Default In&Out of LIMP Mode on 2003 Jetta TDI

I just got my 2003 Jetta TDI 1.9L Automatic and for some reason I got a check engine light while going up hill. it seems like it had issues shifting and it lost power as if it was stuck on first and it couldn't go faster than 25 MPH. with high RPM. It seems to be running ok now but it wont shift into Fift (overdrive) on the freeway with Check Engine Light. it only shifts into fourth at around 55 mph. where it used to go into over drive by then. The following day the chk engine light turned off and it was shifting normal again, but now It's acting up again. I need a recommendation on a OBD scanner that can read VW codes. PLEASE HELP.

Sounds like limp mode to me, possibly a bad sensor or connection. VCDS is really your only choice to be sure. Other OBD scanners often don't communicate properly with the TCM or the generic OBD codes don't accurately depict the fault.

FYI, this is only a 4 speed transmission. The "fifth gear" you are feeling is just the torque converter locking up. Good luck with it, these transmissions aren't the best. I swapped mine out for a 5 speed, best thing I've ever done to the car.

THANK YOU FOR THE ADVISE.
I purchased scanner and I'm trying to plug it to the Jetta but I can't find the plug. Supposedly the scanner that I bouth has all the codes specifically for the VolksWagen. We'll see. Do you know where the plug is in a Jetta TDI 2003 by any chance?

Has anyone tried obdcom and compared it to Vag Com for the more simple requirements.
Thanks
IMHO, put the $87.95 towards a VCDS, if you have a VAG car.
I can associate this with the "one size does not fit all" cliche...in my experience, the term "universal" isn't always, when it comes to VAG cars...but if you just need something to read a code, or clear maintenance/MIL lights, then why not...

VCDS is for the big boys!

Default VAGCOM vs. dealer scan tool

Hi all. Wasn't sure where to post this....

Are there any differences in the scan / data between our Ross-Tech VACGOM tool and what the dealer has? I've been tracking data (oil ash accumulation) using VAGCOM. I'm just curious if the data is the same when the dealer scans the car and we scan the car. I'm assuming it is, but you know what happens when you assume...

The control modules generate the data, the scan tool, be it VCDS or the factory scan tool, is just relaying that data. So both will show you the same thing... just one is affordable and doesn't screw over your paycheck because misGuided Fault Finding wasted 2.6 hours of your life, but then only flagged 64 time units. Damn you misGFF! Damn you to HELL!

LOL.... How could I forget the agony of waiting at the dealership, add the exorbitant shop diagnostic fee, and then the unreliable results and workmanship.
What was I thinking???

Hi all. I recently bought '99 Skoda Octavia 1.9 TDI, and since the first day I'm having problem when starting it in the moring. It takes too long for it to start. I have replaced coolant temperature sensor and changed glow plugs but still same. I recently read a post saying that its usualy pump timing. Thats why I timed my pump using vag-com app, and following this tutorial:
http://www.ross-tech...e/TDIGraph.html

After I did this still nothing. Maybe I did somethig wrong since I couldnt find skoda in the graph list, and I was selecting Golf AGR/AHF/ALH>4.99 since my engine is AGR.
At the first photo is the setting before I played with it
and the second one is the one after setting it.
Hope someone can help me find the solution.
Thanks in advance!

choose Select, Engine, Measuring blocks, look in the upper left corner of the screen for the file named xxxx.lbl.

Double click on that file and it opens up with NOTEPAD. Then you can print it or note the path, and do whatever you wish with it.
Hmmm, I can't find this using Hex-Net & VCDS-Mobile. Any suggestions?

Plugs should get volts with ignition on, if not, check Relay 109, wires, ignition switch.
If your Relay 109 is black, just order a new one.
