Golf/GTI VI :: Losing A Little Boost At Higher RPMs
I have been looking around for some boost information. I have come across a few threads that have boost graphs, but the images are no longer available. I have tried to get a hold of some of the posters, but no luck.
I only recently hooked up a boost gauge and have been monitoring my boost more. I had a slight feeling before I hooked it up that I was losing a little boost at higher rpms. Between 4500-5000 my boost drops from 18 to 15 and then from 5000-6000 it drops to about 10. I know it's sometimes normal for boost to drop at top end, but I'm not quite certain it's supposed to be that much.
I installed the Spulen Boost Pipe Kit hoping it may make some type of difference, but it's the same. What it might be? I have checked all my pipes as best as possible, but couldn't find anything.
Passat (B6) :: Check Engine Light Blinking Yellow And Loosing Boost When Accelerate
Driving on the highway today and when I started to accelerate fast I noticed my check engine light blinking yellow and also noticed loosing boost I think I can only reach maybe 10-12 psi, I am stage 1 revo and also it was 95 degrees out, what it could be, thinking misfiring? so would that mean new coil pack and spark plugs?
View 15 RepliesPassat (B6) :: 2006 / 2.0t - Boost Loss At Higher RPM
Car: 2006 Passat 2.0t 6mt - 81k miles. Has lived a grocery-getter life with an occasional romp on the back roads on the off chance the wife and kids aren't with me.
Symptom: Total loss of power (boost?) at at around 3-5k rpm and almost no power to accelerate (10-15sec to get one more mph). Service Engine light has come on twice, but clears with time or removal of negavive battery terminal. At low RPM range power is good, but suspect minor power loss. I'm only partly suspect on that last statement since I only drive it once a week. Idle seems normal, engine sounds normal at idle. Last week I did notice a barely audible whistle when boost is engaged. I have no access to a Vag-Com accept at the dealer.
The car let me down last weekend when I was smoking a jerk in a BMW that wouldn't let me get on the interstate. If it is the PCV and DV, where I can get one? Also, I'm not a tuner. I want OEM performance.
Passat (B6) :: 2.0T Automatic Shifting At Higher RPMs
Over the past couple of days, my wife and I have been noticing that our B6 (2.0 Auto/Tip) is shifting at around 4000 rpms. I'll probably be taking it in to have the dealer look into it but wanted to see if the community has experienced anything similar to the issue at hand.
It shifts (Appox):
1st into 2nd - 3200 rpms
2nd into 3rd - 3800 - 4200 rpms
3rd into 4th - 3500 rpms
4th into 5th - 3000 rpms
5th into 6th - 2500 rpms
Notes:
* the appox amounts above are at regular driving acceleration.
* while in Drive - "D" mode
* used to shift into all gears between 2500-2900 rpms
* doesn't shift nearly as smooth as in the past
Is it OK to slip into "Sport" from "Drive" while Driving? How about slipping into Tiptronic while using "D" or "S"?

View 2 RepliesPassat (B6) :: Sudden Boost Loss At 4000 RPMs
I just installed a boost gauge and drove the car a little and this is the readings I get. It starts off with 20 inHg and to normal street driving it goes up to 0 and down. However when I pushed it a little, the maximum reading I got was 11-13PSI (High RMP-almost redline). I am a noob in this boost department so Is this readings really accurate or is there something wrong? Recently i had some transmission work done. And since then the gas pedal feels heavier. I was convinced that it is from the new bushings but I feel like this is boost related. Because at 4000 RPM sometimes It suddenly looses the boost (Kick).
View 5 RepliesFord 6.7L Power Stroke Diesel :: 2013 - Turbo Noise - Loosing Boost Over And Over Again
I have a 2013 F350. Since it was new in August the turbo has made a chattering sound that sounds to me like the waste gate (if it had one) is opening and closing rapidly. Almost like its building boost and dumping it over and over again. Usually happens when it is in 6th gear around 1700 rpm under light load. It also does it from time to time while plowing snow. You can power through it or let off and it will go away. My local dealer where it was bought new put a new turbo on it and the problem still persists. The truck just turned over 8k miles and has been in several times in attempt to resolve the issue. They say that there are no codes on the truck nor does Ford have anything on their service web. My dealer claims that no one has ever had the issue.

This is a common problem. Mine goes to dealer in the morning for it. I haven't seen any recent posts within the last year on this. Did ford ever find a fix for my problem? When going up hill at low rpms I lose boost and hear the stutter out the intake..
View 14 RepliesFord Wiring/Electrical :: 1995 F150 - Chirp And Shudder At Low RPMs / Squeal And Vibrate At Higher RPMs
Ok, I have a 95 F150 5.0. It's sat for 6 months with the engine taken apart. I just finished putting everything back together with a new alternator. Well, I pulled a bone-head move and forgot to connect the harness when I fired the truck up. Other than not charging though, it ran fine. When I connected the harness, it began to chirp and shudder at low RPMs and squeal and vibrate at higher RPMs and it over heated VERY QUICKLY.
So hot the case was too hot to touch and the pulley smoked the belt. The engine didn't even have time to get up to operating temperature. I've had the alternator replaced twice, and this last one tested good putting out 14.5 volts. The work I did on the engine was to replace the valve springs, install a direct drive timing gear, replace a spun harmonic balancer, bypass the smog pump because it froze up, new distributor, a new ECU and O2 sensor.
Golf/GTI VII :: Clanking Sound On Boost In Higher Gears
I noticed this sound on Thursday, I couldn't replicate the issue at first, but it's getting worse. I can now replicate it almost any time I get into boost in a higher gear (4th, 5th mainly). Partial throttle, usually starts around 3,000 RPMs. Can't quite tell where it's coming from, but it's a bit concerning. I've got 16,000 miles on it with no mods (DSG gti). It'll be going to the dealer next week for sure, but what it could be? Kind of afraid to be driving it, but my dealer is closed until Monday and I wont be able to get over there until the afternoon.
Sound starts at about 6 seconds into the video (it's quiet, but you can hear it well if your volume is up), turbo starts spooling up at about 4 seconds. The car has a slight hesitation when the noise happens, but it's not violent. No CEL.
Passat (B6) :: Higher Pitch Of Faster Turning Engine / Car Idling At Higher RPM At Stop
Sometimes I will stop at a light and my idling rpm will go from 600 (usual rate she idles at) to about 950. While this may seem inconsequential in the grand scheme of things, it's noticeable enough that it seems like the car wants to go. It'll lead me to depress the brake more. You can also hear the higher pitch of the faster turning engine (it is a 50% increase in speed). This will happen at random times so I have not been able to pinpoint if it is caused by a particular driving style. ECM for this?

My Turbo Passat has slowly been loosing its A/C Power. Im thinking maybe a recharge will work. Is this complicated to do? I know they sell the cans to do it yourself just want to double check with the VW people to see if there is anything I need to look for while doing this.

Golf V R32 :: Exhaust Or Vacuum Leak At Higher RPMs
Recently bought a MKV R32. Already had a magnaflow cbe, k&n panel filter, and some emissions stuff taken out from under the hood. not sure if it has been flashed, waiting to get a vagcom. think it is pretty stock other than that. My problem is about 2 weeks after I got it, I started to notice an exhaust leak or vacuum leak or both at higher RPMs, like above 3 or 4k it starts. The exhaust has a nice deep rumble in normal driving but when the leak noises start that is all you hear, the exhaust note disappears completely. I have tightened the clamps on the cbe and still does it. Not sure what to look for.

Experienced a ticking noise when at WOT with the 4.2 V8 engine? When cruising around the engine sounds fine, but when floored the engine (i believe) is ticking at higher rpms. Hard to believe its the engine, only 24k miles on it, with regularly changed oil. Sounds like either detonation or valve interference.
View 10 RepliesGolf IV / Jetta IV :: Overheating Mainly On Freeway While Having Higher RPMs
I have a 2004 Jetta 1.8t. 160k miles. Bought it recently. It's been overheating on me. Mainly on the freeway while having the RPMs higher than the small streets. I don't see any leaks. I'm not losing any coolant. But I do smell burning coolant. I don't see anything smoking though. I changed out the coolant temp sensor. I have a thermostat but haven't gotten to it yet. Just wanted other opinions before moving on. There is some sort of little motor on the radiator with some coolant hose connected to it. When turning off the car, it stays on and buzzes for a good 10-15 minutes before stopping. I'm not sure if that has anything to do with it. I don't even know what that thing is or called.

View 3 RepliesGolf/GTI VI :: Power Boost Very Weak When In Low RPMs
So I installed a new f23 turbo about a month ago now. Doug over at frankenturbo has been working with me to tune my car, but we have figured there is a possible boost leak. I've checked all my hoses and can not find any bad connections. My current setup is a forge twintercooler, cts intake, and a ecs boost gauge. I've been over everything 3 times now and can not see where anything could be leaking. I can tell you when in low rpm's the power and boost is very weak. Doug suggested to turn the wastegate up and we did. Still no result for the low rpm to build boost. I'm at a loss.
View 7 RepliesPassat (B7) :: Loosing Coolant But No Visible Leak?
I started loosing a bunch of coolant on my tdi which is still under 36k and there is no visible leaks anywhere
Took the car to the dealer last night to get it checked out and they were ready to send me back home telling me there is no issue since they don't see any leaks under the car
Either way after telling them that I have already gone through 2 gallons of coolant they decided to top off the coolant and ask me to drive 200 miles.
I drove 156 miles last night since I need to get this issue resolved and now the coolant tank is empty again... sitting at the dealer while I'm typing this.
Cherokee :: Compressor Shuts Off While Driving - AC Cuts Out At Higher RPMs
I got a 99 jeep sport straight 6. AC works fine after topping off. Pressure 32 l/s 210 h/s could still be a little low but air is very cold. Problem is while drive compressor shuts off. I thought it may have been too low causing it to kick off. while in park & holding rpm's at 2k everything seem to be ok.
It cycled on/off at times as normal but then compressor stopped & didn't come on again. shut the engine off checked the fuses restarted & the air is back running like normal?? so whats going on do I have a bad l/pressure switch or may be a relay sticking??while at 2k rpm's l/side 25 h/side 250 then at idle 32 & 210. I don't think its low enough to cause the shut off but.....
