Good morning all, 

I have had a Vivaro for the last 5 years but unfortunately it was on its wat to the big scrap heap in the sky.

I purchased another later 2011 Vivaro 2900 CDTI which had a blown engine, but also had a replacement engine which had not been fitted. The original engine was M9R786 the spare engine that has now been fitted is a M9R740. The problem is that the injector system are different? When you turn engine over comes up with injector problem. 

Can I just have the injectors coded or will I need to change ECU, module & key or am l just waiting good money after bad?

any help would be appreciated 😭

 

Hi...welcome to the Forum

I would personally try to recode the injectors first but if unsuccessful then it would be a replacement ECU, etc.

Keep us updated on any progress 

As above id say your injectors need coding to your van
