SOURCE: have 2004 audi 2.0 fsi main fan keeps coming on when moving.

because of the shape of the car and temperature within the under bonnet,audi/ vw use the electric fan to maintain a closer tolerance of engine temperature.for maximum economy.so your main fan will come on more often than perhaps an older car that you may have owned.as changing the thermostat has shown no change.

You're going to need to visually inspect for leaks and if no external leaks are evident I suspect your head gaskets are leaking again - check oil for coolant in oil - it will look milky

SOURCE: Audi A3 2.0 fsi 2004 will not start

Sounds like you have a weak battery. It doesn't take much power to make all the lights work but you need a lot of current to start the engine. You can test the battery by looking at voltage across the terminals when you try to start the car, if it's less than 12 volts your battery needs to be replaced. If your battery is more than 5 years old it should be replaced anyway. Good luck, let us know how it goes.

My Audi A3 2.0 fsi sline Quattro is struggling to find gears ( very stiff to change and impossible to find reverse with the engine running)


First check the fluid level and make sure it is correct. If it's good you will then need to go to the dealership to have the codes pulled. I hope the problem is the fluid because it will be expensive otherwise.

The epc light comes on the odd time, in my 2004 audi a3. I cannot find the manual. I am interested in knowing what it means?


I am having the same problem on my Audi A4 2004 FSI, lose power whilst driving at speed with the EPC light coming on. Looks like a design fault of some kind with Audi petrol engins, have read a few forums about this but no clear straight answer. Check the link below:

Does it keep running till the batt is flat? It could be the aircon condenser fan running - on the left as you stand in front of the car. This is a common prob with A3s of this age.
I have a '05 3.2L Quattro V6 and suffered the same prob. The batt is in the boot of the V6 and is sealed like Fort Knox so impossible to disconnect. After about 3 days with this the fan running constantly and having to put a charger on it every night I let the batt run completely flat to try and reset the complete system - no DIS lights - no starter motor clicks - DEAD. Then I jump started it and the prob disappeared completely. Everything is working perfectly ncluding the aircon. That was 4 days ago and 'touch wood' I've had no probs since. I know this won't work for everyone but it's worth a try before forking out £300+ for a new condenser fan unit. Good luck!
