Water from under the dash? I suppose the wipers are the most likely route. The rubber seals rounf thewiper shafts on Aldermog are a bit "tired" as are the screen wash ones. Something for the winter as the dash will have to come off I guess.

Can you not fit a heat resistant shroud over the wires and Lambda sensor to try and stop water from getting at them? Not sure where yours are on a Roadster. mine are at the case of the exhaust manifold and mounted vertically on top of the pipes, but are shielded by the chassis and side wall, it might be possible for water to get at them if I went through a deep puddle with a big splash.
