Snake Oil Warning.
There are now hucksters coming out of the woodwork with assorted "fixes" for this problem.
At the present time, I know of no validated and proven fix for the CP 4 problems.
The only known "fix" is the redesigned pump --- and I will wait until the end of the year before I conclude if that pump fixes the issues.
Furthermore, it is my longstanding opinion that no additives of any kind except those that are ENDORSED IN WRITING by the OEM (Ford, GM, VW, etc.) and SOLD by them under their own Brand, should be used.
Use of 3rd party "cures" or "fixes", especially additives will almost certainly be legitimate grounds for denial of warranty.
Ditto for use of approved additives improperly (e.g. overdosing).
Beware of anyone coming around claiming that their 3rd party additive or their gadget solves the CP4's problems.
If that is the claim --- get it in writing from the manufacturer of the additive AND get an OK in writing from Ford or GM or VW to use it.
Or you have no one to blame but yourself when the CP4 fails on you.
And no one to blame when they refuse to warrant it.
The last thing we need at this stage is to add in more unknowns.
