Yeah right.....not just an hour and a half but AT LEAST an hour and a half to find the source of a leak on a car for which I am a skilled tech and work on these cars week in week out so I know exactly where to look - and with the benefit of a ramp. I'd have found it hard not to laugh at him. More like 5 minutes......£261 ker ching. I assume that the techs must be on some sort of bonus scheme to drive up revenues.he said it will probably take at least 90mins to find the leak at a cost of £261.
