Diagnose: Engine Click
 
So yesterday I noticed this clicking noise when the engine is running...

Video...
http://www.youtube.com/watch?v=8guB7sLGoSU


A few weeks ago I had screeching but I fixed that by replacing...
Both Tensioners
Both Pulleys
Water Pump (Pulley Only w/ Aluminum)
Both Belts
... then everything was quiet and smooth.

A week ago my battery went dead at work (wouldn't go beyond click noise) so I got jump started by a VW then drove home. I bought a new battery and swapped it out. Car started right up fine all week and still starts fine.

What could be clicking?
Can the alternator wheel/pulley be clicking?
I had plans to replace the water pump first.
Could the Water Pump be clicking?

seems pretty easy to replace... anyone have part # off hand?


FOUND IT: Adjuster unit #11617544805 about $200
I'm gonna test it by unplugging the sensor when i get home but I did find the part.

disa valve is above your throttle body. it is located in the center of your intake manifold (on the side)

i saw some youtuber videos on it. Seems simple enough and I looked closer when I got home. It definitely sounds like its right up in that area. Its hard to tell because its up in the air intake area so it kind of reverberates. But it seems likes it is the Disa plus from other posts it seems replacing the Disa would be a great idea for improving worn performance anyways. I'm going to most likley order the part tomorrow and swap the sucker out.

Search for DISA on youtube, you should find a video where a guy shows you how to unplug it. You can do this while the car is idling to prove that it is what's clicking. Happened to me, I unplugged it, clicking stopped, plugged it back in, ordered a new DISA, swapped it out. Job jobbed. (Clean the MAF while you're in there)

There is also a DIY on this forum about how to repair the device yourself using some epoxy (no new DISA required), but it's dangerous because it requires loosening a pin that you then really really need to get secured back in place. If that pin ever comes loose it goes into the engine.

doesn't sound like when my DISA went bad. DISA is plastic but in your video it sounds like metal. Have you done your vanos yet?

Have I replaced DISA? no
Have I replaced VANOS? no

I unplugged the sensor to the DISA and the click remained. Here is another video with better sound.

SOLUTION: It was not the DISA... it was the Power steering pump. Replaced. Sound is now gone.
