2017 Volkswagen Tiguan Problems: 4 Known Issues

On the 2009-2017 Volkswagen Tiguan, volkswagen's 2.0T TSI engines of the CCTA/CBFA generation (and the earlier BPY FSI) run their intake manifold runner flaps through a vacuum-operated regulator valve, with a position sender reporting flap angle back to the ECM. Volkswagen issued Technical Bulletin 24 17 09 (2045138), filed with NHTSA, specifically listing P2004, P2014 and P2015 together for all 2006-2008 2.0T BPY and all 2008-2016 2.0T CCTA/CBFA engines, and it identifies two distinct root causes that a parts-cannon repair will miss. The first is purely pneumatic: the small vacuum lines and the plastic vacuum tee that feed the intake manifold flap regulator valve become restricted by debris from production or accumulated with mileage, and the lines themselves can be twisted, kinked or mis-routed against hot components. With a restricted vacuum supply the flaps cannot reach the commanded position in the time the ECM expects, and the position feedback goes out of the expected window - the fault stores even though sensor and manifold hardware are both intact. The second cause is mechanical and terminal: inside the manifold, the flap carrier plate separates from the regulator valve linkage, so the actuator moves but the flaps do not follow. VW's bulletin gives technicians a specific pass/fail test for this and calls for manifold replacement when the carrier plate separates or flap adaptation fails. Drivers typically report a check engine light, a flat spot and loss of pull below about 3,000 RPM, slightly worse mileage, and on some cars a rough or hunting idle. Volkswagen also extended intake manifold coverage to 10 years or 120,000 miles from the original in-service date on certain 2015 model year Tiguan, CC and Eos vehicles with CBFA/CCTA engines, so a VIN check at a dealer is worth doing before paying out of pocket.

On the 2009-2017 Volkswagen Tiguan, owners of first-generation Tiguans with the 2.0 TSI report the turbocharger diverter (recirculation) valve failing and the engine not holding boost. Applies to: 2009-2017 Volkswagen Tiguan with the 2.0 TSI EA888 CCTA or CPLA engine.

On the 2009-2021 Volkswagen Tiguan 2.0L TSI (EA888), volkswagen extended warranty coverage for failed engine water pumps, thermostats and thermostat housings on Tiguans under class-action settlements, including a share of the cost of engine damage directly caused by such a failure. Applies to: Tiguans in the settlement classes: 2009-2014 Tiguan (VWP-19-08: water pump, 10 years/100,000 miles) and certain 2014-2021 Volkswagen models including Tiguan (VWP-22-06: water pump, thermostat and thermostat housing, 8 years/80,000 miles). Both periods count from the original in-service date, so coverage may already have ended. Only a Volkswagen dealer can confirm eligibility by VIN.

On the 2009-2017 Volkswagen Tiguan, the combined door latch and central-locking actuator used on the 2009-2017 Tiguan (shared with Passat/CC of the era) fails through its internal microswitches and drive motor. Symptoms start intermittently - one door does not respond to the fob or interior switch, the driver's door will not open from outside, the cluster shows a door open with all doors shut, interior lights stay on, or the alarm goes off randomly at night - and then the door stops locking altogether. Owner threads on VWVortex, MyTiguan and Tiguan Forums UK trace it to the latch module rather than the fob or body control module.
