Upgraded Boost Solenoids?

phil200tdi · 10-12-2012, 03:58 AM

My car is significantly overboosting in the low to mid range (19psi on map 0).

This has been happening before and after new turbo replacement.

I now think this may be the boost solenoids playing up - I'll be testing them tomorrow. Just wondered whether I should buy OEM replacements or whether there are some recommended after market options to consider.

no aftermarket option as far as i know and i dont see how those could be upgraded. they work fine.

Ok great, I'll go OEM.

I know that there are aftermarket boost control solenoids available for Subaru's and EVOs etc which claim to lower WG Duty cycles etc. Just wondered whether there was anything similar on this platform.

Sorry for bump a very old thread... but I think that MAC Single turbo solenoid could do the job well. My mechanic (he's more a tuner than a mechanic tbh) will retrofit them to replace the OEM solenoids. I'll keep you informed.
