 Interesting Bypass Valve News
I have just spoken to a workshop controller at a Mini Dealer. I have been told the latest recommended fix for yo yoing is to now replace the By Pass Valve with the latest version and then if necessary update the ecu, apparently the valve has been improved in the way it operates and on a Works car reduces the snap crackle pop you get on the overun.
Obviously reducing that particular noise is not going to please everybody.
Can anybody confirm this info? |
