Another van out of limp mode – thanks to Complete Diagnostics.

We recently visited GG Automotive in Worcester to demo the Complete Diagnostics tool on a Tesco delivery van that was stuck in limp mode.

Shaun was on site, with Calum providing remote support. Together, they applied the correct settings and adaptations to the newly fitted EGR valve, resolving the issue and getting the van back on the road.

Fast, effective, and fully remote.
