Q: What kind of mileage on vw jetta diesel this winter?
2006 new vw diesel tdi........this summer the mileage was the high 40's
A: You must be down under.
Should be about the same, maybe a touch less if you let it warm up.
Q: Noise when 2003 VW jetta diesel is running?
Whether or not the car has the engine running, I hear a constant ticking sound coming from all the speakers. And only when the radio is on. I had suggestions on checking the spark plugs but this is a diesel. I also got a suggestion on chcking for a bad ground and I will be doing that. But I was wondering if anybody else has encountered something like this before or has any more suggestions that would help in troubleshooting.
A: my answer is try to check it out first on auto repair shop...
Q: Does anyone know about the VW Beetle or Jetta TDI, diesel?
I am considering buying a VW diesel (beetle or jetta) and I would like to know the pros and cons.
I own a VW beetle now (2.0) that is starting to have serious problems and I want a car with the best gas mileage. These diesels get up to 50 MPG. But I do not want to sacrifice maintenance/repairs for gas mileage.
I want a reliable car.
Thanks for any help.
A: We have 1 gas Jetta & 1 diesel Jetta, both manual (stick) shift. My Dad has a diesel Jetta (automatic) - we love our diesels. Here in Canada they get a bit sluggish to start in the dead of winter (-25c) but otherwise are a great car with great mileage. I use synthetic oil in mine so can go 10000-12000km before having an oil change. The fuel filters are pricier than a gas engine, overall maintenance cost is about the same. Generally, diesel engines outlast their gasoline counterparts as the engine itself runs cooler than a gas engine. You should check the availability of diesel at local stations & along the route you take to work - just a practical suggestion, because it's no fun having a car with great mileage if you have to drive way out of your way to find fuel for it. Diesels will also run on alternative fuel; check out http://www.greasecar.com ......... cheers.
Q: Where could I find a schematic of the 1990 VW Jetta diesel engine?
Don't need a picture unless it is labelled.
Need a pic and/or schematic labelling parts and where fluids go.
Thanks.
A: go to www.alldata.com or go to the local auto parts store and pick up a Chilton's or Haynes repair manual. Sometimes the library will have these as well
Q: how to time the vw jetta diesel timing belt where is the mark?
A: all depends on the year and motor you have.. but the most common VW timing is:
Crankshaft pulley, notch up at 12 O'clock
Camshaft gear, dot on back side lines up with top of, inner half of, timing belt cover on front of engine.
If you have a newer one, just drop me an E-mail with year and engine type and I will see if we have it in our system.
Happy Holidays
Q: New VW Jetta Diesel engine question?
I want to buy a New generation Jetta Diesel. But how are maintenance costs like?
What are the oil change intervals? Synthetic oil?
How often do I need to change the fuel filter?
What are some other maintenance items I need to change often?
A: First, it comes with 3 years/36k miles free maintenance.
The other post is wrong, he gives intervals for a gas engine, - the diesel engine has different maintenance intervals.
Oil change is 507.00 VW spec oil, which is a synthetic. 10,000 miles between changes.
Fuel filter is every 20,000 miles since it's a diesel, costs about $50.
Timing belts costs about $1200 and is done every 120,000 miles.
If you get the DSG transmission, transmission fluid changes are every 40,000 miles and costs about $400. The manual transmission gear oil should be changed every 80,000 miles.
Q: What should the idle RPM for a 1994 VW Jetta DIESEL be?
A: if it's diesel for sure is like 450-550 rpm
Q: Transmission fluid is a diesel VW Jetta?
I dont know if the transmission fluid has ever been changed on my 2001 vw jetta about 150 000 k. I am experienceing a bit of tranny slippage and wondering when tranny fluid should be changed and where the holser is located under the hood? (could not find anything about tranny fluid in my owners manual)
A: The transmission fluid in the VW is "lifetime fluid," having said that, normally for most people in the dealership that I was last at we would suggest replacement of the fluid, clean screen/replace filter (if equipped) and a new pan gasket every 100,000 miles or 10 years, which ever was first.
This would translate to about 162,000 KM or so, but given your situation, I'd suggest the service now. Please understand that there is NO DIPSTICK to check the fluid level; the plug from the transmission needs to be removed (new plug put on after the service is done) to add the fluid.
The fluid cannot just be added to the transmission: the dealership (normally they are the only ones with the VAG tool that can run the procedure to refill the transmission) does this by temp and software control from the VW scan tool. Failure to follow the proceedure will blow out the seals internally in the transmission, thus requiring a overhaul or replacement.
The cost will not be inexpensive: the fluid is a special fluid only available at the dealership and it costs about $20.00 or so a US quart, with at least 4 quarts being needed (some models more), plus labour charges (most places charge 1 hour of the posted labour rate) and sales tax as required.
I would normally think that if the transmission were truely slipping, the check engine light would come on, but I also know that doesn't always happen.
Now, in some locations, the VW powertrain warranty would cover internal transmission issues: in the US it would cover the original owner for 10 years or 100,000 miles and I think in Canada (don't hold me to this:) I think it was 160,000KM for the coverage, but again it applies only to the original purchaser of the vehicle.
A non dealer can perform a service on the transmission, but they need to have the correct VAG scan tool and software to do this, but most non dealerships probably cannot perform this for you.
I hope this helps, a car nut.
Q: 1985 VW Jetta diesel fuse box?
I have a MkII diesel jetta with the 1.6L engine, and I need to replace the fuel pump fuse I believe, since the fuel pump refuses to activate at all. However, the only diagrams I can find for the MkII fuse box layouts are for gasoline engines, which have the fuel pump fuse in a different slot I think. I am hoping that somebody can send me a link or picture of the layout for a diesel MkII fuse box, or simply tell me which slot it goes into, thanks a lot!
A: The VW 1.6 litre diesel engine does not have an electric fuel pump, hence the reason you cannot find the fuse. If it did have an electric fuel pump, then it would be controlled by a relay. Get the Robert Bentley manual for VW, its the factory manual- chock full of information and diagrams you will need.
Q: Does anyone have any opinions on whether or not it would be wise to purchase a VW Jetta diesel car?
A: I have driven a used VW diesel every day since 1981 ( 4 Dasher diesel wagons, 2 rabbit diesels, and 2 Jetta TDI's ) and they normally go up to 200,000 miles without many problems. My present 99 Jetta has given me a consistent 50-52 mpg, city /hwy combined, when the temp is reasonably warm, about 48 when it is cold ( live not far from Buffalo, NY ) starts up great down to -20 with out being "plugged" in. Occasional extra additives are helpful. My two 1981 Dashers that I still have get around 37-40 around town and 45-49 highway. Parts can be expensive especially if you don't shop around. If you don't do your own work mechanics can be scarce sometimes depending on where you live.
The main thing is diesels run good after getting warmed up. If your primary drive is short jaunts of less than 10 miles before stopping I wouldn't recommend it. You will probably have engine problems ( ruined one engine that way ). If you do a lot of driving the diesel is the way to go. No experience with anything of VW newer than 99 though. Not certain how the new fuel is going to affect the diesels. So far mine is running ok.
Q: 1990 VW Jetta Diesel glow plugs?
Could someone tell me how to change the glow plugs in a 1990 vw jetta? Or give me a link where it would give me instructions on how to? Thank you
A: To figure out which one(s) are bad, you can test the current moving along on the wire connecting the glow plugs together. between the plugs there should be around 5 amps difference between the plug. You can also, while the engine in cold, check the resistance from the top of the plug to the engine block. I can't remember quite what the resistance should be but it should be low....less than 10 ohms. Anything more or overload means its burnt out or not working great. You have to disconnect the glow wire before you test it.
The two on the right hand side of the engine aren't too bad to change, but the other require you to pull the injector pump. I've tried to do them with the pump on but it took me hours and I wound up cross threading it....yikes
To change them, loosen off the wire, them unscrew the glowplug. No special tools needed. When you're putting in the new one be very careful not to cross thread it. The aluminum head is real easy to mess up.
Its been my experience that glow plugs do get old and lose their zing. A mechanic I know charges around 120 canadian for a job when the injector pump removal is needed. One can do it themself, but unless you're a 3 banana skill level I'd take it to a diesel guy

Q: Rough shifting when warm 2001 VW Jetta Turbo Diesel?
For a couple months now my car has been shifting rough and sometimes will bump at the end of a shift. (Up shifting only). I took it to a couple mechanics and the one I trust said he thinks its the tranny and needs a over-haul. But my concern is, the car only ONLY shifts rough when the car is warm and at prime temp but not when its cold. Thats why I think it could be some sort of sensor?
Im getting it scanned soon... but looking for ideas or experiences with this.
2001 Turbo Diesel VW Jetta, about 160,000 KM
I talked to VW and they said its "Life-time tranny fluid".
Where are shifter assembly bolts located? and what did that run you $ wise?
A: Have the transmission fluid changed by a dealer, they have the special filler tool and its best to use VW fluid.
Q: where is the alignment mark for the 1989 vw jetta diesel located? the fuel injector,camshaft and crankshaft m
alignment mark for the fuel injector ,camshaft and crankshaft location
A: You are not going to be happy. I just looked this up in our shop references.
You need a special tool, a setting bar #2065A, that gets placed across the back of the last cam journal and timing is found by using feeling gauges and how far the setting bar is off the head.
Lets toss in there, the special pin and clip needed to lock the injector pump inplace.
Crankshaft is easy, just line up TDC for cyclinder #1 using the mark on the flywheel.
I have done many VW Engines, but this one would require me to get buy new special tools and have the printout laying right there with me..
Sorry.. I tried
Q: Are the operating costs of owning a diesel VW Jetta greater or less than that of the regular Jetta?
A: Less.
Diesels exist because they're cheaper to operate. Better mileage, and the engine is much simpler. With fewer parts to break or get out of adjustment, it will last longer. Also...the extremely high compression inside diesel engines requires a more robustly built engine. Because they're built stronger, they last longer. The cars holding the records for most miles are all Mercedes...diesel mercedes. 1,000,000+ miles. One million miles divided by the cost of the car - the cost per mile is miniscule.
Q: I have an 89 VW Jetta Diesel what kind of mpg should i be getting ?I am getting 33 now .?
A: It depends on a variety of factors; the type of driving that you're doing, the speed you travel, and very importantly at this stage of the vehicle's life, what condition the motor is in internally, the fuel injection system (pump pressure, injectors, pump timing etc) and even the clutch condition can affect the milage (if its slipping, it sure can affect the milage!). I cannot answer the question except in the most general terms; you haven't given enough information to determine if its low or not.
However, some generalizations can be made. If the driving is mostly city driving, then its about right. If you're driving steady freeway speeds about 60 or so, then its low. When I owned one of these vehicles way back when, I remember that it got about 50mpg at freeway speeds, but, I drove no faster than 65 mph; if you drive faster, expect less. If the engine is low on compression, which is certainly possible from normal wear and tear (if has more than 125,000 miles, expect that compression will drop off... most of these motors made about 200,000 miles or so; a few people got a lot more, some a lot less, depending on driving conditions and driving style). One thing, be sure and use the correct oil for the motor, this too can effect your milage as well.
Hope this helps, a car nut.
