Golf/GTI VII :: Loss Of Power Especially After 2nd Gear
Jan 14, 2015
About 3 weeks ago I purchased my MK7 GTI SE w/ DSG. About a week ago, I started noticing a very slight rasp around 3.5k and up under heavy WOT. Note the sound was very subtle in the cabin and unsure what it sounded like outside. This past weekend, I started noticing a loss in power, especially after 2nd gear. A strange sound under throttle--almost sounds like a supercharger winding down (hollow with a slight whine)--when giving a good bit of gas around 2.5k and up occurs. At first I though it was road noise from my neighborhoods new roads since the sound only occurs on new roads, but realized that noise never occurred the first few weeks I had the car. No CEL.
I took it to the dealership on a rainy day, so they couldn't see the loss of power with the car breaking loose, but they didn't find anything. I'm bringing it back this Friday to see what they can find. I talked with one of the service guys today and they think it may be a drivetrain problem. Supposedly no loose hoses and is holding boost normally. Any leads to what it may be??

Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.
I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.
There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.

I have a 2002 VW jetta 1.8t recently I've noticed that in 5th gear around 35-45 mph its losing acceleration. its a tiptronic so i can just downshift speed up a bit an o to 5th, however I don't want that to be the permanent fix, what this is or why its doing it?

I have a 2003 S-10 standard and a similar conditions as this discussion, but my issue is not with the engine bogging down. The engine RPMs increase, but the truck does not pick up speed until I let the engine settle, then push the gas again. If I drive too long the truck will start doing this in 3rd and not just when I shift gears. It's like the power is just not making it to the wheels. There's a disconnect in the power transfer or something.
The clutch (clutch kit), flywheel, master and slave cylinders, and the lines to the cylinders have all been replaced; some twice. I just had the transmission and differential fluids replaced. Is this a transmission issue or could this still be something to do with the clutch? Or is it something else entirely?

I had idle travelling problem wich I solved changing AIT sensor. At the same time I cleaned MAF and TB with air sensor cleaner. Now my problem is cold start and driving 2nd and 3rd gear. Instantaneuous fuel consumption will go 20l to 50l driving 2nd and 3rd gear and if I stop values lowers like 20l...16l...10l... and finally on idle it stays in 0.8l/s. Average consumpion has increased 1l to 2l/100km.
These are the air mass readings when I drive 2nd and 3rd gear

I recently (July 2016) bought a 2012 2.0T Limited with 14K miles. Got an awesome deal on it and really love the car. About two months ago the car had a total loss of power/boost. I took it into the dealer and they performed a wastegate actuator adjustment (something I will be doing on my own now if it becomes a problem again). Now at about 21k miles I'm having a different issue. Here is what's happening:
Accelerating from a stop the car feels as if it's falling out of gear intermittently. Once it happens and I press the gas more/floor it, the car doesn't respond. If I let off the gas and then press it again, the car will then start to accelerate again. On the highway cruising at 70ish, the same thing happens and it even oscillates with constant throttle like its down/up shifting. The ESC light came after a 20 mile highway trip of this oscillation. No CEL. When I got off the freeway, the navigation screen said there may be a problem and I should press the bluelink button.
When this is happening the cruise control either doesn't work at all or the "cruise" light will come on but I can't set a speed. Tonight I noticed in the rear view mirror that the brake light stays on or even flutters after I brake which corresponds to when the cruise is or isnt working as well as when the car intermittently falls out of gear/oscillates falling out of gear with constant throttle. If I notice the brake light is on without actually braking, I can take my foot and pull the brake pedal towards me which turns off the brake light and then the car seems to work correctly as well as the cruise control. The car is driveable but definitely something is wrong.
I should mention that I checked the voltage for the wastegate actuator and it is 3.97v which I believe is within tolerance. All of these issues with no CEL.

I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

My 95 civic lossed all power slowly while doin 70mph on the freeway in 5th gear and wouldn't accelerate no matter how much gas i gave it. My battery lihht came on at the same time. I just put a new engine, transmission, distributor, engine mounts. Where I should start looking for a problem first.

When passing or going up small inclines on freeway, my F250 seems to make the shift to the passing gear but then almost a complete loss of power. Jerks around for a few seconds and finally provides enough power to at least get back to the original speed. (It feels kind of like the lurching, etc. I used to get when those stinking GM diesel injectors would act up in the 1990's.)
It also stays in first/second as I punch it while entering the freeway and doesn't want to make the shift. I can put it in neutral and race the engine, so I don't think it is an engine problem, unless the transmission is electronically controlled. I have a lot of computer dashboard gauge resets after falling to zero and sometimes have to set and release the parking brake to get the auto door locks and windows to work. (That started after a car break in where the door electronics were apparently pinched, but that was a couple of years ago.)
Does it sound like the transmission or electronics? In the old days replacing an automatic transmission filter seemed to fix a lot of transmission issues. Not an option now, but would I expect to see any results doing a transmission flush and fluid change? It's probably been about 60000 since I had that done. (157000 now).

The car has 108k I bought it with 101k that being said I had no clue when the last tune up was or if the coils were replaced, now I did replace the transmission, transfer case and clutch since then I've noticed a loss of power and torque especially after 3-4k rpm car just seems to fall on its face, if I had to explain it I would say it feels like it went from being tuned to stock, I have no clue if the car had software or not. also some times I get a sputter or almost a hesitation from the rear, I have done the haldex service 2 weeks ago, It absolutely feels like the car isn't breathing right I don't hear the intake as much or cleanly I'm wondering if the intake manifold bushings are bad and could even cause this? doesn't seem to pull as much just from the start though I used to just drive normal and the car almost felt like it was pulling its self doesn't feel anywhere as quick.

So I know turbos can be prone to heatsoak. Does the same type of deal apply to SCs?
I guess my question is; when on the track, the SC obviously gets hotter than hell. Subsequently, do you lose power due to the SC possibly "overheating"?

I seem to loose almost all power once I hit 5k rpms. Like I will floor the car and Ill feel a nice pull and all of a sudden once I hit 5k it slowly starts climing like a hybrid civic. wtf? Could this be a misfire, tune problem, exhaust leak IDK

I just had my '12 GTI's 40,000 mile service done about 2 weeks ago. I put in a K&N air filter the day after the service. The only thing I noticed about the car after service was that I could smell coolant, they either spilled some or its burping some cause it was filled past the max fill line. Outside of that everything was copacetic until yesterday morning.
On my way to the gym with cruise control on ~74 mph on the highway I had sudden power loss, EPC light came on and power returned although felt reduced. When I left the gym it was off and I made it about a mile when under acceleration it hit at about 3k rpm, again sudden power loss and EPC light, power returned reduced. Drove about 5 miles to work and did a little googling with a million results.
When I left work to go home I made it about ten minutes into my drive before it happened. This time the CEL came on. I was able to drive home and back to work again this morning but I keep having power shutters followed by the EPC. I haven't had much time to dig into anything but I checked the connection of the coils and the intake connections with a flashlight at 4:30 this morning. Thinking it might be the MAF only because I recently installed the K&N and have read the oil can kill MAF's and I might stop to get a can of cleaner on my way home to try that route.
IF that doesn't work maybe I can get it on a Vag Com in the next couple days to get it sorted out.

Replaced my cam follower at 37,000 mi and performed an oil change. Follower was in good shape - all done at a local reputable tuning shop. Accelerating on the highway, above say 2500 rpm, loss in power.
Car feels dull under load. Called dealer for advice (I'm tight with the owner, the tuning shop was closed at this point) and said that I might have a fuel pump or cam shaft problem. Car was fine before service.
What it could be? Will obviously call the tuning shop on Monday, but wanted to vortex advice so I could be armed and ready!!!

Today i come here for a AC/Compressor trouble: The AC on my Jetta 2000 2.0 works very well, however it seems that the engine loses a lot of power when the AC is on (the acceleration becomes very slow), and at the moment of turn on the compressor, the engine revolutions down to 400 rpm for a couple of seconds (after back to normality, 800rpm on idle).
I know that the power loss on engine is "normal" with the AC, but in mi case, seems excessive, and the fuel consumption, when the AC is on is vey high too. I think that maybe the compressor is stuck, but I'm not sure about that.
As additional information, i scanned the engine codes an throws P0422 (related to oxygen sensor)

I bought a 2000 jetta gls vr6 5-speed. Only had the car about 4 weeks, already I am in, ball joints, struts, brakes, core leaks and my half shaft fell off at the transmission. Now, driveabilty issue.
Severe loss of power, sputtering bad. when i shift, the car revs a bit. installed new O2 sensor due to a rich code and a out of range code. Now the EPC light is on with an implausible brake switch signal. Replaced switch still comes back on. Still running like poop. Changed the plugs also about 1k back. I just ordered a MAF.

I have a 04.5 GLI 1.8t, performance mods include, cone filter on the end of my maf, silicone TIP, Forge splitter, 3in custom tbe and unitronics stage 2
I started noticing this problem on the day I got the car tuned, I hadn't noticed it before hand. I replaced the spark plugs and it worked a little, but it continues to do it.
The problem: When I get on it at WOT under full boost, around 2500 rpms, the car loses all torque, misfires spits and sputters throughout the rpm range until about 5300 rpms then it all of a sudden has torque and pulls great.
I don't have any boost leaks that I know of along with vaccum leaks. There is no flashing cel or misfire code for my coil packs. Can this be a faulty n75 valve? if so what could fix it?

Due to being low, and taking my splash guards off to put on my skid plate, in heavy rain, my belt I guess gets wet, slips and I lose power steering. I can hear it screech.
I didn't think that would be the case for snow, but sure enough after plowing through my driveway to go to work it was slipping screeching and loss of power.

My car has been throwing a code P2178
P2187 System Too Lean at Idle (Bank 1) DTC.
Checked the intake, checked maf, checked injectors.
Today after leaving show n go. Stopped at a gas station (never turned off the car) leaving the gas station the car was loosing power, I thought I was in 3rd instead of first. No, I was in 1st. Driving and car was sputtering and wasn't getting any power. After a few blocks it sounded like its gonna shut off. Pulled over to the side. Car died, doesn't wanna start again. Got spark, got fuel to the injectors, discoed the sensor to maf, still cranks but doesn't start. Got it towed to NY from NJ. Still no start. Few people said crankshaft sensor, starter, clogged cat or fuel filter. Car isn't throwing any codes now (probably cuz the motor didn't start) any clues on what it can be?

I drove my car to work today and no problems. Tonight my wife and I took the car out to go to dinner and intermitantly there and back my car is hesitating as we drive along. I thought it was odd at first then my wife asked if I was kidding around. I told her its not me.
It's as if the car is driving then all of a sudden its like a loss of power or as if the limiter kicks in and starved the engine of gas and then a second later it jerks back to life and keeps going.
If it does this tomorrow its going to the dealer. It is not throwing any warning lights and I have 3/4 tank of gas so its not that.

Earlier this evening on the highway while in cruise control I had a strange issue. Going up a slight incline all of the sudden I lost power, my ESP and EPC lights came on, and the engine was running very strange.
It wasn't stuttering but was louder and vibrating a whole lot more than normal. I pulled over and shut the car off for a couple mins, started it up, everything was normal and continued. About an hour later the same thing happened and when I started up the car again the check engine light was on.
I had my room mate scan it when I got back and it came up with ECM and PCM processor errors. Not sure what kind of problems this would be. All the searches on cruise control didn't turn up anything like this. What the problem would be? The cars a turbo'd r32.
