VW Polo
Base diesel in the Polo VI. 80 hp adequate for city driving. Short-lived variant, no longer available after 2019.
Efficient commuter engine
80 hp TDI in the AW Polo — sensible, economical. Useful for motorway commuters, the wrong choice for driving fun.
Engine Weaknesses 5
The DGTD 1.6 TDI 70 kW in the Seat Ibiza KJ is susceptible to DPF clogging with short-trip use due to the small engine displacement. Regularly free the vehicle on the motorway.
Symptoms: DPF warning light, power reduction, increased fuel consumption
The DGTD, like all EA288 small diesels, tends to EGR coking with predominantly city driving. EGR valve cleaning or replacement may be needed from 80,000–100,000 km.
Symptoms: Power loss, MIL, black exhaust smoke
The electronically controlled coolant pump on the EA288 1.6 TDI can fail internally: shut-off cap jams in the closed position and prevents coolant circulation.
Symptoms: Howling noise from coolant pump, temperature spike, coolant temperature gauge suddenly rising, MIL
On the DGTC 1.6 TDI EA288, the EGR cooler cracks internally and coolant enters the exhaust stream where it burns. As no puddle forms, the problem is often detected late.
Symptoms: Dropping coolant level without visible leak, white smoke from exhaust, sweet smell in heater, overheating risk
With direct injection, the DGTC intake valves are not flushed and coke up. From approx. 80,000 km power drops, idle becomes rough and consumption rises.
Symptoms: Power loss, rough idle, increased fuel consumption, stumbling
Vehicle Weaknesses 10
Recall for model years 2016–2020: The double seatbelt buckle on the rear bench can unintentionally open when fully occupied. VW retrofits a spacer (action codes 69X5/69X7/69BB). Free at authorised dealer.
TÜV reports show unusually frequent steering joint defects on the Polo VI (AW). Problems typically appear from 5–6 years of vehicle age. Steering rack or joint repair costs €500–1,400.
On the Polo AW with 1.0 engine, the rear drum brakes seize after rainy periods or extended standing. Drums are rarely loaded so rust is barely worn off. Regular cleaning and lubrication necessary.
Dipped beam failures are reported unusually frequently on the Polo AW according to TÜV statistics. Both bulb and control unit problems are documented. Repair costs vary widely depending on cause (€50–600).
Stop-start function, rain sensor wipers and central locking occasionally cause problems on the Polo AW. Usually resolvable under warranty or goodwill. Repair costs €100–400 if out of warranty.
Front axle control arm bushings can wear out sooner than expected and lead to banging noises over bumps. TÜV cites worn bushings. Repair costs €150–500 depending on extent.
Despite improved corrosion protection compared to its predecessor, some Polo AW examples show early rust bubbles at door lower edges and sill areas, especially at untreated stone chip damage.
The MIB2 infotainment system occasionally freezes or restarts. Bluetooth connection drops and app crashes are frequently reported. Software updates via authorised dealer may help.
Hinge noises from the front, especially on cold engine or over compression. VW has issued TPI 2062131/5 (silicone paste buffer) and TPI 2061277/1 (new gaiter from MY2021). Affects models up to MY21.
Rear brake squeal is typical for the Polo GTI AW. VW has issued a TPI (technical info) regarding brake 'mooing'. ATE Ceramic brake pads reportedly eliminate the issue completely.
