[matty657]

started the car today 1.8 VRS:D and got a plume of blue smoke at tickover :eek:, drove it to work :cool:and it cleared up no smoke, car drove with no power loss or strange noise's, has not happened again after alot of stoping and restarting, but got a fault code P7705 turbo/throttle valve connection pressure loss P1297. HAVE RED OTHER POSTS ABOUT THIS FAULT :mad:BUT NUN MENTION EXCESSIVE BLUE SMOKE WITH THIS FAULT, ALL TALK ABOUT INTERMITANT POWER LOSS WHICH MINE HASENT, any info would be grateful, thanks.

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 .
