Golf/GTI VI :: Losing Boost Above 3500 Rpm?
car is losing boost as soon as it goes above the 3500 range.
it will reach peak boost at WOT but begin to tamper off as it goes higher in the range and will reach as low as 5lbs towards 5-6k
i have an apr stage 2+ tune and my peak boost is usually 17-19 lbs.
check all hoses and everything checks out fine.
Golf/GTI VI :: Fluttering Noise At Boost Between 3500 And 5000 RPM?
I have a 2011 GTI, with an apr chip and apr intake stage 1. Car is brand new 4000 miles
When hitting boost in 3rd-6th gear i hear a fluttering sound between 3500rpm and 5000rpm after 5000rpm the sound either dissipates or is drowned out by the motor.
I've done a lot of research around this sound and i havent been able to find a certain answer, it could be compression surge (i wouldn't see why), a leaky DV ( also cant see why because the 2011 has the new revision D piston actuated DV), A fluttering wastegate.
Sage 1 apr chip and stage 1 apr intake...
Golf IV R32 :: Mild Knocking Sound Whenever Go Over A Bump
So I changed my fuel filter a while back and I've been noticing a very mild knocking sound whenever I go over a bump. I didn't have access to a lift when I was doing this, so I attempted it with the car on the ground (worst idea ever - there wasn't enough ground clearance for me to even fit my head under there...). Everything is hooked back up as I thought it was originally (car runs fine), but now that I think about it I'm wondering if there's a bracket above the filter that should be secured within the hose clamp, along with the filter & the plastic piece that attaches to the filter. And if so, any tricks as to how I can secure the hose clamp to the bracket without having to remove the filter all over again? I had no way of telling whether or not there was a bracket... I could hardly see as it was and was more concerned about not damaging the fuel line clips.

Just bought a 2015 golf TSI 4-door. First time VW buyer so Im not sure if these are normal or I should bring the car in to get checked.... At a dead stop when I accelerate the car seems to shake a little (until 2nd gear kicks in) then it stops shaking, Also, When Im in traffic and I go from dead stop to accelerate to slow down again, it feels like it is down shifting very hard.

2012 gti, completely stock, 21,000 miles. Perfectly smooth ride right up to 69mph, then mild/moderate vibration in the steering wheel at 70+mph... figured it was an out of balance wheel up front, had the tires rotated, but still vibrates. I suppose ALL the wheels could be out of balance, but seems unlikely?? Will have the balance checked on all wheels...

When I drove the car on Monday a hesitation/jerking randomly came out of no where during mild acceleration at around 2500 RPM. The next day it was doing the same thing, but one of the times it made the check engine light flash a couple times then go off. On Wednesday I put fuel injector cleaner and a new tank of gas in it to see if that worked at all, but it didn't. The problem was still occurring then the engine light came on and stayed on. So I went to see what the problem was on VCDS and here are the errors that came up. Also I should mention that on Tuesday my battery died and I had to get a jump from someone, this didn't affect the problems, but I think it has something to do with the voltage errors.
A Summary of the errors is lots of things about "low voltage b+" and "engine misfires".

Golf IV / Jetta IV :: Motor Ticking Around 2500 - 3500 Rpm
My 1.8t motor is still ticking around 2500-3500rpm. I have changed the oil with 5w-40 mobil1 no even 75 miles on oil change, Brand new oil pump with tensioner and chain. oil pick up tube cleaned and good. new plugs about 75 miles on them as well. Always ran 93 octane (highest I can get at my gas station) Only thing left that I can think of is my cam tensioner is bad.
When I accelerate up to speed it starts ticking but as soon as I let off the throttle it will stop get back on the gas it starts again.
Stockish 2000 gti 1.8t 5 speed. short ram intake.
Is there a way to tell if the cam tensioner is bad? .
Golf IV / Jetta IV :: Vibration When Engine At 3500 RPM (in Any Gear)
I lamented in the past a lot of vibrations when the engine was at 3500RPM (in any gear). I read on the forums and many people blamed the aftermarket "EMPI" axles that I mounted too. In fact, my OEM outer CV joints where seized inside the hub/spindle and one of the inner CV joints was clicking; the boots were all worn. This was the reason I went with aftermarket axles. Anyway, I rebuilt the OEM axles by keeping the shaft only, and getting good quality inner and outer CV joints. I finished today to swap back the OEM axles and, finally, no more vibrations!

View 11 RepliesGolf/GTI VI :: Clutch Noise / Muted Sound From Engine Around 3500 RPM
So I am new to the VW TDI, and I am hearing some noises I am not used to...
First noise, when the transmission is in neutral, clutch pedal not depressed, I hear a noise from the clutch (makes the TDI sound louder than it really is), if I put the car in gear, the noise goes away (even if I put it in neutral and keep the pedal pressed in), sounds like the pressure plate or clutch could be making that noise, is this normal or not ?
Second noise, when accelerating (especially accelerating hard) above 3500 rpm or so the engine makes a weird muted sound, I can't really describe it, maybe like bubbles of air in water would do, but muted ... it's a weird sound !
Golf VI R :: Loud Noise Between 2500 To 3500 After Installation Of Exhaust - Vibration
Recently had an aftermarket turbo back exhaust system installed. After driving for a short while, I noticed that between 2500 and 3500 RPMs the noise was very loud. Once I hit the highway (in which the engine almost exclusively hangs around those numbers), it was almost unbearable to sit in the car while having that constant droning sound. I have had and been in cars with aftermarket exhaust systems before and never heard anything quite like this. It is pretty tame below 2500 and once you hit 4000, it sounds quite nice and that horrible drone goes away. I really trust the shop that did the work, so I doubt it was faulty install. Could it be a faulty design or maybe just the one that I received?
This exhaust is from a reputable maker and they designed this system specifically for the Golf R. I did have some other mods done at the same time (Coilovers, Engine Mount Insert, Intake and a Tune). I know the insert may cause a little bit of vibration and hence a little bit of extra noise, but nothing like this. While driving on the highway at 3000 RPMs, I cannot even clearly see the cars behind me through the rear windshield as there is so much vibration from all the noise.
Forgot to mention, this TBE is resonated with a CAT, so even more reason for concern. Would expect it to be quiet by comparison to a CAT-less non-resonated system
Golf IV / Jetta IV :: Chokes The Power Past 3500 RPMs And Continue Running Rough
I own a 2001 Jetta GLX 12v VR6, lately the car has not been running well. It chokes the power past 3500 rpm's and will continue running poorly and sound sort of like a Subaru boxer engine. Sometimes it corrects itself and runs okay but goes back and forth.
I ran the codes on VAG COM:
6 faults found:
17551 - Load calculation cross check
P1143 - 35 - 10 upper limit exceeded - intermittent
16712 - Knock Sensor 1 (g61)
P0328 - 35 - 10 Signal too high - intermittent
[Code] .....
I ran VAG COM a couple of days before these codes came up and I had a different code dealing with air/fuel mixture, something about fuel running to rich. I'm stumped.
Golf/GTI VI :: Hesitating As Accelerated Past 2500 - 3500 RPMs - Ignition Coil Blown
So over the last couple of days my GTi has been hesitating as I accelerated past 2500-3500 rpms so I took it in to the dealer this morning to have them look at and sure enough, it had blown an Ignition Coil.
I know this was a common issue with the 1.8l Turbo engines but I thought this had been corrected in the new models.
I have a '10 GTi with 14000 km's on it and some mods (see signature). And no, they didn't comment or ask about the APR chip or intake.

View 9 RepliesGolf/GTI VI :: 2003 1.8t Pre-Detonation When Boost Over 9 Psi
I have a 2003 jetta 1.8 turbo with a APR chip boosting 21 psi. I have had no problems for the first 5 years or so, but then recently within the last year it started predetonating when I boost over 9 psi, I've tried replacing the injectors, upping the fuel pressure, using 93 octane fuel, (which I always had used anyways) replacing the oxygen sensor and other things to no avail. Also there are no codes regarding this issue stored in the computer.
I highly doubt there is any issues with carbon buildup in the pistons.

Golf IV / Jetta IV :: Won't Boost Past 4 Lbs?
my car into VAG COM and since then it hasn't boosted past 4 lbs. it has Revo stg 2, K04, aftermarket side mount, full exhaust and a couple other bolt ons. Before the car was spiking at around 23/24 lbs. after pressure testing the system I found that the turbo inlet pipe was lose, so I tightened it. Still no change. I tried holding the battery terminals together for 10 minutes to reset the ecu and I also tried clearing the codes through a handheld code reader. No codes even come up anyways for this. The car is a 1.8T.
