Like mentioned above, the fan control module (which also controls the A/C compressor clutch) is under the frame rail, below the battery tray. I have a video showing how to replace it. Maybe this will help?
PS - The video also shows how to replace the fuse panel on top of the battery. One of...
If you wanna get fancy, IDParts sells an EGR coolant bypass kit. Here's a link: https://www.idparts.com/egr-cooler-coolant-bypass-kit-alh-speed-3b0122291b-alhegrcoolerbypass-p-2170.html
It's been over a month since the valve cover gasket install. I was curious to see if the gasket was working. So I popped the engine cover and took a look.
SPOILER ALERT: The gasket is holding! Nice. :cool:
The valve cover gasket on the Jetta was leaking. Instead of replacing the whole valve cover assembly, I decided to try the BEW gasket retrofit. Spoiler Alert: it was a hassle. But it saved me some cash.
A couple photos:
Here's what the valve cover looks like, with the gasket removed...
Well, this is disappointing. The transmission mount only lasted about 30k miles. To add insult to injury, the replacement was also a little loose. Not gonna lie, I'm thinking about getting a tube of urethane window sealer. :cautious:
Anyway, here's a video of the mount replacement.
The Jetta was overdue for new shocks and struts. Unfortunately, I forgot to buy bump stops for the shocks. So I could only install the struts. I'll be installing the shocks tomorrow. I used a couple shortcuts to make the strut replacement easier.
You can remove the engine cover, grab the valve cover, and try to physically push the engine back and forth. If it moves more than a few millimeters, the mounts are worn out. (or you're super strong!)
It's been awhile since I posted anything about the Jetta. In a way, that's a good thing. That means the car has been reliable.
However, I decided to check the catch can again, to see if it's working. I checked it a few months ago, but forgot to check the intercooler to see if oil is still...
I didn't think to mention this, but yes... I agree with the above. The VNT mechanism needs to be completely disassembled to clean it properly. After doing all the work to get the turbo out and get the turbine housing off, it would be silly not to take out the vanes and clean those as well.
It's probably the camera angle. The blades were undamaged.
Separating the cartridge from the manifold was a huge PITA. It took several cycles of heating and dousing the bolts to get them out. I think I used PB Blaster, but don't get hung-up on brand names.
After the bolts were out, it took...
I've been down this road already. A couple comments:
1) The Mr. Muscle brand of oven cleaner does not have magical properties. But it does have sodium hydroxide (aka Lye). Any oven cleaner with sodium hydroxide will do.
2) Depending on how gunked-up the turbo is, the "oven cleaner down the EGR...
Same here. I could tell when my Jetta was going into limp mode, because the car would suddenly feel sluggish and the boost wouldn't go above 3-4 PSI.
I went through the limp mode checklist (search for it in this sub-forum), and found the problem. In my case, the vacuum actuator was shagged, and...
