P1736 on Audi by model: symptoms, diagnosis and fix
The SQ2's 7-speed S tronic dual-clutch (the wet-clutch DQ381 / 0GC unit shared across MQB-platform A3/Q3/TT and VW Golf GTI/R) is generally durable but is widely reported to develop jerky or hesitant engagement at low speed and in stop-start traffic, harsh shifts when hot, and occasional limp-mode events. Owners describe a jolt/shunt when pulling away or in 1-2 / 2-1 changes. Root causes traced in the field include mechatronic valve/solenoid faults, clutch position-sensor faults, K1 clutch-pack wear, and degraded/contaminated gearbox fluid, especially where the DSG oil service has been skipped.
Common Symptoms
- Jerky or harsh shifts at low speed
- Shunt/jolt when pulling away
- Hesitation before gear engages
- Harsh shifting when transmission is hot
- Limp mode / restricted speed
- Gearbox malfunction warning
How to Fix
First step is a proper DSG fluid-and-filter service (the wet-clutch unit needs periodic transmission oil changes — many owners do it around 40k miles even though intervals can be longer). Have the TCU scanned for stored codes; sensor or mechatronic valve replacement and re-coding/adaptation resolves many cases, while severe cases need a full mechatronic unit or clutch-pack replacement. Insist on a software/adaptation update at the dealer for driveability complaints.

Frequently asked questions
What does P1736 mean on a Audi?
P1736 stands for "Shift Control System (Manufacturer Specific)." P1736 is a manufacturer-specific transmission code (common on Hyundai and Kia, where it indicates a shift motor / shift control circuit problem, often 'Shift Motor Open'). It points to a fault in the system that controls gear shifting — typically the shift control motor or its circuit on transfer-case or transmission applications. Because P1-series codes vary by manufacturer, the exact meaning should be confirmed against the specific vehicle's service information. Symptoms usually include shifting problems, getting stuck in gear, or a transmission/4WD warning light. On Audi it is documented across 1 model: SQ2.
What are the most common causes of P1736?
The most common causes of P1736 are: Faulty shift control motor or actuator, Open or shorted wiring in the shift motor circuit, Corroded or damaged connector at the motor/control unit, Failed transmission or transfer-case control module, Worn or seized internal shift mechanism, Poor ground or power supply to the shift motor, Blown fuse or relay feeding the shift control circuit. The specific cause varies by vehicle.
How much does it cost to fix P1736 on a Audi?
Published repair estimates on Audi range from $300 to $3,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
