Passat (B6) :: Sudden Boost Loss At 4000 RPMs
Jul 13, 2011
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).

At 30,000 and change I had new tires and they did RVU 17D1/07 Crankcase Breather Valve Replacement recall. Ever since then I have notice a decrease in my MPG.
I was getting around 32 MPG (mostly Highway driving) or about 540 miles on a tank. Now I think i am LUCKY to get 28 or about 480.
Could it be the tires? Or is it something with this recall. I went from the Stock Michenlins to Cooper CS4 Touring. I just think 4 MPG would be alot from a tire change.

I have VW99 Passat 1.8L Turbo, automatic with 170K on it.
My car shop changed engine oil yesterday with 4 QTS of Mobile 5W40. Now, when I check my dipstick today, on level surface, the oil level is way too high on dipstick kink [the cross-hatched mark]. I run the engine, shut it off, and let it set for 3 min, but still the level is too high above the Mark. It wets the dipstick almost till the top of its Head.It was reading High when I first checked it, this morning, before starting my car.
It seems the oil is 'overfilled' or showing over filled; and the engine is about to throw it out from "filler cap" where Dipstick goes in the engine. I saw him using 4 cans 1 QTS oil, which I bought, into my car. They did change the "oil filter" at the same time?
Now, my car looses power while driving. When I accelerated from a stop/light, car slows down or limps. The car suffered a sudden loss of power.It runs awful for about a mile but smoothed out after acceleration.It feels like the car is running out of gas for a few seconds, then all of a sudden it kicks in. The car still drives ok though - No error messages/warnings on dash,CEL, no smoke, no hissing. I actually don't see engine oil thrown out or leaking though.
I don't know if the shop drained the "intercooler" while changing the oil, also I know nothing about its importance to my power loss issue. The net search manual/states "The engine oil, above the level, can be drawn into the crankcase ventilation system, and enter the atmosphere via the exhaust system". But it does says about damaging the engine/car.
Should I be worried about the damage to the engine?

On Sunday my son was driving my wife's '03 Passat GLX 2.8 4motion station wagon when he received a "stop engine" warning and noted the temp was climbing past 250. Good lad that he is he stopped immediately and noted much steam and coolant originating at the rear of the engine. My hope is that it's just a hose since there is no coolant or smell in the interior (just went through the nightmare of a heater core on my '96 Jetta!) We had it flatbedded to our home but I haven't had time to make a further investigation and was hoping for some insight from those here as to how I should proceed in diagnosing/repairing this issue.

I have passat 2007 2.0T , about 98000km. A few months ago, my vehicle randomly has hiccup with EPC light when I put on the pedal. Each times i put on the pedal my vehicle hiccups and EPC light on and all goes away when i put off my foot from the pedal. It happened randomly, so i went to vw dealership twice. They keep saying they could not find any problem. Coz as i said it happens randomly. I paid diagnostic fee but still the problem remains.
Unfortunately today i had the same issue hiccup like crazy with epc and engine lights. Also on the highway my baby 2 years old was with me when i drove, my vehicle lost power all the sudden, all most i involved an accident with following vehicle. I started the engine, vehicle moves but with the problem. I feel wheels do not spin properly or transmission randomly. What the problem is?

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.

so there is no visible signs of a boost leak and my boost gauge shows normal vacuum at idle indicating its not a vacuum leak, yet in the higher rpms im loosing boost.

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.

So i have a 2010 gti stage 2 uni, when i have a half tank of gas or less when it reaches about 4000rpm it will loose power harshly that it almost makes u eat the steering wheel, but when it has more than half a tank of gas it drives just fine. I get low pressure fuel rail code when scaned with vagcom...

2006 Kia Sorento Auto Transmission, Appx. 106k miles. My wife's car so I don't drive this very often. However, on the last trip, I noticed that it would stay in a particular gear longer than (I think) it should. The RPM's will go up to maybe 4000 or so and stay there for a while even if I let my foot off the gas before finally kicking into overdrive or the next gear and back to a comfortable cruise. I notice this mostly happened when I was going highway speeds and either passing someone or going up a hill. I can't think of the last time the transmission fluid was changed, so I'm thinking that may not be a bad place to start...

So I drive a 2008 R32/U.S. spec and I was in neutral when I pressed the throttle and it would not rev over 4000 rpms and was wondering why??

I have a '96 Saturn SL with a 1.9 SOHC. I recently removed the engine and transmission to change the clutch. I also changed the timing chain guides, the valve cover gasket, the timing chain gasket, oil pan gasket, front and rear crank seals and motor mounts. After I put it back in, it revs to 3500-4000 rpms and is very rich (so rich it smokes). I replaced the throttle position sensor since it had a crack at the plug and to see if that was the problem. I have looked at everything again and nothing is jumping out at me.

I have a 2006 chevy malibu 2.2 ecotec 4 cyl with ~130,000 miles and i am experiencing the following symptoms:
Car will not rev past 4000 RPMs or go over 70mph. I do have a check engine light with the following two codes: P0068(throttle position) and P0420(cat efficiency)
My question is instead of just replacing the cat where can i take my car (i live in tulsa, ok) to have the cat and the sensors checked before they are written off as bad?

I've had a weird problem pop up within the past few weeks. My engine seems to have a noticeable whine above 4000 RPMs. It sounds almost like a supercharger whine, but my engine is completely stock. Possible problems I found online include exhaust leak, vacuum leak or tensioner issue for the belts.
Another issue I have had is that whenever shifting into second gear, I have some difficulty getting it into second gear. It makes a scraping sound as though the clutch is not disengaged all the way. On occasion, I have also had the shifter kind of pop second gear out when continuing onto third or even feel like it is rejecting second gear sometimes. A friend of mine told me that the scraping sound is normal and, "that's just how manuals are." Doesn't seem normal to me especially since it is every time I shift to second gear.

I am hearing a rumbling noise when I hit 4000 rpms on all gears worst in 2nd and 3rd.... I just recently replaced the timing belt, TBA Done, valve cover gasket, and passenger side axle (through raxles). Anyways I started hearing noise after those repairs, my mechanic has gone through all the work recently done and cant find the problem..... We replaced the tranny mount thinking it was that, but no luck.... I have not lost boost, and noise starts 4000k and goes away at 4700k No codes are flashing.

Is this normal for the Camry? When you're flooring the car besides the typical roar I hear like a small high pitch noise, it's gone once I let go of the gas. I tested it & start to hear it at about 4000RPMs I believe. Recorded it on video but you can't hear it at all on video.

I have a 1990 Lincoln Mark VII, black on black, basically one owner, excellent condition... except one problem. While driving the car my speed dropped to 40mph, while my RPMs rose to 4000. Upon checking I found the plastic clip, which holds the linkage from the transmission to the accelerator had snapped. I replaced the part and still have the same problem...is my transmission smoked or is there an adjustment?

My VR6 is making a ticking sound when i accelerate, between 2800-3100, then it dies down a little and then gets loudest at about 3600-4000. The noise stops at exactly 4000rpms every time. Here is a sound clip of what the noise sounds like... you can hear it best in the last 15 seconds or so in the video. Maybe its the timing chains...

My hybrid has been a great car, owned 3 years. Now have problem: runs great but if going higher speed 65 and pulls hill needing to kick in to 4000rpms it dies right away says high temp engine but does not smell hot or need water. Let it sit for 15 minutes (even though will start right away but might keep dying unless sits). Will run fine unless hits higher rpms then dies again. 2005 Ford Escape Hybrid...

I've got a misfire problem with my Focus. It started about a month ago and did not trip a code until last week. It stumbles on acceleration between 2,000 and 4,000 rpms. It is only a slight stumble and although noticeable, it does not impede driveability much. Last week I was able to get it to finally trip an OBD code. P302 - Cylinder 2 misfire. I changed the plugs and wires with no effect. I thought I had it narrowed down to the coil or injector until my wife noticed a new wrinkle.
Under normal driving conditions the misfire is annoying, but my wife found that if she turns on the A/C, it is undriveable and will not accelerate past 30 mph without some patience and a neck brace for the bucking. My first thought was the A/C compressor was freezing up. I turned off the A/C and left the blower on and it would not stop missing. I turn off the blower and it smooths right out to the annoyance I described first.
Right now I drive the car without A/C and blower whenever I accelerate. If I'm going a steady speed, all is well and I can run the blower and A/C.

Two days ago, I was driving on a North GA steep, windy, mountain road in my 2002 v6 4.0 Ranger. All of a sudden, i started revving real high (about 4000rpms) and getting no power (20mph). I pulled over immediately and transmission fluid was pouring, by the quart, out of my truck. I didnt get to look exactly where it was coming from, since i backed away once i saw a small flame coming from the leak. i then called a tow truck (assuming it was a seal or a hose break) and had it towed to my house.
I started investigating the possible problems and didn't really see anything noticeable under the truck (not that I was expecting to). So what I did was put three quarts of transmission fluid in the dipstick hole and put in gear to see if I could spot a leak. nothing. then I drove it around the block to get it warmed up and put a little pressure on the transmission by driving up a semi-steep hill to see if that would spark the leak again. still no sign of the a leak.
And finally, when I went to go check the dipstick after my test drive, it read to be above the cross hatched area, hence being overfull. What my next step should be?
