PCV and Intake Manifold Motor – Volkswagen Warranty Letters

I finally got around to uploading the warranty extension letters that Volkswagen sent out regarding the pcv and the intake manifold motor. These letters were (or are still) being sent out to owners to inform them that the warranty on these parts has been extended to 120,000 miles or 10 years. If you have replaced any of the affected parts from you own pocket, Volkswagen will reimburse you for the costs, provided you have all the receipts still.For more information on the pcv valve, check out my previous post:PCV Valve & Breather TubePCV and Intake Manifold Warranty Extension

PCV Valve and Intake Manifold Motor Warranty Extension

06F129101P Front Detail

I recently received a letter from Volkswagen of America stating that the warranty for the pcv valve and intake manifold motor has been extended to 10 years/120,000 miles. You will also be eligible for reimbursement if you paid for repairs on any of these parts. Signs of pcv failure may include loss of boost pressure, poor idling and sometimes oil being pushed out of the oil cap. Intake manifold failure usually results in poor cold starting and sluggish low end performance. Either case can also cause the check engine light to come on.

Tech Tip – Quiet Down A Noisy Or Rattling Boost Gauge

If you have a mechanical boost gauge, even the best ones can rattle under certain rpm / load conditions.  It happens because of the minute pressure fluctations that occur in the intake manifold when the intake valves open.  The common solution is to add an inline vacuum restrictor (see image below).  You should be able to pick this up from any auto store. Sometimes this doesn’t get rid of all the noise though.  The key is proper placement.  I picked this tip up in the MKV forums from the someone with the username Plac.

Here’s how:

The inline restrictor has one end that is clear while the other end contains a brass piece with a small hole in it.  This dampens the movement of air in the boost line.  Place the end with the brass restriction about 5-6 inches from your boost tap facing the intake manifold.  This should get most of the noise/vibration.

I’ve had this restrictor in for quite some time (along with a miniature fuel filter to help quiet things down even more) but I would still get vibration under certain load conditions.  I simply moved it according to this tip and it is silent for all intents and purposes.  I haven’t heard the gauge rattle since moving the restrictor.  Hope this helps you as well!
