As Guzziman suggests, the 0.666 and 1.3 engines differ. I got my last new one on eBay (Copen Ignition Coil for sale | eBay). Also as Guzziman suggests knowing how many and which ones have failed will help. My OBD2 reader helped me here.
Thanks for the replies. It's an 04 plate so 660 engine (90k miles) No readings when plugged in so trying coils first. Tried used and improved symptoms slightly but really need new.
