1990 Bmw E46 problems
The fourth generation of the BMW 3 Series range of compact executive cars is designated under the model code E46, which was produced by the German automaker BMW from 1997 to 2006, and was the successor to the E36 3 Series which ceased production in 2000. First introduced in November 1997, the E46 was available in sedan, coupé, convertible, station wagon and hatchback body styles. The latter has been marketed as the 3 Series Compact.
The M3 performance model was introduced in June 2000 with a 2-door coupé body style, followed by the convertible counterpart in April 2001. The M3 is powered by the BMW S54 straight-six engine with either a 6-speed manual or a 6-speed SMG-II automated manual transmission.
The E46 line-up was phased out starting from late 2004, following the introduction of the E90 3 Series sedans. However, the E46 coupé and convertible body styles remained in production until August 2006.

Common 1990 Bmw E46 problems
The BMW E46, produced from 1997 to 2006, is known for its performance and luxury. However, as with any vehicle, it is not without its common problems.
- Weak Rear Shock Mount: The rear shock mount is another area that can use reinforcement. The original design focuses on the bottom of the mount, where the weight of the car sits, but has no emphasis on the top. This makes unloading the suspension potentially hazardous to the other side of the shock tower. Reinforcing the rear shock mounts can help prevent this issue.
- External Door Handles: Some BMW E46 owners have reported issues with external door handles that stick in the open position. This problem can be caused by various factors, including wear and tear, debris, or mechanical failure.
- Failing Exhaust Particulate Filters: Owners have also reported issues with failing exhaust particulate filters, which can cause a decrease in performance and fuel efficiency.
- Brake Servo, Airbags, and Power Steering System Recalls: BMW has issued recalls affecting the brake servo, the airbags, and the power steering system of the BMW E46. These recalls are due to potential safety issues and should be addressed as soon as possible.
- Turbocharger Problems: Problems with turbochargers are not uncommon in the BMW E46. These issues can cause a decrease in performance and fuel efficiency and may require expensive repairs.
- Front and Rear Suspension Components: The front and rear suspension components of the BMW E46 can wear or even fail, causing a decrease in performance and safety. Regular maintenance and inspections can help prevent these issues.
In conclusion, while the BMW E46 is a high-performance and luxurious vehicle, it is not without its common problems. Regular maintenance and inspections, as well as addressing any recalls or issues as soon as possible, can help ensure the longevity and safety of the vehicle.
