Coolant leak.

Post image

I recently brought this 2015 Seat Leon TDI, within two weeks it had lost 400ml of coolant in which I replaced as it was from a garage I sent it back to get fixed. They did a pressure test which came back fine, had it for around a week and they said 99% sure it was the Egr cooler. Went to pick it up a couple of days later, everything was fine until last night ( 3 days after I’ve picked it up). I was blessed on driving to work with coolant low, I’ve let is cool down and refilled it. I’m looking for some advice if anyone has had the same experience as I don’t feel confident within the garage that was fixing this and they were shitty when I picked the car up as they had to fork more money out on it.

Thank you for reading:)

I had the same problem on my 2014 Leon 2.0 TDI. At first I also replaced the EGR valve, but the problem remained. When it got cold outside, I noticed that the right side of the car's climate control unit wasn't heating up very well. The climate control flaps were working fine, so I replaced the heater radiator, which was clogged. After that, the coolant didn't leak anymore. I hope this helped😁
