Audi Repair: Audi repair, coolant tank, coolant leak

Question
My Audi 2002 Quattro 3.0 board computer reminds me to add up coolant once a week. I checked all connections they are dry. When I opened the hood I felt the smell of burnt liquid. The oil level in the engine remains the same and the color is not changed. CEL is on. What can be the problem?

Answer
hello
On many 3.0 engines I have seen coolant leak coming from nipple on rear pipe which connect both heads. It's right under coolant tank on l/side. You can replace just the washer .
CEL - you will have to find out the fault codes first.
good luck          Greg
