Aquinas 0 Report post Posted April 15 Hello all I've got a 525tds Touring that has a parasitic drain on fuse 20. Any ideas what it might be or tips on how, having isolated it to this fuse, I go about finding the culprit? Many thanks Aidan Share this post Link to post Share on other sites

gilescooperuk 3 Report post Posted May 1 Go for the most obvious one first, Park,tail, Underhood lights. Probably a drain from a short, more likely the underhood light (when was the last time it was used or checked...) i had a similar problem on my kit car, put the car in a dark garage, and found the rear lights were glowing dimly with the circuit off. Couldn’t see this in daylight or in the garage with the lights on. start pulling things until the drain stops and then work out what is wrong. Share this post Link to post Share on other sites
