The gearbox has nothing to do with P0013. Look again at the downgrade modes of this fault in the explanation I provided on the previous page:
  • Change to butterfly mode
  • Deactivation of the adaptation of the exhaust camshaft
  • Deactivation of the adaptation of the basic richness
  • Deactivation of checking of the canister purge
All the above are going to affect the running - there is an open circuit somewhere that is causing the specific fault code that results in the the above listed actions.

No worries - it happens when troubleshooting issues.

Oops! Don't worry too much about it; you aren't the first to have done that and you won't be the last. However, it is likely (because of what your family have said about you) you will not make that sort of mistake again (just in case they say "I told you so").

So to get back to your real symptoms, can you give a better description of how (and when) the engine is running badly? It is currently a bit vague.
Was it already like this when you bought the car?

ok start car with all connected rough idle cuts out
diconnect vanus solenoid does not matter which side ,start car ,runs like a watch .
you can reconnect vanus as soon as car starts and it will be fine until you have to start it again,
hope this makes sense as it does,nt to me...

It is likely that if the engine is started with a solenoid disconnected, the ECU will not enable the vanos operation until the next time the engine is started.

Was the problem already present when you bought the car?

I I do not know the capabilities of you SnapOn fault code reader, Diagbox can often read fault codes that are not seen by generic readers, and can read live data from the ECU that should give useful clues.

As you have replaced the vanos solenoid valves, you could try disconnecting the electrical connectors from the ones on the engine, and connect the old solenoids to the cables, this will fool the ECU into not throwing the open circuit fault code, but should leave the valve timing in its default state, to see how the engine runs.
