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!

Replying to: redvw (Nov 03, 2008 7:05 am) 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. |

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... |

Finally received my Jetta TDI sportswagon after waiting about three months( ordered 07-11-08). Has DSG transmission. Only have driven it about three hundred miles. Tested MPG on a couple of 30-40 mile interstate trips. If driven at about 60 miles an hour( 1800 rpm) , I got as high as 47.4 MPG. Not bad. expect better after break in. Even at 70 expect 40+ mpg Handles great.built quality appears excellent. Nice amenities including two 12 volt outlets and a 120 volt outlet. My only complaint is the sunroof shade/screen, the interior can be pretty bright if the sun is at a certain angle. |
