E46  3 Series BMW Produced from 1999 thr

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 e46 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 for the M52TU and M54 motors.

 

Double Vanos Seals

2.5L and 3.0L M52TU and 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, who 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 M54s, 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 e46 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 e46 chassis and should be replaced every 60K miles.

 

Automatic Transmission Service

Lifetime fluid is a myth and any true Bavarian enthusiast knows that transmission fluid and filter needs 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.

 

Window Regulators

These are notorious to fail on all E46 cars and we have perfected the replacement with the right OE quality parts are a huge discount.

 

Differential Bushings

A tough job for most, we have perfected this repair over many years of experience, performing rear-end upgrades.

 

Convertible Top Service and Repair.

We made ragtops our specialty and over the years, have honed in on the trouble areas with these complicated systems.
