Re: drain holes
You might also want to check the concertina plastic pipes that protect the wires running between the A post and the door - one of mine was not actually attached - just looked like it was - and water was getting in there and filling up my footwell.
That was on my last 164. My current one also leaks, but also only when parked nose up in heavy rain. Think it is probably coming in through a heater vent, but can't gain access with the aircon gubbins in the way, so will just never park uphill.
Good luck. Wet carpets are no fun.
