E83 X3 BMW Produced from 2004 thru 2010 as: X3 2.5 X3 3.0
Oil Separator/PCV Valve
This 100% failure rate item and is not always obvious unless your car has “system too lean “codes and burns oil. Every single X3 BMW is going to have this issue and if you haven’t’ replaced it in the last couple of years, it’s better to get it done sooner rather than later, as it is one of the most common causes of death of the motors.
Automatic Transmission Service
Lifetime fluid is a myth and any true Bavarian enthusiast knows that transmission fluid and filter need to be changed at least every 60K miles. BMW dealers do not perform this service, ever, so if you are driving a car without evidence that this was done, this is service should be your top priority.
Differentials and Transfer Case Service
Similarly to transmissions, transfer cases and differentials need to be serviced at least every 60K miles. BMW dealers do not perform this service, ever, so if you are driving a car without evidence that this was done, this is service should be your top priority.
Double Vanos Seals
2.5L and 3.0L M54 motors are known to wear out Vanos seals prematurely and besides a loud rattle, affect the timing. We have a strong partnership with Beisan Systems, which produces a repair kit well above OE specifications that eliminate this issue for good.
Cooling System Service
Water pump, thermostat, coolant hoses, and overflow tank. An Achilles heel of most BMWs, cooling systems are notorious for failing and causing severe engine damage. We highly recommend preemptive replacement of critical components in the cooling system before they fail, usually every 4 years or 60K miles.
Valve Cover Gasket
Manifested by the smell of burning oil, this is an easy repair that is often neglected and can cause an engine fire, as the oil drips on the catalytic converters.
Oil Filter Housing Gasket
This 100% failure rate item is not obvious, as most owners can’t see the source of the leak. Every single BMW is going to have this issue and it’s better to get it done sooner rather than later.
Control Arms and Bushings
Usually neglected, these items wear out prematurely on all X3 chassis and should be replaced every 60K miles.
These are notorious to fail on all X3 cars and we have perfected the replacement with the right OE quality parts are a huge discount.
