Hello.

I'm gonna puke off.
After I picked up my A8 4.2 last Saturday, I noticed on the highway that he was on the 3rd. ==References====External links== Aisle's on.
Even when driving normally, it only switches to the 4th, if you go off the gas (speed then drops again), you can go in the 4th. But don't accelerate or keep the speed, it just keeps turning up to the speed, which is the 3rd speed. Gear equals. If I switch to the Tiptronic cup, he'll show me the 4th. Come on.

Was reading the error today at Audi:

here only sporadic errors in memory:
- Encoder for coolant temp G62 unplausible signal
- valve control suction tube switching N156 (electrical). Electrical circuit faults)
- Key signal too small (transponder reading coil)
- Donor fuel supply indicator interruption/short circuit


He wanted to do a moment measurement on the gearbox, but he always flew out of the control unit as soon as the transmission was from the 1st. ==References== A gear shift, each time there was a blow in the gearbox and a jerk. He doesn't do that without a readout device.

In his experience, it can be several things:

- transmission control unit
- Air mass meters (engine then does not deliver enough power, but actually does not have the impression that power would be missing...)
- Gear damage

Now I'm as smart as before, great. Any of you have another idea. I'm in despair... if this goes on, I'll kill the box... I can't start to swap parts wildly now, but the parts are just too expensive.

Desperate greetings,

Matthias

Also Ölstand ist ok, hab ich schon nach Vorschrift bei laufendem Motor überprüft, ist auch laut Scheckheft erst bei Audi gewechselt worden incl. Sieb.
Fehlerspeicher ist leer (Motor und Getriebe keine Fehler). Der Audi-Mann hat evtl. auch das Steuergerät im Verdacht, da es die Kommunikation abbricht, wenn man per Diagnosesoftware eine Leistungsmessung machen will. Dann knallt auch der 2. Gang mit einem Ruck und Schlag rein. Bei normalem Fahrbetrieb macht er das nicht.

Gruß,

Matthias
