When Mobile Is Ideal—And When It’s Not
Ideal: No‑start from batteries/cables, air leaks, clogged filters, lighting faults, minor boost leaks, alternator failures.
Not Ideal: Deep injector work, head gasket failures, major turbo or DPF replacement. In those cases, the tech will stabilize, document, and schedule a bay repair.
