I've seen vidoes online where folk have connected vagcom directly to clocks/a cluster that's removed from the car. Does anyone know what cable I would need for this? I'm going to attempt repairing the lcd so it would be very handy to be able to test the clocks out of the car before putting them back together.
This is the video: https://www.youtube.com/watch?v=64hRG4-jouc Looking through the comments it's not just an off the shelf cable. These are the instructions from the comments (think the guy is dutch? so translation is lost a little): If you have a cluster unit with a green and a blue connector at the rear of the unit, you need the blue connector. In that blue connector purple/red, red and red/purple go to +12V. From those 3 lines solder them together, and connect 2 lines. 1 of the 2 goes into the OBD connector, the other to the external power supply. Next line is gray/red, that lines goes into the OBD connector (K-line). You just need and extra OBD connector (partnumber eg 3A0 972 695 A ) @pin 16 +12V @pin 7 K-line or canbus @pin 4 and 5 connect to mass You need an external powersupply as well, And for your aid, special software which is capable of reading the eeprom, like VAGdash. Half understand what is being said. First bold part mean solder all three together and then take two connections off it? Not sure what the second bold part is......
i just did mine in the car saved me making up a rig but yes that would be handy if you get a second hand clocks you can load the file off the old clocks to the new ones saves changing the screen don't mater if you use petrol or diesel clocks as you can swap the foils just have to use the same type of clock ie immo 2 or 3 and the same make as you get two makes of them i used vag tacho and vag commander whats wrong with the screen faded ?
Yeah screen fades in and out - sometimes goes out completely. Was going to take it apart and chance just re-soldering the screen in the hope it's dry connections ('98 A3 1.8T) Liked the idea of being able to check it all out of the car. Would just save a bit of time putting it in and out if it needs "playing with" + it's pretty cool What you're saying about loading files across clocks is interesting - does this get round immobilizer issues as well? (Trouble would be trying to find clocks that dont have the same lcd issue!)
tends to be the full screen ones that fade mine can look a bit patchy sometimes in the heat or bright light though is fine in the winter and dark nights they have a light sensor next the speedo stop
I have a random CE2 fusebox which I hook up to an old PC power supply to give me 12v power, then I can plug various things into it for testing. with the mk4 clocks its just a case of chop out a couple plugs from a donor car and wire up the live, earth, ignition and diagnostics feeds to whatever you use to get 12v on the bench: http://www.clubgti.com/showthread.php?277595
