Several thousand miles after buying an almost new VW Polo it developed an intermittant fault. During or after rain it had difficulty starting and when it did occasionally stalled at roundabouts and junctions. Took it to the VW dealer who originally sold it, £250 to put right and the problem returned within a fortnight. Took it back to the garage not expecting to pay as the problem wasn't solved; they'd carried out further work and wouldn't release the car until another £200 was paid. Since then the problem has never reoccurred. After exchanges of letters am taking the garage to court - their (detailed) defence is that the 2 faults were separate - my non-expert response is that whatever they did first time didn't resolve the fault otherwise it wouldn't have reoccured within a fortnight. Has anyone had similar experience or can offer advice? Thanks
