Experts,

I have discovered that my 2004 1.9TDi Passat has developed a small water leak. I only realised that I had a leak when i noticed that the expansion tank needed topping up.

I think I have located the leak. It appears to be a very small trace of water coming from the bottom left hand corner of the radiator (as you look at the car front on). Not much at all, just a small show of water.

So, a few questions:

Are Passats prone to leaky radiators generally..?

Is it likely to be a leak on the radiator, or would it be more likely to be the pipe connections to the radiator...?

How much coolant does the 1.9TDi engine actually hold...?

Has anyone else encountered similar problems..?

Your help is much appreciated....

Regards
