I installed a Unitronic intake last summer and I get this really weird rev hang when coming to a stop. When coasting to a stop the rpms fall at the regular pace until about 1100 rpms then they hold there for a second before returning to the normal idle, It also happens while revving in neutral occasionally.
View 1 RepliesJust installed a revised VWR intake on an APR Stage I car. Haven't updated the file yet to account for the new intake, and at about 4400 RPM at WOT, the car hesitates.
View 2 RepliesI am the original owner of a 1993 Nissan Altima. My mechanic states that the air intake (part # 165751E400 "air duct")has dry rotted. He put some silicone hoping that would seal it but it did not work. The part is no longer available from Nissan. The car runs very rough and wants to stall when coming to a stop. It also smells like gasoline in the cabin and the gas mileage is terrible 17 mpg. I have tried to find someone who could custom make a new hose with no luck. My mechanic stated that pulling one from a used car would have the same problem. What other options are available? The hose is about 8 inches long and about 3-4 inches diameter. It has other small hoses that attached to it. Do I throw away an otherwise reliable car?
View 4 RepliesMy brake pedal started to vibrate after I installed my intake. I put the stock intake back on but it still does it.
View 7 RepliesI installed my sway on saturday and it went smoothly. The bushings were greased up, bolts were torqued to spec, nothing was rubbing or touching in anyway. Now I am getting a knocked noise coming from the rear passenger side. after driving it for a day or so i check under the car to make sure nothing loosened up and everything was just how it was when i installed it. What the issue could be, but the noise is really annoying.
View 4 RepliesI have a small clicking sound coming from my intake manifold. I recently installed a boost gauge and it did it once after that... I shut the car off and I didn't hear again until 1000 miles later and its back, why it would be clicking like this but its annoying
View 6 RepliesPut in my new S&B intake today and when I stomp on the gas I am getting a loud shuddering noise from the intake when I change gears. Also sounds like a squealing sound sometimes. Doesn't sound like other trucks that I have heard. What that could be?
View 14 RepliesI have a 01 vr6 mk4 gti. When I bought the car I noticed a rattle but never paid mind to it. But now I just want it fixed. I hear the rattle come from the back of the engine near the intake manifold when I rev it a little. The most rpms the louder the rattle . I been doing some research and came to a conclusion that it could be the shift rod and bad intake bushing. But, I'll like a link on how to replace the shift rod.
View 5 RepliesSo I installed my intake....again this weekend and have been monitoring it to make sure it doesn't pop off again. When you first start up, there is a very loud growl coming from the intake that lasts about 20 seconds. I also noticed that the breather filter kicks in during this time as well. Is this normal? I would yes but want to understand exactly why...
View 12 RepliesOK, I admit I'm driving a new 2016 GTI, but I still have the trusty 1.8T. Fixing some stuff so my daughter can take it over and bring to college.
I replaced both clutch switches, turns out the 1 that prevents the car from starting unless the clutch was pushed in had failed (the spring broke). Since she is new manual tranny driver, wanted to fix this.
Now I've noticed the engine revs hang or increase a bit during shifting. Hmmmm, never observed this in 16 years with the car, and don't think it did it before replacing switches (but not 100% sure), so, I cleaned the throttle body and the sensor in the manifold. as suggested Re-installed and did throttle body alignment with my Ross Tech.
Car definitely idles better and rev hang is not as bad. Good, but not quite right. So, I've read it is supposed to do this, but others say no it isn't not sure. Is this normal or do I need to chase other things?
Went to have 2007 Rabbit "flashed" tp get rid the rev hang problem. Shop said they do this all the time,but for some reason my ECU is locked and they cant get into it. What was going on. Strictly stock. What is going on?
View 1 RepliesIt makes a weird 'fppp' air shooting noise before the exhaust note and my 2003 gti vr6 makes the exact same noise. It sounds like it's coming from the intake manifold valve and not really the filter, but I'm not sure and yes my filter is clean, the noise also sounds a little bit more obnoxious and problematic in real life. What it is, I thought it was a vacuum leak but I don't wanna bring it in till i know exactly what it is,
View 2 RepliesI don't know what's going on with my power windows control on the driver door. Auto up/down function is not working. It cannot roll passenger windows up or down. I checked the other 3 doors and the switches worked. I don't know where to look!
View 8 Replies've had my R since last July and I love it so far (20,000 mi.). Recently I have run into a couple of problems.
1. When coming to a stop, my RPM drops to 600 and then as I release my foot off the brake, it dips down to 400 and back up again causing a "jerking" motion. This sounds a bit different then what most of you are talking about regarding the recall.
2. I am about to buy my 2nd new front tire due to a bubble in the sidewall. I have the Dunlop SP Sports.
I picked up a mkIV about 2 weeks ago, I've noticed that when the car is warming up that it feels like the transmission makes a *thunk* when coming to a stop. It seems to go away for the most part once warmed up, but every once in a while it will happen randomly after the car is warmed up though. I'm assuming this is the transmission disengaging as the wheels stop turning. Is this something I should be worried about, or is this "normal"...
View 4 RepliesWhen I come to a stop there is a squeaking sound that is difficult to localize. It sounds like a combination of a squeaky rubber bushing and/or squeaky bed springs. The volume is magnified when slowing to a stop in a quiet garage but the best I can do is localize it to "the underside of the car".
View 15 RepliesLast Thursday I was coming home from work and the first time I came to a stop the R32 began to buck just as I gave it a little gas. Tried stopping and starting it but it continued to do it the rest of the trip home. Fast forward to this morning (first time we've driven it since) and it completely stalled on my wife on her way to work. She managed to get it started and get it home. I drove it around the block and sure enough when it comes to a stop after moving it stalls. I was able to consistently get it to stall just by getting it moving and then coming to a stop. I scanned it for codes last night and got a couple of different codes. Ignore the photo-sensor one - I am fixing that just need to find what I did with it.
Note the address 17 stuff - 2 codes to do with failure of the fuel sending unit. Could this possibly cause the car to stall out?
Also, address 16 (steering wheel) - RossTech seems to think these codes mean a faulty ignition switch.
I've never done data logging before but I was able to capture one of the stalls with VCDS. What columns would be useful to see and troubleshoot?
Here's the link to the log
01-Engine -- Status: OK 0000
02-Auto Trans -- Status: OK 0000
03-ABS Brakes -- Status: OK 0000
04-Steering Angle -- Status: OK 0000
08-Auto HVAC -- Status: Malfunction 0010

So I have the warranty on my car still and I've brought my R into the dealership to have it checked out. They want to do more "diagnostic" work on it since they're not sure what's wrong with it.
The Issue: When coming to a stop, the RPMS will occasionally surge up to 1500ish RPMS, before slowly dropping down to the idle 800ish.
CEL has come on twice in the past month after a day or so of this happening (first time, CEL went away on it's own after 3-4 days, 2nd time, I had the code cleared at the dealership).
Code: P0507 - Idle Air Control RPM Higher Than Expected
I'm thinking it's the PCV valve failing, or in the process of it. The dealership says they think it's an air leak somewhere in the intake system...which would make sense to me if it was a static, constant problem, but it's not. Therefore, through deductive reasoning, I believe it to be a moving part or a valve or some sort that is failing to operate properly.
The car is 100% stock. I have to take it back into the dealership in a couple of days, and I would like to suggest they check the PCV valve if that is the general consensus on here rather than waste more time.
Coming home from a 2500km round road trip and back. At the time I was about half way home during the 1300km day, the car is in D and has been all day and it has been about 500km since I last came to a complete stop. I stop at a red light on the highway in a small town on my way through, look at the tach and see the rpms, once its dropped down to first, dip down to about 300 or so, then quickly back up to 550/600 which is its normal idle, then all the sudden it stalls out completely killing the motor. Cycle the key and start it up right away and it drives as usual. his might be the 2nd time this has happened. R32's and DSG.
View 9 RepliesI have had my golf R for 7 months now and ever sense I got tuned I have had this little issue. Besides this the car is amazing but ever now and then the car while coming to a stop and put it in natural to come to a stop the idle will go to 500 then come back up to 1200 then rest at 800. I'm getting my PCV replaced tomorrow. I'm um stage 2 tune fully loaded with Bsh intake full 3" exhaust.
View 4 RepliesI picked up an '08 R32 about two months ago and was having issues with the DSG and the dealership determined it was an issue with the mechatronic unit so they swapped it. That made a huge difference, but the downshifting is still very hard when coming to a slow stop (to the point where the car jumps), especially from 2nd to 1st gear. About half the time when I back out of a parking spot, then put the car in drive and start to give it gas, the car doesn't move for a few seconds as the RPM's build, then it slams into gear.
This all happens in drive (D). I haven't even used the other modes to know if it's happening there too. The dealership says they don't see any issues with it and there are no error codes and that there is nothing wrong with the car, but this is by far the worst transmission I've ever had in any car I've ever owned. I find it hard to believe that VW and Audi would put this in their higher end cars, so I can only assume there is something wrong with mine.
