(coned im sure) now they fixed the starting problem but it runs realy rough oh and now central locking works! taking it home that night a 4 mile trip i got out to smell a burning smell the cat was red hot,so in the morning i took it to the mot garage thinking its a faulty cat, 5 weeks on the chap has said a throttle body needed cleaning as to much unburnt fuel and immissions were sky high!hes done this and guess what still the same im realy fed up and getting the van back today anyone think or put me in the right direction or want a cheap caravelle!! by the way its a 2.5 automatic petrol n reg caravelle pleassssssssssssssse help ,joke apart will be selling if anyone interestead fed up!!!
