Golf IV / Jetta IV :: Code P0441 After Timing Chain Replacement - Rough Idle And Reduced MPG
Oct 24, 2014
2001 Jetta GLX, 12v 2.8 VR6 Automatic, 157k miles.
Relevant Info: P0411 code, unknown if associated with my slightly rough idle and recently reduced mileage (down by 3-4 MPG). I see 2 N80 valves, one by the power steering reservoir and one behind the throttle body attached to the fire wall. I removed them both, got a tiny bit of what may have been charcoal out of the lower valve and tested both with a 9 volt battery. Both were closed with no power and open when I attached the battery. I cleared the code and it returns within 30 minutes.
Possibly irrelevant info:
Changed the timing chains 3 weeks ago and the code popped up just afterward. Prior to changing the chains, all I saw was a Cam Position Sensor code that is now clear. The slightly rough idle was present to a greater degree before chains were changed but has improved.
SAI solenoids look good but their little rubber hoses don't look fantastic. Could this contribute to the rough idle or is it not part of the vacuum system?
Ignition coil is new and all plug wires tested to about 6k ohms.
I've looked up other's experience with P0411's and have seen the list of possible causes. Wondering if I'm missing a possible cause, if I can test the system further without having to buy parts etc, if the reduced mpg's and rough idle are related...

What to do if your timing chain tensioner fails and wipes out the valvetrain. Go to www.vwusa.com and click the contact us page. Find the link for "online chat" and open a dialog with a vw rep. Have the vin, milage, purchase date info handy and tell them what happend.
Maybe I just got lucky, but I thought my (second owner) 2012 GTI with 46000 mi was toast, the rep (Bill H) told me not to worry and set me up with a case number and the location of a dearship that will confirm the damage and replace my engine.
My experience is in direct opposition of what I have read on forums when people take their GTI's to the dealership first, then after hagling with the stealership managers for weeks on end finally end up emailing vw corporate (which takes weeks to respond) and finally having the issue resolved.
Of couse, this is only if your car has not had the warranty run out. I thought that being the second owner voided the powertrain warranty...again that was false.

2.slow bev engine / 2004 golf gl / 105k miles
The car sat in a garage for 9 days. It had no problems before. Now I have a p0441 code that comes back after being cleared, and an intermittent gas cap light. Is there a typical problem that causes this?

I have a 2000 jetta 2.0, and the idle seems to rough and when I start the car it seems like I might stall.

Changing timing chain tensioner? Mine is making the rattling noise on startup. Tried searching one internet for any DIY's out there. Haven't really found any good ones.

I have a new style 2004 F150 XLT supercrew with a 4.6. Well, I just hit 300,00 miles earlier this week. The truck has performed pretty much flawlessly over the years (and still does). I've replaced front hubs, IWE's, brakes, fluids, etc, but have NEVER opened up the engine. Is it time to replace the timing chain?
First thought is ,yes, like 50,000 miles ago, but... It has some dents and dings and the rust is getting to it. There is 300,000 on the transmission also... Virtually no residual value- If it strands me on the road, it's time for a new truck.
On the other hand, it only burns a little over a quart at 3000 mile change intervals, the transmission seems strong. I just shampooed the cloth interior and detailed it. The thing looks great from the vantage point of the steering wheel.
No engine issues at all- no rattling, etc.

Check engine light is driving me crazy, comes and go depending on weather conditions.
When "ON" the code I get is P0441 and P0171. The engine hesitates for a second or two,then stabilizes.

I have a 2003 Toyota Corolla with a leaking timing chain tensioner. I was able to locate a procedure for replacing the tensioner but it didn't say whether the no. 1 cylinder had to be @ TDC or not. What is the proper procedure for this repair?

Can you change the tensioners and guides without removing the chains or getting the cam lock tools ? Doing a in truck repair to fix a squeal sorta noise at start up without the belt on coming from passenger side valve cover that lasts for about 5 sec. oh fyi CRC new freeze off works wonders compared to jb blaster for my tear down so far!

After running to operating temp, if the car is turned off then restarted (like you would at a gas station, which is where I notice this) the engine will turn and turn and turn but not fire. I have noticed that stomping on the acceleration will cough it into life during this procedure. This doesn't happen every time and I have recently run high octane gas during a long distance trip.
106K miles...
Recent p0441 fault codes and gas cap warning light...
No other problems or codes...

Having trouble with my '00 Jetta 2.0 A/T w/ 98K miles. Had the water pump replaced @ a year ago (for the 2nd time, the 1st replacement died after <15K miles.) The car has had issues with rough idle when started, especially with a cold engine, since before the 2nd water pump. I've replaced the coil pack, thermostat, and coolant temperature sensor in the recent past in addition to the water pump & timing belt.
The gas mileage sucks, and when it's idling rough it doesn't "idle up", & will stall if the gas pedal is pressed with 30 secs. of starting. Otherwise it seems to run fine. The coolant temp. sensor was replaced after a CEL indicating it was bad. The CEL went off after it was replaced, but it's now throwing a P1296 Cooling System Malfunction. I have noticed the temperature gauge fluctuates instead of staying around the "middle" since the 2nd water pump replacement, and will run "colder" in colder weather. Since spring is here, the temp. gauge stays around "normal", or the middle.
Some research online says thermostat OR coolant temperature sensor. Since the gauge registers normal now, I'm leaning towards a bad temp. sensor...?
Does the hard start/rough idle and the cooling system malfunction CEL could be related?

Just did the timing chain, phasers, oil pump and lash adjusters on my 05 5.4 s-crew. Always had a bit of a rough idle but now it's worse. If the truck idles for an extended period it sets a p0300. Just off idle the misfire is gone. It does seem a touch down on power but otherwise runs great. I did have the plugs out during the work. I cleaned them, applied anti seize and re installed. The previous owner had the plugs and COPs changed 10k miles ago. Plugs are motorcraft and coils are aftermarket.
I monitored with oreillys crappy scan tool and the miss only happens at idle. It is not a dead miss; unplugging COP on each cylinder still makes it worse.
Truck idles warm at like 570 rpm and if I hold my foot on the pedal to raise rpm a bit miss goes away.
Each cylinder is logging misfire counts with no rhyme or reason. The only thing odd during the timing job was 4 spark plugs were partially loose.
I'm sure the timing is correct; I used the OTC crank tool and for timing kit. Truck has 150k, front 02s are fairly new...

So working on a 2005 F150 with a 5.4. Started off as a phaser replacement. Turn out the passenger side timing chain guide was badly damaged. Front timing chain cover came off and replaced the guide and phaser. Got everything back together and it ran rough. Pulled the front timing cover off and the passenger side was off a tooth.
Retimed that passenger side and also replaced the tensioner because the seal on the old tensioner wasn't the best. Now rotating the engine, i noticed the tensioner pushes then retracts. Seems like a vacuum is created pulling the plunger in, but not entirely sure. Only the passenger side does this, not the drivers side.
Worried about putting the front cover and valve covers on, buttoning everything together and having it skip another tooth because of slack in the chain. Any fix for it or reason why it does it?

I recently replaced a timing belt in a 2003 ALH TDI & since it will not start. When I took everything apart I found the belt extremely worn & the engine had actually slightly jumped timing. When I replaced the pulleys & belt & reset the timing to the way it would be from factory. When I tried to start the vehicle it turns over fine but will not catch. I double checked all the timing, fuel pump, everything - all okay. I can get it running with ether but will not start with diesel fuel. I also replaced the fuel filter, checked to make sure there was fuel at the injection pump but nothing works.

So about six months ago I bought a used 2010 mkvi gti from a small dealer. Now here's my problem. The other day i started my car and it was a rough start. And the car ran rough. I stalled twice trying to back up. Then the car threw a light. I didnt drive it at all. Shut it off and left it. Read the code that night. P0016
Now I know the timing tensioner thing has been beaten to death. So that's my first thought. However, there was never a rattle or a noise. Nothing like that. Is it possible? All four cylinders have compression. About 210psi. I don't know if that is good or bad. Plugs are worn but look good enough. Not too much junk on them. Coil packs look "newer" and they are the "upgraded" versions. Other than the tensioner what else could cause a p0016 failt?

Looking for info if the R32 has a timing belt or is it a chain and at how many kilometers shows it be changed.

I hear it's a problem on the Mk VI. Is there anything you can do or upgrade to eliminate the problem ... especially considering that it goes out of warranty after 5 years.

I was thinking about checking out the above vehicle at my local dealer (Chevrolet). They're asking 15.9k and it has 57k miles. I need to know if it has a timing belt or a timing chain and how reliable is the engine/transmission.
