SAAB 9-3 Petrol Fuel Filter ' SAAB 9-3 Fuel Filter Change - YouTube

It appears to be a known issue.
Blue smoke is oil.
White smoke is water.
Black smoke is rich mixture.

Blue smoke is probably from the turbo bearings.

Try looking under the bonnet

The central lock system won't exactly lock the fuel "cap" but it does have an actuator that extends to prevent the fuel door from opening when the doors are locked. Easy to test, as long as that's working then you're lucky enough to not have to bother with a locking gas cap & more keys!

1. Try locking and unlocking of the doors five times with the remote to reset the immobilizer.

2. Key in ON position push Open button on key fob.

ouch a saab,, why a saab?
sorry, is not saab like yugo cars? and volvos'?
common places.
glove box.
left lower side of drivers seat (LHD cars) right side RHD cars.
un center console (open lids look)
under dash.
buttons on dash.
just look all those places and bingo.

May sound a little stupid im just trying to cover all bases but have you made sure the car is unlocked. If the car is locked then the fuel door will be locked.

I think you should try this website link that I have attached. It helps you repair your vehicle easily without more help. Ask the girl in chat at the bottom of the page

Does the key still pop the trunk/hatch? That would also indicate whether or not it was the key remote. If that function works it's probably nothing on the car (i.e. "receiver") end.

There is a very good SAAB forum that would likely be the best place to find out if somebody has has this issue before and what they have done: www.saabcentral.com

On 1999 9-3 models there is a fuel filter located under the pass rear door. However if this was plugged it would not kick back in after a short time. Typical suspects are crankshaft position sensor which will work well on a cold engine and intermittently cut off and on when the engine is hot. Its a cheap sensor, and very easy to change. Possibly check condition of spark plugs and the DI cassette as well. Also check function of Fuel pressure regulator. Any fault codes stored (CEL on?)
