VR6Pete 1,455 Posted October 8, 2004 Report Share Posted October 8, 2004 It continues!Ok, here's a little more info for you. at 94.5 degrees the air con switches on. at 91.5 degrees the air con switches off! along with my radiator fans. What happens to various components in the car at them temperatures?RegardsPete[ Edited ] Link to post Share on other sites
tandino 1 Posted October 8, 2004 Report Share Posted October 8, 2004 Pete - im assuming thats your oil temperature??Easiest thing to do is to run the system whilst bridging various components thus removing them from the equation...Sounds like something is possibly earthing through the rad cooling fan system at a guess ?! ?! ........Pete.

VR6Pete 1,455 Posted October 8, 2004 Author Report Share Posted October 8, 2004 id imagine engine temperatue, thats what the VAG com told me anyway. ive bridged the pressure switch, ive replaced the fan control module unit. ive replaced all 3 sensors on my thermostat housing. Im about to replace my rad thermo switch tomorrow once my hose comes. there isnt much more it can be really. i dont appear to getting the various speeds on my radiator fan so it could be the fan switch. We will see.Had it gassed up twice now by 2 different companies to see if it was incorrectly gassed. it's very odd to say the least! all the voltage comin from various components are reading fine! btw, I have climatronic!

tandino 1 Posted October 8, 2004 Report Share Posted October 8, 2004 Not really researched the VR a/c system in great detail yet but try bridging the a/c overheat cut out switch and the cooling fan switch and see what happens..Defo on the right track if its cutting yuor cooling fans at the same time....Pete.

VR6Pete 1,455 Posted October 9, 2004 Author Report Share Posted October 9, 2004 well, it's now fixed and what a pisser it is.Iv'e spent the best part of 200 quid on fan control module unit, sensors. regassing it and diagnostics.the red herrin in all of this is that it started to work at 94.5 degrees.today i replaced the radiator thermo switch just to rule that out (another 28 quid!) and in doing that I had to move the battery out of the way. what did i find? A broken terminal! another 30p later I connected it up and it all sprung back into life! I didnt know that the air con or what ever had more than 1 power feed! obvously it was getting power when the 2nd radiator fan speed kicked in or somet. A valuable lesson to be learnt then. no matter what diagnostic software is used, it wont diagnose a broken terminal!Ahh well, thanks to everyone who's helped me. and thank to Vince @ stealth for helping me out also.Pete Link to post Share on other sites

VR6Pete 1,455 Posted October 10, 2004 Author Report Share Posted October 10, 2004 me tooo - shame it cost so much for such a small fix! Link to post Share on other sites
tommy 0 Posted October 10, 2004 Report Share Posted October 10, 2004 think of it this way..................the next person who has the same problem can sort it for a fraction of the cost ......................like everyone said ...... glad you've got it sorted Link to post Share on other sites
