Hi all,
Been trawling these forums for fixes for my 96000 mile E85 2.0i which has proved very helpful over the years, thanks!
My latest issue has me running out of ideas though. I have an engine warning light, slight rough idle & power loss, and fault codes 2A67 - 'valvetronic fault' and P1050 "Camshaft position actuator - exhaust, circuit open."
So far I've changed the valvetronic motor, cleaned, tested and swapped round the vanos solenoids (getting the same readings on the multimeter for intake and exhaust solenoids) as well as swapped round the camshaft position sensors and done an oil and filter change but still the codes reappear. 2A67 almost immediately and P1050 not long after accompanied by an engine warning light. Multimeter gives near as dammit the same readings from intake and exhaust vanos connectors for volts and resistance, though volts can be hard to get a reading for.
There was the smallest amount of oil in the eccentric sensor socket (presumably from an over zealous top up at some point) and a slight leak around the intake camshaft sensor (now solved with a fresh o-ring).
I am reluctant to fall into the trap of endless replacement bits without pin pointing possible issues so any suggestions of what to try next much appreciated, thanks!
