    Default When going to look at a TDI what should I look for?

    Found what looks to be a pretty solid TDI on craigslist. I've never owned a TDI, but with college, work, and extra driving my VR is killing me on gas! So as the title states, what should I look for?

    Thanks in advance

    Generally, a tdi badge on the back is what I look for

    Timing belt maintenance. 3 pedals under the steering wheel. a tach that doesn't go nearly as high as your GTI. If it's an MK4, that it still has the crayon smell.

    otherwise, normal car things- rust, fluid leaks, uneven tire wear, suspension upgrades/modifications, clean non-smoking PO, dashlights, etc.

    Need some more details as every platform is different and there were two different engines used in the MKIV platform. How many miles on this car? What year? Cars with 200k+ miles have a lot more to look into.

    I like to look for any 'crappy owner' mods under the hood like hacked wiring, ghetto hoses or any 'shiny new' parts that don't match the rest of the dirt factor on the engine.

    Other than that, run it through its paces. It should accelerate smooth with little to no smoke. No limp mode and no codes should be present.

    Timing belt maintenance specifics:
    • Mileage completed?
    • Parts used (lots of novice people skip parts or one-time use bolts that are critical replacement parts)
    • Who did the maintenance? Trustworthy?

    yeah, mkIII? MKIV? MKV? MKVI? Pumpadeuce? common rail? just get something with good records and you'll be fine.

    From Florida no rust
    new brakes
    new front axles
    new starter
    Says there is 50 miles on the motor? Assuming it rolled over 299,999 and the tach reset itself causing this mileage

    For me show stoppers on a tdi are in this order:

    1) Has anyone ever burned WVO in it? Look in the trunk, smell around for putrid smells, inspect for any additional holes around the spare tire, etc for fuel lines to pass through. If you were so inclined you can very easily remove the top cover of the pump to inspect for any rust or buildup of crap that comes from running that...crap.
    2) Timing belt (as already mentioned). Who, what, when? If you don't get satisfactory answers to these questions I'd pull the valve cover and inspect for domed or cracked lifters. If you see this then you're in for at least a $1200 repair (parts) as soon as you take ownership.
    3) Rust (for your mk3). Check everywhere typical for this generation. Cars rust in FL too...just depends on where the car lived.
    4) auto trans (not an issue for a3/b4 tdi's but wanted to mention nonetheless). Not a show stopper but I seriously detract on price if the car is equipped with one. Auto > manual swap is easy enough but isn't free.
    5) Injection pump. OEM or not? If not beware....lots of prothe (Roethenbacker engineeering) pumps running around. They are crap (as are all his parts) and will need to replaced.

    That's about it. Might have missed some items but these are the major ones that come to mind right now. That AHU is a pretty fun car with a minor tune and injectors. Turbo comes on line RIGHT NOW but the engine generally runs out of breath much sooner than the later TDIs.

    Nope. MKIII rolls over at 299,999 and the word 'Total' disappears from the odometer display. The MKIV Jetta/Golf cluster just stops at 621,371 miles or something like that. New Beetle cluster goes to 999,999 (I think).

    Is the fuel economy really worth getting into yet another VW you know nothing about?
    I'm honestly not trying to be mean, but you had so much trouble with your 8v mkIII (insanely easy to work on) why do you think you can handle the TDI?

    Also, you're talking about mileage when your FS add for the mk4 says you'd take another vr6. A 12v is a 12v is a 12v man, they're all going to get similar MPGs unless you put it into a much lighter body, like a mk2. Granted, the mk3 vr will get better mpgs than the 4, but only slightly.

    You want MPGs, get yourself a DOCH 4 cylinder (somebody here is selling an escort...) and drive it like a grandma. 35mpg all day long.

    I would recomend getting back into an 8v, run 91 or better, open up the intake and exhaust just a little, drive slowly and you'll pull 33mpg highway everyday. My golf averages 30, and I beat the piss out of it.

    I think it's a good learning opportunity for you. I wish I knew more about TDIs. (and I have one).

    although, for learning purposes, maybe momo did/does it best- I'm not sure he's ever sold a car yet. He keeps buying them though

    I will say this though, once you find a chassis you love, you keep longing for a same replacement.

    I second the buying a TDI to save money is a little crazy when you already have a car that I presume is paid for. How much 91octane can you buy and burn in your VR for the $4K of a new car? Plus diesel is like totally, way more expensiver than gas, dawg.

    if I HAD to buy a car to save money and fuel I would look for the cleanest, rust free Toyota Tercel I could find. And I love TDIs
