A simple breakdown of how the transmission control unit fails
P173500 (Position sensor for clutch 1, electrical malfunction) or
P173600 (Position sensor for clutch 2, electrical malfunction).
Do not book the vehicle in for a routine "Service" when this warning light appears. Service departments may perform and charge for routine service items on an undriveable car before addressing the underlying fault.
Explicitly ask for a "Diagnostic Inspection" for transmission fault codes such as P173500 / P173600.
General obligations of vehicle manufacturers under statutory Australian law
Under Section 54 of the ACL, goods must be fit for purpose, safe, durable, and free from defects considering the nature and price of the product.
Statutory consumer guarantees exist independently of express manufacturer warranties. Premature failure of a major transmission component (~60,000 to 120,000 km) may raise questions regarding reasonable durability regardless of whether factory warranty has expired.
The ACL allows affected consumers to seek remedies from manufacturers for failure to comply with statutory guarantees.
The information on this website regarding Australian Consumer Law is provided for general educational purposes only and does not constitute legal advice.
A component failure does not automatically mean a breach of Section 54 has occurred in every circumstance. Each vehicle case must be assessed on its individual merits, taking into account vehicle age, mileage, servicing history, and diagnostic evidence.

An account of the delays, disruption, and communication hurdles experienced during a goodwill claim
A 2019 Tiguan (95,616 KM, full logbook history) triggered a transmission warning code. The owner contacted customer care with complete logbook records and requested advice on claims procedures.
The dealership confirmed a Mechatronics control unit fault. However, initial advice indicated the manufacturer would cover parts only, attempting to pass labour costs onto the owner. Customer care issued repeated automated delay messages.
Left without transport for over three weeks, the owner was forced to manage daily commutes with a 4-year-old child on public buses and trains while waiting through repeated 48-hour delay promises. The owner formally referenced ACL statutory guarantees.
After 33 days of back-and-forth communication, full repair coverage was finally authorized. While the repair cost was covered, the case illustrates the heavy disruption and communication barriers owners often face.
Verify that your diagnostic scan clearly logs specific transmission fault codes from an authorized service scanner.
Keep written records of every email, call date, and dealer conversation during the repair period.
Politely reference Australian Consumer Law while recognizing each claim is evaluated on individual vehicle history.
