I brought my 2005 Land Rover LR3 here after the check engine light came on during a road trip that brought me through Boise. Obviously, this could've meant anything was possible and I needed to get it diagnosed as soon as possible, before continuing across the country. I brought it to AER and they were able to immediately have someone scan the codes and diagnose the root cause as a secondary O2 sensor. Rather than immediately replacing this part, they spent time tracking the wiring to make sure it wasn't another issue triggering the code. After some time diagnosing further, they explained in detail what was happening and we were able to get me on the road within an hour. All employees were very nice and professional.
