Passat (B6) :: Slipping And Thudding During High Boost After ECU Flash
Mar 22, 2013
Got a 6spd Manual. Just got Unitronic stage 2 about a week ago. Now i got probs with "slipping" "clunks" and "bumps" when I really get on the gas pedal. If I'm just smooth with the gas, no problems but it seems the newly added torque is causing something to freaking slip and it's scaring me every time it happens. Not to mention if I ever need power real quick, I'm just going to be standing still probably clanking down the road trying to get whatever it is slipping to pick up. I don't want to believe it's my clutch because this was just replaced in July 2012. How the can I stop this because I'm not enjoying it and lost all respect for my car for the moment...

I have a 98 passat b5 turbo. All done to it is k&n filter and exhaust.... I put a boost gauge on it and i only get 3-4 psi... is this normal? it sounds very low. Also a weird thing is that the boost drops off at high rpm.

I just got my 04 Passat chipped from APTuning 2 days ago and I was wondering if i need to tighten the gap on my spark plugs? Car runs wonderfully but in high boost it seems to sputter a bit, and i was hoping that tightening the gap was going to solve this issue. If i do have to tighten the gap, do i need to do this for each program? I have 4 programs on the chip (stock, 91 octane, 93 octane and 100 octane). I am sure that i'm going to keep it to 91 octane for 99% of the time.

So i have a '06 2.0t 6spdman passat. I started getting this high pitch sound (like a boost leak) when under hard acceleration from second gear and up. I went to the dealer today and they replaced my PCV system, and told me that was the noise i was hearing. Pulled out of the dealer like half a block and same thing happened. Then the tech went with me heard the noise, went back put it on a lift. And proceeded to just rev the engine. They say its my Intake system, yet I have had it on the car for 2 and a half years. Could it possibly be the DV???

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

I own a 2006 B6 and I'm just ticking down the list of common repairs... The last series started with boost lost anytime the car was pulling a steep hill or high acceleration. Eventually I lost boost altogether. I replaced the PCV valve and got back a little power but still no boost. This last weekend I replaced the DV valve. The old one was visually shot. The new one is the latest revision of that valve. Now, the boost will kick in, and cut out, kick in, cut out, in a rapid cycle during any acceleration. I double checked that it was installed and tightened (stripped the bolt heads) and reseated the electrical connection. I'm still getting the rough on/off of the turbo. If I slowly increase the acceleration it will act better, but that isn't a sure thing. I love the car, but I'm about to reach the point of pushing it off a cliff.

2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.

I used to think when I flash it'll turn on the high beam only but that's wrong.
Today I changed the high bulbs 9005 to a brighter pair trying to get a better DRLs, but when I tested the high beam by flashing I realized it turns both low & high beams on at the same time.
I have HID for low beam so that's not a good thing for me to flash. And I think I did it only one time in the past but now I won't do it again. Is it normal?

I have had the dead battery problem as well as the high / low shifter lights flash on and off. I also had a warning message called "workshop system fault" or something like that.

Golf mk7 2013 ... All of a sudden I lost the highbeam. Highbeam "flash" still works, but not constant high beam.
Bulbs? Are they separate between flash and constant?
Relay?
Stalk?

2 002 Jetta Bad misfire P0301 a bit long. 02 jetta gls with 2.0 AVH engine auto trans. over summer my brother overheated it & blew head gasket & valves. All parts listed are new between aug and now. I repaired engine as follows new head & bolts head gasket timing belt water pump coolant flange on drivers side new fuel rail and injectors car also has new coil pack, new VW plug wires and 1 week ago new iridium plugs my brother didn?t want car, so i bought it from him. Ran great after I rebuilt top end.
Car did 140 on the turnpike & ran great. once or twice while giving moderate to high throttle CEL would flash and I pulled P0300 as a pending code. Problem stopped after 2 days. last week after 4 hrs of idling(don't ask) started misfiring and CEL flashes constantly P0301 The misfire seems worse at idle and low speed. Car will get to highway speed but has bad pickup. This is what I?ve done/checked New iridium plugs Plug wires 4.5 ohms Coil pack is good and producing enough spark at each wire MAF sensor cleaned Cyl 1 compression good all injectors are clicking and when disconnected cause appropriate CEL error code Brought car to VW dealer for diagnosis VAG COM shows multiple misfire on cyl 1 Mechanic confirmed all the steps I took and components tested ok. He tried new coil pack, new plug and wire for cyl 1 and no change.

My fiance had 18's on her 2003 Toyota Camry LE 4cyl. We just replaced them with stock 15" wheels. About 2 months ago we replaced all the brakes and rotors as well. When we had the 18's on there, when we would hit dip we would hear it bottom out and scrape in the rear. Now that we replaced the wheels with 15" i haven't heard it do it at all but I do notice thudding noise going on in the back when we hit the slightest bumps. My guess is that the shocks and struts need to be replaced in the rear.

I have a 2nd gen 3sgte smoking on high boost, not on idle and not on normal driving. Could it be my CT26 turbo leaking? or head gasket? there is some oil residue on the compressor inlet. By the way it's a blue smoke.

I have a 2000 Dakota quad cab with a 4.7 l when I turn on either turn signal itll flash 2-3 times or sometimes not even flash at all when it does it just stops u can hear the flasher working . What to check and how to check/ replace parts I need to get it working again is there a flasher inside the steering column. or is there just a relay on the side where the fuses are ?

I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.

When I hit the gas and my turbo reached high boost (15 psi and up), it would slightly sputter and make an odd sound. I even noticed my exhaust made a different exhaust note than usual. While it sputtered the CEL began flashing. I then drove it normally (not high boost) all the way home and it drove completely fine. I'm gonna try and get my codes checked tomorrow.

Car started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.

I'm having a strange, very high-pitched, noise that seems to be coming from my turbo or (possibly) somewhere else in the engine bay. It sounds very screechy, and it may be paranoia, but I believe it also may have a slight metallic sound to it.
It all started yesterday after changing the thermostat housing for the third time in 2 days (autozone sold me a faulty, warped, housing that leaked after install). During this repair the engine never overheated (it did however leak fluid and go a little low) and the main point for replacement was a stuck thermostat. After finally getting it fixed I took it for a test drive and noticed the horrid noise after hitting a good amount of boost (no gauge installed). The noise occurs when boosting and doesn't happen when spooling in the 3k-4k range. I had no hint of the noise before this.
There doesn't seem to be any drop in performance and it still pulls hard. Hoping this to be a loose exhaust connection or boost leak. May be spooling sound escaping.
Mods:
- short ram air intake with an aem filter
- 3" turbo-back exhausted
- revo chipped
- 4 bar fpr

I'm having a misfire issue on my 1.8t. When I go into high boost I'm getting bogged down and misfiring.
I plugged in my obd2 adapter and it gave me a misfire on cylinder 3. I since cleared the code to try and see if it was a coil pack by switching it to another cylinder, but now the cel won't come back on although the problem persists.
I have recently changed the plugs and the car was fine. I then added a fuel injector treatment and the misfire started shortly afterwards. (coincidence perhaps). It's frustrating as I can't rule out coil packs as my cel won't come back on and my code reader is not displaying any faults.
I did previously have a cel with something about fuel trim bank 3? I am also sure I have a boost leak as the car whistles pretty loud under boost.
Also worth mentioning I have a bit of white smoke sometimes but I'm not using oil or coolant and they are not mixing either. I'm at the end of my tether with this car and just want to try get it back to normal.

The symptoms are as follows.
-No change in performance, functionality, or spooling.
-Loud intermittent screeching noise when building boost above 3500 RPM
-Can only describe the sound as air escaping from a tiny hole, VERY similar to warn brakes, that kind of screech. The intermittent part I would describe as if you were tapping your brakes (and they were screeching) rapidly, so on off on off very quickly.
-Also happens when I let my foot off the gas (Also above 3500 RPM)
-Car has CTS Turbo Intake, 42DD Downpipe, and APR stage 2 software.

I am currently stage 2, drive my car kind of aggressive on a regular basis, and now I hear a squeal under high boost, sounds like air escaping. Boost is not acting any different, I've come to the conclusion that the problem is most likely my revision D DV.
-What does failing REV D sound like???
