Tiguan :: Timing Chain Tensioner Causing Catastrophic Failure
Sep 12, 2014
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.

I 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 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.

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.

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.

Got 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] ......

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?

My 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?

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!

Replacing 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.

I have a 2009 Tiguan 2.0t 4 motion and recently has started having a very high pitched squealing noise coming from either the accessory belt area or the timing chain. The noise is constant until you are under acceleration and then it goes away. The CEL came on but when scanned it said no codes. and now sometimes the CEL will flash and the car has been idling rough. What it may be?

Last week i took my '04 V10 in for tires/brakes/rotors with a local service shop. The next day they called saying one of the service attendants must have left the keys in the car overnight, because the battery isn't working right.Here is what happens (all within about 15 seconds)
1. Put key in ignition, engine starts normally
2. Multiple error lights immediately start flashing (engine, glow plug,tire pressure, etc, etc...
3. The MFI screen goes black (like the Tony Soprano finale)
4. the center console flashes "safe ..........." for a split second then goes blank as well.
5. the a/c does not run at all during this
6. the engine RPMs will not increase despite pressing on the accelerator.
7. the engine suddenly stops.
8. everything is then dead on the car.
This all takes place over about 10-15 seconds. This entire process can be reproduced by taking the key out and starting over. They are shipping the car out to a dealer for further evaluation, their computer gave them some sort of "battery learning error", but they were unable to reset it. I haven't heard of a dead battery behaving like this. The Touareg never ceases to amaze

Ok so I've had this problem since I bought the truck and has never really caused any damage anywhere except in the rain and snow it makes it brake loose much easier. i bought the truck at 90,000 and im at 217000 now. I just recently added a programmer and bored it out and now I am concerned the extra power will cause catastrophic failure, i found this which accurately describes it as to what the problem is? my 92 f-250 felt this way when the driveshaft was getting loose but no such problem on this one.

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.

My girlfriend owns a '92 Plymouth Acclaim. We noticed a few weeks ago that there was a clunk/rattle noise coming from one wheel, and since it mostly happened while cornering, thought it might be CV joints or maybe suspension. She brought it to her mechanic who inspected the brakes and found that the rear shocks were bad, but sent her away without fixing anything. The other day, on a long drive, the rattle suddenly intensified, morphed into a loud grinding noise, and then the wheel fell off.
I think I'm going to have to confront the mechanic. The bearings apparently hadn't been repacked in some time, and were surely the cause of the rattle noise. I'm less concerned with the fact that he might have overlooked an obvious problem as much as neglected to properly service the vehicle.
Are brake techs supposed to check, then tighten wheel bearings or repack them if needed?

I brought my 2004 VW Touareg V6(83k miles) to the dealer for a recall on the ignition call and much to my surprise, was presented with a diagnosis of a $6,000 problem! The dealer told me that the computer read some codes which say that the timing chain is stretched and needs to be replaced. They said it will take 4-5 days and should be done asap so it doesn't "go out", because if it does, it's an even more expensive problem. I took the car to another VW repair shop and they asked me if I heard any noised when I start it cold (like pebbles in a bucket). I have not had any problems like that at all, so they said I shouldn't worry until I start getting symptoms. They also said there is no recommended point (like 90,000 miles) when VW recommends the change, so it really shouldn't be a common problem. I want to do the right thing, but I don't want to rush into an expensive repair if it isn't necessary.
