    Hey all, I just bought a 2005 Passat TDI with 126,000 miles. I know this question has probably been asked way to many times, but I have no idea if the timing belt was replaced or not. I have looked at Chittychittybangbangs replacement guide and the belt he replaced didn't look all that bad, but the the pictures were kind of small. I don't think my belt looks horrible but I have absolutely zero experience with these things and was wondering if you guys could look at these pictures and give me an idea on how many miles this belt has on it.

    Hopefully these pictures show you guys enough. Thanks in advance.

    looks normal to me, I don't think there's a 2005 passat tdi timign belt guide anywhere, if that's the orignal belt get it replaced ASAP since you're way overdue!

    Yes, I have not seen any passat TDI timing belt replacement article anywhere. Your engine is different than the one shown in the article. It does not apply to you.
    Edit: there is now one that can be found here: http://www.myturbodiesel.com/1000q_how_to/b5/bhw_timingbelt_1.htm

    There is no way to tell if a belt is good or not unless there is some obvoius failure. Unless it's brand new, there is no way to tell how many miles are on it. The way they normally fail is a single tooth breaks off and that's the end of the valves. It's very rare to have it actually split and snap. Other failures are because a pulley or roller seizes and causes the belt to snap.

    The timing belt change interval for your 2005 Passat BHW engine is before every 100,000 miles. I don't want to scare you but look through the maintenance log or receipts, ask the previous owner(s) to figure out if the timing belt has ever been changed. If not, I would not drive the car except in an urgent situation because if that's 26% over the intended timing belt life. Can it last longer? It's possible but the farther you go over 100,000, on average, the more likely a failure.

    Years ago, my Mitubishi was going to have the timing belt changed on the weekend. It was already overdue and the timing belt broke that week. I learned my lesson fast.

    If I were you: I would have the timing belt changed ASAP along with the water pump and all rollers. You can buy the parts here: http://www.tdiparts.com/catalog/product_info.php?cPath=24_95&products_id=1047 . By this mileage your oil chain may also be making noise. I hate to tell you, but the oil chains on the BHW engine get play and break. If it breaks, it wipes out the engine. The only fix is to replace it with a new oil pump assembly that uses a gear drive to replace the chain assembly.

    An approximate total cost of labor+parts for the timing belt, timing belt labor, oil chain assembly and oil chain assembly labor is about $3000. It's best to have it done all at once since the timing belt has to come off to replace the oil chain assembly.

    Parts can be purchased here: http://www.worldimpex.com//parts/genuine-part-bhw-module-repair-kit-passat-bhw_935619.html or here: https://www.boraparts.com/product_info.php?products_id=270

    I am not aware of any dealer which is familiar with this problem because it's such a rare car and because the updated part is from a European TDI (they fixed the problem in Europe but not in the US because these are rare cars). You could try this mechanic:

    Import Auto Werks
    1823 E Millbrook Rd # 106
    Raleigh, NC 27609
    (919) 871-5850 Chris Dale (eastern NC)

    These guys have already done this repair at least once:
    German Speed Merchants
    300 Old Dairy Rd
    Wilmington, NC 28405
    (910) 791-4844

    It's not an endorsement but these shops have worked on TDIs and German Speed Merchants have already done this repair at least once. Here are instructions from some TDI specialists on another forum, Mogolf and oilhammer, on how to do the replacement: .pdf file . Here are more instructions on this site:http://www.myturbodiesel.com/1000q_how_to/b5/balanceshaft _moduleReplace.htm

    And although the oil chain replacement sounds like a bit much, this failure has hit many people. The explanations I've seen have convinced me that sooner or later, most 2004-2005 Passat TDIs will have this problem, some of which had the problem as low as 50,000 miles. VW even changed the design and stopped stocking the old design (that was found on 2004-2005 Passat) so they were probably aware of the problem...it was almost certainly an honest engineering mistake, the problem is that VW is not acknowleding that there is a problem. Some people who did this replacement just for peace of mind found out afterwards that they were having this problem but thought that it was normal.

    On the bright side, once you do the timing belt you're good for another 100,000 miles...and the oil chain assembly repair is a one time repair. As a side benefit, replacing the chains with gears will quiet the car.

    The $1500 kit from Bora seems like the way to go. I'm just waiting on the dealership now. They are trying to contact the previous owner. Thanks again guys for the help.

    Congrats, I've seen Passat TDI but they are hard to find and expensive. Once you fix this thing it'll be a very reliable car....get a rocketchip tune http://www.rocketchip.com/ and you'll have a real bad car!

    Hey guys, taking my Passat into the shop this coming Monday. I'm getting the Oil pump assembly changed out, a new timing belt, and a new water pump. I also asked them to change out the glow plugs and put in new motor mounts. Anything else to have done while they have her all torn apart?

    I am going to:

    German Speed Merchants
    300 Old Dairy Rd
    Wilmington, NC 28405

    I just looked over the estimate and what they charge for parts is right in the ballpark of what you would spend if you purchased them yourself. They quoted me at just under $3600 for everything; timing belt, oil pump assembly, motor mounts & glow plugs. Labor comes in at $85/hour for 14.5 hrs. So far they have been real helpful and seem very knowledgeable. I will let you all know how it goes.

    Got the car back tonight. So far everything is looking good. The estimate was right on, no surprises, and the staff was very friendly and helpful. I would definitely recommend them.
