Problem 1
Volkswagen Tiguan: DPF, AdBlue, or lambda-sensor faults on the 2.0 TDI
What goes wrong
Short trips block the particulate filter; the lambda sensor and (on later cars) the AdBlue system are known to fail from about 100,000 km.
How to check it yourself
Read the codes and live data: DPF soot load and pressure, lambda readings, and AdBlue system status.
The usual fix
Regenerate or clean the DPF, replace a failed lambda sensor, and repair the AdBlue part named by the codes. Dealer software updates solved many AdBlue faults.
Signs: Loss of power, Check engine light
Fault codes: P2002, P2463, P0130, P2237, P20EE
Problem 2
Volkswagen Tiguan: High oil consumption on the 2.0 TSI
What goes wrong
Early EA888 engines used piston rings that clog up, which can raise oil consumption to around a litre per 1,000 km.
How to check it yourself
Fill to max and measure top-ups over 1,000 km; rule out leaks and a faulty PCV (crankcase breather) valve first.
The usual fix
Replace a faulty PCV valve if found. Real ring wear needs updated pistons and rings, which is an engine-out job; compare the cost with the car’s value.
Signs: Blue smoke, High oil consumption
Problem 3
Volkswagen Tiguan: Timing chain and tensioner wear on the early 1.4 TSI
What goes wrong
The early chain-driven 1.4 TSI stretches its timing chain and wears the tensioner.
How to check it yourself
Listen for a rattle at a cold start and read cam/crank correlation codes.
The usual fix
Replace chain, tensioner, and guides with updated parts before the chain jumps.
Signs: Rattle on cold start, Rough idle, Check engine light
Fault codes: P0016, P0017
Problem 4
Volkswagen Tiguan: Water in the cabin from blocked sunroof drains
What goes wrong
The drain tubes at the corners of the panoramic roof block with dirt, so water overflows into the headlining, A-pillars, or footwells.
How to check it yourself
Open the roof and pour a little water into the drain channel at each corner; it should run out under the car within seconds.
The usual fix
Clear the drains with a flexible trimmer line or low-pressure air, and dry the carpets fully to protect the wiring underneath.
Signs: Water leak into cabin
