2003 Audi A4 Cooling Fan Relay Location
I'1000 really starting to enjoy my new-to-me 2004 Audi A4 Avant. Like whatsoever Euro, it's got a few quirks but overall it'south been an honest, fun to drive sports wagon. Even so, the other day my Audi had its first real "problem." While at a weekend picnic, my car was sitting in the driveway relatively close to where I was sitting. With music and conversation, it was hard to hear annihilation other than the ambience sound of the picnic. All of a sudden, a friend turned to me and asked me if I had left my auto on. I told him "no, why"? He so told me that it sounded like it was on and after listening very attentively for a second, I could hear what sounded like an idling engine coming from the driveway. As I got closer to my machine, I could hear the auxiliary fan spinning at full speed! Amateur Diagnosis The car had been sitting for over an hour and the keys were in my pocket. Surely something wasn't right as my car sounded similar an airplane on take off. I turned the ignition to the 2nd position and immediately the fan close off. I pulled the key out and walked away a bit confused, trying to convince myself that perchance what happened was normal when information technology was hot. Embarrassed, I told my friend the car had some cool feature that I accidentally turned on where the fan runs every at present and once again to pre-cool the cabin knowing damn well at that place was no such affair on my machine. I as well wanted to hear if it would happen again so I listened very closely for information technology. Certain enough, nearly 45 min subsequently the fan came back on and required the ignition to exist switched on to turn it off. Afterwards doing some research, it seemed every bit though this was a problem that had affected a decent number of B6 owners. The root of the problem involves chock-full drains and/or a cracked ECU box. A few weeks dorsum, I had to drive the motorcar dwelling house in a torrential downpour, and then if water was going to go anywhere it shouldn't have, that was the time! Corroded Relay Essentially, what can happen is water can get into your ECU box and crusade a pocket-size pool to course in the bottom which, in some cases, can submerge relay 219 (which operates the fan). If this happens, the internals and contacts of the relay can become corroded and crusade the fan to act erratically. If this has happened to you, you will need to replace this relay and either articulate your drains so that water will no longer pool OR replace your cracked, broken ECU lid. What Y'all'll Need Accessing the relay is fairly straightforward. Begin past removing the weather strip and then the plastic cover that goes over the battery, ECU box and motel air filter housing. Your ECU box is located on the correct manus side of the engine bay. Remove the three T30 Torx screws in the forepart of the box. My ECU lid was missing the left right spiral and it seems equally though a lazy mechanic had only broken information technology off at the dorsum right ane due to the need to pull the wipers off to access that screw. Therefore, later on removing these three screws I could pull mine out. The proper style to access these final 2 screws is to remove the right wiper, allowing you to motility the plastic shield enough to admission this rear screw. Replace the ECU cover if it is compromised in whatsoever way. On some models, similar mine, there is a metal clip which bridges across the ECU itself. Button down on either finish of it to release the prune. You can and so elevator the ECU out of the manner which will reveal the 219 fan control relay. Note the show of water in the ECU box from the settled orangish "rust dust". It seems as though the other two relays have been unaffected by the presence of water in the box...or at least to my knowledge. Information technology may take some patience trying to wiggle the relay out (the corrosion doesn't help). In one case you remove the former 1, ensure that the internal contexts aren't compromised. Pop the new relay in and re-install the ECU and cover (properly!). Besides, use this feel every bit a friendly reminder to cheque all of your drains to ensure they are make clean and functioning properly. At present yous tin can relax knowing your fans are no longer haunted! Have you experienced unusual behavior from your automobile? Let us know in the comments.
