Tiguan :: 2009 - Burping Coolant Out Of A Flange?
Mar 24, 2016
The TigWig runs great, tonight on my way home from work the MFD tells me to stop and check the coolant level. I stop and check the level and it is below minimum but still some in the expansion tank. On the trans side of the engine there is coolant on top of the transmission. I return to work to top off the coolant, everything is back to normal. The temp gauge never exceeded normal operating temperature. Half way home low coolant warning is displayed again. Temperature still never above normal. I top off the coolant again. It seems the Tiguan is burping coolant out of a flange or sensor port. It burps and then reseals. Mileage on the TigWig just hit 148k.

So I have been troubleshooting a few cooling issues and I am currently at a loss of WTF is going on with this thing. The truck is a 99 5.4L SD and has no heat and was burping a little coolant.
The truck was originally burping coolant out of the overflow tank. After verifying that it was not a head gasket by all means except the exhaust gas test. I replaced the overflow tank and cap.
Now the truck is holding pressure fine but I do not have heat. Here is what I have done:
I replaced the blend door actuator--no heat
I went to flush the heater core and since the quick disconnects were such a bitch to get off I decided ti replace it while I was at it. --still no heat,
New thermostat 195 deg --no heat
The radiator is brand new
Supposedly the water pump was replaced by the previous owner I have all the receipts for the truck so I could double check
Truck seems to circulate coolant fine i measured temps at the water outlet with an IR thermometer peaking at about 175~10 deg due to accuracy of the thermometer and heat loss due to thermal variations the lower radiator hose and reservoir coolant temps were around 76~10 degrees so the radiator is working as advertised . Truck doesn't overheat, granted after draining and replacing the coolant the temp gauge did climb some while driving until i worked out all the air pockets but still didn't overheat.

2005 jetta gli 1.8t automatic ( i know flanges are different from automatic to manuel) just recently found the leaking coolant flange. Can I change the flange without having to drain the coolant out of the system. my coolant is new because i recently had the timing belt/water pump etc done so its new coolant and i do not want to flush the system. also will i have to "bleed" the system if i just pull the flange of and replace it if that is possible.

I have a 99 vw jetta the coolant outlet flange nipple became brittle and broke...its the smaller 1/2 size hose not the two larger ones. Not sure how much coolant actually flows thru there and want to know if i can drive it a couple miles to a shop without it hurting the engine. I believe it's bone dry but don't know and i didnt want to add water since it's 32 degrees COLD. Don't want the water to freeze. The part comes in this weekend ...how far can i drive , with water no coolant....(vw coolant is expensive).

I took my 2009 VW Tiguan (which I purchased last week used from the VW dealership in Barrie Ontario) out for a drive earlier today. When I left, the ground under where it was parked was clean and dry. I came back after about an hour of driving and parked it. Then, this evening, after it sit for about 6 hours, I went out to put something in the car and noticed a puddle under the wheel. It hadn't rained and I could see/smell that the puddle was red engine coolant.
I checked the engine coolant and it was low. It's like it sprang a leak all of a sudden while it was sitting there - like someone cut a hose or something. I did a look over the engine with a flashlight and couldn't see any slashed hoses or anything. Tomorrow I'm going to call the dealership and see what they say. I'll update here with what I learn.

Bought a used 2000 Jetta, 2.0L AEG engine by the looks of it, 188k miles. Previous owner told me he did a bit of work on it, and acknowledged the coolant leak - have to fill the overflow ball about once a week. He said he recently replaced the timing belt, water pump, and tensioner pulley. Not sure if that has anything to do with it.
From what I can see it seems to be leaking at the outlet flange (see pics of rust).
Would any of this cause the water in the overflow ball to be rusty yellow (see pics)? Should I just go ahead and replace the ball and then the o-ring at the outlet flange?
I'm new to VWs, but am up for a bit of work to make sure it gets to 200k miles (bought the Bentley manual).

I've wondered why our cars make those burping sounds when you let off the throttle.
Example the new Ferrari P4/5 in this video does it a lot : [URL] .....
What the technical reason this happens?

I replaced a cracked radiator with a new one on my 2000 model B2500 a coupla' days ago, guessing at the refill, as I just got the truck and don't have a manual. Guestimate was pretty close, but I got some weirdness from the temp gauge for a bit. Temp gauge read cold (even though it was maybe sixty degrees outside) after idling for quite a bit, but would rise to operating temp if I ran the RPM's up a bit, then fall back to cold when I let it drop back down to idle.....never rose to above normal operating temperature, though.
I took a short drive down the road, stayed at normal temp, but dropped back down to cold when I parked it. Taking a peek under the hood, had air blowing out into the resevoir, bubbling like bathtub farts. All appears to be normal today, but I've gotta' take this truck for a roadtrip in a coupla' days and would like to make sure I ain't missed a step that'll send me hikin'.
What is the process of burping the radiator so's I can be sure it's all good?

New thread so this info can actually be found. Like most of you, I was irritated and embarrassed the first time I tried to top off my tank at a busy station, then had a quart of fuel pour back out onto the ground before I could get the cap back on. I did a simple fix that worked forever after. I always get a full fill, never have fuel burp.

So I'm about 10 mins from home today when the coolant low/overheating dash light (the key light) came on and started flashing. I got off the next exit and pulled into a Wal-Mart and notice I had no coolant when I lifted the hood. There was a strong coolant smell so I looked under the car and it was pouring out.
I got some more put in to get me home. I was 5 mins away and by the time I got home it was completely empty again. I can't see the leak looking from the top of the engine. When I look up it's coming out on the passenger side at the back of the firewall.
I filled it back up and just pulled the car into the garage. 7 hours later and the coolant is still full so it only happens when I'm driving. There was no oil present in the coolant leak. I pulled the oil dipstick and it looks normal, no milky color.
I'm having it towed to the local VW dealership tomorrow morning but just wanted to see what everyone's opinion on the issue might be.
Only 33K miles on the Tiguan The engine never ran hot. The needle was right in the middle the entire time. No engine mods other than a Chip, Intake, and Catch Can. I've yet to hear about either of those three mods causing this issue.

2010 Tiguan S FWD
My coolant temp light comes on randomly. It blinks and a sound beeps three times. After it stops beeping, the light continues to blink.
It doesn't come on all the time. It is very random. I connected the VAG-COM to see if there were any stored faults, but there were none.

Today was the worst weather ever since the Tiguan left the factory, it was -10˚C and it was parked outside.
When I turned the car on, the coolant light was flashing with a beeping sound. The indicator was acting normally and it stopped in the middle as usual when I drove about 8KM.
I then stopped and turned the car OFF and then ON after a few minutes and it was gone.
I searched and many people said something about topping up the coolant fluid. To me, this doesn't make sense because it only happened to them and I when the weather was cold.
Is there anything to worry about? the car is still new with 12,xxxKM.
Here is an image ...

Well, I had my flange welded rather then spending 1000$ or more on a Cat from VW but now I'm throwing an OX code. Would the broken flange cause this? It seems like a rather easy repair so I can do it myself, but should I worry I have a bad cat now? VW checked the codes and said they can't fully diagnose the code because I had the flange done so they aren't sure if the cat is bad. Should I just replace it myself and see what happens?

My mother-in-law just bought a 2009 Tiguan, and she's just over 5k miles. I looked in the owner's manual, and in booklet 1.1, page 37, it looks like service is every 5k miles, just like on my A4 and my wife's Passat. However, the dealer is telling me that VW recommends 10k service on the Tiguan. What am I missing? Is the dealer wrong? Am I misunderstanding the Owner's Manual?

I have been running the APR stage 1 for about 10 months. Yesterday, my vehicle refused to start. I got in the car and turned the key, The console lit up as usual, the second I tried to crank all the lights and display went off and the vehicle refused to crank. I suspected the battery, and tried jump-starting using a booster. While the engine cranked, it refused to start. I finally had it towed to the dealer.
First the dealer suspected battery issues. But today he calls and tell me they are going to have to replace the ECM. They claim they are not able to communicate with the ECU at all, and when they connected an ECU from another Tiguan and apparently that worked. Dealer claims its because of the tune.
The symptoms as I saw it - When I turned the key to the ACC position (with the Batt-booster connected) the console lights up as usual. If you keep it there, the lights also go out one after the other in the regular order. I was under the assumption this should mean the ECU is working and the circuits/sensors are passing the self-test. The MID, radio, seatbelt chimes etc - everything works with the booster/jumper connected - except it wont start
Therefore - can it be the ECU?

I have a 2009 SEL (NA) that doesnt have the convenience settings on the MFD, I have read this can be enabled at the dealership or through VAG-Com. Although my user manual states I can access it (which i cant) should i take this up with the dealer to enable the feature?

I have a 2009 VW tiguan 2.0T that vibrates violently when i hit 60mph, I mean pretty hard to the point where it doesn't feel safe to keep accelerating and everything inside not attached starts to rattle. Regardless Ive driven it to 100+ to see if it vibrates on higher gears and it does. I also have cruised on neutral downhills and stills vibrates the same.
So far this is what I have had it:
-Aligned and balanced tires twice.
-Had inspected and replaced both of the axles with new OEM parts.
-Had overall suspension inspected and everything seems fine.
-Checked the bearings by two different professionals, one used a dynamometer. came out fine
So far nothing has worked, and I am afraid or actually in denial that it might be something major with the transmission. I've researched and read various post around the web but i have not found anything beyond checking and/or replacing the the aforementioned parts.
I inadvertently hit 85 mph driving on an downhill interstate road and the vibration stopped, but came back again as soon as I slowed down to 60-80. Lets me to believe that there is something wrong with one of the transmission gears, probably 3th or 4th.

My 2009 Tiguan SEL with 120,000 miles is going through oil like crazy--quart a month with normal driving. More if under load--drive in mountains. We have massive amount of oil on driveway. So much I've had to put down oil dry.
The oil appears to be coming from the turbo. I noticed it on the back firewall and back of the engine near the upper timing cover. I took it in to mechanic and he confirmed the oil is blowing out of the turbo. He said a remanufactured turbo from VW runs about $1250 and it'll be roughly $1200 labor to install and clean the intake side.
The Tiguan has been a pain. Just replaced the air conditioner compressor over the summer. That was $1200. Have had two intake manifolds installed due to misfires. One was at my cost, the other VW's. Ballast on driver side Xenon headlamp went. Had to take the entire front off to get under headlamp assembly to replace that. And then there are those water leaks from the poorly designed sunroof drain tubes. I've replaced all four of them myself. They're about due to be replaced again.

I have a 2009 Tiguan SE 4Motion with a little over 82K miles on it. Hard to pin point exactly but somewhere around 65 - 68K the vehicle started shaking, noticeably but not ridiculously while driving at a decent speed, 50 mph seems to be the speed where it's most notable. I took it to the dealer and they diagnosed it as the tires needed to be replaced. I had the tires replaced a few K later but the shake was the same. I took it back to the dealer who did the basic balance troubleshooting but they were unable to find anything. I pressed them and they did some additional troubleshooting but then I felt like I was wasting my time with that dealer because they started looking at the floor and talking nonsense about road conditions.
I feel the shaking regardless of road surface or speed, noticeable but not violent, 50mph and steady seems to be most noticeable. I feel that it is transmission/drive train related because everything else it could be has been checked or changed but I could be wrong. I feels like it's directly under the vehicle, I have sat in different seats while someone else drove and it doesn't seem to be more noticeable on one side or another. When on the highway going a steady speed on it will increase and decrease seemingly randomly. It hasn't really gotten any worse over the past 15K miles or I would have brought it to a different dealer, but it really bothers me, especially since my Tiguan was so smooth when I bought it.
