    Several trips to the an independent garage later, I've still got water leaking into the driver's footwell [some mornings I find a small pond to mop up before I drive to work]. The water is collecting in the far corner around the accelerator pedal. The repairer assures me that he has blown all of the drain outlets and has checked the heater drain and bonnet cable housing. I am reluctant to let the garage have the car as the mechanic is at a loss and frankly so am I?
    I have studied the postings on this site but I need some advice please.

    Seems odd.
    Have you checked the heater intake drain yourself? Easy enough to do. Pop up the bonnet, remove the plastic grill and have a look.
    Apart from this, you could have a blocked sunroof drain (if fitted) or perhaps a leaking heater matrix. (Does your car lose engine coolant?)

    Welcome to the forum Nottsmerc, have you had a new windscreen fitted recently? this could be a cause. Also a way to check your drains is wait for a dry day(if we get one) and use a watering can on 1 drain at a time and see if it produces any water inside.

    Many thanks

    Thank you for the swift reply. Just spent the morning doing prep for the next 2 days so I'll deal with it after boxing day.
    Merry Christmas!

    water in drivers footwell

    Hi
    No sunroof - just a 4 door 220 CDI saloon. Also I checked with the previous owner and the car has never been fitted with a replacement windscreen, so that's ruled out. I can't understand how it could be the heater drain as the water is collecting on the accelerator pedal side - opposite end to the heater vent. It has occurred to me to contact 'Merc' to ask if there has been any recall for this problem? It seems so out of character for this to happen on a car that must have such stringent quality control when built, despite being the previous model.

    Some early 203's left the factory with some welds that had not been done on the bulk head in front of the screen

    If it's a w203 built between march 03 and oct 05 the fault is : the top side of sealant used to stick the windscreen to the chassis is just 2-3 mm as a computer fault. It my sound silly but this was on both of my Cs and this is what MB Romford said. Pay £60 and claim for a new windscreen from your insurance.
    Another explanation may be the drains blocked by leaves and dirt.

    If the heater box drain is blocked it is better to clean it out and cut the flaps off the bottom of the drain

    thanks

    My thanks to all for the advice. This site is brilliant and a must for a merc owner.
    Car is now with a trusted mechanic in S/Yorks and he has just fitted a new Bonnet cable - said the bulkhead seal was US.
    I do however think that the windscreen advice is the next line to take if it still leaks. Surely this must be a recognised Merc fault?
