• The TDIClub classifieds section is a heavily trafficked section of the forum that encompasses want-to-buy (WTB) and for-sale (FS) threads for the entire world. Due to the demanding nature and fast pace of this section, it is imperative that you know and understand the rules. It is also important to remember that this is the only parts classifieds section.

    Cross-posting and posting classifieds in the regional sections (except the dedicated thread in Ontario) is not permitted.

    Multiple items should be sold in one thread. Make sure to provide a description for all items in your post along with pictures and prices. If you start multiple threads with individual items, they will be locked or combined at the discretion of the moderators.

    Here is a quick outline of the classifieds section rules. If you don't follow these rules, you subject yourself to thread deletion, thread combination, infractions, or posting privilege revocation.

    Thread titles:
    • Put FS or WTB in your thread title. This will let other users know if you are selling or buying.
    • Briefly describe what you are selling. Thread titles have limited space. Be as descriptive, yet succinct, as possible.
    • Put your location in the title.
    • If space allows, put your price in the title

    Title example (single item): "FS: 2004 Mk4/BEW cylinder head - Portland, OR - $500"
    Title example (multiple items): "FS: MK6 fog lights, front bumper, headlights, grill - Detroit, MI"
    Title example (car part-out): "FS: Mk3 Jetta parting out engine & interior - Dallas, TX"

    Thread text descriptions and pictures:
    • All for-sale threads must include pictures of the items that you are selling. One picture is sufficient, but multiple pictures with different angles will help buyers. A picture is worth a thousand words. If you don't know how to post pictures on TDIClub, see this thread: http://forums.tdiclub.com/showthread.php?t=286691
    • All for-sale threads must include a description. We don't charge per-word, so be as descriptive as possible. The more information you can provide, the easier it will be for buyers.
    • All for-sale threads must include a price. Auctions and bidding are not allowed. If you want to auction something off, use eBay.
    No picture, no price, NO SALE!

    Thread maintenance/updates/bumps:
    • When you sell something, update your thread with "SOLD!" Moderators will close the thread and update the title.
    • If you have multiple items for sale, update your thread as each item has been sold. When everything has been sold, updated the thread with "ALL ITEMS SOLD!" Moderators will close the thread and update the title when all items have been sold.
    • If you bump your thread, please delete old bumps by clicking on EDIT and then deleting the old bump. This will reduce clutter in your thread and make it easier to read. It also makes you look less desperate.
    • If you drop your price, please update your first post in addition to posting the new price. If you would like the thread title changed, click on the report post icon and let a moderator know what you would like the title changed to.

    Moderator intervention and infraction points:
    Moderators will be monitoring the classifieds section. If a moderator determines that you have not been following the rules listed above, corrections will be made and infraction points will be assessed to your account.

    What is an infraction point? Simple - it's a system of keeping track of user behavior. A moderator can assign a point value based on the severity of the infraction, as well as an expiration date on the points assessed. If you accumulate a certain number of points, the system will auto-ban you for a predefined amount of time. The more points you accumulate, the longer your ban period will be.

    One example of points is as follows: multiple threads will be combined into a single thread, with the number of infraction points assessed corresponding to the number of threads merged. If we merge four threads into one, then you will be assessed four points that expire in 30 days. When you reach five points, the system will auto-ban you for one day.*

    *This is an example based on the current infraction system structure. We reserve the right to modify the infraction system at any time without notice or updates to this announcement.

    Thank you for your cooperation, and good luck with your sales and searches! :)

none at the moment
I ordered one of these and I realized I already had one. Brain fart I suppose. This is the socket you need for the security bolt on the fuel injection pump. Cost was $27.85 shipped to me so I'll take just the cost of the part and pay for the shipping: $23.00 Thanks.

Now, all I have to do is take a drive into the redwoods pay for it, and pick it up. Nice place you at up there.

Thanks

After I find the jerk that put that security bolt on that pump, and have a conversation about how to engineer things with some intelligence. Does anyone know where to get the security socket for a 2001 tdi. It is not a triangle bolt I have that set.

Well I would but right now it looks like a 5/16 cheap Chinese socket with JB Weld inside, when I get that out it will be a bolt like the other three torques. I would have it out now but the wind is blowing dust all over and I don’t want that in my pump. It occurs to me that I never noticed that security bolt in over 300,000 miles, makes you wonder why it would exist at all!

Well, you were not here during those 300k miles or you would have learned about it long ago...

You need to make sure you are well versed on what takes place when you loosen all those bolts. Example: The top of the pump will move ever so slightly and the result is the injection quantity will be affected.

I understand injection pumps, and my vagcom will allow me to get back to 2.9 volts. The problem as I see it has been the move to plant based diesel which just runs right through the old gaskets. This was the first tank I had ever used as I have been careful not to use biodiesel. Now it’s mandatory here. Honestly this is the first time I have needed your guys support, and I appreciate that support. I am an aerospace engineer, and would never design a trap like this!

When I needed to get the triangle head bolt out, and did not have the appropriate tool, I took a 7.5mm socket from a cheapo socket set, and with a solid tap to the socket the bolt came right out.

Or Dremel a slot in it and use a screwdriver. Then get yourself an Allen head bolt of appropriate length and never have to deal with it again.

I used the jbweld and did exactly that the new bolt cost $3. It took me almost 3 minutes to replace The gaskets, pump fuel in it. Then maybe 5 minutes to get it running smothly and within parameters. The only purpose for that bolt was to frustrate people into taking the bug to a shop for overpriced repairs. Personally I hate engineers who would do something as unscrupulous as this!

Well...if 'mechanics' do not have an idea that you can either create a run-away engine or immobilize the car by messing with this pump section it may be somewhat of a good deterrent. Maybe then they will look into why there is a security screw before they start messing with it.
I am working on a PD Passat now where the owner could not get it started. He removed the solenoids on not only the injectors in his car but a spare engine's as well thinking that he would swap what he thought was the injectors from one engine to the other. He wound up ruining all 8 injectors which will cost big bucks to make good again. It would have paid to have some sort of tamper-proof security device on those. It wound up that the original problem was that the cam timing was a little bit off. Had to buy another set of injectors that weren't messed with. That was an expensive mistake.

Joe,


If you thought that was bad, the next leaks on the pump head seals are going to really torque your shorts. Just sayin.

JETaah, reminds me of Fuel Filter changing on these engines. I'm sure you've seen it too. Seems anytime there's a slow start, seemingly a hard start, no start, loss of fuel economy, etc., the go to thing is to change the Fuel Filter. And, many of those Fuel Filter changes ended botched. Then, they had another problem and never knew it.

My first VW Diesel was a 1980 Rabbit that I purchased in January, 1980............ 41 years ago. After about the third or fourth time of "draining" the fuel filter to clear the water, as a preemptive thingy, I quit the practice because the amount of water was either zero or a drop or two. Of the 2 million miles I've driven in my lifetime, I cannot definitively say that I've ever had a water in fuel issue.

I've told this story numerous times. My brother never changed the Fuel Filter on his 01 Jetta TDI until just slightly over 171k miles. Yes, 171k miles with zero issues!

You could never get away with that on a PD car. With the level of engine byproducts (not water) that wind up in the fuel tank from the fuel return circuit it can make 20K miles almost a borderline interval.

Yeah, JETaah, I agree with respect to the PD engines. I've replaced a few in-tank fuel pumps and seen the black mess!
