Review on πŸ”§ Fix & Restore PCV Diaphragm with Dorman 917-064 Repair Kit for Audi/Volkswagen Models (OE FIX) by Michael Hellewell

Revainrating 5 out of 5

Worked great, solved my problem with the high internal vacuum.

Fixed high vacuum issue. No CEL or other issues but my oil cap was stuck with high internal vacuum. I replaced the PVC membrane with a paint can opener which I highly recommend. Although my old diaphragm had no visible damage and no dirt in my system, this cured my particular problem. Looking back, I think the spring was harder on the old original. Perhaps a new lighter spring was the ticket. Not sure but 100% helped me, 5 stars.

Pros
  • Durable test results
Cons
  • Good
