Salut,

Ce serait bien que tu controles ce defaut :

* VW DTC 17026 (P0642) - Sensor Reference Voltage A: Circuit: Low
Bascially, the ECU is complaining about a power supply issue.
You'll want to check first the leads to the ECU.
It's common too, that power loses spawn at the following:
Check Wiring from/to the following Components and Components themselves:
* Manifold Pressure / Boost Sensor (G31)
* Intake Manifold Tuning Valve Position Sensor (G336)
* Low Pressure Fuel Sensor (G410)
Also remember, there is a TSB for the software update and component replacement from VWoA:
* Check Engine Control Module Software Version, if necessary perform Update.
* Replace Intake Manifold Runner (V157) with updated part.
