Well the work is done, i collected the injectors from swadlicote diesel yesterday and fitted them the same day. I recoded the injectors and she started and ran fine but when i checked the injector codes the formidable showed that two hadn't held their codes. To cut a long story short i left it to cool overnight and did it again this morning, it seems that the super F can only code one injector at a time but i got there in the end and now its such a different car. I would like to say thanks to swadlicote diesel as the guys were really helpful and polite, they even let me jump the counter to go for a wazz in ther toilet as it had been a long journey .
