Hello, I have had my (Australian) MY10 Scout 4x4 Manual Diesel 2.0 for about 3 months now. I would love this car if it behaved well. I need help diagnosing an issue please. Symptoms started 10 days ago, I have driven it very little in this time. Sometimes when starting after idling for a few seconds the motor goes KUNK KUNK and stops. Engine runs a bit rough and has a vibration. Dash warning lights - Engine Light came on and stayed on for a few days and then went away. Glow Plug light was flashing at same time, but went away and stayed off after ignition turned off. Under heavy acceleration the exhaust blows a bit of black smoke. Car previously had DPF Delete and EGR blank plate and relevant tune, so I doubt it's DPF. I have taken it to 2 mechanics who want between $150 to $200 just to diagnose it, I want a clearer understanding what the problem could be before I start spending money. Previous owner personally (no mechanic) replaced glow plugs 12 months ago. Car doesn't leak or burn oil. I will try to get some scan data to add to this post. Any help or Jedi mind tricks appreciated.
