URGENT: Tiptronic problems RS6 C5
Sorry for the topic title, but this is really urgent.I have problems with my RS6 Avant from 2003.
In February, a new torque converter was placed, and the gearbox overhauled.
Now there are problems with the tranny since Friday, and next Sunday we start with 50 cars for a roadtrip to Italy (from the Netherlands) (eg for a charity to support).
The problems started with a rather abrupt way to switch back to 1.
Then it got worse, when i drove towards a red traffic light, let the car roll, and will accelerate again because it becomes green, the car revved, and he only "engaged gear" when the throttle is released. It also comes with a hard smack through the car when it engages gear.
Barely used the car and got it at the company where it was in February. And now he is completely cooked. On most crazy moments (driving away, acceleration orjust after switching gear) it doesn't engage gear. The motor revvs, but the car is not accelerating. Vagcom says at that moment that the torque converter is in "open" status. The blow (when the tranny comes into gear) is equivalent to switching the torque converter to "regulating" in VAGCOM.
What also is new since yesterday, when driving in Manual mode (I only drove the car in Manual since the problem started because the gear selecting is only when i want it to), the car suddenly went off selecting all gears, while we drove it at ~ 15km / h, the car would not go faster (no drive). He switched step by step from1 to 5, only on the display. Soon thereafter he went into Limp Mode.
The car is reset, and then with ~ 15kmu drove back to the garage (by the technician, this was during his test drive).
Who can help me? I need al info i can get to get the car on the starting grid by Sunday. The car shows no faults (no check engine light, vagcom has 0 errors), gearbox overhauled ~ 20,000 km ago. Torque converter was also newly installed.
