TT 21-13-012017-12-14. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Tech Tips (Equipped with Turbocharged Engine Turbocharger Replacement Tip): If mechanical damage is found to the turbocharger (e.g. damaged compression wheel, loose or broken shaft), it is not enough to just replace the turbocharger. This document informs the procedure of checks for damage.
V011316 20340462017-12-14. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:SOFTWARE. Technical Bulletin (Update Programming of ECM for Concerns of a Bump Sensation after Coming to a Stop): Current ECM programming may cause a bump after coming to a stop, which may be felt through the chassis of the vehicle. This concern is caused by the engine torque being slightly high when the transmission goes into Neutral Control. Neutral Control is designed to reduce load on the engine during idle, in order to decrease emissions. The production solution to this issue was improved software for smoother stopping.
V011317 20340122017-12-14. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:SOFTWARE. Technical Bulletin (Manifold Absolute Pressure Range / Performance Stored in ECM Fault Memory): Monitoring strategy for the manifold absolute pressure sensor is too sensitive, causing fault code P0106 to incorrectly set in the engine control module. The production solution to this issue was improved software. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.

V281303 20321162017-12-14. Service bulletin. ENGINE AND ENGINE COOLING. Technical Bulletin (Cylinder Glow Plug issues): During the initial glow phase, after switching the ignition "On", the ECM performs a check of the glow plugs through the glow plug control module, to ensure the correct glow plugs are installed. If the engine is cranked during this check, lowering the system voltage, the ECM may receive an incorrect reading and set incorrect glow plug faults. A production solution is already being implemented for this issue. This document discusses the "Fault Codes" necessary to diagnosis, and potential remedy of the issue. The fault codes for checking warranty coverage for servicing the vehicle are also available.
TT 17-12-022017-12-14. Service bulletin. ENGINE AND ENGINE COOLING. Tech Tips (Oil Leak From Oil Drain Plug Area After Oil Change and/or Drain Plug Replacement): This document informs an oil leak from around the oil drain plug noted after oil change, and/or drain plug replacement, may be caused by installation of incorrect drain plug.

TT 26-13-012017-12-14. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Tech Tips (Equipped with 2.0L TDI Engine - Engine Control Module Fault P2413 "Exhaust Gas Recirculation System Performance" Diagnosis Tip): When diagnosing ECM fault P2413 "Exhaust Gas Recirculation System Performance", pressure test turbo hoses for leaks and repair as necessary. Once repairs are completed, learned values in ECM must be deleted. Use VAS-PC Vehicle Self Diagnosis or ODIS Control module OBD to select Access Permission (or access authorization), then select Coding 2. Enter code 10008 when prompted. After code has been accepted, clear ECM fault code memory and then cycle key off and back on twice. Road test vehicle to ensure fault does not return.
V171302 20178132017-12-14. Service bulletin. ENGINE AND ENGINE COOLING. Technical Bulletin (Oil Consumption Measurement): Customer states oil consumption is higher than the Volkswagen oil consumption standard of up to 0.5 quarts per 600 miles, or 0.5 liters per 1000 km. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. This document informs of oil consumption tests to check a vehicles performance.
