2006 D5 , has fault codes , Injector power stage on Injectors 1 2 3 4. 2670 2680 26B0 2690

Fault comes randomly , but mainly when warmed up and causes a misfire and lack of power , car seems to hunt when crawling and RPMs fluctuate.

I have replaced the terminals at the injectors connectors but that did not solve the problem , the loom is fine too.

Could it be an internal ECU issue ? I m thinking to get a replacement ECU cloned.

Any help or advice is much appreciated.
