Mk6 (AW, Europe) · 2017–present
1.0 MPI · 80 hp · 1.0 TSI · 110 hp · 1.5 TSI · 150 hp · GTI 2.0 TSI · 207 hp
Known problems
- Worth watching usually from 37,000 mi (60,000 km)
DQ200 dry-clutch DSG judder
Symptoms: shudder pulling away, jerky low-speed shifts, occasionally a gearbox warning
What to do: Automatic TSI cars use the 7-speed dry-clutch DQ200, which wears faster in traffic. Change the gearbox oil on schedule and diagnose judder early.
- Worth watching usually from 50,000 mi (80,000 km)
1.0 TSI carbon buildup on intake valves
Symptoms: rough idle, hesitation, mild power loss and higher fuel use over time
What to do: The direct-injection 1.0 TSI accumulates intake-valve soot, worse on short-trip cars. If it runs rough, have the valves cleaned; quality fuel and occasional longer runs slow it.
- Worth watching usually 50,000–87,000 mi (80,000–140,000 km)
Water pump / thermostat plastic housing coolant leak
Symptoms: slow coolant loss, damp residue near the belt side, occasional overheating warning
What to do: The integrated plastic water pump/thermostat module warps and leaks with heat cycling. Watch coolant level and replace the assembly at the first leak, ideally with the timing belt.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | shorten under short-trip use |
| Cabin (pollen) filter | every 19,000 mi (30,000 km) | — |
| Air filter | every 37,000 mi (60,000 km) | — |
| DSG oil change important | every 37,000 mi (60,000 km) | DQ200 dry-clutch 7-speed on automatic TSI cars |
| Spark plugs | every 37,000 mi (60,000 km) | petrol only; shorter on the GTI |
| Timing drive service important | every 75,000 mi (120,000 km) | the TSI/MPI (EA211) are belt-driven interference engines (~120,000 km, replace the water pump with the belt); the GTI EA888 is chain-driven |
| Brake fluid important | every 24 months | — |
Sedan / Liftback (RU) · 2010–2022
1.4 TSI · 125 hp · 1.6 MPI · 105 hp · 1.6 MPI · 110 hp
Known problems
- Worth watching
CFNA exhaust manifold cracking
Symptoms: ticking/exhaust leak noise, smell of exhaust, crack between the 2nd and 3rd cylinders
What to do: The exhaust manifold on the CFNA can crack between cylinders 2 and 3. Have any exhaust leak inspected; welds can reopen, so replacement is the durable fix.
- Worth watching usually 19,000–62,000 mi (30,000–100,000 km)
CFNA 1.6 cold-start knock
Symptoms: progressive knocking / rattle after a cold start, sometimes appearing at low mileage
What to do: Many early 1.6 MPI CFNA engines (to about 2015) develop a cold-start knock linked to piston/con-rod wear and low idle oil pressure. Use the correct oil, don't skip changes, and have a persistent knock inspected before it worsens.
- Worth watching usually from 50,000 mi (80,000 km)
Water pump / thermostat plastic housing leak (TSI / CWVA)
Symptoms: slow coolant loss, damp residue near the belt side of the engine
What to do: On the belt-driven CWVA and 1.4 TSI, the plastic water pump/thermostat module can crack and leak. Monitor coolant level and replace the assembly with the timing belt.
- Good to know usually from 19,000 mi (30,000 km)
CWVA 1.6 oil consumption
Symptoms: gradual oil use, roughly up to 0.4 L per 1,000 km on some cars
What to do: The later 1.6 MPI CWVA is much more robust than the CFNA but some cars use a little oil. Check the level regularly and top up as needed; heavy consumption warrants a ring/valve-seal check.

| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | shorten to ~10,000 km in dusty / short-trip Russian conditions |

Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
