Well ,,,,,, I can underline the plenum relationship as spot on.
My newly acquired Tourer has been serviced and other anomalies ironed out since I got her last Saturday and today I just left the house for a long weekend jaunt.
I just went around two corners near to home and up pops a nice fat E on the display and the car loses all power and refuses to pick up.
I manage to coast into a handy lay-by and turn off thinking what the hell now!!!
She would not restart just turn over.
I then remembered this very thread about cutting out and thought,, we’ve had a lot of rain today, let me have a look in the so far unchecked plenum,,,,,,Well knock me out!!! It was 3 inches deep, everything soaking wet!!!

I commenced to pull out the ECU and disconnect it, there is also a white box that was full of water!!!! This I gave a good shake out and dried it off as best I could, I found a sock in my luggage and used it to dry out the black box and wiring, then reconnected everything and said a prayer!
Well God must have been at home as the car fired up first time, no E on the dash and off I went to 50 miles without further issue except to say that the car drives so much smoother and acceleration has improved immensely.
I wonder if there has been some water issues all along causing rough running issues and intermittent power loss.

Suffice to say Clean Your Plenums Before Anything Else!!!
