Saab 9-3 Aero Problems
Read below where Experts have answered questions regarding Saab 9-3 Aero issues.
The “Low Oil Pressure, Turn Off Car” light comes on intermittently on a Saab 9-3 Aero until the engine is fully warm. What is wrong?Case Details: loss of power and the smell of hot coolant is often noticeable when the engine is turned off. All fluid levels are fine.
The symptoms described are typical of a failing turbocharger. This usually happens with the intercooler or the oiling system within the turbo. The unit will have to be either overhauled or replaced. It would be worthwhile to have the turbo checked professionally and if it is only the intercooler that is faulty, the repair costs may make it a better option than replacement.
A 2009 Saab 9-3Aero keeps losing coolant. All hoses, the radiator etc. have been checked and there is no leakage. Why is this happening?This is a one of the more common of Saab 9-3 Aero problems. Have the water pump checked for leakage or signs of residue from the weep hole. An improperly torqued cylinder head gasket can also cause this kind of coolant loss. If neither of these are the cause, then the cooling system will need to be checked for CO/ HC presence. This will indicate that the engine block is porous and coolant is being burnt off during combustion. This has been an ongoing problem with these vehicles.
A 2004 Saab 9-3 with a 4 cylinder engine and a 6 speed manual gearbox begins to buck and jerk when the turbo gauge goes into the orange / red zone –what could cause this?The bucking and jerking when the turbo gauge goes in to the orange / red zone is caused by the over-boost protection system that cuts in when the engine revs are near the rev limiter. It seems that the vehicle is being revved too much in low gears and reducing this will stop the jerking from happening.
How can a cell phone be hooked up to the car phone on the steering wheel of a Saab 9-3 Aero?The first thing to be done is that the cell provider must be contacted to check if the phone is compatible with the Saab system. If it is compatible, the car should be taken to a Saab dealer for installation of the specific hardware for the vehicle model year to activate the hands free system. The ICM will also need to be reprogrammed to recognize the cell service being used. . In case there is a problem in this procedure, Motorola makes a very good Bluetooth kit that will work with any vehicle. The cost is around $200.
At high revs, on a warm engine, the “oil Pressure Low” light comes on in a Saab 9-3 Aero. Could it be an oil pressure sensor issue?Case Details: The warmer the engine, the higher the revs have to be to trigger the warning. Oil level is fine and the car is running well. Mobil Synthetic 10-40W oil is being used.
The oil being used is the correct one for this vehicle. It is unlikely that the problem is caused by the oil pressure sensor. They are normally very reliable and if one is defective, the problem would typically be at one pressure reading, not all across the board. The best thing to do will be to use a manual pressure gauge to check if the pressure is really dropping. If so, a detailed check will need to be done. If the pressure is steady, then the problem will be with the pressure gauge.
Saab 9-3 Aero owners often have problems in locating help and information sources to provide the inputs they need to keep their vehicle in good running condition.
