Have had audi quattro TT. 3.2 2006 model for 1 year. Have heard sloshing of fluid/ water under floor for about 1 week. Checked carpet which was completely soaked at the back drivers side. Front driver side also wet but seems even worse at back. took it to quick fit for opinion. Thought it might be split drainage pipe from AC unit and said if so the whole dashboard has to come out for access. He did not lift carpets or remove anything to check. Can anyone help. I am a female owner and do not want to get ripped off. Does anyone know what it could be ,does that theory sound reasonable and where is good place to take it. I live in west London. Any ideas/ suggestions would be appreciated

It could be that your sun roof drains are clogged and its causing water to get into your interior.

Search around the forums for similar incidents and you'll probably find more information.

Good luck!
