Today I wascleaning the engine bay of my audi a4 b6 and found some leaks.
Anyone know what this could be and what I need to fix it.
Thanks.

Not 100% clear on what I'm seeing on the picture but it looks like a pink crusting. If you are running G12 engine coolant, pink crust on the engine = dried engine coolant. Probably a coolant leak.

 

I magnified the pic, it looks like the insert for the engine coolant temperature sensor by the firewall is leaking, you can see an accumulation of pink crusting right on the vertical hose, by the clamp. Now I'm pretty sure, engine coolant leak.

 

Hi x1rider,
thanks for your quick response, is this very serious?

 

If you don't have time to fix it right away, keep an eye on your engine coolant level in the expansion tank, make sure it stays high enough. I would fix it as soon as possible though.
