It was a guy who is a trader - he trades from his home and deals with a garage, but he is a registered car trader - my receipt has his trading name on.
Anyhow, when I found the leak 3 days after I purchased the car, I mopped it all up myself and hoped it was just lots of snow that may have fallen in..so I didnt contact him until a week later (i'd had the car about 10 days by then). He was OK and checked the car out - poured a hose over, that sort of thing. Told me he'd found the leak and sealed up my rear bungs - or whatever they are. Told me, that once sealed they'd hosed it and no water was coming in. Sorted...or not, (this was Monday). By yesterday, my car was a swimming pool again, and since overnight, its got a massive puddle sitting ontop of my passenger carpet towards the back all the way to the front.
I'm so fed up, I have contacted Renault who are going to do a diagnostics on where the leak is next Friday. They told me I must be carful of the water as it could upset the electerics. So Im gonna be spending all wkend towelling up the water.
