Golf VI R :: Pulse Sound When Engine Is Cold And Idle
Jun 5, 2014
I usually get this sound when the engine is completely cold. I get a weird pulsating sound that's very loud, after the engine warms up a bit. It goes away completely.

Chevrolet - Mailbu :: 2006 - Brakes Pulse Briefly After Starting Engine Cold Or Hot
2006 Chevy Malibu Maxx. This just started a little while ago, before I replaced front brake pads. after I start the engine whether cold or hot, the brakes will pulse briefly when I step on them to get the car in gear. It feels like the ABS, but it only does after a fresh start, and not when braking. The car stops fine. The brake pedal is a little spongy, probably because I didn't bleed them, but the pulse was already happening so I don't think they are connected. there are no warning lights on at all. Also, it doesn't do it 100% of the time, maybe 80 to 85%.
In order to bleed I guess I need a scan tool, but the bleeding procedure is a bi-directional function which is not supported by most of the gizmos available. Know of one that might work without spends thousands?
Golf V R32 :: Engine Rough Idle When Starting Cold
It levels off and idles fine after about 10-15 seconds but sometimes it idles so rough I think it's going to stall.

I have a 1.8t jetta that has a weird idle issue when starting and engine is cold it like to idle at 1200 rpm then will eventually work its way down to 800 rpm
I have no cel codes and have looked for vacuum leaks (but may have missed one) ,but if i start the car and it idles at 1200 rpm then i shut it down and start it right after it will idle at 800 rpm as normal.
Its a 1.8t unitronic stage 1 stock everything except e type coils with plugs at .032, Also does not have much pull after 4000 rpm, not to worried but just may be part of the issue....
Golf/GTI VI :: 2010 - Engine Shake / Vibration At Idle And Cold Start
I've had my 2010 GTI for 8 months now and have really only had one issue with it. When I start the car, it shakes before I start moving. Like, the steering wheel, body, pedals, gearshift, etc... It's not a violent shake, but definitely something I've never noticed in any other car I've owned including my MkV GTI. It doesn't seem like a normal feeling for a brand new car. I took it back to my original dealer at 4,000 miles and they said there was nothing wrong with it and they didn't feel any vibrations.
Well lately it's been vibrating more intensely and more often (at almost 8,000 miles) It now does the same thing while stopped in traffic or at lights. It's really annoying to me. I took it a couple days ago to a new dealer (I moved) and just talked to them on the phone. They also said there's nothing wrong with it and it's normal.
I forget exactly what they said it was because I was walking to the gym, but basically it was some cooling pump/fan that kicks on to cool the engine down and that's what is causing the vibration. But, they said it's normal and all VWs do it. I'm not quite sure why a fan needs to cool a perfectly cold engine in the morning though.
Golf/GTI VII :: Whistle Sound Mostly Upon Deceleration When Engine Was Cold?
[URL] ....
I have a whistle sound mostly upon decel when the engine was cold. I have the APR down pipe installed. Today it's doing it all the time even when warm. I took the car to the dealer and they said it was prolly an exhaust leak. I took the car to my friends shop and we put the car up on the lift and listened from underneath. It sounded like the turbo was echoing in the down pipe. Sometimes when it's cold it can be very loud. So my question is if this is normal with the APR down pipe or with this turbo or is this a sign that I have a turbo failure coming?
Golf/GTI VII :: Whining / Buzzing Sound From Engine Upon Cold Start Up?
This might just be car engine in general regardless of make or model, but upon a cold start, my GTI engine whines or buzzes for approximately 1 second before it stops. I had a 2009 Toyota Corolla that also did this, but I had it fixed with a TSB due to the oil not reaching the VVT-I gears or something in time. It's not the same noise in my GTI, but I was wondering about same sound almost every time upon a cold start?
View 13 RepliesGolf/GTI VI :: 2013 VW - Screeching Sound On Cold Start And Engine Acceleration
To get straight to the point: I have a 2013 GTI that has recently started making a screeching noise on cold starts and during engine acceleration (not necessarily heavy load, but actual engine speed acceleration).
I recorded a video of it this morning and it is very easy to discern the sound. The car is APR stage 1 tuned and has a south bend clutch but I don't think either of those are related to the sound. The water pump has been replaced from the service bulletin, the auxiliary belt tensioner has been replaced because it started to make a noise (this noise is completely different). Otherwise the car has never given me an issue, it has been maintained exactly per the OEM repair schedule other then oil changes every 5k miles vs. 10k. I use mobil 1 0W-40 oil.

Golf IV / Jetta IV :: 2001 - Cracked Oil Pan - Loud Ticking Sound At Idle - Engine Blown?
I own a 2001 Jetta 1.8t with Gti front end. So I was driving downtown the other day and I bottomed out really hard and cracked my oil pan. I didn't realize it was cracked and leaking so I drove it home, drove fine with no issues at all. When I got home I parked it and went inside and in the morning I came out and tuned it on for maybe ten seconds. It made a really loud ticking sound that was constant and oil pressure was almost all the way down. So I shut it off and looked and saw the oil pan. I fixed the oil pan yesterday and started it up and it sounded really good and drives fine. But I've been hearing a pretty decently loud ticking sound when everything's up to temp and warmed up. The ticking is only at an idle and it drives like it use to just sounds bad at an idle. Some people think it's my oil pump and tensioner, some people thing I ruined the turbo and possibly internals.
View 4 RepliesLexus LS 2007+ :: Actuator Noise / Pump Pulse Sound During Braking
My 2007 LS 460 makes a noise like a pump pulse sound during braking. When I step on the brake before coming to a stop there is no noise but once the car is 20 feet before coming to a complete stop at times you feel and here a pulse or pump or vale sound in the front engine area. Sometimes as I increase pressure on the break pedal a little harder you can feel and here a single pule and at times 3 or 4 valve or break pump sound. What might be going here? I am certain the sound is not coming from the wheel area. It is definitely under the hood. Could it be a faulty load sensing proportioning valve or booster?

Here is the scoop.
85,000 miles
koni coilovers
stock sway bar and bushings
oz ultraleggaras
18x8.5
Nitto invos
The other day i felt a pulse like a "wur wur wur wur" sound similar to when you throw a weight on a wheel or if the wheel is warped.
Wheels are fine. no nails no bubbles
Tires have plenty of life on them and my alignment is awesome.
The car doesn't pull, drift, nothing...
I pulled of the wheel and notice the driver side tie rod was bad.. I replaced it. Passenger side was mint. Test drove it and the car still has the pulse feel that increases in speed as I increase speed.
Here is the funny part.. there is no vibration in the steering wheel at all nor does it pull when i step on the brakes. I checked the sway bar links they are fine. Here are my thoughts.
Strut bushings?
Lower front control arm bushings?
Maybe the suspension is almost wheel hopping? After the tie rod change, I did notice it was more to the right side.. It's not effecting performance it's just annoying..
One other thing i recently took out the eip dog bone and replaced it with the stock unit that I rebuilt with new autohaus bushings I did it right so I don't think its that. Car also has steel skid plate OEM and the autotech upper strut tower brace.
Lexus ES 2007-12 :: Cold High Idle With Very Light Lifter Tick Sound
I have recently bought a 2007 ES350 that's runs fantastic considering I bought it with high miles from the Lexus dealer (149k). I live in warm climate area and I notice that even though it's not cold out in the mornings my car idles high (at about 2k) for only a few minutes 2-4 tops then starts to drop to normal as it warms up. It hurts me to hear it as I'm not use to this and I worry that it may cause damage to my engine due to oil not being circulated properly yet.
Most importantly, ONLY when cold, I hear a very light knocking sound, kinda like a bad lifter tick, but by the time I get to my daughters school which is about 5-6 miles away it goes away and sounds normal at that point. Had me very concerned as I just bought it less than a few weeks ago and I'm afraid something was wrong and dealer may been able to mask it at my point of purchase and now its starting to rear its ugly head.
This is my first Lexus ES350, not really sure if it's normal or not. I can tell you, when it warms up, I've jumped out of my car and have put me ear to the good and can't hear the tick. Should I be concerned? Is high idle with tick normal if it goes away when it warms up or is it a fair warning something is bad or about to go bad?
Mitsubishi - Galant :: Revving Engine / RPMs Started To Pulse Up And Down
On my way to the grocery store my car's RPMs started to pulse up and down (between 1 and 2) when driving. While stopped at the red light it would vibrate very hard. When i put it in park the RPMs would rise fast before i shut it off. It did the same things on the way back home plus the check engine light came on. A few hours later i put a little oil in it and drove it around my neighborhood and it didn't do any of the things it did that morning.
View 5 RepliesHonda - Fit :: Headlights / Interior Dome Light Pulse When The Engine Is On
I recently purchased a 2007 Honda Fit and everything is good except for one thing. The headlights, interior dome light, and one light on the climate control dashboard pulse when the engine is on. The brightness pulses to be exact, and it becomes more intense at higher speeds, and when the car is in gear and not in neutral (this is a manual stick). It is not noticeable during the day, but a pain at night.
I took it in to get looked at and two different mechanics (including a Honda dealership) said they cannot figure out what is wrong with it. They tested the battery, alternator and voltage regulator, and they all tested fine. The guy at the Honda dealership played with the wire to the battery and it got a little bit better. They said replacing the alternator (which seems to be fine) is the only fix they can think of ($650).
Golf IV / Jetta IV :: Steering Wheel Pulse Or Jump Fairly Violent
As the title says. Last night my MKIV started this jump in the steering. No load or decelerating, the wheel does a pulse or jump, fairly violent. I drove ten miles with no problem, then a couple jumps, then fine. Pulled tires and inspected, checked bearings, tie rods, ball joints. nothing obvious. Could it be something in the power steering?
View 4 RepliesGolf/GTI VII :: 1.8T - Long Cold Start Idle
I recently got my Mk7 1.8T manual brand new and have been wondering about the long cold start idle. It usually takes around a minute or two before the revs drop below 1000. Coming from a '04 Mercedes and '11 TDI Jetta, I can say those cars the idles dropped much faster. Is this normal with the golf?
View 11 RepliesGolf IV R32 :: Cold Start - Regular Idle?
just got my R32 a year and 3 months ago and love it. I came across my first issue though a couple months ago, when i start my car on cold starts before it would of course go to the cold start mode at over 1,000 rpm's before going back down after 30 seconds and depending on the weather i'd let it warm up anywhere from 5-15 minutes.
Well a couple months ago my car wouldn't do its normal cold start routine, i'd turn it and it made its loud pitch as if it was going to do the cold start and it just immediately went down to regular idle skipping the warm up, it did this for a week before i got it checked out. I went to a shop by me and he said that it might be a thermostat sensor so i replaced it and nothing. So he then pulled my throttle body off cleaned it did the whole calibration thing or whatever its called that you have to do when unplugging them and it went back to normal!!! Well after a month (two weeks ago) its doing it again. Then he told me it might be that the throttle body has some condensation frozen and isn't allowing the throttle to open like it needs too.
I live in a suburb 20 minutes north of chicago and i don't drive the car if it snows, i keep it in my garage. I have a CAI installed on the car that i put on back in March of 09 and a flapper that i just permanently opened with an IV clamp. So i don't have any big modification on the car...yet
Golf V R32 :: Rough Idle After Cold Startup
If my car's been sitting - say monday morning after sitting all weekend in the garage- it runs rough for a little while. Sometimes only for a few seconds, sometimes for a little while after the idle drops. The colder the car is, the longer and worse the condition. It feels like a cylinder isn't firing.
After a particularly cold and wet spell (I had the car outside) it ran so badly it threw a code for one of the cam position sensors and #4 misfire. I replaced both of the sensors. That worked a little.
Since I was due for 80k service and saw a misfire when damp, I replaced the ignition coils along with the spark plugs. That worked a little more. But, it still does it. What else could it be if not ignition? Sticky valve? something else?
Honda - Accord :: 1997 - Extreme Overheating / Engine Seemed To Pulse With Loss Of Power
97 Accord Lx - 215k miles - 4 cyl. - regular maintenance. It's been my daily driver for over 5 years and been running perfectly.
Yesterday I drove the 35 miles from work back to my town but before going home stopped to visit someone for about an hour. When I came out to leave I noticed a larger than normal amount of fluid in the drive. I just thought it was condensation from the AC and that it was more because it was extremely hot yesterday (100+).
When I got within 2 miles of the house the 1st thing was that the AC was not blowing as cold. I turned it off. Then the engine seemed to "pulse" with loss of power, and the temperature gauge was maxed out. As I pulled into the driveway the engine light and oil pressure light came on.
After it cooled down I checked and the coolant was a little low, so I topped it off. The oil was really low and I added three quarts to bring it to full.
This morning I started it up and let it idle while I finished getting ready (5-10 minutes) and the temp gauge was about 1/3rd of the way up (where it normally is). It sounded, felt, and drove as normal but after a mile or so the gauge was climbing extremely fast so I turned around and took it back home.
What it might be? Water pump?
Golf IV / Jetta IV :: 2003 1.8T - Cold While Idle In Drive Way?
Is it normal for my 2003 Jetta 1.8T to have trouble reaching operating temps from a cold start when letting it idle in the driveway with outside temps of 30F?
I recently had my thermostat replaced because my coolant temps never reached operating temps even when driving on the freeway.
Now with the replaced thermostat it reaches close to 190 after around 10 minutes of driving but if I am starting a cold engine and stay idle in the drive way it will not heat up to 190 even after 10 minutes.
When I tried a cold start with just letting it idle in the driveway for 10 minutes my check engine light came on giving me the P0118 code which I had before I changed my thermostat and a P0411 code.
After getting the thermostat changed I drove 100 miles to a destination and 100 miles back home the next day. A few days later I drove 22 miles to pick up a friend then 22 miles back without the check engine light coming on.
It was only when I let the car stay in idle from a cold start for 10 minutes that the check engine light came on and gave me the two error codes of P0118 and P0411.
Now I suspect the P0411 is from a leaking secondary air injection hose but the P0118 code confuses me as I switched out the thermostat and the coolant temp sensor.
Golf/GTI VI :: CEL For Cold Start Idle - Control System
So I got a check engine light... did a scan and it said something about, "Cold Start Idle-Control System" and then it also has misfires on all of the cylinders and that it is running too lean.
I automatically went to check the intake, took it apart and the rubber coupler that connects the MAF sensor to the stage 2 pipe has a rip in it.
Now I'm freaking out thinking that maybe water... dust... dirt... has gotten into the engine.
