P1735 on Audi
Shift Control System (Manufacturer Specific)
P1735 on Audi vehicles indicates shift control system (manufacturer specific). Au7o has documented this code across 1 Audi model — most commonly on SQ2. P1735 is a manufacturer-specific transmission code related to the shift control system (definitions vary by automaker, but it commonly references a gear/range selector or shift-control issue, often '1st gear' or a shift solenoid/range circuit). Because it's enhanced rather than generic, its exact meaning depends on the vehicle make. Broadly, it means the transmission control module detected that a commanded gear or shift action didn't occur as expected. Symptoms can include harsh or missed shifts, slipping, no gear engagement, or a transmission in limp mode. Always confirm the precise definition against the specific manufacturer's service data. Typical repair costs on Audi range from $300 to $3,500, depending on the specific model and root cause.
Common Causes of P1735
- •Faulty shift solenoid in the affected gear/range circuit
- •Low, dirty, or degraded transmission fluid
- •Wiring or connector fault in the shift-control circuit
- •Internal valve body or hydraulic pressure problem
- •Worn clutch or band for the affected gear
- •Faulty transmission range/position sensor
- •Transmission control module fault (less common)
P1735 on Audi by Model
Audi SQ2(1 issue)
- S tronic (DQ381) 7-speed wet-clutch transmission: jerky low-speed shifts, hesitation and limp mode2019-2024
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.
