Re: 2003 audi a4 1.8t sedan temprature guage
You're talking about the coolant temperature right? If so, it's likely to be a coolant temp sensor. They're known to go bad on the A4, and they're only around $20-25 from www.ecstuning.com. If you replace it and the problem isn't fixed, no harm done - sooner or later that sensor WILL go bad. The result is that most likely your thermostat got stuck open and will need to be replaced.

theres two plugs on the fuel pump. one is for pump and one is for gauge if you take pump out of tank and put a volt meter on the two outer prongs in plug then the two inner two of them will read the same when yoou move the level up and down and when you put meter on other two it will change when you move level or the level part of pump isnt working correctly. my old tahoe did that and when it would get to a 1/4 of a tank i knew it was almost out of gas.
A faulty temperature sending unit. It should be located on or near the thermostat housing. If any of your gauges reads zero, the check gauges light will come on. Sometimes even if the fuel gauge gets too low, it will trigger the light. It may be the connection at the sending unit. It may have become loose so wiggle it and make sure it is securely connected to the sending unit. If the temp. gauge needle pegs at the top of the gauge, it means the sending unit has grounded out and is faulty. If it jumps, reads off or not at all it could be a faulty sender or a bad connection.
Check the coolant level in the plastic bottle for coolant under the hood. If it's at the proper level and If your engine temp. gauge shows it's operating at normal temp. range, you can drive it. You need to bring it in to have the engine trouble codes 'read'. Most parts stores do this as as free service. They will plug a hand held scan tool into a port under the dash, and 'read' any stored codes that have caused the engine light to go on. They can tell you what the code #'s are and what to do to correct the problem. If you have any further questions, post them and the codes here.
I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck
The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.
