Audi A6 2.7t overheating
Any help would be greatly appreciated!
My 2001 Audi A6 2.7t started overheating after half hour of driving, i have HOT HOT HEAT, no coolant leaks, but feels like half the radiator is cold??? Is there air in the system or does it need to be bled? How do you bleed the air out on this? Or maybe a bad water pump? Stuck thermostat??
But how can i tell if the water pump is bad on this car? Coolant is Clean and oil level is fine! I never let it get to the "H" mark soon as it got 2 marks past the middle, i turned off the engine! Please someone help! thank you!

Future Consideration - Preventative Steps
Hopefully the engine problems associated with your Audi A6 were solved. In the future, scheduling maintenance appointments will often nip minor issues in the bud before they become major detriments to your vehicle.
As we get into the warmer months, antifreeze/coolant condition is still important. In addition to preventing freezing in cold months it also helps prevent your car from overheating. It also lubricates the water pump and prevents corrosion of the cooling system and heater core. Most manufacturers recommend changing the coolant/antifreeze every 2 years.

Thermostat, et al.
Yep, I agree with the diagnosis ... most likely a thermostat issue. To replace it, you've got to put the car into service position and pull the accessory and timing belts off. When you replace the thermostat, and the accessory belt, and the timing belt (you are planning to replace those, right?) you'll definitely want to replace the water pump and the various belt tensioners while you're in there. The additional parts expense and labor required are almost nonexistent compared to the fact that a) you're right there already, and b) one of those things goes bad (and they will) and you get to do it all over again.

Addendum ... about the thermostat and coolant
One of the fastest ways to ruin a water pump is to use tap water. Use distilled water, along with the necessary proportion of *good* coolant, like G12-Plus-Plus ... the purple bottle.
I should also add, when I pulled off my thermostat, I found a cigarette butt jammed inside it and I don't smoke. And, the label on the butt was for some cigarette brand popular in Germany. I'm guessing while they were putting the engine together on the assembly line, someone ended their smoke break by flicking the butt at my engine. Dicks.

Start Small First you could be wrong!
I have 171,322k Miles on my car and changed both water pumps, timing belts and etc at 110k
I am so tired of everyone blaming the water pumps / thermostat / bad heads etc etc when there are so many sensors that you need to check first before you take the front end off to play with the timing belt.
I had a issue on my 2004 Audi 2.7t Quattro where my car was showing it was overheating on H and as everyone here said so did so many mechanics locally change your water pumps and thermostat one even told me .
Well folks my laser thermometer showed coolant temperature was 200f and radiator and lines were 200-210f so the car was normal , I then changed out the Temperature Sensor and Sender. Problem Resolved, Needle on gauge was back to the middle.
So before you advise someone they need to spend thousands playing with the timing belt or hours wasted on changing parts, start with the sensors quick and affordable.

Question about the sensors
How quick and affordable is the sensors to replace?

I believe that this might be my problem. My Audi’s temp light came on but the car didn’t seem to be overheated and after getting it home my husband played around with the sensor. I have ordered a new one so will give that a go. Just makes life difficult as we live rurally and only have the one car between us at moment.
