I got a lift down the garage and spoke to the service manager who said he thought the fault could be related to the fact the oil was still clear and there was oil in the sump, his explanation was someone (me) had had an oil leak, then run the car without oil, then got the leak repired and topped up the oil. I told him that not only would i not have done that, but it seemed very illogical to do so as the car was under warranty and i would have payed to repair the leak instead of getting renault to do it for free. Seeing as he was accusing me of tampering with the car i asked to speak to the dealer principle who upon hearing it was an import suggested the importers probably did it. he also went into a long winded speech about how importers offer no service and they get crap cars and the renault dealers have to sort them out. I responded by telling him that they come from the same factory so are all Renaults crap? and the dealers make more money off serviceing then sales so why would he complain? he agreed, but still said he thought the importers may have tampered with the car. I then asked about a courtesey car and he said they were all out, I asked for a rental car then as they promise to provide one on the renault website he said he wasnt obligated to do so, I asked if he had a 2nd hand car he could loan me and he refused saying he didnt see why he should. After this i called renault who said they would try and get a car. 3 days later still with no car and after many calls to renault i spoke to the manager of Tins where i purchased the car, he managed to get me a demo from another Pendragon garage within the day and arrange insurance cover. I didnt tell Renault i had got a car through other means and they continued to "try" for the further 2 weeks my car was away, but never succeded. Finally i got my car back with a new engine in it (no further mention of tampering with the oil) and rang Renault again, they had agreed to pay the taxi fares i incurred over the time without my car, they were to say the least a little taken aback at the claim for £600+ worth backed up by reciepts, but they did pay, and so far the car has been ok. Anyway the point of that long winded rant was that I had a major Fault AND Renault managed to make it worse. But the dodgy importer provided far better custumer service then Renault or their garage.
