hi guys just thought ide post this up,ive seen many people say they have a mystery water leak on the mk2 focus well i found mine and it wasnt what i expected.
if you open the boot you will see under where the spoiler sits theres a plastic panel that pulls off well under that you will see the top of the rear window now push on it and see if it moves away from the bonding mine did as well as the spoiler bolt holes leaking so all off to ford today as its under warranty the rear glass was removed and re bonded and the spoiler removed and new seals fitted.
when the window leaks or the spoiler bolts it runs down the interior plastic trim to the back of the boot trim it then drips down and gets under the rubber seal making its way through any gap and finally to the boot floor top tip get some cheap gutter sealant and apply it to any suspect areas on a day when you know it will rain the sealant wont dry instead it shows the water leaking past it if it has dried thats not the source of the leak.
and another thing genuine mudflaps for the mk2 are a real pain in the axxe to fit the mk1 was a ten minute job not these difficult sods but there done now after a good while of spitting the dummy and cursing
