Viperry

i have a 2000 180 with around 89000

my car overheats when off the fans never come on when its off and the do come on when the car is running but the shut off imeditly, i dont know what else to do ive tried alot i cant find relays and the worst part is i think that the overheating is killing my coil packs cause i have to replace at least one a week so im like freakin out. Where is the relay box on our cars is it located in the engine bay cause i know its not in the fuse box


thanks

Take it to an independent repair shop.

How about this:

2001 Audi TT Quattro Roadster L4-1.8L Turbo (AMU) Vehicles With High Pressure Sensor - G65 - Vehicles With High Pressure Sensor - G65 - Coolant Fan Control (FC) Module
-J293- (Vehicles With High Pressure Sensor -G65-), Electrical Testing Terminal assignments at -J293- (vehicles with -G65-) Location: In engine compartment on left long
member Function: * Activates coolant fan (s) -V7 (speeds 1 and 2) * Activates A/C clutch -N25 * Processes the square-wave signal from high pressure sensor -G65- and
sends a positive signal to -E87- to indicate the refrigerant system pressure is OK. * Switches on after-run coolant pump -V51 (if equipped) for continued coolant circulation
when the ignition is switched on. The pump continues to operate for a short time after the ignition has been switched off. NOTE: * The following -J293- connector A
terminals are vacant: * Terminal 1 (on vehicles without after-run coolant pump -V51-) * Terminals 3, 5, 11 and 14 * -J293- connector A,, terminal 13 is intended for
disengaging -A/C clutch -N25- when the instrument cluster sends "excessive coolant temperature" signal. As disengagement of - N25- also takes place via the A/C control
head - E87-, -J293- terminal 13 may be vacant on some vehicles, dependant of vehicle wiring configuration. * The function of Coolant Fan Control (FC) Module -J293 and
vehicle wiring layout will vary depending on whether vehicle is equipped with A/C pressure switch -F129 or high pressure sensor -G65-. * Various versions of Coolant Fan
Control (FC) Module -J293-, used in conjunction with high pressure sensor -G65- may be installed. At the time of publishing however, All TT equipped with -J293- / -G65-
have version where coolant fan(s) -V7- speed 1 is always switched on automatically whenever the A/C clutch -N25- is energized (regardless of refrigerant system
pressure).Terminal assignments and switching conditions (high pressure sensor -G65-) Terminal -1- Ground (GND) Terminal -2- Signal output (square-wave signal to -J293-
and ECM ) Terminal -3- Positive (terminal 15) NOTE: * When electrical connector at -B- is disconnected, the A/C clutch -N25- cannot be activated. * High pressure sensor -A-
transmits a square-wave signal at a pulse rate that varies according to the refrigerant system pressure.Switching conditions - Coolant Fan Control (FC) Thermoswitch -F18/-
F54 * -F54- between terminals 1 and 2: Closes at approx. 95 ?C (-V7- switched to speed 1). * -F18- between terminals 3 and 2: Closes at approx. 102 ?C (-V7- switched to
speed 2).

controls fan ops is gone.

Try this: turn on the car and put the AC in-service, on MAX. If the auxiliary fan comes on, you need the new relay/controller. If not, you have a more interesting problem. Tell your tech/stealer. It can be fixed relatively inexpensively.
