You have a check or MIL lamp onThat is not anything new,they havebeen on all vehicles for over 30 yearsOnce you retrieve the code,you will know thesystem with the fault,then Google the code& read up on the problem & solution

Very likely a bad ignition coil bit could be as simple as a foouled spark plug. Try to get access to a VAG-COM diagnostic tool, or take it to a shop that can check the fault codes and figure out which cylinder is misfiring.

Check the engine speed sensor

first check fuses...if that dont work you possibly have faulty wiring to the switch or switch burned out...

It sounds a lot like either the bulb went out or the fuse is blown. If there isn't anything else out it's likely the bulb, otherwise, check your fuse panel.

check the plug going into the light it could need to be pushed in

just pop a new glass on ,simple

Hi there:the Audi manual never talks about a 2 stage aux fan just that the aux fan runs with ac on and it can run with out ac on if there is an overheat issue on the coolant side where as the a4 info clearly states a 2 stage aux fan system that would lead me to think the early 4.2 did not use a 2 stage system. Your car is not overheating and boiling over out of the coolant tank it is showing a little hotter than what would be perfect but it is still in what Audi calls acceptable range. The whole coolant system is new I would start looking at your sensor and gage systems there is a coolant sensor in the rad but that is most likely new if they replaced the rad. The gage uses a temp sensor on the engine for the gage I would replace that sensor and test the gage with a resistance input tool we have at the dealer. Could be a gouge or the wiring to it. There is a coolant fan module that could be defective if your sure there was a two speeds to the aux fan.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

Hello! If you have an owners manual the symbols are described in it...If not, visit a dealer...They have a card with all symbols defined...I would need a better description to identify the one you are asking about..Is there a circle or an X involved?

You have air trapped in system , change thermostat , bleed air from system , let it run hot while adding coolant with blower full blast on all front and rear heaters .
