I Newbie here. Owner of SMax 2.o diesel 07 plate Couple of months ago had problems with air in the fuel system - car turns over but does not start. After a couple of breakdown trips to the garage it spent 2 weeks while the dealer tried various things (drain fuel tank etc). In the end they admitted that they had no idea what the problem was, charged me for some parts but not labour and I took it home. Apart from the first evening it has worked well since until this weekend when it has failed again. One breakdown guy said is was a known problem, but can't find any reference on this site or others. You can see an air buuble in the pipe coming out of the filter. Repeatdly turning the ignition off and on has worked in the past, but not this time. Any ideas.
