Replying to: shrifty (Oct 10, 2008 1:02 pm) >>>>> Scanned system for faults. Found code for Cylinder #4 Glow Plug circuit Q13 electrical fault (P0674). Called the Tech Line. Advised to perform guided fault finding and transmitted it to tech Line. Checked all connections, fuses etc. All OK. Advised to clear code and retest in AM. Retested next morning. Fault came back. Called Tech Line. Advised to swap 3 & 4 glow plugs and clear code and retest. Cycled key approx 10 times. No light at this time. Let car sit to cool off. Retested again. At this time the light is off. No codes have returned. Tech Line advised to release the car at this time. They advised to bring the car back if the light returns. >>>>> My take: No real diagnosis here. Having enjoyed outstanding reliability from my previous Toyota, Honda, and Acura cars and suffered the pain of unreliability from a Chrysler Town & Country minivan, I have my fingers crossed and am hoping I did not make a wrong buy. The car is truly a blast to drive so perhaps that needs to be seen as the offsetting factor against any reliability issues.

Replying to: r108j (Oct 15, 2008 9:22 pm) On my prior TDI, I would get an erratic MIL every once in awhile. It was almost always a glow-plug code, yet even with the light set, the car would start perfectly fine in the dead of winter. I'd reset with my VAG and go about my business. Sometimes, just cleaning the contacts of the glow-plugs would reset the light on it's own. Therefore, I'm of the opinion that the glow-plug sensor's are just ridiculously sensitive. This happened maybe twice a year. The good news is that it's just a glow-plug so in the scheme of things not much to worry about.

Replying to: sebring95 (Oct 16, 2008 4:19 am)  GEEZ makes one crave more global warming! I had a so called slow up to temp issue and the VAG.com codes indicated either glo plugs/thermostat. It turned out a change in thermostat did the trick.

| Edmunds purchased a long term tester of the new Jetta TDI. Where is the blog of what they're doing with it? | |

Replying to: shrifty (Oct 16, 2008 5:36 pm) Think about the build process. It's almost impossible to make something that complex with so many moving parts absolutely perfect.

I currently have a Corolla and am considering a TDI as its replacement, but I have some questions about them. What was the first year of the high MPG TDI? How reliable are they (keep in mind the Corolla is as reliable as a Swiss watch)? How hard are they to start in cold weather, and how long does the engine have to run before they start producing heat from the heater? How many miles can a TDI be expected to last with a reasonable amount of care? I expect my Corolla to go at least 200K miles, and probably more like 300K. Is it reasonable to expect a TDI to go longer than that because they are a diesel? I've noticed in the price range I've been looking at ($5000-$8000) most of the cars are very high mileage (almost all of them have in excess of 120K miles on them). I was hoping to get something with a bit less miles, What keeps their price so high? Never owning a diesel, or a VW before, is there anything else I need to consider?

Replying to: bottgers (Oct 17, 2008 5:56 am) Now if you said reliable as a battery operated quartz watch either Swiss or Japanese, I would jump in and say go for it. HOWEVER.... A swiss watch really needs a lot of maintenance. (your statement could imply you never had a swiss watch/s or you have had "a" to nothing but swiss watches and are USED to that level of maintenance and repair) How cold is the weather you will encounter? I have started the car in 20 degree weather and  altitude (INXS of 6,400 feet) INSTANTLY and with no additives other than the location specific ULSD fuel. If the weather is colder than that, I would say you may want to look at additives such as Power Service (anti gel in this case) Do not buy a diesel for the "fantastic" heaters. You will be highly disappointed. Diesels do not generate NEAR the heat that a gasser does. If you are remotely interested, longer term this is a GOOD thing - shorter term wear a parka.. The newer TDI's have OCI's as high as 30,000 miles vs a normal Corolla 3,000/5,000 miles. At the worst 10,000 miles. At 100,000 miles my TDI needed a TB/WP (aka parts R/R and computer tune up). In comparison the Civic needs a TB/WP change (aka parts R/R and computer tune up). 105,000 miles. I think by the prices you are encountering, the question of longevity is being answered. I think there is a 60/40 chance you will be disappointed, so I would stay with a Corolla/Civic. I say this even as I have a TDI 110,000 miles/Civic 71,000 miles side by side. While both have been highly reliable, the Civic's consumeable items wear much faster. One thing that does NOT show up in the cost equation: do you want a commute car that can handle highway (Civic) or do you want a highway car than can handle commutes (TDI). Obviously if your commute is on highways.... I have been more than satisfied with both. Under the same daily commute, TDI does 48-52 vs Civic 38-42 mpg. SAME driver. |
