Wonder if anybody has had this problem.

I can hear water sloshing about in the car when i accelerate or brake. It seems to come from the cabin. No water in any of the doors.
Water has considerable inertia so appears to be large volume. A body specialist advisd me to remove the drain plugs in the sills, but having looked there aren't any??

Also and unrelated to the above the 'antipollution fault' text appears on alarm screen and engine management light comes on. My service agent checked it (£45) and advised me it is possibly the coil pack (£120) The car performance isn't affected and iam just a bit worried that replacing the coil pack will not cure the intermittant fault and i'll be £120 out of pocket.

Any help would be appreciated

cheers David

Sills would be the most likely place for a build-up of water. There should be several drain holes per side - maybe yours was over-enthusiastically chip-coated and they've been sealed. Can you find a similar model and see where their holes are?

"Anti-pollution fault" is a generic fault message; what actual codes were found? Coil faults are rarer on the RFV engines than on the smaller ones. Usually you'll notice a misfire if one is going.

Thankyou.

I jetwashed the cars underneath yesterday to remove all debris and sills are smooth as the preverbial babies.. No signs of any plugs at all. I will check another 406 (and try not to get arrested while im doing it).

Don't have any misfires or problems with the running of the car, but the garage said it had found four things which point to the coil pack. Bring back dizzys and points, these were only £2.50 a shot last time i replaced anyway!

You will have to stick your head under the sill, the drain holes / slots are hidden behind the lower lip.

Should be 3 along the length of each sill.

While you have your hands dirty, might as well check the door drain holes too.

Thanks Lee

I got my head and my hands dirty today going along the whole ofthe sill with a bradall, pushing and probing but no joy. Absolutely solid underneath. I did however then decide to drill a hole in the middle and watched 4 pints of water trickel to the floor.

Was mentioning this to a friend today who also had a 406 and he tells me that he had exactly the same problem.

Not had it before on any of my numerous cars so i suspect the 406 must have a bit of a design problem!
