My sis-in-law has a prob with her Zafira, she says the whole car shakes and shudders at 50 mph, but it is an intermittant fault, and the dealer 'supposedly' can't find anything when with it.
Vauxhall have replaced the fuel filter, but it hasn't cleared the fault, and she's also been told that they have 'reset' the electrics, which sounds a load of bollox
It's a 2.0L diesel, 2008 model
Anyone have any ideas if this is a known fault? Or what the likely case might be? Or just any suggestions generally?
