Hallo,
Sorry for not speaking German, I'm from Romania...
I bought a vw lupo 1.2 tdi 3l from Germany and i have some problems with the car. Going on google i didn't find much help, but i found audi a2 1.2tdi 3l and vw lupo 1.2 tdi 3l have the same engine and gearbox (DS085). This is why i'm posting here, hoping to solve my problem, which no one can solve it in Romania.
The main problem is an electrical one... Running a VAG COM test it tells me the G38 sensor is not working (no signal) so i went to atuo-service and replaced the G38 sensor. I have deleted the error but it keep showing up...
The gear box changes gears, go to reverse, neutral and stop.
The ECO mode is not working... from time to time it works, but very rarely.
Sometimes when i put the gearbox in Drive mode, driving the car forward, it forgets to change the gear up, i have no acceleration, the current number of the gear is flashing on the dashboard screen, then it get back to normal and continues the drive. Sometimes during this error, the warning speaker in dash board beeps several times.
Another symptom is like this: I put the gearbox in Drive mode, and when i drive the car, all the gearbox indicators are highlighted RND12345, no flashing or beep this time, the car still drives meantime, then it get back to normal and displays the correct gear and still drives away.
This is a major problem for me because I'm a student and I have to travel like 400km to go to the next town at school. I can't afford to get stuck on highway knowing my car has some gearbox problems.
Another thing is when the engine is cold, like the car was not started for 12 hours, outside temperature 20 degrees Celsius, the gearbox changes gears somewhere around 3500 rpm. After 30 minutes of driving it starts to changes gears faster then 3500rpm somewhere around 1800-2000rpm.
I have this car since November 2008. It's manufactured in 2001 and in 2004 the gearbox, clutch kit and turbo were replaced.
Since November 2008 i only made 1500km trying to figure how to fix this problem. I never went outside of the town because of this problem.
Thanks in advance!
