Occasionally when driving I get almost a earthy smell. Not mildew but more like pond water. I checked the cabin filter it was dirty but had no smell to it. It does have a front & rear HVAC system.
View 2 Replies'05 1.8T with 30K miles: Sometimes, when the car is stopped and idling, an oil burning kind of smell comes in through the ventilation system. I can also smell it outside. I had the dealer (a good one) check it out. Couldn't find anything. No sign of leakage anywhere. Where I or they should be looking? When I open the hood during these smell events, I can't see any smoke or tell exactly where it's coming from. It seems to be around the driver's side of the engine, but all the heat is on the other side around the exhaust and turbo. Weird. It's really starting to annoy me.
View 3 RepliesUsually in the OBS 7.3 but a buddy of mine with a 2003 6.0 is having some issues. When he romps on the pedal but when he does so he claims he can smell exhaust in the ventilation system. I rode with him and smelt it as well. So I inspected all exhaust clamps and piping as best I could and did not notice any soot or leaks while running. I don't know if it pertains to it or not but his heater only works on defrost.
View 4 RepliesThis morning I went to drive my car and the check engine light, along with the D4 light on the dash went on. The D4 light started blinking. When I drove the car, it felt really heavy like it was not shifting right. There was also a bad smell coming from the hood. I took it to get the code read and it was P0758. There seems to be something wrong with the transmission and I am just wondering how much it will cost, and if it is worth it. The car is in great shape, I just had the timing belt changed.
View 1 Replies1987 Acura IntegraI noticed that the pop up headlight dash warning light intermittently comes on when the engine is running. Now Battery light (charging light) and pop up headlight warning lights are coming on simultaneously (still intermittent) when the engine is running.
Battery is new. Headlights (and pops up) are working. High beam is working. Parts store used their meter to test the battery and alternator - it passed - however, their equipment initially did not detect the battery voltage - I was told that it needs to be repaired - but when the engine was running, he was able to do the test - it passed all the test.
There is a separate switch to just to pop the headlight - when I push the switch, it makes the sound as if it begins to pop but there is a hesitation and then it fully pops it up (only issue that I can observe) - whereas when I turn the headlight on, it properly pops it up and turns the headlight on - whether engine is running or not.
Been noticing this lately. Kinda smells like coolant I think but it's intermittent and for a short period of time. Notice it more when turning the heater on or when setting the temp to a higher setting.
Havent noticed any leaks on the carpet. Heater core? Why intermittent?
I only have about 3,500 miles on my car, every now and then I get a faint smell of possibly antifreeze when I open either of the front doors after a good drive. It's very strange because if I try to locate the source, the smell goes away. Once I exit the car and sniff around, there is no smell in the wheel wells, in the front grill, or under the hood. I then try to sniff under the car just under the front doors, and there is no smell! It is driving me crazy because it does not make any sense. My antifreeze level did not drop, and there is no evidence of any leaks. I didn't put it on my lift yet to examine it carefully, but I'll do that on the next oil change. I was wondering if there are possibly some hoses that go to the rear of the car for the rear a/c and heat. If so, maybe there is a slight leak on one of the clamps?
View 14 RepliesI live in NM. It's been excessively hot here this summer, 95+ daily for the past 2 months.
Yesterday while I was driving I noticed a weird feel in the accelerator pedal. Almost like a mini-misfire. It was intermittent. Maybe did it 6 or so times in a 10 minute time span. My wife couldn't feel it in the passenger seat but I definitely felt it through the pedal. There was no MIL light during or after the incident.
We get home, she gets out on the passenger side and there was a strong fuel smell (tank, filler, and filter are on that side). By the time I got the car up in the air and the rear passenger tire off and fender liner out the smell had dissipated (probably evaporated due to the high temperature). There were no noticeable leaks. No dripping. Before I had it in the air I definitely smelled fuel underneath the car around the rear passenger side. I opened the hood and didn't smell or see anything in the engine bay.
I called VW customer care and they informed me this recall of the fuel tank ventilation valve was performed back in 2009 but the symptoms explained in the recall are exactly what I experienced. I verified the recall was done using my VIN number search on NHTSA's Safer Car site.
I can imagine that although the recall was done 7 years ago, it's still possible for this ventilation valve to fail. Especially because the recall states high ambient temps are a factor.
I have a legit VCDS but have not scanned it yet. Wife is off today so I took her car. I plan to go home, scan the car, and try to reproduce the issue before taking the fender liner out again. I have the means to do my own work but if I have to do something like drop the fuel tank I'll probably take it in.
the car's battery light still has not shut off and now the defrost button stays on for about one second. The engine bay sometimes smells of something burning, too.
No CEL, so what's going on here?
We bought our 2002 Honda Civic new and have maintained it exactly as specified. Intermittently when we turn on the AC/heater we get a horrid smell, sometimes like dirty socks, sometimes like vomit, sometimes like damp basement. We recently had the cabin air filter changed. It doesn't happen every time we turn the AC/heater on, but enough that it can be very irritating!
View 2 RepliesA few months ago I bought a used 2008 Mazda3s sedan, and ever since I get an intermittent burning rubber smell from my rear left wheel. I recently got new tires, brake pads, and had the rotors turned, with no change.
The smell does not always happen, it will be there maybe one out of 3 or 4 times, and it is more likely to happen after long drives (e.g., one hour highway driving).
The wheel well also feels very hot. The obvious answer would be that the brake caliper is sticking, causing friction, heat, and the burning smell. However, if I touch the rotor it feels the same lukewarm temperature as the other three.
One additional thought is that this is caused by the exhaust, which is right next to this wheel well. I have noticed that the area of the floor of the trunk right above the exhaust gets very hot, which I had not seen in any other car I owned.
Could it be that the exhaust is causing the rubber of the tire (or something else) to overheat and smell bad? Visually, it does not look like the tire has a different wear or different appearance, compared to any other one.
This may or may not be related: my handbrake seems to be useless If I leave it on I can easily drive with little to no noticeable slowdown... I guess the previous owner did not read the part of the manual where it says you have to release the handbrake before you drive.
I have a 2014 V6 Mustang. Recently I've begun to smell that special scent of burning metal intermittently, more often at slower speeds or when stopped completely. In addition I've noticed that my mileage has been dropping a bit and that the car doesn't pick up quite as fast as it used to. Today on a hunch I put the car on a non-incline surface and let the clutch out relatively quickly. I was shocked to discover that it didn't stall - it absolutely would have when it was newer. The brakes also don't appear to be shedding dust so I don't think one of them is locking up.
Normally these would be signs of a clutch going bad. I'm suspicious because my car only has 25,000 miles on it. It has been driven through two Michigan winters and thus subjected to some abuse, but even if I were riding the clutch daily (I would never) I would be surprised to see it go out so young. Should I be looking at something else, or should I just break down, go to the dealer, and fight with them until they replace it?
When I turn the key all the way over, I hear only one click, and no engine sound. Playing with park or neutral positions do nothing. Battery and connections are good. I am getting a raw fuel smell out of the tail pipe after it finally starts. The check engine light intermittently comes on, by now it is mostly on.
My guesses are: fuel pump/relay problems, starter/connection problems.
I have a problem with the internal ventilation: the fan works but no air exits through vents whatever the position of the control button. Where can I find a schematic of the ventilation system, I do not know how to disassemble it....
View 3 RepliesThese super-hot days our TS had started to develop a very strange problem:
- when you first start the engine the A/C works normally and cold air blows from the front vents on A/C or MAX as usual
- if we shut-down the engine and try to engage A/C or MAX again the cold air would only come-out through the top (windshield) and low vents - no more front ventilation
- all solenoids appear to be working (moving)
I have a 2015 Prius. when I operate the ventilation system without using the AC, and the air on by-pass I get a rear bad smell. With 6500 mile I should not be needing to spray disinfectants etc into the ac system.
View 19 RepliesHave a problem with the rear air distribution. I can not get it to work. What am I doing wrong?
View 6 RepliesSo I used to have my phone holder clipped to the vents to the left of the steering wheel. Key words, used to. One day, one of the clips snapped as I was putting my phone into the holder, sending a piece of plastic about 2 inches long into the vent. At first I could see it, but since I was driving, I couldn't fish it out. Sure enough, on a turn, it disappeared completely into the dark void that is the ventilation system. Now, on every turn, I can hear the little sucker careening back and forth. Sounds like I'm gonna have to disassemble the dash to into the pipes, but maybe there's a more harmless way.
View 6 RepliesI noticed today that the temp got to be about 70 degrees today. I went to put on the ventilated seat, but it did not blow cool air. when I first got the car, it felt like as soon as I pushed the button cold air came out, It actually felt weird at first.
Now I can hear the fan going if I turn everything down, but it did not get cool.
The other day I was driving a rather long distance and stopped to take a nap inside the car with everything off. The solar ventilation system started to do its magic, but it only seemed to operate in bursts, i.e. no air flow, 20 seconds delay, slowly increasing airflow to what seems like a max flow for about 5-10 seconds, then no flow at all again for maybe a minute or so. It seemed odd, and not very efficient at all as opposed to just keep the fans going (in plain sun that shouldn't be a problem).
View 12 RepliesYesterday I heard a high-pitch noise/squeal coming from the vehicle and after some searching, figured out it was from the ventilation fan. It went away after 5 mins of being on but is rather annoying. Not too keen to take it in as I'm sure the dashboard will need to be removed and afraid it won't go back in perfectly.
