BMW :: 1999 - At Cold Start Strange Noise From The Engine
I have a 1999 BMW 3 series, 112K, 5 speed, immaculate condition, only full synthetic oil used. After a cold start - even today at 55 degrees - I get a strange noise from the engine compartment which gets louder according to RPMs. The BMW dealer replaced the oil separator for the motor ventilator and some of the respective hoses and valves associated with it. They also checked the oil pressure when the motor was hot and cold and advised it's fine; however, the noise is still there. (A different BMW dealer service advisor said, just after hearing it, it was an oil pump issue.)
On an unrelated note, when the motor is warm and I'm in stop and go traffic, the idle speed will sometimes go up and down (500 RPM - 900 RPM), and when it reaches 500 or so RPM, it dies. The car always starts back-up right away. Spark plugs are new and I used OEM BMW spark plugs. My thoughts are the idle air control valve.
Otherwise, the car is great; yesterday I took it on a 250 mile RT highway trip without any problems.

Camry :: 2005 SE 2AZ-FE Noise On Cold Start Up
2005 Camry SE 2AZ-FE 4cyl 5 speed manual bought new well maintained 119000 miles. Makes a funny noise on cold start up when temp is below about 20 deg f just the first start up of the day. The noise sounds like a ZIP and is just for a second or 2 at the most. I can feel it in the steering wheel like a high frequency vibration. Seems like it's doing it at not quite as cold a temp but has been doing this since the first winter I bought the car new.
Hard to isolate without a second person standing out there in the cold, definitely coming from under the hood. I'm thinking it could be the idler pulley. Serpentine belt is original but has no cracks and is properly tensioned. Since it's done this since day one I'm hesitant to start pulling things apart. Car runs great aside from that. Mobil Super High Mileage oil 4,000 mi change interval, Toyota Filter always. The noise is just after the engine initially fires not starter related in my opinion.
Camry :: 2005 - Only Starting When Engine Is Cold
1. 1 month before I change my car battery.
2. Last night, after coming from Office i.e., around 50 KM drive. I witched off the car and had my dinner, let say after a gap of at least 3 hrs, I try to restart my car again but I could not. Even I can notice that the battery is not discharged as all lights are functioning properly & even center lock is working fine.
3. Then I use another car for jump start then the immediate car started. After driving for another 25 km, I switched off the car & try to restart again but I failed.
4. Today, after a gap of almost 15 hrs, again I tried to start the car then immediately it got started without showing any difficulties.
5. Again after driving around 20 km, again I switched off the car & try to restart then its not restarting.
I am confused, what could be the problem. Sometimes, it starting when the engine is cold & sometimes it's not starting when the engine is hot.
Camry :: 2005 4 Cyl - Rattle Noise Right At Start Up On Cold Mornings
I bought a 2005 Camry about 3 months ago. It has the 2.4l 4 cyl with about 139k miles. The car seems to run perfect, but it has a rattle noise right at start up on cold mornings. It only lasts for the initial 1/2 second start up, then it's gone. I'm thinking it's probably just a heat shield rattle or something, I just did a full synthetic high mileage oil change on it and that didn't work, so that just makes me lean more towards heat shield.

So I posted here a while ago with a question regarding my Golf and a strange whining noise it made on cold starts. I took it in to the dealer to find out what was going on (warranty) and they said it was the secondary air pump making the noise and that it was normal.
View 9 RepliesCorolla / Matrix 2009-13 :: Strange Whining Noise On Cold Mornings
I've run into a very strange whining noise in the mornings on my 2010 Corolla S.
I've done some diagnosis and the issue only occurs when it gets chilly out (below about 50 degrees). When you go out to the car in the AM with things dead cold and turn the key into the run position before you start it the noise starts up right under the dash on what sounds like the passenger side. I've tried the fan on and off and it doesn't seem to affect it. It does seem to be lasting longer and it really sounds like a bad bearing in a small motor. As the car warms up the noise disappears and doesn't reappear unless it cools down all the way, which usually means it has to sit overnight.
It doesn't seem to affect how the car runs so I'm guessing it's not a primary system, likely something with climate control or AC?
Prius (2004-09) :: 2005 - Strange Whirring Noise
I have a 2005 Prius with 218,000 miles. Over the past month or two it's started making a horrible noise, which has finally gotten to the point that I can barely stand driving it. I used to keep my radio around 25 or so, but now need to crank it to twice that to hear anything. I can't tell what it is - it sounds vaguely like wheel bearings, but somehow different. The front bearings and a trans drain/fill was done by an independent shop 6,000 miles ago. That shop says the noise is the transmission and definitely not the bearings. My Toyota dealer says the noise is the bearings and definitely not the transmission.
Here are two videos I took this afternoon, which seem to more or less capture it, though it does sound a bit different recorded on a phone than in the cabin:
(this one has a clearer example of the noise)
Background:
I didn't have any complaints with the car until just before the 200,000 mile service was due, when I started hearing front bearing noise (I've had bearings done in about 5 vehicles, so it sounded pretty obvious to me). I brought it to the dealer and was quoted an outrageous amount for front hub assemblies (they told me they couldn't do the bearings, only the whole hub assembly), sway bar end links, alignment, transmission flush, tire rotation and the engine top end service.
I got a much better quote from my local mechanic who I've used for about 3 years, so I had him do the work. This was back in June, at 212,417. He said that they'd never done the flush on a Prius transmission before, but they had the shop manual and were sure of the procedure, and that their Valvoline rep confirmed the correct fluid, and gave them a written warranty in case of any problems. He did note that "a fair amount of metal shavings came out with the old fluid" when they did a drain and fill (not a flush). He also told me that the tires were worn unevenly so I could expect a bit of road noise after the rotation and re-alignment. They an oil change, sway bar end links, front bearings, tire rotation, alignment and reans drain and fill with Valvoline Max ATF, "Toyota Type WS fluid spec." He told me the same thing about the front hubs being complete assemblies, and the part he listed (PBR930641) appears to agree with that.
Prius (2004-09) :: 2005 - Car Making Strange Beeping Noise, CEL, ABS Lights Come On
Have been driving my Prius with no issue all week. I leave the car home and take my wife's vehicle, while she drives it today without incident. I come home and hear the car making some strange beeping noise (NOT the anti-theft alarm, different). I hop into the car and try to start it, and the check engine and ABS lights come on for a second before other lights in the speedometer area kinda half come on. The gear indicator comes on and has boxes blinking on all of the letters.
The MFD never comes on.
It appears to be the 12V battery dying. The car has 150k miles and I have never replaced the battery, so it seems I was way overdue for this.
Camry :: Sputtering Noise Come From Engine But Only After A Cold Start?
What would cause a sputtering noise to come from the engine but only after a cold start meaning starting in the morning and after work but goes away after I drive for a min or two and doesn't come back until the next morning or after work. It sounds almost as if say you had a hole in your flange and drove it around. Its really weird it happens a few times a week for the psst 2 weeks but hasn't happens ever before that. Could it be the water pump in its way out? Oil levels fine fluid wise everything topped off.
View 4 RepliesPrius (Gen 2) :: 2005 Engine Makes Noise When Cold - Could Be Piston Slap / Valve?
My 2005 with 160k miles has engine noise when cold.
I talked to a couple specialists who said it could be valve noise another said valve noise would not abate when the engine warmed up. He suspected piston slap. A valve adjustment is pricey and the local independents are afraid to touch it given the complexity and needed shim packs. If it is piston slap I would be disappointed after spending a pile of dough to still have the same noise.
Have I missed a possible cause?

View 1 RepliesGTI 337/20th Anniversary :: 2005 - Strange Clicking Noise From Rear Left Wheel?
Recently picked up a 05 GLI with the bbs wheels. Last night i was driving into my parking garage and noticed a clicking noise comming from the back left wheel.
I lifted the car on that side and spun the wheel but it didn't make the noise. But once i set it back down and rolled the car the click came back. So i'm guessing it has something to do with pressure being applied to the wheel.
Camry :: Cold Start Up Noise On 2AZ-FE / VVT Oil Screen Location On Engine?
I have the cold start up noise on my 2AZ-FE Camry. It is from the VVT gear.
I have found the Solenoid on the back side of the engine but can't locate the bolt that has the screen inside it.
Where the VVT oil screen is located on this engine?
Camry :: 2008 V6 Making Noise When First Driving And Engine Is Cold
My 2008 Camry V6 has a noise that happens when I first start driving forward right after the transmission shifts from 1st to 2nd gear, from inside the car it sounds like it's coming from the engine compartment on the driver side. I've figured out that the noise happens only when the engine is completely cooled down and it happens only once until the engine is cooled down again. It doesn't do it when in reverse, however if I reverse first it will still occur when I start pulling forward and the transmission shifts.
I brought my car into the Toyota dealer and they say that they don't hear anything wrong. They ended up replacing an axle because a boot was torn so I was hoping that it would end up fixing the issue but it made the noise right away when I picked up the car.
I have a video of the noise happening... turn your sound up and you'll hear it right at the 0:14 second mark of the video: [URL] ....
I have literally 89 miles left on my extended warranty so I really need to get this fixed. Back to Toyota...
Camry :: 2007 - Rattling Noise Mostly When Engine Is Cold Started
I got a 2007 Camry 2.4 l4 engine under the hood and its didn't start this until we had a garage change the oil never did this when toyota changed it. Mostly when the engine is cold started there is a little bit of a rattling noise it will make until engine is warmed up and once its warmed up at times it will still sound kinda bad when it runs at normal engine temperature but this mostly occurs on cold starts and didn't start doing it until a regular garage changed the oil this never occurred when toyota dealership changed it
I don't know what kind of oil that was used in it last at that oil change but it started that about a week or so after that. Car currently has about 133,000 something miles on it ... Its not that loud of a noise but its noticeable when all doors are closed.
Camry :: Squeaking / Dry Bearing Noise On Cold Engine Start
My Camry 2grfe now has almost 60k miles and it started making a squeaking/dry bearing noise but it goes away after about 2 minutes of running. I was going to replace the serpentine belt when I get a chance, its a tensioner or a pulley bearing? Can the bearings in the tensioner or pulleys be replaced instead?

My 2005 Toyota Camry has developed this rattling noise that is always there when the engine is on. When the engine is at higher RPMs, it becomes more noticeable. Here is a quick video I took of the noise for the audio of it..
It was too dark for me to check tonight to see if there is low oil or anything (there are no lights lit up on the dash).
Camry :: 2007 SE - Noise At Startup On Cold Engine When Temperature Is Below Freezing
I have an 07 SE (manual transmission). In cold climates has noticed a noise at startup on a cold engine when the temperature is below freezing (colder than -5C or so)?
The engine has to be cold (like sat overnight) and the outside temp has to be cold. Then at start when I turn the key, the engine starts fine, but as I release the key from the start to the run position I hear what sounds like the starter motor make a noise (short zipping sound).
At first I wondered if it might be slow to disengage, but if that shouldn't make a noise because the gears should be meshed ok? There is no noise with a warm engine, or with a cold engine on a mild day.
