DSG Getriebeproblem 2. in 1. Gang
Hallo zusammen, meine Kuh 3.0 TDI, Bj.2009, hat seit einiger Zeit ein Problem. 🙁
Nach längerer Autobahnfahrt, wenn ich an der Ampel abbremse gibt es einen heftigen Schaltschlag vom 2. in den 1. Gang. Dieses Problem ist nur akut, wenn ich lange Strecken gefahren bin.
Gestern war ich beim Freundlichen und es wurde eine Diagnose durchgeführt. Bei den Punkt Getriebe sind folgende zwei Fehler vorhanden:
Fehler 8130 Steuergerät interne Prozessorüberwachnung
Fehler 8351 Steuergerät interne Prozessorüberwachnung
Audi meint vermutlich Mechatronik, Kosten mit Einbau 2500,-
Es gibt wohl eine TPI für den Mechatronik Rep. Satz dieses hätte aber einen anderen Fehlercode und ist somit nicht möglich!
Meine Frage nun ist es sicher die Mechatronik oder könnte es auch andere Ursachen haben. Bin gerne bereit die 2500,- auszugeben, aber dann muss der Fehler auch behoben sein. Ich lese hier auch oft Fahrstufensensor?
Vielen Dank für eure Hilfe.

Mechatronik ?
Mir kommt vor, dass Euer Problem mit einem Update oder mit einer neuen Mechatronic gelöst werden kann.
Bei meinem Q5 177 PS, s-Tronic aus 5/2014 gab es das Problem nie, weil das Getriebe niemals vom 2. in den 1. Gang schaltete, sondern immer bis zum Stillstand im 2. Gang blieb. Der erste Gang wurde erst beim Stillstand des Fahrzeigs eingelegt.
Problem usually goes away with latest firmware, (on my Q5 it did and latest firmware on flashdaten was 11) previous firmware was 10. Remember the transmission service interval is 65k km, flushing pipelines with pressured air too helps especially if you have the metallic external filter which is not serviceable, remember to change the internal filter, clean pan and magnets. If you have the plastic one you need to change both internal and external filter.
Wer einen Schaden am Getriebe mit einem Softwareupdate beheben möchte, hat etwas Grundsätzliches nicht verstanden. Wenn es vorher funktioniert hat und jetzt nicht mehr, ist ein Bauteil defekt oder das Öl zu stark verunreinigt oder gealtert. Ein Softwareupdate kann zu einem veränderten Verhalten führen, repariert jedoch keine Fehlfunktionen.

For my Q5 this applied:
There is a firmware update which also corrected my 2 to 1 gear shift jerk issue. Read the TPI below for more information, also confirming what I have said before.I usually can support my answers with specific documents so happy to answer to any different opinion.
TPI 2027286/9 (10/10/2016)
SVM code 02A054
Also managed to remove from my tfsi 2.0 s-tronic pedal time lag/hesitation (about 0.5-1sec) when accelerating from still. The remedy was DTE PedalBox. The issue was neither transmission nor turbo charger lag.
As for hardware issues my Q5 was serviced by Dealer upto 100,000km and transmission fluid was degenerated decomposed. Shift quality was suffering. So bad oil quality and not maintained trans. filters can lead to hardware problems in the long term.
Then Audi has an s-tronic transmission kit solving the printed circuit lamination deterioration issue which restores proper operation of s-Tronic.
Yes, firmware updates change the behavior of the system, so this can improve the clutch control and this feels like fixing it. The DTE pedal box modifies the characteristic of the gas pedal signal and this feels like tuning, but is in fact an override of the protective function of the acceleration control that leads to higher load to engine and gear box causing the indicated oil damage. You even can reach this by stepping more on the gas, but this feels different. The resulting damage of the electronic components can be fixed by replacing some parts. An interesting problem appears if the transmission step sensor fails because this cannot be fixed as easily as the gearbox control modul which can be dismounted just by opening the oils sump.
Nevertheless zero lag enhances driving enjoyment and removes hesitation and minimises safety concerns due to slow response. My driving style is with pedalbox and chiptune (sport mode).

Are you saying that DTE PedalBox can cause damage, due to to higher load to engine, to HW parts (maybe timing chain or tensioner) and transmission electronic component (those 2 you described)?
or
Are those transmission electronic component failures something usual with DSG transmission limp mode failures and are not related to pedal box???
If you use pedal box you do this usually to have the illusion of a faster car, so I think you tend to accelerate a bit faster and this causes in more load to engine and gear box. Which part fails first and why depends on many different factors (maintenance, cold starts, short distance driving, drivers behavior) and pedal box supports you to treat your car a bit harder.
As I heard up to now DSG transmissions are a bit tender to oil consistency and in fact small technical failures end often in expensive repairs.
What is the primary advantage of PedalBox is not the higher acceleration (which that is an illusion) but the lag removal or immediate response to accelerator pedal movement. So basically one gains the 0.5-1 sec delay/lag when accelerating from still. This is not an illusion but real. No other car can now accelerate faster than me from still is the feedback I am getting because I now have no hesitation or lag or delay in response from the engine.
I don’t think that this damages anything or gives higher load to any engine or transmission parts. It just saves on delay for immediate engine/throttle/movement response.
So my conclusion is that it removes the delay/lag parameter Audi has designed to the accelerator pedal/throttle for unknown reasons to me.
DSG S-Tronic is one of the best automatic transmissions I have had but negative need more frequent service 65000km because transmission fluid gets deteriorated or decomposed also recommended to flush fluid from the main transmission pipelines, change filters, and maybe consider doing the fluid change twice e.g after 5000km in order to flush oil again that remained in the converter (clean magnets and pan again).
