Hi
Ok, so in the dry, perfect, if I do about 20 miles in the rain it goes in to the reduced engine performance, Maf sensor error, so the RAC say, changed sensor, same again, air filter dry, also air box dry, but maf feels a little moist, all pipes are fine, so where is the moist air getting in, RAC moved the air pipe errors cleared, less rain drives perfect, any ideas ?

Thanks

Sorry 2009 model, xs, manual, 70.000, new crank and cam sensor, fuel filter, the full service

I have a problem 2008 model. The rain gets into the loom behind the battery tray into the fuse box behind the glove box inside. I would check the rain sensor as well as it only happens when it senses rain. Also the loom under the air filter housing is prone to damage by people changing the air filter. Another area is the scuttle drains, each side empties to the wing drains if not blocked. Plenty to keep you busy there. Hope it helps you.

Will take a look, thanks for the tips
