Hi guys, first post here! Recently our 5-5 reg Connect broke down on the motor way. After three weeks in the shop in the local garage and a fuel pump later they have told us that because it is a ex police van it had a solid mass flywheel and not a dual mass, and that because of this the error codes their diagnostic computer was giving were incorrect. Is it true that police vans are fitted with single mass instead of dual mass or are we being had because of a wrong diagnosis? Cheers, Ozliftoff
