Passat Coolant Leak

[murraymac]

I have a W-reg 1.9TDI (115bhp - chipped to 130bhp). It has started losing coolant - fairly quickly. It only leaks when running - i.e. can be left for two days without dropping at all.

The garage have tried a couple of seals - but had no luck. There's no visible signs of leakage - possibly because it's hidden under a plastic cover somewhere.

Has anyone seen this problem before? Any advice would be very much appriciated!

Cheers,

Murray

I've had trouble spotting the leaks at the plastic flanges where the radiator & heater hoses join the cylinder head. They tend to get small cracks thay you can't see until you remove them.

I have had the same problem and finally find it is the water pump broken

dude, that sucks,

I had the same problem with my car and when i got it fixed they said it was the housing for the thermostat. It costs like $180 to get it fixed, but i havent had the problem since then. The price sucks to get it fixed but unless u wanna pay $10 every 2 weeks on coolant its not bad at alll.

Hi, pay also attention to possible heater matrix to be replaced. good luck.
