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!

AWE Vent Mounted Boost Gauge

AWE GaugeThe AWE vent gauge was one of my earlier modifications.  A boost gauge is another essential mod to this car, especially once you start modding a little bit.  The most important reason for having one isn’t so much as to know what your max boost is, it’s to find out whether you have a problem somewhere along the line.  Knowing whether or not you’re losing boost pressure can help you figure out what is going on with your engine.

There are countless options for siting a gauge.  AWE’s sits on the aforementioned driver’s side vent.  Eurojet’s upcoming solution also sits there.  VMR has a gauge that sits in the center stack vent.  New South has one that locates on the steering column.  For aesthetics, I think the vent gauges look the cleanest.  The New South gauge is cheaper than most but its placement on the steering column just looks plain ugly to me.

Edit 7/29:  I added a stock photo from AWE’s website to show how clean this thing looks.  I recommend purchasing the AWE gauge if you can.  Installation was easy enough thanks to precise instructions.  If you need help, you can ask your friendly neighborhood forum- i.e. golfmkv.com, or vwvortex.com

There are now countless variations of the vent pod gauge.  The best way to get a feel for them is to search the forums for some information.  The AWE gauge is still my recommendation and the gauge is now purely electric, eliminating any buzz that mechanical gauges might have.
