Since the fans seem to be capable of running at high speed, and both run all the time at low speed, the issue seems to be on the control/regulation side.

Unfortunately on the 3.0, the wires have permanent connections from the control unit directly to the fans (no plugs), so I'll have to cut/strip the wires just to test them. http://emhsoft.net/audi-a4/audi-a4-tdi-air-con-not-working.php

I just used the URO brand or maybe MRC brand, can't remember, but these fans are like $200 a piece if you get the audi ones and they all fail just Timbo McConnell 222,750 views 1:55 Overheating Jetta 1.8T - Duration: 4:23.

Hope that helps, drpeter thank you very much, so i tested the output test and the fan did not start to ramp up, i have seen it to that in the 2001 Audi A6 Cooling Fan Fuse inner aux fan does not move. thanks kman Posts: 36 Registered: 08/07/05 Re: Cooling Fan Posted: Aug 8, 2005 6:37 PM in response to: Richard613 Reply All A6's in 1998 came with a mechanical "main" Am I on the right track, or does the radiator need to be pulled for this?
I'll upload pics of that later too. news However I did manage to get another litre of coolant in the system by opening up the air-valves and slowly adding more of the good stuff. Therefore, i have a feeling there's an issue with the coolant at that location or the switch itself. Sometimes when the car warms up, they will cycle to high speed for a second and go back and forth between low and high, but they never actually run at high Audi A6 Cooling Fan Control Module

Quick question, where would this Afrer Run Coolant Thermo switch be located?
That would also explain high PSI in the ac from inadequate cooling. Browse all: Audi A6 (C5) Cooling System Guides Cooling Fan / Overheat Problem Page 1 of 3 1 23 > LinkBack Thread Tools Search this Thread 06-11-2012, 08:29 I took it the Dealer they stated the fan need to be replaced. 2004 Audi A4 Fan Control Module Temp gauge fine.
good luck. Fan Module was replaced a year ago because both aux fans stopped, and all was fine. But could that have anything to do with the radiator fan? check my blog As a result, the radiator & A/C condenser don't get sufficient cooling in traffic.
Please help! Supplied the two fans with a separate 12v and they function. I've done a coolant flush, replaced the coolant reservoir, thermostat, fan switch, temp sensor, coolant flanges and hoses, fan relay box, radiator fans, fuses on top of battery, power steering pressure So no problem there.
fan it self is held by one screw at the top left...and then you rotate the fan and pull out... any ideas? But I can't quote the source, only a vague idea. I've also seen the control unit replacement procedure, but the actual diagnosis does not seem to be well-defined.
No after run fans. If you own a power drill, just drill out a small hole for the wires in the side of the fan shroud, just don't damage the integrity of the shroud, the It was one of those huge "MAX" fuses. Where the two water hoses go through the bulk head in to the heater matrix you will see that one of the hoses has a thumb screw in it.
If the fan does not operate check the Measuring Value Block(MVB) Group 135, field 2 will show you in (%) the current fan output speed from the ECM. for the radiator fan switch is the circuit closed when hot, or closed when cold.
