Need advice on a diesel glow plug tester
Anyone here tested the glow plug testers from ECUTools? Checking diesel glow plugs with a multimeter isn’t always accurate, especially on newer cars. I found a dedicated tester that checks each plug under load. Worth buying? Here’s the link I’m looking at: https://ecutools.eu/

Load testing is much better than just checking resistance with a multimeter. A plug can show normal resistance but still fail once it’s under real load, and this tester makes that obvious right away. Weak plugs heat slowly or not at all, and you can see the difference in seconds. It also helps catch issues with the control module or relay, not only the plugs themselves. If you work with diesels even a couple of times a week, having a proper glow plug tester saves a lot of time and guesswork.
