There are definitely times when each will be best.I had similar problem with my 2004 freelander1, the cop gave me a chase because of black smoke from exhaust like hell. Went to a garage he didn't open the engine lid just plugged in the diagnostic tool and said it is the turbo charger combustion problem paid £20 for the test. See as he was fully booked I went to another garage he insisted he also use the test gear and found the same fault in combustion but can't pinpoint the part or area and gave an appointment to come back. He suggested go on the motorway and accelerate the smoke should clear up tried that too. That night I came back to landyzone website checked black smoke threads and someone said it's the hose. Opened the bonnet lid straight away and saw a large black patch inside bonnet over a bent hose with a 1" visible crack. Job was easy replacing the part. Worth opening the engine lid before plugging the computer anyway times were changed we trust diagnostic tools first before the naked eye.
