Got A corsa with eml light on, various codes fuel trim and lambda sensor circuit faults, upon unplugging the plugs there is an amount of oil in the plugs, oil had a look in others plugs cam sensor also has oil in the connections.

I'm assuming oil getting in to the loom via capillary action anybody else had this ?

Just going to have a look at ECU plug.will post back.

The oil switch is damp as per normal on these.

Cheers

Stephen
