“ECU 2012 Mercedes GL450
So Garage was stating that the ECU was faulty and it would be approx $4K to replace, which on a 11 year old SUV would be the end of it. I spoke to 2 ECU repair shops with ECU Pro giving me confidence they would diagnose and then repair or replace after copying all info. They did exactly that and it worked first time and SUV is back on the road. Great result and quick to fix”
