A common issue you might encounter with the BMW E46 318i is the automatic transmission not shifting smoothly or staying in one gear. This could trigger the "safe mode," also known as "limp mode," where the transmission locks to prevent damage to the engine. Usually, a diagnostic trouble code (DTC) will appear on the iDrive screen when this happens. Signs of a transmission problem include the gears getting stuck or slipping, error messages, or the engine revving without shifting. You might also notice delays when switching between gears. If you face these problems, find a safe spot to pull over and turn off the engine. Wait for about a minute before restarting the car; this might resolve the issue and enable you to shift normally, so you can drive to a dealership for assistance. Another trick you can try is turning on the BMW without starting the engine, pressing the gas pedal all the way down for 30 seconds, then turning off the ignition before attempting to start the vehicle and drive as usual.
If the BMW 318i e46 is experiencing transmission issues, you may observe various signs like vibrations or unusual noises while driving, a strange odor when the car is running, difficulty shifting gears, a stuck or unresponsive shifter, and fluid leaks. These problems could eventually result in complete transmission failure, ultimately rendering the vehicle inoperable.
When I shift from 1st to 2nd gear, everything is fine. However, when I try to shift to 3rd gear, it slips. If I keep my foot on the gas and shift to 4th gear, it drives normally. But as soon as I try to switch back to 3rd gear, it slips again and the RPMs increase.
Certainly! The car skips from first to third gear and often makes a grinding noise.
