Default P2112 FIX for the uber cheap

This Crapped out at 63000 miles...still going at 108000....and now 135000.


I took this thing apart on my 06 jetta tdi. Stupid plastic gears! I can't believe there is not a recall. About 10% of the black gear was stripped out -(it's a 1/3 of a circle so 20 % of the gear was fine. As I inspected it, it was obvious that the gear could be turned around and the stripped part would never be used...(if I could get it off). NOTE -It's definately a NON-Serviceable part...but I did.

To do this,

Take it off, Clean the intake completely (cleaner the better as you'll be driving this by needle bearings, take off intake flapper (2 torx) remove it, take the black cover off, remove the white gear, drive the assembly with the black gear out by taking a punch and driving out from the other side. drill out the plastic in about (I think) five spots (2 are easy as there is an impression in the plastic. One (I think- its been awhile) is in the center, and the other two are about 1/4 inch from the outer holes. Drill through both sides of the plastic...That's all the way through - note: if you're drilling metal you're in the wrong place! remove gear, flip it around. Use a bonding glue, reassemble it - AND BE SURE TO HAVE THE GEAR PROPERLY SEATED ON THE METAL as there is no tolerance for it. Put it back together, presto. Put 400$ back in your pocket. Mine is still going. :-)

Nothing to add except mine failed about a month after driving the car off the lot. Bad design using a plastic gear that close to the egr and exhaust manifold.

Due to the price of the part and the fact that it didn't seem to have any adverse effect on performance or mileage I left it go. Recently the car has started to perform poorly at 2500 rpm on up. The code is still P2112. Rechecking the price for the Flap at vwparts.com I see that they list the 03G128063J but the price is up to $345.60 as of today. Several posters reference IIRC but I don't know who that is. Please enlighten me as I feel this repair should be handled ASAP on our TDi and I want to get a good price on the replacement part.

You may or may not have noted that I at least attempted to come up with helpful info like part numbers an pricing to save other users trouble.

We are good! I would have used clickable links, but you did fine!

Local dealership at $405 each plus it'll be a 2 day wait since they don't keep them in stock.

1stVWParts at $345.60

No way to do clickable link directly to the part itself 03G128063

Apparently the final letter in the P/N makes a big difference. I had read of a 03G-128-063-D or 03G-128-063-G or 03G-128-063-J or 03G-128-063-Q

From what I have found, the Q is what I need for my 2006 TDi, yours may need a different part as I am old that the -J part is for a BHW diesel as used in a Passat. Sorry for the confusion

The 03G-128-063-Q is available at 1stVWParts at $216.00 plus shipping. Ordered mine today

EASILY THE BEST DEAL I SAW ANYWHERE.

They have fast, professional, service every time I have ordered from them in the past and obviously great prices.

It seems the question has been asked (and answered) several times in this thread alone. It is not a very big thread, please go back and read through it all before posting.

Got my new flap today. With the bad flap off I can see inside the assembly and it is gunked/carboned up big-time. I'd like to clean this out and I think I even saw a thread on here somewhere but searching thru the other threads for quite a while tonight I haven't located it. I think it'd be foolish to spray carb cleaner into the assembly and have chunks go down into the engine (exhaust manifold?). At the same time I was thinking a quick 20 minute swap and I'd be done. I am not sure I can bring myself to just slap it back together seeing that 90,000 miles worth of buildup in there.

Here's a picture

I put the new "flap" in on 8-31-10 and I was under the impression that the ECU would calibrate the system itself just by driving it? The power is a little better with the new flap but in a word performance is "flat". We took our TDi in for a timing belt job today. The owner of the shop called and said that there were "adaptation codes" that were needed to do a sort of calibration when a new part like this is installed. He has a Vag-Com tool obviously but said that some of the guys he talked to about this said you had to take it back to the stealership to get this "adaptation" done. Anyone have access to these codes or have any knowledge of this? Our mechanic was looking to source the codes so he would have them for our job and then retain them for future use as well. Thanks
