Jake (Service Manager) able to diagnose my Mazda Bravo had a cracked motor head during course of a phone conversation. Confirmed later, and only took 3 days from visit to point of collection for replacement and repairs, including ordering parts. Previous service advice (near where I live) was wrong, twice - despite inspections. Cost a new starter-motor and glow plugs, all unnecessary.
Coffs HD also located another separate issue needing repair.
Absolutely outstanding mechanics at Coffs Harbour Diesel and all very helpful.
