Never, ever use this company they are complete Charlatans. I had a Evaporative emmisions control system failure for incorrect plurge flow. They charged charged me for replacing the emissions system but they had just added adhesive to to the side in an attempt to prevent air coming out and this has worked for some time. I took it into another garage today and was shown the fault.
When I asked to see the fault readings he told me that he can just disconnect parts to give false readings to show up what he had done.
NEVER, EVER, USE THEM!!!!!!!!
