Inspection – VOLVO VCC or free workshop

Hello together, after having done the work on my V70 D5 (185) MY 2006 in a free workshop. Was on Saturday the discussion… A friend of mine, who had once made an apprenticeship as a car mechanic, was of the opinion “With a 6 year old car you have to go to the contract workshop”. Reasons: + Fachwissen und Ausstattung (Computer & Co.) – hourly set spare parts prices We then came to no result… Unfortunately in the workshop had forgotten the After 5 min in the forum and 2 min in the car was the MENDING WAY… Is now the FREE WORKING an ALTERNATIVE or have I made a mistake ??? Thanks. frogy1967
