2003 Audi A4 Cabriolet ...cooling fans come on at start up

I have a 2003 Audi A4 Cabriolet 1.8L, turbo DOHC, 39k miles. I've been having a problem with the cooling fans and the check engine light coming on. Upon start up, (cold engine), the fans come on immediately.
I took my car to a local garage and he told me that the thermostat assy. needed to be replaced. After having the work done, I still have the same problem. Is there a cooling fan sender on this engine ? Any help would be appreciated.

    Thanks for your reply. I've had this car for about a year and this is the first problem I've had with it. Can you tell me where the cooling fan sending unit is located?

    I have the same problem. It only happens when the car is cold.

Yes this car should have a temperature sending unit that tells the fans to kick on. If it has two fans one of them is for you Air-condiontion, and it will turn on whenever the ac is being ran. One other possibility is if you bought the audi used the owner before you may have hard wired the fan to run whenever the car ignition is turned on. The only reason someone would do that is if they were to lazy to fix it properly.

Where is the thremo relay switch located on a 2003 3.0 audi A4. my problem is the radiator fans won't shut off and have been told this may be the problem


Sounds like your on the right track. The thermal switch closes when the temp reaches a certain temp and this allows power to the fans to draw more cool air into the engine bay. I would start there or you may have a short on that circuit also allowing the power to go to the fans continuously.

Hi i have 02 audi a4 slimline. on motorway going 70 mph and to past a car dropped it down to fourth gear probly hit 90mph. Drove for a further hour and a half, and hear a bang under car. car started to loose power. was drivable but hissing noise come out of it when accelerating. Feels like turbo not kicking in. Would this be that the turbo has blown of maybe burst pipe or something. If anyone can share a light on this i would be very greatful. Cheers

Turbo= not working


Most likely the turbo is gone. What ever part of the turbo went, just replace the entire turbo. Not serviceable 99% of the time. The engine will not like being driven for any extended period of time with a bad turbo.
