    1999 VW New Beetle TDI:

    Cut out three times recently on the freeway for just a split second.

    Today cut out twice in town, completely. But restarted after a few minutes.

    Besides overhauling the manufacturers mom, what can I do?

    Fuel filter. My 2006 would cut for brief moments under full-load throttle at one point. Changed the filter and not since.

    Air in the fuel after cracking the T fitting while changing the fuel filter.

    could be bad fuel... did you recently refill at a station you don't normally use? my family had a '99tdi and ended up having to have it towed and the tank drained because of a similar symptom to yours. the car finally just straight up died and wouldn't restart. the problem turned out to be bad fuel from a shitty gas station.

    another thing to look in to is how dirty the intercooler and charge piping is. ours had to be cleaned every few years due to oil vapors/sludge/whatever building up in the intercooler and piping. in the end we had to completely tear apart the charge piping and clean it all out due to it getting partially clogged.

    H'mm? Should be good fuel, same station for over a year.

    TDI forum says 109 relay (fuel pump power)

    I ordered two from iDparts.com $12 a piece. As iirc this is an ongoing problem since the VW Rabbit days. Carry a spare.

    The Mrs Tucker is out in the car now, I do hope she gets home! It quit on her twice!

    Oh yea, they can be problematic.

    I've replaced all wheel bearings and both transaxles.

    The electric fuel flap doesn't work.

    The electric windows are getting slow.

    The running lights now don't work.

    I don't care for the 'screw in' brake caliper pistons, it's a special tool to change brake pads.

    The electrical system in general on this New Beetle is third rate, very cheap and clunky door locks.

    The underpan cardboard engine cover is crap.

    it does 48 mpg constantly though and runs like a striped ape.

    Diesels and cars with direct injection need a closed crankcase ventilation filter. There are vapors that condense in the intake tract and then set up, they can plug it. Gasoline port injection the additives in the gas take care of this. Diesel and direct injected gas have dry intake, and the stuff really builds up. You will need to clean the filter every oil change.

    Interesting comment on the PCV filter. I just bought a car with direct injection and a turbo (Mazdaspeed3) and was thinking about something like a Mann/Provent filter for the PCV. Thing is, those are kind of large, and there's not much room under the hood because Mazda put lots of bits in plastic boxes under the hood, and because of the giant intercooler sitting on top of the engine. Looks like it'll be a pain to work on, but good gawd the Speed3 is just bonkers!

    Back to the OP's issue though. I used to have a '96 Jetta GLX. It cut out for a split second every once in a great while...never found the cause, but I always suspected a loose/corroded electrical connection somewhere. Might be worthwhile to check every wire and cable to see that they are connected snugly and that the connectors are clean.

    Well the Mrs got home. I'm going to check all the connections and when the 109 relay comes I'll replace that and keep a spare in the glove box.
    I have a bad feeling it's going to stop and not start at all, probably on a cold rainy night whilst we are running to the hospital to visit our daughter having her baby!

    They are available in diesel, but I think I'd like the turbo gasser better. Love engines with hair dryers!

    The turbo gasser must really scoot 'cause the diesel is no slouch.

    We are all about fuel mileage now.

    I sure would like the versatility of a TDI Jetta wagon though, not much room for Home Depot/Lowes trips in the Bug. Plus my Bug was made in Pueblo Mexico on a budget.

    TDI wagons are really nice vehicles...a great combo of utility, comfort, economy, and good handling. I'd have bought one a few months ago but the center console put my right leg in a position that aggravated a medical issue I have. Too bad...it is a great vehicle, even though it sips the fuel of satan. ;-)
