VW & Audi DSG Gearbox ECU

Volkswagen Audi DSG transmission fault

VW and Audi DSG Gearbox ECU problem

(Mechatronic Control Module Fault)


This is a very common problem for all Volkswagen and Audi vehicles fitted with the DSG (Mechatronic) 6-speed gearbox system.

The problem will normally be intermittent with the P R N D S light flashing and the gearbox going into the neutral (N) position, being unable to select forward or reverse gears. If left to cool down then the DSG gearbox will begin to work normally again. The fault will always become more permanent with time if left untreated.


The usual option when dealing with this issue is often opt to purchase an expensive new unit from manufacturer which will only come with a short 1-year warranty. Another glaring issue with this is that the defect has not been dealt with at production level meaning that new units are prone to fail in the same manner, usually after the short warranty period.


However our consumer friendly solution of rebuilding the original unit will engineer out the defect meaning that it will not fail again, plus we will provide an unlimited mile lifetime warranty.




Common Failure symptoms:

  • No forward or reverse gears
  • Dropping out of selected gear
  • PRNDS light flashing
  • No communication to the gearbox ECU


Common fault codes:

  • P0751 17135 – Shift Solenoid 1 (N88) Short To Ground
  • P0756 17140 – Shift Solenoid 2 (N89) Short To Ground
  • P0761 17145 - Shift Solenoid 3 (N90) Short To Ground
  • P0766 17150 - Shift Solenoid 4 (N91) Short To Ground
  • P0746 17130 – Pressure Control Solenoid 1 (N215) Short To Earth
  • P0776 17160 – Pressure Control Solenoid 2 (N216) Short To Earth
  • P0716 17100 - Transmission Input Speed Sensor (G182) Implausible Signal
  • P0722 17106 - Transmission Output Speed Sensor (G195): No Signal
  • P1707 18115 – Interference In Mechatronic Module

Hi, I have a Skoda Laura 2010 1.9 diesel with a DSG 6 speed gearbox from the VW group. The gears don't shift beyond 3rd gear. If I accelerate hard I get the the OBD11 code P2711 with PNDR blink. If I switch off and switch on the car it goes back to normal but gears don't shift beyond 3rd. Sometimes on Sports mode on high RPM the car shifts to 4th and 5th and works normally. Kindly advise. Do you have any repair outlets in India? Thanks! Kennedy

Hello, I have an Audi TT mk2 3.2 with a 6 speed DSG. I scanned the car and it displayed the errors 01315 and U0101. Are these codes a sign of a bad mecatronic ? The PRNDS is not flashing but the gear selected is not always recognized by the car. Thank you
ECU Admin says: 10/03/2020 10:10:18
Hi Tams, these are loss of communication fault codes, no communication to the gearbox ECU is a common fault. We offer test and rebuild for this issue, just select your part number from the following list: https://www.ecutesting.com/product-catalogue/audi/tt/ecu-transmission/

Hi, I have a VW Caddy Maxi 1.9 6 speed DSG which recently flashed the PRNDS and also jumped into neutral. It has given me error codes of - 18227/P1819 - Pressure Control Valve 2 (N216): Open/Short to Ground & 18248 P1840 Pressure Control Solenoid 6 (N371) Short to B+ Does this sound like a mechatronic unit has failed? If so what is your turnaround time from receiving the unit? Thanks, Naomi

Steve Gordon says: 03/10/2019 17:37:13
Hi, I've got a VW Transporter t5.1 with a 7 speed DSG box which has suddenly stopped changing gear and illuminated the engine management light and would only allow D1 to be selected whether in manual, auto or sport. I've had an auto electrician company we use have a look at the codes which showed in the gearbox module something like "Selector 4 intermittent fault" In your experience is this likely to be a mechatronic unit fault? Problem is I cannot sensibly drive the van anywhere
ECU Admin says: 04/10/2019 09:19:34
Hi Steve, the DSG7 mechatronic is very common for failure that will prevent selection of gears. Check your faults against our list here for more information: https://www.ecutesting.com/common-faults/volkswagen/volkswagen-golf-audi-a3-dsg-7-gearbox-problem/
