Testing the Condition of the DISA, "Adjuster Unit" on BMW M54 M52 Engines

Whilst replacing the Crank Case Ventilation Valve, I removed the DISA valve as it makes getting access to the CCV a lot easier but also allows you to check on the condition of the DISA itself.

The purpose of the DISA is to raise the low and midrange torque "and" raise the top end power output. It is present on E36, E46, E39, E60 and Z4's with the M54 or M52 engines. It's a valve that opens or closes intake ports depending on the load.

Here is short video I made showing how to check the condition of the DISA and the various levels of failure.



Check back when I'll write up some tips and additional photos, on replacing the CCV, that haven't always been detailed on most other DIYs..

  2. Hi Oz Striker

    Great blog, Really enjoyed reading it. I have a 330ci convertible. Just wondering what size and type of LPG tank you have installed? I am going to convert mine to a Prins system but not sure what the largest do-nut tank that can be fitted into the spare wheel well. Thanks very much. Nick

  6. The BMW M54 is really an impressive model. Those who are planning to purchase it should also keep in mind the Repairing and Servicing Manuals of BMW are also available. These manuals guide each and every step of repairing in detail with the help of diagrams.
