PRODUCT DESCRIPTION

The BMW M56 is a 2.5 liter 184 PS (135 kW; 181 bhp) straight- six engine. It is a re-engineered version of the M54B25 engine, 
manufactured in order to meet SULEV regulations in 4 US states.



Do I have an M54 or M56 Engine?

The BMW 325i/325Ci models from 2002-2006 could have been equipped with one of 2 different engines; the M54 engine or the M56 engine. 
The M54 engine is the standard engine for the 325i models. 
The M56 engine was developed to meet the Super Ultra-Low Emissions Vehicle (SULEV) standards 
in several states (California, Massachusetts, New York, Vermont and others). 
Since the 2 engines were produced concurrently, you need to determine which engine is in your 3 series. 

A quick check of the oil fill cap location will help you determine which engine is in your BMW.


Our repair kit in this listing addresses the common failure of the BMW DISA M56 engine intake adjuster valve unit. 
Our components described herein with the assistance of our supportive instruction media will allow you to replace the faulty components 
which always fail within the DISA unit, without having to replace it with another OEM part that is going to fail again 
due to the same manufacture faults. An extremely common fault corrected by our repair kit.

SYMPTOMS OF FAULT

The symptoms of this fault are very obvious; there is a rattling noise coming from the DISA valve, SES light is lit and getting a lean mixture fault or rough running at idle. Displaying DTC codes and a loss in low end torque. There may be a rattling, buzzing or clicking noise coming from the engine. Fault codes: lean condition(P1083, P1085), front oxygen sensor lean (P1090, P1092) oxygen sensor slow response (P1087, P1089) and cylinder misfire (P0311-P0316) fuel control mixture lean (bank 2 sensor 1) and p0174 system too lean, showing?

THE FAULT

The original plastic Disa valve components wear and often snap causing the symptoms noted above.

The pin retaining the flap can also pop out entering the engine! The likely cause of the faults noted above and most common cause is the weak plastic components within the DISA valve unit vibrating together and wearing causing the flap to operate at the wrong times and eventually leading to destruction of the flap plate. The pieces of this flap can even enter the engine often causing severe engine damage; likewise the metal pin that holds the flap plate in position can vibrate loose and enter the engine.

THE SOLUTION

Fit our improved design billet aluminium flap kit, designed to never fail, save the cost of a replacement DISA valve which will only fail again.

Using our kit the weak components of the DISA valve the flap and crank lever are replaced with our many times stronger billet aluminium parts, retained by our precision machined screw which tightly retains the two components together; eliminating wear and the need for the retaining pin which can enter the engine. Our part is completely redesigned to never fail- OEM clearances are reduced minimising vibrations in the part preventing any future failure. Our kit also includes a high temperature Viton 75 O-ring to make a good seal between the DISA unit and the manifold eliminating any air leaks.
