Golf IV / Jetta IV :: Hot Rubber Smell When Under Periods Of Extended Boost
Feb 24, 2016
I have noticed that my car makes a hot rubber smell when under periods of extended boost. I live in CO and there are sections of road where, just to maintain highway speeds, my car will hit and hold 5psi as I motor up a mtn pass or very long/big hill...that could be a few miles with periods where it might just drop to 0 for a minute or two depending on traffic or a spot where things level out for a sec. (Downshifting doesn't really change this, only the rpm range...the hill/load stays constant)
Anyways, I don't notice this any other time. No visible oil leaks. The catch can is emptied. No smoke from engine or tailpipe. So I am fairly certain this is rubber I am smelling.
I am wondering if perhaps it's just the turbo getting hot enough to make the stock boost hose smell? It seems obvious to me that it is directly related to turbo heat. All searches I have done lead me to crayon smells or burnt oil...this is neither. Car runs fantastic otherwise, but this smell just sucks.

Is it common for the batteries to die if the car sits for extended periods? I just got this car and was told they disconnected the radio to keep from killing the battery. This car belonged to a school that drove it maybe once a month. I put a new battery in 2 months ago but just replaced the fuel pump yesterday and drove it home. However the battery had died sitting for the last 2 months and needed to be charged. I want to re-connect the radio. I took this car on a trade for some work I did and plan to re-sell it.

I've read other posts where owners report using previous gen for camping trips and leave the car on all night for AC/Heat. I have a similar but much shorter timed use case. When my wife is in shopping, I use my car as an office with laptop and phone going, and usually just bear the very hot days while parked for an hour, sometimes two. Would the 2016 Prius provide the opportunity to keep the car on in this way, and is there any detriment to its motors or electronics when keeping it on like this for extended periods of time.

I have a 1995 Lexus ES300 with 130,000 miles. This car is basically a rebadged Camry of the same vintage. Occasionally, when the car sits for extended periods (overnight or while I'm at work) and I try to start it, I get nothing. Not a click--nothing. This will never happen if I pop into a grocery store or other errands that are an hour or less.I've tried jiggling the floor shifter to see if it was the neutral safety switch and no luck. I've also tried putting the car in neutral with no results. I can also move the steering wheel rapidly left-right and push hard down onto the brake pedal with no obvious results. Eventually after 10 tries or so the starter motor will engage and it just starts. Could it be the ignition (where I put the key in)?

I have a friend with a 2012 F250. The truck has 100K miles and it does idle for extended periods. The other day his check engine light comes on so he took it the shop. They had not told him anything yet, but they did tell him that he had about a gallon to much oil. They said it was fuel.

Mine appears to be leaking where the rubber pipe meets the metal coupler. What actually secures the rubber to the metal? I will get a new 1 soon but will be a week or so as I'm all spent after a few other unnecessary car related items.

2015 6.7 KR... when idling for long periods of time the cab starts to smell like exhaust. I've also noticed when standing outside the truck with it idling (not in regen), it freaking stinks, bad! My 2003 never had this problem and idled for days (literally). Possibly leaky gasket here or just the nature of the 6.7?

my car into VAG COM and since then it hasn't boosted past 4 lbs. it has Revo stg 2, K04, aftermarket side mount, full exhaust and a couple other bolt ons. Before the car was spiking at around 23/24 lbs. after pressure testing the system I found that the turbo inlet pipe was lose, so I tightened it. Still no change. I tried holding the battery terminals together for 10 minutes to reset the ecu and I also tried clearing the codes through a handheld code reader. No codes even come up anyways for this. The car is a 1.8T.

So my 2001 1.8t Golf is having some issues holding boost. I have a Gonzo stage 2 tune, CTS FMIC, Forge 008 Diverter, Silicone inlet and MagnaFlow Exhaust. I've also done the whole Evap, SAI delete and installed a catch can.
Starting in 2nd or 3rd at WOT the car spikes up to 18psi and then progressively loses boost throughout the rev range. Close to redline the boost drops to 5 psi or so. It seems to be dependent on the revs. In fifth gear the car holds 18 psi much longer as the revs don't increase as fast.
There are no CELs. I've done multiple leak tests starting at the air box and plugging the pcv/catch can system as well as at the compressor side of the turbo. None of the tests revealed a leak anywhere in the intake system. However, when I stuck my ear very close to the valve cover I could hear what sounded like a very small air leak coming from inside the valve cover. I took a look at the wastegate actuator and it seemed fine, no play in the rod, no loose bolts and to move it just requires enough force to compress the spring and it returned to its original position.
My thoughts are that it could be a fueling issue or turbo in the process of dying maybe.

Just noticed today that I have a slight drop in boost. Normal boost is 1.5 bar but today it is running slightly lower boost and does not have the same pull through all the gears.

I just recently notice a whistling noise when I hit boost. I'm not sure but it sounds like it is coming from my gauge. I'm not losing boost pressure. I do have a glow shift gauge. The most recent install was the TIP which I clamped on to the turbo but I'm wondering if it isn't on tight enough.

I was riding along today everything running fine then I came to a stop sign and when I pulled off my car wouldn't run 10 psi of boost it was only running 5 psi so I when to a buddys checked everything over and all my piping looked fine so I went up the road and everything was fine so when I started going home it did the same thing pulled of shut the car off pulled off and it was fine again.

I think my stock DV is going bad, my car makes a weird noise under boost?
1. Only happens when first starting the car after it has been sitting for an hour or a few. (not overnight)
2. Does NOT happen when first start in morning.
3. Goes away after like 5 minutes every time and the normal WHIIISHH sound comes back like it should when I step on the gas.
4. It does not make the sound at idle.
This recording I made was of my car being revved up after it sat for one hour.

Was bleeding my brakes and clutch. Using a power bleeder and it seems as though I put a little too much pressure into the system. The Slave cylinder's green rubber boot filled with brake fluid and began leaking a little. Did I blow a seal? Is this normal with pressure like that? I feel like pushing the clutch in would give more pressure than my little hand pump gives...

Replaced my coil packs/sparks, and just got around to changing my N75 valve today. The rough idle issue is gone but now when I go WOT it boosts but goes from 15psi-12-13-12-14-12...etc. I've checked and there are no boost leaks. I do have a CEL saying I need a new bank 1 sensor 1 Oxygen sensor. If it is that, why did this problem arise as soon as I changed the N75 valve and wasn't present earlier?

I was having an issue with my car not going into boost so I plugged my code reader in and it had 2 codes 1 was p1200 n249 malfunction and the other was diverter valve malfunction so I did the quick easy one and got a new factory diverter valve but it still doesn't go into boost and still reads p1200 n249 what do I need to replace or should I do the n249 bypass it's a bone stock jetta 5 speed.

I just got done with a complete engine rebuild on my 02 1.8t jetta, had everything hooked back up and went to start it for the first time and it wouldn't. I went back looking for loose connections, nothing. Worked and banged my head for a day or two, I had fuel and spark but couldn't get it to fire. Finally I "choked" the intake to see if it was getting too much air and it fired right up. I unplugged my map sensor giggles and it starts up perfectly. I then hooked everything back up and what do you know it starts up and runs fine, but if I plug the sensor back in it kills the motor after about 10 seconds of running and won't start until I unplug the map again.
Car runs and drives but wont boost over wg pressure but that's probably because sensor itself is unplugged. I just wanna know what could cause it besides the sensor itself being bad. I ordered a new one waiting for it to get here (hoping it fixes the problem).. And I'm talking map (manifold absolute pressure) not maf (mass air flow), just in case people are confused.

I got a Mk7 in October and my Mk4 has unfortunately been parked since. I started it and let it idle to warm once a week or so when I went on Vacation for 10 days. Before going on vacation I moved the car and after warming up everything seemed to be normal. Unfortunately I neglected it once I got back and haven't started it since the beginning of December. I'm selling it here soon and so went out to spruce her up tonight and upon trying to start the battery was dead so a buddy came over and jumped it.
It started right up but immediately was idling funny which I assumed was because of the cold (it's 25 degrees F tonight and has gotten in the negatives in the past few weeks due to snow storms). I shut it down and checked the fluids which were all pretty low especially the oil due to a small leak. So I topped off the all the fluids and started it again and let it idle to full warm.
I decided to take it for a drive around the block and it was still driving pretty rough, no knocking or anything but the engine was "sputtering" and the CEL was on and flashed when I gave it gas. I'm running stock boost so my gauge usually reads around 12psi but is now only going up to 3-5 psi and the vacuum is only at -15 which i think used to idle at -20. I drove it to the gas station and filled it up from a little less than a half tank but it's still running the same and there's a slight burning smell from the exhaust.
I was worried it was my turbo but it was perfectly fine a month ago. I was thinking of throwing some Seafoam or Heat.

Okay, here's the car
AWP 1.8t mk4 GTI.
- stock DP
- Forge 007 splitter adjusted 25 clicks
- Swiss cheese stock intake with k&N high flow
- APR stage 1 93 tune.
My boost gauge is currently reading peak of about 15-16 psi. I replaces some vacuum hoses that appeared to be worn, and to no avail. I have no CEL, and no codes thrown at all. This sound like a boost leak.

I just replaced my my k03s with another one with only 20k on it. After I did this, I noticed a loud screech sound when in WOT. The screech lasts a little bit after i left off the gas when revving in neutral. I've been doing research on here, and I've read that it could be a boost leak somewhere or even the turbo dying. The shaft play is minimal though.

Recently got my VCDS USB cable that I can use on the newer 1.8T Jettas and I haven't found a measuring block for boost or MAP data. My Scan Gauges don't give a MAP data field either for the 1.8T engine, while it does for the TDIs.
Where do I find this data? Surely the ECU monitors boost?
Couldn't find anything while hooked up to the Buddys Passat 1.8 that we did a TB and thermostat on yesterday.
