Disa Valve

[Paul345]

Hi everyone. Just looking for a bit of advice. I'm looking to replace both Disa Valves on a e85 n52 3.0si. Is there a brand that you would recommend, or should i just go genuine Bmw? Thanks

Are your valves damaged? Have you taken them out and checked?
They aren't cheap to buy, and if they aren't broken then perhaps dont replace just yet and monitor them?

Thanks for for the reply. No i haven't checked, car running fine! They reason why i was wanting to replace was im working through a list of jobs of preventative maintenance. Have already done a few gaskets and the both Vanos has been done recently.

Probably worth taking them out and checking first, they are I think stronger in the N52 engine over the M54. From memory a BMW one will set you back £300+ each.
