MZpog 10 Posted December 11, 2015 Been looking at new HT leads as I fancy a bit of colour rather than black. Noticed that the 1.8 and 2.0 leads are listed separately, the 2.0 costing more. I've never owned a 1.8 but presumed it'd be the same layout as the 2.0 and that they'd use the same leads. So what's the difference? Quote Share this post Link to post Share on other sites

MZpog 10 Posted December 11, 2015 there's a sensor on the coil lead for the 2L ecu I'm sure mine doesn't have one - is it necessary? Where does it plug in? Quote Share this post Link to post Share on other sites
Jim 1 Posted December 11, 2015 You should have it, though I've never fully understood the impact / usage as the car will run seemingly fine without it connected. Apparently it helps detect knock / pinking. It should be on the ignition lead for cylinder 4 and connects to a plug, which runs off into the ECU I think. It's not exactly like this one, but similar... http://www.volkspares.co.uk/Shop/images/030905377-knock-sensor.jpg Quote Share this post Link to post Share on other sites

I'll have to have a look for a spare plug. Quote Share this post Link to post Share on other sites
