Thanks!Pull fuse number 16 under the bonnet for app. 15 sec. re-insert the fuse. Start the car and let it idle till the SOC is full.
I gave them another call to see what things they've done. They told me they had disconnected the small 12V battery while installing the new battery, but I didn't tell them about the fuse (in case of miscommunication)
Hope this fuse pull clears the IMA and CEL and all is good! Keep you guys posted!
