BMW N54 turbine Westgate Repair Kit

Original turbine numbers that the repair kit fits: 11657593022, 11657593020, 11657593015, 11657593017

One of the main problems of BMW N54 engines after 100 thousand km is the wear of the turbine overpressure relief system (Westegate, Westgate). They are popularly called "gates", "dampers" of the turbine. The reasons for failure are wear and tear associated with high operating temperature, constant temperature fluctuations, as well as aggressive working conditions (sand, water, dust and dirt from the street fall on the traction). The main signs of a worn-out westgate on the BMW N54 turbocharger:

• Rattling from exhaust manifolds
• Increased gasoline consumption, thoughtfulness of the engine, reduced acceleration dynamics
• With a sharp long-term acceleration after 90 km / h (for example, when overtaking) The ECU of the N54 motor records an error about a low boost pressure, the Check Engine may not light up at the same time.
• Errors on reduced boost pressure
• Errors in ignition failures at high and medium engine speeds in certain rows (Cylinders 1-2-3 or 4-5-6 - wear of one of the turbine dampers N54) 

The manufacturer offers to replace the turbochargers BMW H54 vsbore. We also suggest replacing the Westegate BMW N54 repair kits. Installation on the BMW N54 engine is not possible without removing the turbines, the process is quite time-consuming and takes a lot of time - for this you need:

1. Remove the turbochargers from the motor (it is more convenient with the removal of the motor, but with certain skills it is possible to remove without dismantling the motor from the body) check the backlash on the turbochargers N54, the condition of the catalysts)
2. Unscrew the Westgate BMW H54 vacuum regulators
3. Dismantle the old BMW N54 flap with a grinder, noting the position relative to the turbine.
4. Attention! Installation of dampers is impossible without an argon-arc welding machine. Install the new flap in the position previously marked during disassembly. Weld the lever to the rod.
5. Screw on the vacuum regulator (replace worn vacuum lines, clean or replace electromagnetic pressure converters N54)
6. During installation, it is necessary to use new oil supply hoses and hoses of the cooling system, as well as all seals and gaskets.
