Electric sunroof - water drainage

[exec406]

Anyone had electrical blips due to water build up in the sills?

Found I was getting a build up of water in the sills if the car was parked even slightly facing uphill. This then seemed to trigger the 'engine anti-pollution' limp home mode. The ECU would then realise it was not a serious fault and give
you the 'engine' power back. Fault light would still stay on for a while.

What I've found with the sunroof drainage is that if you park facing slightly downhill, the water drains well out of the front two drainage holes with no build up in the sills. Anyone else notice this? Car is a 2003 2.2hdi Exec.

Thanks for that, I've only had water coming in the cabin during heavy rain showers and this was a small trickle at the alarm sensors on the A pillar.

Got that one fixed, it was water getting in via the radio antenna. Go this sealed better and haven't had that issue again.

I think with mine I may have the rear draingage holes blocked, every now and then I make sure the front drain holes are clear of debris.
