Hey all, I have a issue with my T2. I was driving it and noticed a light rattle noise. When I stopped it instantly got louder. It has 93k on it and I have only had it since July. I changed the oil and filter earlier that day with Mobile1 ESP 5w-30. Yes, it meets the 507. cert. At idle it's pretty loud but when you rev the engine a little, it gets quieter. I have ruled out the engine except for either the timing chains/tensioner/guide rails, HPFP or ??? Here is a video. Any help would be greatly appreciated.

Thanks, Chris

yes, I used a VW oil filter.

If I hold the engine RPM's above 2500, the noise goes away completely. I also seems to be more on the top or back side of the motor.

Looks like I'm going to have to have it towed somewhere. I don't have much experience with these newer technologies. I just don't want to send it to th dealer.

I spun the filter until I could push it down. Then I put the cap on it. I hope there is only one hole for that peg to go into.

I hear ya. I am hoping it's not a major engine issue. When I put the stethoscope on and checked the noises, it seemed to come from the fuel rails. That is where it was the loudest.

I'd get a new filter and start again.

It's already on its way to the shop.

 

[cdgvw1]

Thanks for all your help. I'll let you know what they tell me. Hopefully today or tomorrow.

I changed the oil. Added the 8.2 L of Mobile1 ESP 5w-30. The filters looked the same and the new one was from VW. The lower o-ring was already on the filter peg and I put the big green one on the cap. It ran fine when I started it and when my wife left with it. I was standing outside the car when she drove off to go home. We were at my friend's house as I was reworking the upper end on his Offroad truck. I'll check the old filter when I go to my buddies tomorrow. It doesn't sound like a rod knock to me. But, i could be wrong. There also no cel or any other warning lights on. Sucks that there isn't an oil pressure gauge in it.

Turns out it is the High Pressure fuel pump and VWOA is covering it under the extended warranty which is good for either 10 years from the date in service or 120,000 miles whichever comes first. Just make sure the correct fuel was used and no mods to the car. It is a huge relief. It is going to the VW Dealer to get fixed.

Side note, my Treg is on the Emisions issues list so we'll see what happens with it in the long run. Call VWOA and give them your VIN to check for these types of warranties and emissions issues.

Thanks, Chris

Well, good news, I guess, the HPFP is not the problem . Bad news is the dealer is thinking the exhaust cam slipped time with the intake cam. I don't see how the engine can be as smooth as it is with this problem. I guess I'll find out in the next couple of days.

 

[cdgvw1]

I think it's the tensioner as in this video, I can rotate the HPFP cog gear a little back and hear an audible chain slack noise from the back of the engine and the P/S pump pulley doesn't turn with it. I didn't like the route VW was going with it so I trailered it home. I am going to re-change the oil to the OE Castrol with another new VW filter and go from there. Does anybody know the serial number cutoff of when these engines received the updated tensioner?

Found the problem. After dealing with the dealer, I took it home, removed the Aux EGR cooler, removed the upper driver's side timing cover and found a broken Timing chain tensioning rail. It broke where the tensioner piston pushes on the rail. A place where it shouldn't have broke.

 

[cdgvw1]

#37 shows how the tensioning rail should look.

 

[cdgvw1]

Well, like usual, VWoA says I am on my own as there is no current campaign for this issue. I find it odd that the part that broke is different than the new replacement part. Different material and stronger design in the area that broke. In conversation with a VWoA rep, they told my just because the part is different, it doesn't mean it was a problem. I call BS. No manufacturer will spend/waste the money and time to R&D a new part design for no reason. Very disappointed in VW.

 

[cdgvw1]

I am trying. They keep telling me its not under warranty and there are no current campaigns for it. I told them well, you need to escalate this to your campaign department and get one going because I am pretty sure I'm not the only one. I know why it broke. There is too much stress on it from the HPFP.

 

[cdgvw1]

The dealer wanted $5,500 and an independent wanted $3,000 plus parts to pull the engine/trans. I don't have that kind of money. I was able to pull the Aux EGR cooler, because it needed 2 (dumb), and was able to replace the parts, but there is one piece that I couldn't find which sucks. So know I need to try to hang the engine, drop the sub-frame, pull the trans and timing cover to find it or send it to a shop.


Thanks for the heads up on the part numbers. I didn't know that.


I guess I'll send emails once or twice a week and hound VWoA and try to annoy them enough to get this fixed.

 

[cdgvw1]

No, just the driver's side that runs the HPFP off the intake camshaft. This is the same side that had problems with the 2.7L TDI and possible early 3.0L TDI's, which use the same fuel pump system, that the tensioner for this side was redesigned to what I currently have, which still failed.

 

[cdgvw1]

Sorry to hear. Did you report it to VWoA yet? I would definitely take the time to help to make this an extended warranty campaign and possibly get reimbursed. Make sure you keep your old parts. How many miles on your rig?

 

[cdgvw1]

I didn't realize you had yours at the dealer. I would put pressure on the rep for that dealer and show them my pics and make sure you see all parts new and old and try to get it warrantied if it is the same problem. This is something we shouldn't have to pay for. It is a design flaw and should be taken care of by VW. If they wont budge, call VWoA and get a paper trail started. Send them pics and you can refer my name so they can't tell you yours is the only one to have this problem..
