Can anyone help me understand what this means is disturbing the A6's engine and what it takes to fix it? According to the temperature gauge, it is not overheating and I have temporarily connected the wires so that both fans run continually when engine is running, but the red warning light sometimes flashes on the dash. Code is P1408 Audi

Can you help me understand what this means and what is needed to fix it. Code shows P1408 Audi, temp gauge does not indicate it is overheating and I have temp fixed wires so both fans run when engine is turned on - still red temp warning light sometimes flashes in dash... What happens if, after loosing most of the red coolant through a leaking hose, small hose connects right next to front motor mount, fixed leak, I run it with water in it until I am sure it is fixed?

What model and year is your Audi? The code is not related to the cooling system (radiator fan, radiator, engine temperature), the code is for Exhaust Gas Recirculation (EGR) Temperature. Totally different problems.

Oh yes, sorry about that! This is a 1997 A6 Avant, quattro. So this is EGR!? What does this mean? What is needed to fix it? Thanks for your input!

You have to replace the EGR temperature sensor. Before you replace the sensor, you could try cleaning the EGR valve and sensor first.
