    I' ve swapped brighter bulbs into my '97 Subaru and was quite pleased, but I don't know what your VW has to start with. So what I mean is I was able to compare my bulbs to the new ones before I bought them.

    If you mean some of these cheap kits on eBay to "upgrade" to Xenon, etc.---I'm pretty skeptical, as you can run into ECU problems.

    That's the one I used I think!

    Installing higher-wattage bulbs would be a marginal improvement, would significantly reduce the life of the bulbs and has been known to melt the plastic headlight housing.

    The only SURE way to get better nighttime vision is to install the ecode (European) headlight units which are designed for improved nightime vision by way of better-focusing of the light.

    What is this? The car has 95K miles. It runs fine. it does the usual oil burning a quart every 700 miles that VW says it is normal!!.No oil burning is normal to me but since they had some problem making the engines right, they call oil burning normal.

    There is no coolant loss that I can see. the coolant level is constantly where it needs to be. Often water in oil has this sign. The miles are all stop and go and it never gets on the highway. My 2001 E430 gets this foam under the oil cap some times, but I do not notice it to be as bad as Jetta's.

    The oil changes are normal and on time at about 3K miles.

    Thanks,
    Joe

    I am also led to believe that is about "normal". for both gassers, VW's 2.0 and 1.8T. But....

    In contrast, on a 03 Jetta 1.9 TDI pushing 114,000 miles. Oil consumption is at 1/4 to 1/2 qt (8 oz to 16oz) per 20,000 miles. This presents a dilema to going to a 25,000 miles OCI.

    Does one just change it out @ 20,000 miles, i.e. do not add as it (1/4 to 1/2 qt. 8 oz to 16oz) is still in acceptable ranges. Or does one top up and go the extra 5,000 miles.Of late I just top it and go to the full OCI.

    Hard to say if this is normal or a sign of more severe internal oil gelling. You might want to consider removing a valve cover to examine the extent of this problem.

    If the entire valve train is covered in this goop, you have a serious problem. If it's pretty clean in there, then the little bit of foamy stuff is just normal condensation.

    In other words, you can't make a judgment about this issue merely from the oil filler cap. You have to dig deeper.

    Indeed at 100 k miles intervals (check your specific owners manual for each has different requirements) you are for sure due a TB/WP and Vag.Com tune. Part of the procedure is to indeed remove the valve cover. At that time YOU or the technician and or both can do a visual inspection and ...come to conclusions. If you want to take it to a more serious level, you can also do (UOA's) used oil analysis before, during, and/or after you open the engine.

    So for example at 100,000 miles (in addition to the TB/WP R/R and Vag.Com tune) my concerns were three fold: 1. visual camshaft wear 2. intake/egr clogging due to use of NON ULSD fuel 3. Sludge formation. I had swagged before the procedure little to NO camshaft wear 2. slight intake/egr clogging 3. no sludge formation. The news was better than swagged: 1. original tool markings on the camshaft 2. no clogging at all 3. no sludge formation at all.

    If I was so concerned, I would do the UOA BEFORE; so you can see if the spot UOA has predictive value. The subsequent visual inspection will confirm or deny what you and or the technician think or may have projected. My SWAG is no harm no foul. BUT.... if not, remediate and....

    Then I would do one to 2 UOA's AFTER: to check on the trendline.

    I have also read in passing that 2.0 and 1.8T engines are prone to coking (by product is producing sludge)

    So if you dodged the coking (aka sludge build up) bullet and the UOA/s indicates normal wear metals progression, indeed your 700 miles per 1 qt may indeed be normal.

    97 VW jetta 2.0 4banger manual
    When i turn the key i have power and the lights come on but nothing else happens
    New starter, ignition coil, battery, and battery connections, new distributor cap.
    all my fuses seem in working order. When i touch the starter bolts together with a screwdriver the starter teeth turn with a high pitch whine sound but does not turn the engine.
    Ive checked every electrical connetion that i can find and everything seems tight.
    anybody got any suggestions???

    If you have automatic xmission, the shift-lever may "think" it is not in Park.

    If you have manual xmisison, suspect the switch on the clutch pedal "thinks" you do not have the clutch pushed.

    Don't know if you got a answer to your problem yet... but I know exactly what its is
    The wiring harness in the drivers door!!.. if you take off the rubber boot that protects the wires by the door hinges you will find one of more wires that are broken... I had a total of 12, 8 of which the previous owner tried to fix with butt connectors... the wires get wet or move apart and the alarm system arms itself and the window rolls up!!!

    I messed around with the remote to disarm also cause it also locks the doors

    To temp fix it reattach all the broken wires.. and a perminatley fix, replace the whole harness for about 200$
  • I, added engine oil to an 06 Jetta, Diesel engine probably 1/2 quart over full, Air Bag Light came on in Instrument Cluster, will not go off. Could there be a link here?

    My 1998 S 10 developed a major flex-pipe exhaust leak, but before I could fix that, it also began idling very high (sorry, no tach) at all times. Could the exhaust be causing this idle?

    At the risk of sounding condescending:
    Why would you think the two were connected?

    Oil is to the engine what blood is the body.

    Adding more blood to the body would not make your hat not protect you from the rain.

    The airbag light signals that something is amiss with the airbag / passive restraint system in your car.

    A sensor has determined that the airbag might not deploy as it should.

    That should be handled by a professional.

    Since the airbag can be deployed by accident when not needed and cause injury or death.
    Please read your owners manual for precautions.

    Most cars must have the battery disconnected for at least 2 or more minute to make sure the airbag is not deployed while working on any part of the passive restraint system.

    An engine with too much oil may have that oil foam inside the crankcase and therefore cause damage. Remove the excess oil.

    Pray this helps.

    Has the check engine light come on?
    If so go to Autozone and have them read the codes for free.
    The can give you a list of probable causes.

    It may be that the Oxygen sensors are sending a signal to the engine computer sensing a lean or rich mixture. Then the engine is not going to run as smooth as it should. With the exhaust system compromised this surely could happen.

    Or if so equipped an idle air control valve could have become inoperable causing the engine over speed.

    Pray this helps.

    Since too much oil in engine can be VERY bad for the engine, why did you not suck out the extra oil immedeatly?

    I am assuming you are using the oil-sucker method to change your TDIs oil so sucking it out is very easy.
  • I have a one year older model of Jetta and I often get that foam. My dad says its condensation. It's not just a Jetta thing though. I had a truck from the 80's that did that as well. I freaked out the first time I saw that...It looked like an alien from the movie "Aliens" spit into the oil tank neck. You just have to wipe it out.
  • Okay, so...today my timing belt decided to shred itself whilst I was going about 5 mph in a parking lot. I was wondering what it would cost to replace it and also if it might cause any other sort of damage. And any other info...maybe...?
    But...that isn't my only car troubles...
    My car seems to be going through a lot of coolant and oil. I don't know exactly what the normal usage is for a 2000 Jetta 2.0L, but yeah.
  • jeffyscottjeffyscott Posts: 3,855
    It is an interference engine, so you likely have major damage to the engine.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,404
    Well you can't tell if you had damage until you replace the belt, (since you can't do a compression test without a belt) at which time you might have to do everything all over again and pull the cylinder head off.

    Since you're losing oil and coolant, and since it's a Jetta, I think before I replaced the belt, I'd pressurize the cooling system and check for head gasket leaks, and also remove the valve cover and possibly the oil pan and check for engine sludge.

    No sense putting new parts on a bad engine. You need to start digging here.
