Water Ingress

[David Price-Evans]

I have a 2010 Mercedes Benz E200 CGI Blue Efficiency Sport 2dr Tip Auto 2010 I am getting water in the rear footwells and it drains out from in front of the rear wheels. Its been into a Mercedes garage and they could not locate where the water is getting in. Has anyone had a similar issue or know where I might start to locate the problem

Many thanks, David

Is it a cab/coupe or 4 door?

Opps It’s a 2 door convertible

The drains in the sills are probably blocked. Common issue. Water is designed to flow through the car, into the sills and out through the sill drains.

Many thanks, Alex

I have checked the drains they look ok and water is freely collecting under the car from the front and back of each sill. The water seems to appear when drenched with a hose in nearside rear passenger footwell. I could not see any water ingress from window or roof seals so it's still a mystery?

I take it that these don't suffer from water getting in through vents behind the rear bumper, like in the case of some models?

Perhaps a smoke test might establish where the leak is?

That's might be the answer as the water is in the rear footwell

That's a great idea
