hi there ive just got a 1994 audi 80 2.0 and the temp gauge does not work the fuel gauge was going up and down replaced the voltage regulator this fixed the fuel gauge but not temp gauge . i have noticed that there is two sensors at the thermostat housing but dont know which one to change any help would be great.also i am only getting about 20 miles to the gallon which to me seems quite low.

hi.
replace the white 3 contacts sender unit and you are good to go.
as for the consumption i would check spark plugs, air filter element and throttle carbon build status (if you know how..).
best of luck.
