Had this for a wee while now, When I start the engine I get the smell of diesel fumes in to the cabin. If i open the bonnet, towards the cab I can smell it really strongly with the engine running, Is this normal? I've checked the exhaust and can't see of hear any holes, its recently had a new egr, the swirl flaps rod is still connected but theres a lot of soot and oil around the passenger side most one so I'll need to look at getting that done at some point i guess
