Coolant leaking

[kozmos]

Within 10 months of owning my S4, I've had issues with coolant leaking issues.

First was a cracked expansion tank. This was an easy fix. I just replaced the expansion tank.

Now I've got another leak and this time a little more serious than the last.
The leak looks like its coming from a hose under the TBB from what I can see. Although I cannot confirm the source of the leak (BTW, car is now in the shop for repair).

My car only has 33,000km and fairly new. Is anyone else having problems with coolant leaking issues?

Sounds like the turbo coolant pump under manifold may be cause of leak.
Seen one coolant pipe leak in this area due to perforated weld but only once. Both req removal of manifold.

What was cause of expansion tank crack?? V low miles for this.

I had the same thing, look down the back of the engine with a torch and see if you can see water around the back too.

Mine was the After Run Coolant pump. I managed to go on holiday with mine but it slowly got worse. I had east kent Audi replace the pump... about £350 inc Vat and the labour.

Now its fine, but I either have a new problem or they created another problem. Will be posting something soon.
