First post on here for a few years. I've since bought my second Fabia. 2016 65-plate, pre-FL hatch, SE L trim, 1.2 TSI 110PS, 6-speed manual.

This has been trouble-free until last December when the driver's door window regulator failed, and was replaced.

The problems now:

1. Water leaks under the driver's door when it rains, and pools in the ridge of the seal on the sill.

   • I think this happened once or twice previously but seems to have got worse since the window regulator replacement

   • Seal looks in good condition all round

   • Off-street parking space outside my front door is on a slight gradient; driver's door facing uphill if parked with boot facing front door

   • If I park the other way round, I don't get water leaking (driver's door facing downhill)

   • But that's impractical - reversing onto the street is trickier; the boot isn't facing the front door which is less than ideal when loading / unloading

   • Most (but not all) of the water pools on the rubber footwell mat, but I keep having to remove the original mat from underneath to let that dry out (luckily this happens easily if left in the house to air overnight)

   • Wondering what adjustments can be made to door; puzzled about where the water is getting in. Could be handy to pass back to mechanic

   • I've noticed a bit of the black glossy trim over the B pillar on the driver's door has slipped down slightly - possible reason?

2. Door card rattles, especially with bass from the speaker, but with motion from car too; clearly not quite reinstalled correctly after regulator replacement

   • Can feel a gap between the card and the door skin around the bottom as well

   • Just in case rattles persist, was thinking a layer of insulating foam inside the door card cavity

   • Road noise is an irritation after re-fit with this car, but can't work out where it's coming from the most

   • Would appreciate recommendations for sound insulation, and particular products / suppliers

   • Was thinking insulation in door cards could go in if the driver's one needs to come back off anyway

   • Hoping this might improve performance of stereo system a little bit (factory-fit Amundsen)

There are strips of what looks like deadening material against the bodywork in and around the spare wheel well in the boot; clearly factory fitted as these are sprayed in the body colour.

• Would covering this whole area in Dynamat, for example, be worth doing?

• Anyone used kits like this? https://www.noisekillers.co.uk/products/skoda

To me the problem sounds like whoever done the work to replace the window regulator hasn't put things back properly and that needs checking and putting right or reinstallation done properly. If you paid this person and you think you can trust them to do the job properly on second attempt then go back to them.
