Jim Bowen 1 Posted October 17, 2012 Last time i had some welding done i disconnected the ECU and the ABS ECU. Found a little hole that needs doing on the rear arch Is it really needed to remove the ECU's, its just i've covered them all back up again now :( Quote Share this post Link to post Share on other sites
floppyman 0 Posted October 17, 2012 Dont need to remove... Just disconnect the battery. And if its a mig welder you dont need to disconnect. But....... I allways do since my g60 got on fire after welding the exhaust with a spot welder Quote Share this post Link to post Share on other sites
Human Joist 10 Posted October 17, 2012 Someone is bound to say otherwise but I just disconnect the battery and leave for a few minutes then carry on. Did this on my last few VW projects and had no issues at all. Saying that my ABS light likes to light up half the time and has done since before the welding.

craigowl 0 Posted October 18, 2012 My ECU failed a few weeks ago. I wasn't even looking at it! "Old electronic component" I was told, liable to die. A nuisance if you have to source another. Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted October 18, 2012 My brothers ECU died recently as well, weird how things just fail like that. Thinking i will disconnect it anyway, some places say leave the battery connected as it prevents "spikes" in the system which can damage components Quote Share this post Link to post Share on other sites
