VW Tiguan
Biturbo diesel with 240 hp and two-stage charging. Very strong pull, but complex due to biturbo technology. Wastegate and pressure sensors are typical wear items.
BiTurbo diesel with bite
240 hp from the 2.0 BiTDI and 500 Nm — fastest diesel in the segment, 0–100 in 6.5 seconds.
Engine Weaknesses 5
The CUPA 2.0 TDI BiTurbo is affected by the Dieselgate recall. The ECU detected test bench conditions and only activated full emission control during tests.
Symptoms: Higher NOx emissions in real driving, possibly changed throttle response after software update
The CUPA (184 hp FR variant) EA189 in the Leon 5F is part of the VW diesel emissions scandal. The mandatory software update increases EGR activation. FR owners who drive sportily report increased fuel consumption after the update.
Symptoms: After update: EGR fault, black smoke, power drop, fuel consumption +10–15%
The EA189 CUPA frequently shows faulty turbo pressure sensors (P2563/P2564). The higher boost of the FR model stresses the sensor more. On failure: limp mode with reduced power.
Symptoms: Engine warning light, fault code P2563/P2564, power drop during boost build-up, whistling from turbo
The boost pressure sensor of the CUPA 2.0 TDI BiTurbo fails and activates limp mode. Sporadically no boost pressure despite intact turbochargers.
Symptoms: Engine enters limp mode, P0299 boost pressure too low, power loss at low rpm
The CUPA 1.5 TSI evo is equipped with an OPF that cannot fully regenerate with predominantly short-trip use and clogs. Result: engine warning light, increased consumption, power loss.
Symptoms: Engine warning light, increased fuel consumption, power loss, OPF warning message
Vehicle Weaknesses 10
VW recalled approximately 700,000 Tiguan and Touran vehicles worldwide due to a light strip in the panoramic roof through which moisture can enter and cause a short circuit, creating a fire risk.
The pre-charge pump of the Haldex coupling (Gen 5) becomes blocked by clutch debris in the oil because VW service schedules don't include a filter change by default. Result: four-wheel drive drops out. Repair: 400–3,500 €.
Many Tiguan II owners report premature brake disc wear from as early as 30,000 km. A recall covered vehicles with front discs cast too thin (production January 2018). Repair per axle: 400–700 €.
The electronic parking brake on the Tiguan II can unexpectedly fail to release or engage. Causes include a faulty control unit or broken wiring in the harness running through the centre console. Repair: 300–1,000 €.
The air conditioning stops cooling adequately due to refrigerant loss through leaking seals or condenser damage from stone chips. Compressor failure announces itself with rattling. Repair: 300–1,000 €.
On the Tiguan AD, the electric tailgate spindle drives fail. Often a single uncontrolled grab of the closing tailgate is enough to damage the motor. One motor replacement costs approximately €300–500; both sides approximately €1,000.
On the Tiguan II, several driver assistance systems sporadically drop out simultaneously with warning messages (Auto-Hold, ACC, EPB unavailable). The cause is often a voltage dip in the electrical system or a USB control unit fault.
Rear control arms show corrosion and worn rubber bushings. Cases documented at 100,000–130,000 km, with rust appearing earlier in salted road conditions. Repair for both control arms: approx. 350 €.
The Tiguan II navigation system (Discover Pro/Discover Media) is notorious on early models for extremely slow response times and occasional freezing. DAB radio reception is also unreliable.
On the Tiguan II, knocking and creaking noises occur at cold temperatures and full steering lock. VW describes this as 'normal operating noise', but affected customers report repeated workshop visits.
