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.
View 12 RepliesI have an '09 Tiguan that recently began to start hard. Two days ago, it refused to start and hasn't started since. It cranks and cranks but to no avail. I disconnected the fuel line at the first hard piece on the front side of the head. The primer pump when activated pours gas out of the line for about 5-8 seconds.
I also pulled the coil packs off and verified there is spark on them. I scanned the car with vcds and came up with nothing other than a couple voltage codes (battery is low at this point from cranking and is bulged and showing yellow in the spot window).
Tonight I borrowed the perfectly fine battery from my B6 and attempted to start it. No codes whatsoever and yet it still refused to run.
I have been reading about all these horrific cases about the tensioner just giving and causing catastrophic failure. Without all the maintenance records VWoA is reluctant to support 100% even if you're still within the powertrain warranty. I understand these 20+ cases are a small population out of the entire group, but I don't want to risk being another statistical point for this topic. Just ordered the HS Tuning kit and the two snap on tools.
View 7 RepliesWhat 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.
On Feb 2015 I had this oil leak developing around the timing chain cover/ oil pressure plug and so i replaced the oil pressure sensor and clean the area and though problem solved...
Fast forward today and the weeping has redeveloped and has gotten larger than last time , its only a weeping issue no visible oil droplet leaks, anyways I took a mirror and when probing around and found the leak origin from the rusty looking timing chain tensioner...that what i think it is.
My question is should I just remove and replace the Rubber O-ring on it or should I just replace the entire timing tensioner unit with a new one, my original timing chain tensioner is sitting at 85k miles. The O-ring is free (i have a kit) and i can do it right now or a New Timing chain tensioner w/ new O-ring is around $20 bucks but i cannot verify the part number ...
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.
View 7 RepliesGot an oil change yesterday and the dealer noticed a small oil leak from the timing cover on my '10 Corolla w/ 71k. Of course they could reseal it for $450. After further investigation, it looks like it is actually coming from the timing chain tensioner. I have seen on the 9th gen this is a common issue, but I haven't really seen anything on the 10th gen. Sometimes, I have noticed a short squeal or squall at cold startup, but it hasn't been enough to really diagnose. It could be some oil on the belt or something else related to this issue. Hopefully the pictures show up.... [URL] ......

View 10 RepliesI 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?
View 1 RepliesYesterday i went to mechanic and changed Timing chain tensioners, with chains and all guides. But still have 2 second voice on startup, once oil pressure lights off everything fine. I paid heavy price on parts and labour but very disappointed after hear same noise again today morning which i was listening from one year purchase of this car... Sonata 3.3l v6 ....
View 4 RepliesMy son's 2007 Hyundai Sonata had an engine noise that was eventually diagnosed as bad timing chain tensioners. However, one Hyundai dealer repeatedly denied the problem, so it was 8 months before another Hyundai dealer admitted it and changed the tensioners. A couple of months later, the engine light and oil light were on and he was told he needed a new oil pump. By this time, the warranty had expired and he had to pay for the new oil pump and eventually a new engine. My question is this: Could the failure of the oil pump have had anything to do with the timing chain tensioner problem?
View 19 RepliesCan 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!
View 6 RepliesReplacing the timing chains and tensioners on an SOHC Explorer, only to have the tensioners fail again after only a few thousand miles? I'm a pretty experienced back yard mechanic and have rebuilt several engines over the years with great results, but this one has me stumped. The only part of the instructions I did not do was to remove the valve springs, but everything was lined up as it should have been using the special tools required to set the timing. I really like the truck, but don't know if it's worth fixing if this is just going to happen again.
View 3 RepliesFirst off I have a issue the Timing Belt Tensioner Stud / bolt that holds my tensioner on is stripped and came out with my tensioner. I don't want to risk putting it back into the engine because some one prior to owning my car stripped the nut that holds it in. Where I could get a new one of these bolts. I have a 2000 VW Golf GL with a 2.0l. I've searched high and low on parts sites and cannot figure out where to buy this item.
View 3 RepliesAlright so MK4 vr6 AFP engine. I did the timing chans when I bought the car around 175-180K. Car now has 224K miles on it. A few days ago I started hearing the chains slapping around. Because I didn't want to call it a broken guide just yet for tor the hell of it I took the upper chain tensioner bold out dunked it in oil and pumped it up till it was hard again. Put it back in and drove the car about 130 miles straight. I didn't hear them making any kind if noise. The next day I drove it about 30 miles still no noise. Later in the evening I whent to get gas when I pull in the drive way I noticed they were rattling around again. So the next day I drive it back home (130 miles) and noticed they were even louder especially around 1500-200 rpm.
So I took the tensioner back out and dunked and pumped it up again. It didn't do anything this time chains are still loud. But I noticed when I was pumping the tensioner in thr oil both times the air bubbles weren't coming out of the bleeder hole they were coming from the end around the piston. When I did the chains the first time I got everything from Germanautoparts.com. and I notice that the tensioner they sell isn't genuine vw part the only place I found the actual vw pary is ecs tuning and the stealership. Is it possible I just have a defective tensioner? I really want to get to the bottom of this before I go and pull the motor and find that nothing is broken. Should I just buy the oem tensioner and see if it fixes it first?
Looking for info if the R32 has a timing belt or is it a chain and at how many kilometers shows it be changed.
View 5 RepliesI 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.
View 1 RepliesI would like to know if any of you had issue with is spark cut. Last week my motor begin to do some noise around the timing chain cover (upper). I open the motor and my exhaust camshaft adjuster was defect ...I change it thinking it was the problem, but the noise still there. (i also change the tensioner bolt). It was not a big noise like when a slider is split in half or something like that.
I pull the transmission off today and saw some weird wear on the slider and tensioner but nothing broken. (i will post pics as soon as I can)
The car have 56k miles
So I was installing my head spacer. When i got the head off I noticed the upper two timing chain rails were shot. The tensioner rail has wear marks from the chain and a small crack in it. Is it possible to change these upper two rails without dropping the transmission?
View 5 RepliesI recently had a good amount of work done to my Mk4 R32. Last night on my drive home from the stealership I ended up with a passenger headlight out and a very loud clicking/ticking noise which seems to be coming from the Serpentine belt area. After closer inspection it looks like the tensioner lines are't lined up which means my belt and tensioner need to be replaced? I'm not sure, but I have a video and this picture.
View 7 Replies2001 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...
