Hello all. I am new to this forum. I have an '06 JEtta TDI with the BRM engine (128,000 miles). I'm getting a fairly loud report back through the intake manifold. It can be heard at idle and gets significantly louder under hard acceleration. Removed the anti-shudder valve and EGR sections from the intake manifold to isolate the source of the noise, and it is definitely coming back up the intake manifold. Removed valve cover to look at cam and lifters. Without removing them, they appear to be in pretty good shape with no deforming of the lobes or the lifter tops. I've ordered tools from Metalnerd to check for timing belt alignment. Would a one tooth misalignment cause the valve train to crash into the pistons or would it just run poorly? A compression check through the glow plug ports revealed 455, 440, 450, 460 psi on the cylinders. Any help would be appreciated.

The car can still run if it's off a TB tooth but not well. Why would it be off unless you removed the belt? Is the TB original? at 128,000 miles an original belt would be way overdue.

An exhaust leak might cause that sound. The exhaust manifold and EGR tubes are right below the intake manifold.

Similar issue

I don't have an answer for you but I have what seems to be an identical issue with my 06' Jetta Tdi 1.9l. It has 118,000 miles on it and I changed the TB myself at 111,000 miles it's run great up until about a week ago, at first it sounded like a simple exhaust leak but after some invasive investigation that checked out and there was no leak, so I pulled the cover off the air filter and found my noise. I traced it back to where the intercooler air enters the intake on the passengers side of the motor. My schucks orielly OBD2 scan tool shows a DTC" diagnostics trouble shooting code" of PO101 which is mass or volume air flow circuit range/ performance, this is a code that came from the intercooler sensor because of the exhaust coming fromthe intake. I can't solve your problem but maybe we can work together and get something figured out.

Also I pulled the covers and inner wheel well to access my timing belt to check if that was the issue, and it is not, everything is fine with the TB and pulleys. The TB is on mark and timing perfect.

Some basic things to check: boost leak and camshaft condition. There are articles in the FAQ on how to do this.

So I ended up pulling the oil pan and found some metal, so I then pulled the valve cover and an lifters and found that my cam wore a hole in one of my lifters causing it to fail, next I suppose is to pull the head to check valves and pistons ugh, thats a bummer. A new head from vw is $3750. I'll replace the motor if it needs a head

I just had a new head installed. I picked it up new from Parts Place for VW for just over $2000. Includes valves, cam, etc. Practically plug and play 3 days later.

This is a fantastic price given that fact that a cam kit by itself is 600-1100 depending on cam.

Same Engine issue

I don't have an answer for you but I am have the same symptoms with my 06 TDI jetta.From what i have read on many posts & forms it seems to be a Bad Cam shaft and lifters.Question I have is: is it worth paying $1100.00 for the Camshaft kit with OEM parts or is the Aftermarket kits for $750.00 ok to install?
