      From what I have read on vortex it is the upper guides that go first. I'm wondering if the issue was engineered out with newer parts.

      Is this only a 05.5 - 06 Jetta issue? What about the 2006 Rabbit? Has anyone had problems with this model? Just wondering because I have an aging 2006 Rabbit and would like to avoid something like this. Thanks!

      From what I have read it is an issue with the first 2.5l engine and was engineered out in 07 I believe. I am in the same boat as you, I want to fix it before something happens.

      I do beleive it affects the rabbit too, but I am really not sure.

      Are you sure? The upper guides are what goes first on VR6s, especially early VRs, but I thought it was a sprocket that wears on the 2.5L, causing chain stretch.

      Reporting to VW is the best chance of getting some immediate help with your car. The best thing that could happen for 2.5 owners is for everyone with a timing chain issue is to report it to NHSTA.

      vortex member VW Redux had a DSG transmission fail at just over 600 miles. Search for his posts to read about what he did. His reporting to NHSTA resulted in a government campaign as well as one by VW resulting in hundreds of people (if not more) getting repair reimbursements and causing VW warranty the DSG to 100k miles.

      I have gotten the famous problem with my 2.5-05 engine at 93K. However, when the CEL came on, I was already too late.

      The transmission needs to come off to replace everything, so that is something you need to consider paying for. In most cases, if not all, the engine needs to come out to replace the chains. I ended up buying a new motor and replace it myself due to the cost involved.

      I agree that the timing problem should have been a warranty issue, but VW knows it cost a lot of money to replace that.

      Is there something I can do before its too late??? Will replacing both tensioners, guides, and chain solve the issue? Should I replace the gears too?

      Like it was said earlier... it is a pretty big job... drop the trans etc. I don't know if that will solve everything but it is a shot lol.

      Hopefully this doesn't happen to me. But I will be changing out my clutch, so while i'm doing that I may spend the extra afternoon changing that stuff out.

      From what I have heard and read, the gears or sprockets are not set at the right torque, which eventually creates the jump of the chain. A dealership as well as those like myself had to take the engine out to either replace the parts so yes, it is a big job.

      Find out from your mechanic how far he has to go to replace the waterpump and go from there.

      Yeah, if this ever happens to me I would just swap an 08+ engine.

      Lot of good info.
      "Since the only real problem was that the worn timing chain sprocket allowed the timing chain to "slip 3 teeth", replacement of the worn sprocket, timing chain, and timing chain tensioner and guide components should have been all that was required."

      Thank you to Ecs Tuning,

      You will need a timing chain kit, ES285903 (adjuster), ES285925 (gear) in order to correct the issue BEFORE it beomes a major problem.

      Just wondering if anyone actually had their timing chains, guides, tensioner pre-emptively replaced! If so how much did it cost you? I'm also thinking of replacing my timing chain etc before i fall victim to this manufacturer defect. Another difficult thing i've encountered is finding someone who is willing todo the work. Any reputable vw mechanic i go to tell me that i shouldn't worry about the timing chain til i get closer to 200,000kms which i think is about 160-180 miles but in my opinion i think they're guaging this based on their experiences with MKV VR6 dual chain set up. Anyways if you've gotten the work done pre-emptively then please post how much you paid all in all for us who are interested in going that route as well.

      I am in the same boat as you. I priced the parts at ecstuning, looking at a little over $700 in parts. I have 83,000 miles on my motor, I am going to send out a sample of my oil to get checked out and take it from there. I am just going to go the route of driving my car till the pistons kiss the valves, then find an newer motor/ecu and get that installed.

      $700 in new parts eh? I got my 17K '08 engine for $1,000. I guess it depends a lot on how long you want to drive your car or trade it in when that happens.

      VW of America is aware of this problem (although they don't claim that), and will give you a $1,500 voucher towards a new Jetta.

      If you have a 2007, why would you do this? From all I've seen, the issue only affects certain '05.5-'06 cars.

      Btw, the guy who made this website fails to mention what car and engine this is, but that is a 24v VR6, not a 2.5l five-cylinder.

      I was on the phone with vwoa for 45 mins, got absolutely nowhere, not even a voucher. I talked to the supervisor who informed me that there is no known issue and there was nothing they could do.

      "Check carefully before purchasing a Volkswagen with a chain driven overhead camshaft engine - and this includes almost all VW engines, and some Audi engines. I am relating my experience here to alert others to the problem."

      This guys situation in very similar to the 2.5l issue, good catch on the picture.

      I'm just going to drive my 2.5 till it goes, then put a newer 2.5 in it, cheaper than buying a new car or buying a used one, I like the mk5 jetta over the mk6, although I havent driven or been inside one. By that time I may have extra money and possibly put a turbo kit on

      The bolded part is not true. All the four-cylinder engines, except for the TSI, have belt-driven overhead cams. Not to mention that the non-hardened sprocket issue seems to have only affected a small batch of parts on certain engines.

      I'm not going to argue with you over some article that I posted to inform others with this issue. You are right... I'm going for a long walk over a tall cliff.

      I would be extremely relieved if it truly affected only the 2005.5-06, but unfortunately i've got nothing but mixed reviews. Some say that it only affects those model years, then some say it affects the BGP/BGQ motors, and then others say that it affects the 2005.5-early 07 models. But so far, knock on wood, i've only seen this happen to the 05.5-06 models.

      I was just pointing out some facts. Not every article you stumble across on the Intarnetwebz is gospel.

      based on what we have seen, the issue only affects the early engines (05.5 and 06s)
