i have since repaired this fault as it happened again,i beleave the problem was the exhaust air recycle pump located just below the oil filter, the electric motor was semi seized and soaked with engine oil, the outter casing was also split possible caused buy the previous chimp who replaced the oil filter. i believe this pump recycles spent fumes upon startup untill the cat reaches running temperature then shuts off after a couple of minutes. hence this being an intermittant fault, owned the car for a month now and very happy with it .
