Replying to: redvw (Nov 02, 2008 4:28 pm) TDI does not need to be plugged in... but if you want heat inside the cabin within 10 miles, it sure helps.   An automatic xmission tends to generate more heat into the cooling system than a manual. (That is one reason automatic gets lower MPG). VW knew this and added electric heater for antifreeze when you have manual xmission.   For CERTAIN you should cover the radiator air inlet during the winter. Lengths of pre-slitted 1/2inch pipe insulation is PERFECT for this job.... just slips between the slats of the grille. When ambient temps go up, it can be easilly removed and tossed in trunk with spare tire.
#2541 of 3704 Jetta TDI Reliability by redvw Nov 03, 2008 (7:05 am)
I have owned 4 VW's, the last one was a Corrado. The Corrado and Rabbit GTI had reliability problems (electrical related). Four different VW dealers were not able to diagnose or repair the Corrado causing me to sell it with low mileage.   I am considering the purchase of a Jetta TDI next year, has VW reliability improved?

Replying to: redvw (Nov 03, 2008 7:05 am) I would say yes and no. While I do not have any experience with the two that you have mentioned, (ok I had a 70 VW Beetle app 250,000 miles all but 10,000 put on by me, 78 Rabbit 95,000 miles, 03 Jetta TDI 110,000 miles) the latest 2009 incarnation Jetta TDI is a WAY better vehicle than the previous generations. What has not become real clear (by virtue of being BRAND new) are the 2009's quirks. (and ALL vehicles have them) Also, not many have the requisite 90,000 to 150,000 miles to talk about a significant cycle up to and past the first timing belt/wp change(120,000 miles I am told for the 09 model). At those levels, one can swag to the next TP/WP change.   Another is the so called definition of reliability. What does that REALLY mean?   As a comparison, I have the "highly reliable" Honda Civic (04) . Honda defines it SANS "consumables" Well, needing tires at 74,300 miles and three alignments the way the Civic does, does NOT count in the reliability measure, even as I am still running oem tires on the VW Jetta 110,000 miles and have not NEEDED any alignmenst. So at 300 per tire set and 90 per alignment, the Civic has cost me $ 570. MORE in operating costs. While this is factored in at the per mile driven cost. It clearly is NOT factored in the reliability measurement.   (As history I also had a 82 Honda Accord manual) Replies to this message: ruking1 (Nov 03, 2008 8:48 am)

Replying to: redvw (Nov 03, 2008 7:05 am) We had one problem, an electric motor that controlled an air flap, on our 04 Passat TDI purchased in 07/04 that now has 50,000K miles on it. Not one single problem with our 06 Jetta TDI purchased in 05/06 that now has 30,000K miles on it.   By the way, based on our frustrating experience with an Audi and a nephew's similar experience with a Corrado, I suspicion your problem on the Corrado was the fuse panel.

Replying to: ruking1 (Nov 03, 2008 7:26 am) While in theory the VAG.com, OBD port, aka onboard computer should be an almost direct pointer to monitored items AND cut down the common corrective action of "throwing parts the problem" : it does seem a lot of VW dealers continue to "throw parts the problem" !?
#2545 of 3704 Codes P1550 and P0101 by freeantelope Nov 03, 2008 (9:52 am)
I am having power loss on my 1999.5 Jetta TDI.   The whole story is important here probably. Head needed rebuilding, has new camshaft, timing belt, tensioners waterpump since it was all open. I also had the turbo actuator valve replaced (the bladder gizmo behind the engine). Right after that the turbo worked great, car ran like a dream for about a weak. I then noticed when the turbo would spool when at high RPMs that it would skip and then plop into limp mode. It has gotten progressively worse so that now it will drop off almost from the first acceleration in first gear. It will usually fix when the key is cycled.   when I run the codes I get P0101 an P1550 (regular handheld jobby), and under the the Vag-Com there are also codes for the rear ABS sensors.   So far to fix this issue I have replaced the Turbo Solenoid (up by the windshield with the hoses going to it), I have replaced the MAF....I have taken apart the hoses going to the air filter (all clear). I have visually inspected the vacuum hoses and though a little frayed don't see any breaks. The air filter is relatively new.   The connector plug (that plugs into the MAF) is a replacement plug so it leads me to believe someone looked at replacing that before I came onto the scene. I am thinking I should check to make sure that is wired well...but what else should I try. Any advice, happen to anyone else? I am reaching the end of my wits thinking about it....need some things to check so I feel like I am sniffing out the problem....give me your best shot!   Jason WVO 2001 jetta TDI GLS auto 1999.5 Jetta TDI GL

Replying to: redvw (Nov 03, 2008 7:05 am) While my '00 TDI had a few niggling issues here and there, I'd say it was very reliable. My clutch was fine at 180k (car was totaled) and I had considerable performance mods that made it possible to slip pretty hard if I dumped the clutch.   Neighbor stopped by this weekend and he'd recently turned 150k on his '06 Jetta TDI. The only "repair" he's made was to replace the glowplugs a few months back. I ask him about the clutch after reading some of the posts here and he said said it was fine. Granted we (as do most TDI owners) drive largely on the highway so there's really no reason the clutch won't last a very long time. I'ver also not ever heard of anyone that lost a manual tranny on a tdi.
#2547 of 3704 150k on a 2006! by elias Nov 04, 2008 (3:29 am)
150k on a 2006 TDI is awesome. How often does this dude replace fuel filter etc ? Does he use the factory maintenance sched and do ya know, is he a member of Fred's? cheers...

#2548 of 3704 Re: 150k on a 2006! [elias] by sebring95 Nov 04, 2008 (5:13 am)
Replying to: elias (Nov 04, 2008 3:29 am) He's doing 20k on the fuel filters. Everything pretty much by the book and he does it all himself. He's not on web, although I printed some tips and such for him from Freds. I also helped set him up with Bentley manual, a VAG-com and an old laptop. He doesn't get too excited about the miles....his '99 Ram diesel has over 350k as that used to be his commuter. He's a part-time farmer and just always commuted in his truck until he bought the TDI.
