Camshaft and Cam Follower Warranty Extension

 

In addition to the pcv and intake manifold motor, Volkswagen also extended the warranty on the camshaft, cam follower and high pressure fuel pump to 120,000 miles or 10 years. As before, they will reimburse any out of pocket expenses related to failure of any of these components provided you have proof of payment and repair. Keep in mind this does not cover replacing followers, only components that have failed or have insufficient hardening. Look through the following letter and see what applies to you.For more information, check out my other posts:Cam Follower Camshaft and Cam Follower Warranty Extension

Camshaft and Cam Follower Warranty Extension

November – Quick Update

Sorry it’s been so long since I’ve written a post, things have been a little quiet on the MKV front. My car is in a place where I like everything on it so I’ve been leaving it alone. The platform is getting older but that doesn’t mean new things aren’t being developed! There are a few particular developments that I want to talk about regarding fueling and cam follower improvements. One company has decided to research and produce a replacement follower that should all but eliminate excessive wear from this part. It has not been released yet but is due to show up in December. I’ll have more information as it becomes available.

Fuel Filter – Latest Revision – 1K0201051K

6.6 Bar Fuel Filter - Part Number 1K0 201 051 K

There is a new revision for the fuel filter with a 6.6 bar pressure regulator versus the older 6.4 bar regulator. Since I was due for one, I purchased one from TheVWPartsStore.com for about 35 shipped. The filter looks no different from the older version except for the 6.6 bar marking. The part number is 1K0 201 051 K.

6.6 Bar Marking - 1K0 201 051 K

The factory interval is around 40,000 miles I believe. The one I changed out had about 20,000 miles on it. When I first changed out my fuel filter, I noticed that a lot of the gas that spilled out was a muddy brown color. This time there was none of that.

Here’s a link to the fuel filter DIY. Excellent instructions. As always, when working with fuel, be careful. Work in an area with good airflow and no sources of ignition.

Hot Weather Fuel Cuts

1K0 919 051 CL

Since the weather is getting warmer again, some of the older MKV’s may begin to experience failure/overheating of the low pressure fuel pump.  I had this problem last summer. This issue often comes up in hot weather and long distance driving.  The low pressure fuel pump begins to overheat and then cuts out, starving the high pressure fuel pump. Acceleration is completely cut and you have to pull over or slow down.

If you’re experiencing fuel cuts in the heat or during long distance driving, take a look here for some more information. You may need to replace your in-tank fuel pump with the latest version.

Cam Follower 45,000 Mile Checkup

Second Cam Follower, around 45,000 miles on it. The car has almost 100,000 miles now.

I pulled the cam follower to check how it was doing.  It’s been quite a while since I last checked.  I’m estimating the total mileage on this to be about 45,000 miles.  This is only the second cam follower this car has seen.  Nonetheless, the wear is excellent and I’m popping this one back in.  I’ll check back in 10,000 miles, which this should easily last.  The DLC coat is still not completely worn through in the center.

Cam Follower Warranty Extension

Good news everybody! VW of America has decided to extend the cam follower, high pressure fuel pump, and intake camshaft warranty to 120,000 miles or 10 years. I received a letter in the mail. It took a while but VW finally did the right thing.

I’ll load the letter once I get it scanned. documents added below

Intermittent Fuel Cuts – Low Pressure Fuel Pump

August 17, 2011 Update: 

It seems that the CL part number has now been superseded by 1K0 919 051 DB. I don’t know what the changes are or if the change was spurred by a problem with the CL number. Info from this thread.

As the 5th generation cars begin to age in the U.S., a couple of newer problems are beginning to rise up.  One really annoying problem is the low pressure fuel pump cutting out intermittently.  It leads to the high pressure fuel pump starving of fuel and then the engine loses power for a few seconds.  Utterly annoying and it can be dangerous if you’re traveling at a good rate of speed and happen to slow down in the far left.  It can be difficult to get onto the shoulder.  It tends to happen during a long drive in hot weather.

A newer updated pump (Part Number : 1K0 919 051 CL) is supposed to help with this problem.  This is not located in the engine bay, unlike the high pressure fuel pump.  This one sits underneath the rear seats.  It is easy enough to replace and there are a few DIY’s floating around.  Here’s a good one from the Golfmkv forums – In-tank fuel pump replacement

1stvwparts.com has the best price that I’ve seen so far at $180 dollars plus shipping.

Before changing the fuel pump though, you might want to check whether your thrust sensor has been updated to the latest revision.  This sensor sits on the passenger side of the high pressure fuel pump.  06E906051K is the part number for the newest thrust sensor revision.  If this solves your problem, you’ll have saved around 120 dollars.
