Hi everyone thanks in advance for any help.sorry for the silly question but the title says Can i use a 2004.5 + auto ecu and modules to run the same year model S40 ,C30 or v50 without getting the ecu reprogrammed for the manual box straight away would it run say to get me ours trouble and to a Volvo specialist to have itvreflashed, I'm assuming they're both Bosch me9 ecus and possible that the pinouts for the plug would be the same. I'm having immobiliser issues due to faulty modules and I'm looking for a cheaper fix than going to the Volvo money pit dealer as. It's seeming to be quiet hard to find the ecu kit for a T5 m66 car. I'm asking this because I'm finding it near impossible to get a ecu start up kit for a S40 an every time a C30 pops up wrecking i either miss it or the wreckers don't bloody answer. Apart from this what stand alone aftermarket ecu would be best suited for the job this is last resort but seems like it might be on the cards.
