So the other day I replaced my N75 valve and upgraded my DV to the Forge 007. For some reason the turbo doesn't spool like it did before, it's lost it's pep.
I've tried the Yellow and Green springs, also I tried them with the shim too. No luck. The car got turbo back exhaust, intake, and stage one program.
Just today I noticed my car boosting to around 1.2bar instead of the usual 1.4bar. The car is boosting to around 1.2 then dropping off to around a bar.
The only thing that I did was install a forge splitter. I presumed that the splitter valve was the issue and promptly put my 007p back on but still had the same issue.
During the process of adjusting the splitter valve I got limp mode several times. I much prefer the 007p and will be keeping that and selling the splitter. What may have happened?
Where is this diverter valve located at ? Is it under the car?
View 10 RepliesHaving issues with the stock one that came with our cars I think I may be leaking from the diverter valve. I was searching the forum but couldn't find the answer but when I hit the gas I can hear I would say like the diverter valve is constantly releasing the air and the power pretty much plateaus doesn't keep pulling like it did I'm assuming the diverter valve because i know there were issues of them before but i wasn't sure if they had the same issue in the mk6.
View 24 RepliesI currently have a 2011 DSG. I purchased it last year and when I test drove it I did not notice any unusual sounds coming from the motor/ drivetrain. However since then I have noticed that the car makes a grinding like sound when my car is around 2k-3k rpms, its especially loud under load. Its a very audible sound, like something is grinding in the transmission- Everyone that has been in my car can hear it, and it only happens at low rpms. Anyway, I took my car in once to service and I mentioned it, however the tech said he could not hear anything.
I honestly think that I got louder since then so I took it back and the shop foreman came out for a drive with me. So the guy hears the sound, but says that its the diverter valve and that its supposed to sound that way. He tells me its because the cars now have a metal valve and that its louder. I had a 2002 A4 1.8t and it never made a sound like that, even after chipped. So Im a little worried that its something else and I wont be able to get it fixed under warranty, or maybe im just paronoid and the DSG sounds like this.
Looking to have it installed? I bought it but I haven't installed it yet...
View 2 RepliesThe CEL on my Passat came on. When I scanned it with VAG-COM, the following fault code was displayed:
000665 - Boost Pressure Regulation
P0299 - 002 - Control Range Not Reached
The car also felt like it lost its power in some way, especially when the turbo kicked in. So after some research, I found out that the Diverter Valve was causing this issue. Rubber diaphragm on original valve was made from rubber and was torn. I replaced it with upgraded valve and wow what a difference!!! Very easy to do, great write up link below.
DIY Diverter Valve Replacement for 2006 VW Passat 2.0T
If your diverter valve is bad, will it throw a CEL or not always? I don't have a CEL but sometimes I feel like there is a lag in the boost. Wondering if the diverter valve is bad or not.
View 6 RepliesWas cruising on the freeway and all of a sudden my exhaust sounded like it has a leak!!! I gave it some gas and it got louder but the car didn't pull like normal??? No check engine light or anything crazy. I don't think the inter cooler pipes blew off because the engine didn't shut down and I was on cruise mode.
Its sounds like the turbo wants to spool but cant hold boost, can this be the diverter valve leaking or its blown?? I haven't had the chance to check which diverter PN# I have but Im pretty sure its the stock OLD version. I am the 3rd owner. 07 Passat FSi variant with 36K miles.
I hear the 07 FSi are know to have bad or weak Diverters.... I know I needed to go with a stonger TSi Diverter which I hope is the problem here....
I've lost all power steering about a week ago. I checked all the lines the return is bring fluid up from the pump and the res is flowing into the pump.
A) should I replace pump?
B) look into other things that could be causing the issue?
Driving home tonight and my car lost all mechinical power, electronics still work. Car turns over but will not start, also hear a clicking noise coming from the driver side of the engine when car is being turned over.
View 1 RepliesMy friend's Jetta was running fine. One day about to drive out of the driveway it started doing 2 things:
1. Felt like it lost power braking, just stopping by manual effort by pushing down pedal hard.
2. Engine stalling unless you keep the gas pedal depressed and holding the engine to about 3,000.
Car currently sidelined until this is fixed... Having the brakes go like that at the same time is strange so where to start. Brake fluid level is fine.
2000 jetta 1.8t ... Yesterday driving home from work (1.5 hr drive and it was 25+ degrees) my car died on the highway just before I made it home. Just lost power all of a sudden with no warning signs before and no overheating. No lights came on I just felt sudden loss of power and pulled over and turned the ignition off and it wouldn't start again. Just makes a high pitched whining noise and won't crank over. I just found out the other day that both O2 sensors need replacing but I can't see that being the reason.
View 5 RepliesI have a touchscreen that the dealership provided me but with the catch that I've got to install it myself, pretty sure it has something to do with the state the previous stereo was taken out, all I'm left with are a cluster of wires none of which I know are for what.
View 2 RepliesSo I installed a Forge Wintake yesterday and my car responded well to it yesterday. Everything was working great and then on my way to work this morning a CEL turned on and it is misfiring on at least one cylinder. I checked all of the connections to my coils, the MAF and my First O2 sensor. Everything looks fine. My Car is a 2012 GTI. I also have a APR stage 2 flash and a Raceland Catless down pipe.
View 14 RepliesI finished installing an auto out of a 1999 beetle into my 2000 golf. I used the beetle TCM now it wont shift out of 3rd. If I manually start in first it will shift up to 3rd but nothing past 3rd. I had it scanned with a generic scanner and these are the codes. P1780, P1783, P0725. I researched the heck out of this and I'm not sure what to do. Do I need to take it and have a vag com hooked up to make sure the ecm and the new tcm are talking? It seems others have had these issues and I thought it might be solenoids but that's not what's coming up.
View 2 RepliesOkay just installed a newer 24v into my existing 24v VR6 GTI both with 135k. I have heard the motor run before it was pulled and sold to which sounded fine. Upon receiving the motor I put new timing chains, guides, headgasket and new gaskets all around. The timing was right on the mark and I tightened everything up to torque spec and I'm getting this noise which sounds like it's from the timing cover area. A code just popped on which I'm going to scan as soon as I get my hands on one. The car was running great for about 20 minute and I shut it off then turned it back on about 5 minutes later and experiencing these scary noises. I tried pulling each individual coil with no results to get the noise away. What could this be?

99 Jetta, installed a new AC compressor a month ago, has been working great, not clutch will engage for a few moments, then turn off for a minute, then engage again. Seems, like there is Freon in there by the gauge on the low side.
View 4 RepliesLast Saturday, my mechanic friend and I spent the day installing WRD coils on my 2003 Wolfsburg edition Jetta. Took us longer than we thought but we got it all done and we set them at 3/4 max for lowness. I don't want to go any lower and I will probably raise a little bit soon.
Anyways, when I started driving I noticed a rear clunking sound, it's especially noticeable at slower speeds. Every single tiny little bump and sounds like someone is dropping boxes in my trunk. I checked my trunk and took everything out and that still didn't work. When my car is stationary and I get out and push on the rear to test the shocks I hear the sound.
After installing a new crank position sensor on my 05 GTI 1.8T would I have to recalibrate my ECM, my car will not start.
View 2 RepliesI recently installed a k04 turbo, when I try and accelerate hard my wastegate just seems to open up very quickly without building much boost. I don't have a boost gauge or anything like that installed. Do I start by adjusting the wastegate actuator, or install MBC. Pretty new to this still.
