hi, thanks for the response. funnily, I live in Belium too. I bought the car insisting on a 'VAB-keuring', which also came up with the leaking hose the so called 'retourleidingen injectors'. they have been replaced by the garage prior to the sale. I have not tested the condition of the hose, but I will and contact the garage when not done properly. regards, ruud fvbourgonopsamail.com (fvbourgo) wrote in message news:<3a6dffb9.0312010056.2462e9c3nopsaming.google.com>... > > starting may take > > several (5-10) seconds in the morning, but eventually it runs ok > > Hi Ruud > > I have a similar Saab (same engine, same year) and I believe the 5 to > 10 seconds of starting is related to a leak in the hose which makes > excess diesel run back to the tank.
