Where are you located? Do you mind buying from the US? Might find something from Clairparts.com or ECSTuning.com They can order just about anything. Also call Worldimpex.com

 

Usually that ignition module fails on cylinder number 2 but it does fail on others too. Check the plug for fuel. You may also have a plugged or otherwise non operating injector. As for the module, theyre usually stocked here in the us.
