Salutare, am și eu o problema cu un passat 2010 cod motor caxa și cutie dsg 7.
Pornesc mașină, ea rulează perfect până în treapta 3, când încearcă să schimbe in a 4a nu o ia și îmi schimba automat iar în a 3a și se tureaza, începe să licare in bord treptele și dacă mă opresc sa o bag in marsalier nu se mișcă mașină. Opresc motorul, îl repornesc și merge iar și in marsalier și în treptele până intra 4a.
Pe tester îmi dă codul de eroare p072f stuck in gear 4 (intermitent).
Ce poate să fie?

De regula este o problema mecanica de uzura unde responsabilul cu cuplarea unei trepte nu poate sa o faca datorita defectului. Poate chial solenoid ars!
99, 9 % trebuie cutia jos si desfacuta!
Costul pentru cine o face singur este mic financiar vorbind dar pentru cineva care o duce la atelier... 1000 e +-
Multi posesori o merita cumva deoarece cand le spun ca trebuie schimbat uleiul la dsg 7 spun ca nu trebuie facuta treaba asta, chiar mecanici care sustin asta desi fabricantul cand vorbeste despre life time oil nu se refera la masini cu anumit km mult peste acel life time!

The OBD-II trouble code P072F indicates that the transmission is stuck in 4th gear. This means the transmission is not shifting properly and may be experiencing internal issues, a faulty Transmission Control Module (TCM), or problems with the transmission valve body solenoids.
Here's-a breakdown of potential causes and solutions:
Possible Causes:
Internal Transmission Failure:
This could involve worn-out components within the transmission, such as bands or clutches, preventing proper shifting.
Transmission Control Module (TCM) Failure:
The TCM is responsible for controlling gear selection. If it malfunctions, it can cause the transmission to get stuck.
Transmission Valve Body Solenoid Failure:
These solenoids control fluid pressure within the transmission, and if one fails, it can cause a gear to be locked.
Wiring Issues:
Corrosion or damage to the wiring harness connected to the TCM or solenoids can disrupt communication and cause shifting problems.
Low Transmission Fluid:
Insufficient fluid levels can cause various shifting issues, including being stuck in a gear.
Gear Position Sensor:
A faulty sensor may be providing incorrect information to the TCM, leading to the stuck gear.
Troubleshooting Steps:
1. Check Transmission Fluid:
Inspect the transmission fluid level and condition. If it's low, look for leaks.
2. Inspect for Leaks:
Examine the transmission for any fluid leaks around the pan, lines, or seals.
3. Check the TCM:
Look for any signs of corrosion or damage, especially if it's located in an exposed area.
4. Scan for Other Codes:
Use an OBD2 scanner to check for other related trouble codes that might provide more specific information.
5. Consider Professional Diagnosis:
Given the complexity of the transmission system, it's often best to have a qualified mechanic diagnose and repair the issue.
Possible Solutions:
Transmission Relearn/Reprogramming: In some cases, a transmission control module relearn or reprogramming with the latest software can resolve the issue.
Fluid Replacement: If the fluid is low or contaminated, replacing it with the correct type and level may help.
Solenoid Replacement: Defective solenoids may need to be replaced.
Wiring Repair/Replacement: If wiring issues are identified, repair or replace damaged wiring.
Internal Transmission Repair/Replacement: If there is internal damage to the transmission, it may require a rebuild or replacement.
