Passat (B5) :: Noises At Cold Start


Aug 5, 2013

This noise started a few days ago. Only happens when the car has sat overnight, and only for about a minute or so. This is a 2005 1.8T with about 116K miles, timing belt done at 108K, AC compressor replaced in June. Oil changed every 5k with Mobil 1 0W40 - All filters and spark plugs replaced at 105K. Car is in Florida, temperatures are about 78-85F in the morning.

Nissan - Sentra :: Cold Start Noises During Transmission?

I recently bought my Nissan Sentra from Carmax, and drove it cross-country from Maryland to New Mexico for a job. I noticed along the way that from a cold engine start, whenever I would reverse, shift to drive, and turn the wheel to straighten, I would hear a noise that sounds like pulling the parking brake coming from the tire area. The engine also makes a knocking noise when the accelerator is pressed, but gets better as the engine warms up (which I'm told is a gasket). Finally, when driving from a cold start and the transmission shifts from 1st to 2nd, I hear a metallic clunk that sounds like someone hitting a metal shaft.

Any thoughts/concerns? I've read something about a premature bearing failure, if that's relevant.

Golf/GTI VII :: Brake Pad Noises At Cold Startup

In recent months I hear some new noises at cold start. First is coming from the front of the car, a few seconds I start reversing from a cold start, sounds like an automobile equivalent of my back cracking. Not metallic, more plastic-ish. Could this be "pad slap" from my front brakes? It happens about 75% of the time after a cold start. Second is from the rear-end but that is consistently linked to the first time I depress the break pedal once the car is in Drive, again after a cold start. Its more like a one-shot "thud" whereas the front-end noise is a bit more elongated.

Nissan - Noises - Maxima :: Whining Sound When Cold?

Ok, so I started the car this morning and there was a whining sound that sounds like winding of gears, It changed in pitch along with RPMs and when the car was in neutral (it's a stick) and the clutch not engaged, it was still there with pitch appropriate for idle RMPs. Later, when the car warmed up, the whine disappeared.

Passat (B6) :: Car Has Difficult Cold Start

Car is at the stealership right now 74k miles (CPO until 75k). Having issues with cold starts, weather has been getting into the 40's, and when coming out of work in the ramp the car has a very hard time starting (usually taking 3 times to fully turn over). However, in the morning coming out of my heated garage the car starts right up no problems whatsoever.

There are zero codes being thrown, zero lights on the dash. Brought the car in for diagnosis and the dealer has had it now for 2 days - still "unsure of the issue" but they have proposed that it is either a fuel pump (covered by CPO) or Carbon-Build up.

Passat (B7) :: Rattle At Cold Start Up?

The rattle only lasts for a second or two. Only warning light recently was airbag control module, addressed by Dealer. Also noticed recently, while doing some "spirited" driving, there was a deep-bass thump sound at the end of each gear change.

I've done forum searches for start-up rattle and found issues with timing chain/belt, in relation to the tensioner bolt, mentioned in reference to an earlier design(?). I was unable to find anything related to the B7/NMS.

No idea if it's a V6 issue, DSG issue or general VW issue. NMS V6? NMS DSG?

Passat (B6) :: 2006 - CEL Just Came Up / Cold Start Misfire

Bought a 2006 (later production) with 25,000 miles over the weekend. Couldn't pass up the price and the warranty (1 year left + CPO). Picked up the car Saturday at noon..... had to drive to DC for business and the CEL came on when I turned on the car this morning. I researched at lunch that it could be a cold start misfire but I am already pretty heated about this. When I get home tonight I am going to plug it in to my OBDII scanner and see what I can pull. If it is something bad.... I am giving it back to the dealership.

Passat (B7) :: AC Take Longer To Start Blowing Cold Air

My 2013 Passat SEL TDI has 40,000 miles on the clock and in the past few months I've noticed it's taking longer to start blowing cold air. I've had several summers already so I'm already used to it's performance in the hot summer months but this summer has been different. The A/C will not blow any cold air at all before the car gets going under load (it didn't need engine load before) and sometimes it just won't blow cold at all but just barely "cool" air. I'll sometimes be driving for a half hour and never get the A/C to really blow cold.

Other times, it'll blow just fine. It's the hit and miss performance that has me confused. I then bought one of those refrigerant bottles from an auto parts store that comes with a gauge to see if maybe I have lost refrigerant or it's low but when I checked the gauge the pressure was exactly where it needed to be. I just came off that dreaded 40K service at the dealership and am trying to avoid going back there at all costs...

Passat (B6) :: Loud Cold Start Idle

Check out how loud my cold start idle is. Still can't figure out why you can't hear the turbo on start up though. Even revving at idle you can't hear it that much. I've seen plenty of gti's with more exhaust restriction then i have and you can hear it clearly. [URL] .....

Toyota - Noises :: 1990 - Rubbing Sound Coming From Under Hood When Cold

My awesome 1990 Toyota Pickup (6 cyl., supercab), fondly named Ol' Rusty, has a measly 245,000 miles on it and still running strong. The one problem is that when it is very cold out such as this morning (-10F), I get a terrible noise coming from under the hood just in front of the steering column. It sounds like a belt rubbing, but I can't find it. It happens when I start going faster than 20 mph and goes away once the engine is completely warm. When it's happening, the speedometer jumps a bit. Interestingly, if I warm the truck up for 10 minutes or more so that the engine is completely warm, it still happens when I first drive the truck. Is this something I need to worry about or can I continue to ignore it like I have been for the last 3 years?

Camry 2012+ :: Constant Creaks And Cracking Noises During Cold Weather

My Camry Hybrid XLE has been at the dealership for a total of 26 days and 3 unsuccessful repair attempts relating to my dash that constantly creaks and makes cracking noises during cold weather. The shop foreman at the dealership also has not had a single camry (besides mine) come back for a noisy dash. The lemon law in my state kicks in at 30 days in the shop and/or four unsuccessful repairs and the dealer is well aware of this. I currently have the car and am waiting for a 'field technical specialist' to show up to take a look. I was told he/she comes comes 'once a month' but offered no more details than that. I noticed on this forum that some dealerships can call the specialist whenever and have them show up. Apparently mine only comes once a month... My luck will be that it will be too warm the day the specialist shows up and they will not be able to reproduce the issue!

Passat (B6) :: Cold Start Delay / Rough Idle

I got the fuel pump and fuel pump control module replaced. Now I am still getting a cold start delay (5-10 seconds to start) and it has a rough idle sounding like its misfiring. This happened when i picked it up at the dealership after a new fuel pump BUT! keep in mind it has been doing this for a while so i figured it was the fuel pump.

New oem plugs and the coils were replaced when i bought the car because the coils failed during a test drive I need to scan the codes but i will post. Also this only happens during a cold start. if the car is warm and i go into target or something then start it shortly after its fine.

TSB'S I think will fix this. [URL] .....

Passat (B6) :: 2006 2.0T - Sputter When Trying To Start It Up In Cold Weather

Cold start issues that my 2006 2.0T Passat is having. A few weeks ago, during a stretch of cold weather (10-20F), my Passat would sputter when I tried starting it up. It would either start and immediately shut off, would attempt to turn over, and generally on the 3rd attempt would turn over and run fine. I was only having this issue in the morning, and it would start fine when I would leave work (9 hour shifts).

I got my battery tested, and it proved to be failing. Replaced it. A few days later cylinder 4 started to misfire. I replaced all spark plugs and coil packs (85k on the car). During this service discovered that my oil had gotten some moisture in it and have off-white residue, flushed oil, replaced with new filter. A few days go by and I get code P2181 (cooling system performance). I cleared this out earlier today and it hasn't come back (50 miles later).

Are things just starting to go at the same time, or might there be another underlying issue? I have plans to flush the tranny and do the timing belt/coolant/water pump in the next month.

Passat (B6) :: 2.0T Misfires Sometimes During Cold Start After 6 - 8 Hours Of Parking

My 2.0T 06 Passat misfires sometimes during cold start after 6-8 hrs of parking. It happens very rarely. I have had the car for 4 years (bought it brand new) and the misfire has happened about 5-6 times. Is this normal? Just wondering if they get logged in the computer system so VW Service can see it? My car has got 47K miles on it.

Passat (B5) :: Cylinder 2 Misfire On Cold Start Ignition

I get a cold start ignition miss on cyl #2, then goes away (with a little revving), car then runs 100%. No problems during hot re-start. 2005 1.8T AWM. I replaced all four plugs (NGK OEM), all four coils (OEM latest rev), Coolant temp sensor (temp gauge was flaky). No other codes other than Cyl#2 miss and Random Cyl miss. Could I have a leaking (fuel dribbles out) injector on Cyl #2, causing a too-rich misfire when the car is cold started??

Passat (B5) :: At Cold Start Brakes Won't Working Properly

Whenever i leave work, i have to go in reverse to exit the parking lot. I noticed that the brakes are really ....mmm.....I am reversing and I press the brake to the bottom (it bottoms out very quick, not full lenght) and with it pressed at max the car barely stops. I almost hit the car that was parked on the other side..I freaked out cause I was at the bottom with the pedal and the car wasnt really stoping, so I pumped it up and it got harder and went lower to the bottom and it actually stoped and got responsive. I didnt notice that while going ahead from home, going forward. No issues whatsoever in normal driving. Pads are ok. Noticed that it is getting worse on hot days. Now I pump it up a few times before I even take out from park.

Lexus RX 2004-09 :: 2006 RX330 - Belt Squeaking Noises On Cold Days

I have a 2006 rx330 with belt squeaking noises on after warming up for say 10 mins on cold mornings, while reaching home I could hear the noises on cold days, the outside temperatures usually 35 to 40 F happens. While driving no noises, only happen on cold days when temperature is above 50 no problem. Should I replace the belts, how many belts are involved ? Tensioner problems ?

Prius Plug-in 2012-15 :: Cold Weather Driving (Rattling Noises) - Gas Mileage Down

Today, I experienced the coldest temperatures yet on my drive to work. At one point, I saw a '24F' shown as the outside temperature (although not unusual for April in Minnesota):

Expected: My gas mileage was down a bit. I was impressed it wasn't as bad as I would have expected from our 2005 Prius, though.

I should have expected: On the last 1/2 mile or so, when driving slow on the little bit of EV left while in the forced HV mode, I accidentally accelerated too much and forced on the ICE again (it had been previously on earlier in my 22 mile commute). This time, however, it was different because it didn't shut off immediately. I think the ICE had to do a second warm up. I'll have to watch that more closely next time (darn that cold weather)!

Passat (B6) :: Loss Of Braking Power When Backing Up After Cold Start

Experienced an almost unsafe loss of stopping power when backing up after a cold start? Every morning when I back down the driveway in reverse, by about the third pump of my brakes the pedal effort increases, the pedal becomes very hard (like when you pump the pedal when the car is off) and I have a hard time bringing the car to a stop to put it in drive. I need to take it in to have this looked at...
