andy35554 0 Posted June 6, 2005 hi, i have a similar problem, intermittantly the light will stay on, usually it flickers a few times and then goes out (is this normal?) . I have tried all connections including a big multiblock in the engine under the expansion tank, sometimes this has resoved the problem, poor electrical coonection. I have 4.9v at the sensor, is this right? What is the data lead you can use for the engine, do you need special software and where does it plug in? thanks in advance Quote Share this post Link to post Share on other sites
