#5452 of 6655 Glow plug repalcement & wiring harness
Nov 27, 2007 (12:27 pm)
I have a 2003 VW Jetta Wagon TDI. Recently the check engine light came on and I went to dealer to have diagnostics done. I have one faulty glowplug and they want to replace all glowplugs and the wiring harness. Big bucks! Get second opinion or try something another VW TDI owner has tried and was successful. On a small income and don't want to put out this if I can put it off. But don't want to ruin engine either. Thanks for any info or suggestions.

Just a heads up. A very reputable import mechanic said everything looked okay except the positive battery cable was loose. They replaced it and said that the car has not reproduced the symptoms since. (they are fixing something else on the car (unrelated). But when I get the car back I'll let you know if the problem was resolved by replacing/tightening the positive battery connection.

Glowplugs on your 2003 are due to start needing some attention. (I also have 2003 TDI... the BEST A4 TDI ever made before they switched to new engine design) I had one GP go bad last winter.
There is no need to just replace everything. You may want to educate yourself about the glowplugs 1st. Start by reading this. (dont forget to read ALL the pages)
After you have read thru that, I would be glad to answer any specific questions you have about the TDI glowplugs.
Any parts you would need (glowplugs, harness, relay) are available here.
Even if you replace ALL 4 GPs and the harness, it would cost less than $200 (but you should not need to do all that)

Nov 29, 2007 (12:20 pm)
Need some help - any comebacks appreciated. Have a 4cyl, Gasoline 2.0. with problems. Hit a raccoon on the right front side and the check engine light came on afterwards. (raccoon cited for DUI and has since disapppeared). Insurance not covering this and it is getting very expensive. Trying to tie the problem with the accident - hard to prove it was accident related. Car ran perfectly prior to the accident.
Engine starts ok, however, it will not pull itself. Engine will not rev up at all - when I step on the accel. the engine cuts out. Runs rough until the engine warms up - some smoke until it gets hot. Even then, little or no power, and the engine sputters upon putting into gear. It will only get up to around 40mph. Have had two separate diagnostics on it, one indicated the engine was misfiring. Changed the plugs, wires, air filter, fuel filter. Had the second diagnostic performed by a VW dealer and it indicated the ignition coil was the problem. Have changed this out and the problem remains. I run premium fuel, maintainence is regular - any thoughts on the cat. converter? Other possible problems? Solutions? Many thanks to anyone who responds.

With the key out of the ignition find and press the odometer reset button (hold down)
Turn the ignition on (warning lights come on) wait about 10-15 sec until most or the lights are off (still pressing odometer reset button)
Turn ignition off (button still pressed) and remove the key
Release reset button
Interval should now be reset. If this is not the case, repeat the above procedure
#5460 of 6655 1999 Jetta, Horrible Gas Mileage
Nov 29, 2007 (8:42 pm)
hey guys, hoping some of you can help me out.
i've been getting really bad gas mileage on my 1999 Jetta, automatic, when i say bad i mean really bad! i can never seem to break 350-375 km before the gas light comes on, i am not a very aggressive driver, i maybe do 10kmh over the speed limit and i dont do any jack rabbit starts,i do mostly city driving with the odd hwy drive
i have tried numerous things to try and improve this but none of them seem to work i have a K&N drop in air filter (which is only 5 months old), i changed my fuel filter, i recently had my Catalyst replaced (under VW warranty), my tires are at the recommended pressure, i've used numerous STP oil, gas and fuel injector treatments, i have literally nothing in my trunk or anything "extra" in the car, and i do my oil changes every 5k or 3 months,i was running Castrol High mileage 10w-30 but was told to run the reccommended 5w-30, i did that but no change in mileage, i was going to check and clean my MAF sensor but i've been to every auto parts and hardware store in my area and none of them carry the 5 point Security T20 torx driver that i need to remove it, i have tried to find one off ebay or something but no luck so far, i also checked for brake drag and there seems to none. i have owned the car for about a year now and haven't really noticed the mileage till early this spring ( i thought the cold weather had something to do with it but apparently not) and i have been trying to figure it out ever since, i purchased the car used
i just recently changed the plugs and wires, both OEM, i'm just waiting to see if that does anything but if it doesnt i think i have to take it to the dealership and have them check it out. if thats the case, what should i ask them to check out, or what should i be prepared to replace on the car? what else could possibly be affected my mileage so much?
i know some people might say that 350 aint bad in the city but i think thats garbage for 2.0L 4 kicker engine, i know people that drive jeeps in the city that get the same if not Better MPG then me!
any ideas are greatly appreciated

EPA adjusted rating is 19 or 20 mpg city for a 1999 jetta or "new jetta" respectively, not sure how that compares to "350-375 km before the gas light comes on".
CR does a much more severe city test. Back in 1994 they got 16 mpg city with a Jetta III.
