[QUOTE="GWL, post: 161624, member: 4013"] Yes, we have to remind ourselves that it was a TV show, with limited time to show the complete situation. The later C5's are notorious for cold solder joints in the EBCM and the relay is simply used to turn power on/off. If the relay contacts are confirmed with a ohmmeter to have a resistance higher than expected, it's simple to replace at that point...or for peace of mind! In most instances, just desoldering/resoldering the 5 relay pins fixes the problem. In my instance, the issues would appear after a long run and heat soak which indicated to me the cold solder intermittent points (No Comm). I was fortunate that fixed my issues. In another instance it may take a electronics technician to find an intermittent part elsewhere...but at what cost. May be cheaper to buy a reconditioned module...?? The US Forum has a tremendous documentation on the subject with detailed instructions on how to do the repair yourself. [/QUOTE]
