Mercutio 0 Report post Posted November 26, 2008 Hi, I've recently brought a 1989 302i Touring, which I'm enjoying. I was hoping someone could tell me which version of Motronic is fitted to this model. Also... I understand this model has a M20 powerplant, is the 2 litre a smaller bore or stroke? Thanks in advance.

If it does, its 1.3, if not, its 1.1. Or just find out the number on the ECU and google it. Or unplug the ECU and see how many rows of connectors the plug is, if its 3 rows it is Motronic 1.3. I'd assume it's 1.1 though. Quote Share this post Link to post Share on other sites
