Golf IV / Jetta IV :: Cold Air Intake Causing Water Logged?
I have a 337 with Injen cai. Well, I have since removed the cai due to the fact that rainwater/water during a car wash will run off the hood and onto the top of the inside of the drivers side fender (under hood) and eventually run down onto the filter itself, thus causing it to become water logged. This of course is not good. My question.. I've tried so many things to no avail.
View 7 RepliesGolf IV / Jetta IV :: High Pitched Noise / Whoosh Sound From Intake At Low Rpm When Car Is Cold
I have a 2002 jetta 1.8t with unitronic stage 2 ECU and following mods:
ssqv BOV with recirc fitting (so acts like a DV)
3 inch open downpipe
Water/Meth injacetion (-35c washer fluid)
Short ram intake+heat sheild.
Spring loaded wastegate.
So for a while now I could hear a very quiet high pitched sound along with a whoosh sound from the intake at low rpm when the car is cold, after 5-10 minutes of driving the sound changes to where i just hear the wooosh from the intake, no high pitched.
I went out, let my car park for about an hour or 2 in 0c temp. went to drive it,everything is fine, the car just hit 90c. so i floored it, but traction control was on and i have winter tires, so it barley got to 4k rpm. CEL started flashing, no throttle control, really annoying high pitched sound from engine bay with lightest touch of throttle. the trubo was boosting to 22 psi and holding up to 16 PSI at redline before this happened.
The car would struggle to stay at idle, massive vibrations. but after reeving to 2k+ rpm no issue staying at that rpm, no blue/black smoke from exhaust. i scanned it and only got misfire codes and this strange code : "17925 - power supply relay for ecu (J271 or J363): electrical malfunction"
I had to clear the codes 3-4 times and restart the car 3 times for the power supply relay code to go away. but all the misfires, the high pitched sound stayed. it would misfire while driving, then stop, and then again.
I also logged with VCDS, and flooring it from 2k rpm to 2.6k rpm resulted in 0 extra boost over idle (idle boost was 980mbar).
Is my turbo blown 100% because of that sound, or could it be something else causing the "dentist drill" sound? And what about the power relay issue for ECU, could this cause any of the symptoms?

So I had a hose come apart that is located under the intake manifold on my 1.8t. It's some type of air hose because I can hear and feel the air coming out when the car is running, and it's also making my car run rough and miss, mostly at idle.

I recently noticed a rattling coming from my intake manifold and with little research I discovered it was the intake shifter rod. I ordered the new updated bushings and installed them today and the rod continues to rattle just as bad. My car only has 90k and I am unsure what to do to fix the noise. I am hesitant to order a whole new shifter rod because it could be the manifold itself too worn. I am just curious if there is anything that I may have overlooked or if there is anything I can do.
View 4 RepliesGolf IV / Jetta IV :: Clogged Air Intake Before Air Filter
I only removed the standard air filter housing and fresh air intake yesterday to get access to the VSS and Speedo drive to change the differential fluid on my 01M transmission. I was surprised to find that there was a fine metal mesh screen installed at the entrance to this air intake tube. This would be located behind the battery and just behind the drivers side headlight is where this metal mesh screen is located. Anyways, this was easily disassembled to clean and reassemble. However, I did not find anything about this mesh screen in my Chilton's manual, but this is now on my annual maintenance list. I added some pic's to show the clogged air tube. There was also a spring loaded door on this air intake tube...
View 5 RepliesPassat (B5) :: Oil Inside Intake Hose / Seal Leaking
195,000 miles on a 1.8T I removed the intake hose that connects the inter cooler to the throttle body and noticed a bit of oil inside the hose. I was guessing it may have come from the turbo due to a leaky seal, but this is strictly a guess. The car doesn't consume too much oil (maybe a quart or less between changes). What is the life expectancy for a turbo?

Had a large puddle of coolant under my '05 X this afternoon after work. Seems it's leaking from the Y connection coming off the heater water control valve. See first pic.
I think it's part number 18472 (labeled with the circled 1) on left side in pic #2. Need to confirm this is the right part and the full part number?
Lastly, how the heck do you change this hose? It's tucked up under the cowl and looks like difficult.

Golf IV / Jetta IV :: 2003 - LED Dome Light Installation Malfunction
Upon installing LED interior lights in the dome lighting in my 2003 Jetta GL 5 Speed, my power door locks, power windows, interior lighting, and license plates lights no longer work. I looked at fuse 14 (the fuse associated with interior lighting) and it was not blown. I also tried replacing the LED lights with the lights I had removed while putting in the LEDs, and everything still does not work. Another thing to note is that during installation, the 3 lights in between the drive and passenger seats in the front worked when LEDs were inserted into them. It was not until I replaced the passenger side rear light with an LED that all of these malfunctions started to occur.

So I just bottomed out really hard and I pulled over to a gas station to check out my car to see if I busted anything. I noticed on the way to the gas station that for the first two times I hit the brakes hard there was a clunking noise but now it went away. Onto the leaking part though, there are two hoses that run just along the inside of the frame on the passenger side just behind the wheel and one of the lines is leaking a lot of water. What these lines run to/from? I'm going to get the car on the lift tomorrow.
