intake manifold just beyond the throttle body
If It is the temp. sensor and not the thermosat I believe it is the bottom of the coolant tank. I thimk you have to buy a new tank.
on the A4's, they are typically under the front bumper cover closer to the drivers side.
There're two got same name, same spec, but different shape. One on intake hose/adapter to throttle body, it's called intake air temperature sensor. Another can see through from front bumper lower section, in front of air conditioner condenser, on the bracket of power steering cooler. It's called Ambient temperature sensor. If you don't see it, it's gone, the wire or connector is quite easy corroded.
Need to hook upto a scanner. Check for codes.

Disconnect the wires, and unscrew the O2 sensor. You might want some wd-40 to soak up the sensor's threads before you try to remove it.
I read on a diff site, that suggested there isnt one.. and that you unscrew the sensor and thread in a filling nipple.
where is the speed sensor for spedometer of Audi A6
not sure about an audi, but usually there are not alrm sensors on engine compartment on any vehicle , unless an extra has been installed by the owner
You should have gotten a letter from Audi about an extended warranty. The sensor is now covered for 10 years/100,000 miles for a falty sensor. This sensor (if malfunctioning) will cause the MIL to light up by "sensing" that the engine coolant is a couple degrees above what it should read. No Idea where it is but you shouldn't have to worry about replacing it yourself.
A bad brake sensor can cause the ESP light to stay on in an Audi. Other reasons the light stays on include a problem with the batter, loose clamp causing a leak in the intake, and worn brake pads.
Diagnostic error code number 118 with high temperature input on a Audi A4 means that the engine coolant is not running at the right temperature. When the engine is cold, it should be warm, and when the engine is warm, the temperature should be cooler in the engine. The problem could be with the Engine Coolant Temperature sensor or the vehicle could be low on fluid.
Where is the answer
