— The 7-speed DSG (DQ200) on pre-2020 TSI and TDI variants is notorious for mechatronic unit failures. Symptoms: shuddering at low speeds, delayed gear engagement from standstill, jerky 1-2 and 2-3 shifts, or the car refusing to go into gear. If you notice any of these during a test drive, walk away — a mechatronic unit replacement costs ₹40,000-80,000. Note: 2020+ models use a 6-speed torque converter AT which is far more reliable.

— The 1.2L TSI turbo engine used in GT TSI variants (pre-2020) is known for timing chain tensioner failure. A metallic rattling noise on cold start that goes away after 10-20 seconds is the classic symptom. If left unaddressed, the chain can skip teeth and cause catastrophic engine damage. This is an expensive preventive replacement — but ignoring it risks the entire engine.

— If both the check engine light and EPC (Electronic Power Control) warning light are on simultaneously, it indicates a serious engine management issue. On TSI models, this often points to a failing turbo wastegate actuator, ignition coil failure, or catalytic converter issues. On TDI models, it could be injector or EGR valve failure.
