Differenzierte Sauganlage - and because German's can't pronounce this either, BMW just took the first two letters from each word and called this the DISA Valve. BMW's engineers discovered that the air path through the engine system has an impact on performance. In an effort to improve performance, BMW released the DISA valve in 1995.

The DISA valve on my son's '95 318i is controlled by a "vacuum box" (that's how it is listed on Real OEM). The vacuum box was faulty and the valve was in "high rpm" mode all the time. I fixed it and frankly, from the seat of my pants, I could not feel any difference in the car's performance . . . but I drive a 328 manual every day so his 318 is

Hi everyone, seems that my DISA VALVE is busted (says Zeemax). Do these faults appear under a diagnostic? Anyhow, they replaced mine with a 2nd hand unit but the problem still persists. So either that was not the problem (rough idle, on idle the revs will drop and sometimes cut out - this DISA Valves are Air Intake Control Valves introduced by BMW to improve performance by controlling the path or air as it flows through the engine. The name stems from the German ‘Differenzierte Sauganlage’ or Differentiated intake system in English. We will be posting a full TechASSIST bulletin to cover them in more detail soon. Description.

The DISA valve is a common failure on the M54 BMW engines and is caused by the poor materials used in the manufacturing process in a couple of the key valve components. The three parts of the DISA are the flat plastic flapper valve, the bell crank lever that rotates the flapper, and the vacuum pot, all made of glass reinforced nylon.

The valves don't communicate with the ECU other than to switch position when powered. There are some YouTube videos about testing and repairing the disa units so that might be useful to look at. The DISA valve may be the cause BMW N52 small DISA valve replacement without removing the intake manifold which is a very easy DIY task to complete at home.

With proper engine maintenance, intake and exhaust valves usually provide thousands of miles of good service. Engine valve problems begin to occur when your engine is subjected to overheating, lack of lubrication or over-revving. Bent valve

Located inside the intake manifold, it gives better torque at low revs by closing keeping the intake runner long but after about 4500rpm, it opens up by and makes the intake runners shorter for more horsepower. This is the lower DISA valve located in the intake manifold of the N52 engine in the E90 330i, E83 X3 3.0si, and E86 Z4 3.0si, as well as the N51 engine in the SULEV E82 128i and E9X 328i. DISA is "Differential Intake Air Control", also known as variable length intake runners. The kit is priced at approximately 1/3 the retail cost of a new DISA valve from a BMW dealer. Remember, a new stock DISA can still fail prematurely.

The electronic controls in the solenoid valve are what makes it possible to control it this way. From vehicles to industrial tools, there are many products that use pneumatic systems. This means the system takes compressed air and uses it to control energy as it moves through the system. However, without pneumatic valves, these product Industrial solenoid valves are easy to find when you know where you're looking.
