Service bulletins for the 2008 Volkswagen Passat

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

TT5512032023-07-10. Service bulletin. LATCHES/LOCKS/LINKAGES:ELECTRONIC LOCK/LATCH ACTUATOR; STRUCTURE:FRAME AND MEMBERS; ELECTRICAL SYSTEM:INTERIOR LAMPS/BULBS. When diagnosing a power rear lid that will power open but will not power close, check operation of luggage compartment lamp W3. Lamp should be on with rear lid open and off with rear lid closed.
TT5014012023-07-10. Service bulletin. WHEELS; TIRES. The use of tire dressing gives your tires that shiny finish that completes the image of a clean (new) vehicle. There are many different tire dressing products available. When choosing a product please pay close attention to its contents. Always use a water based product.
TT4609042023-07-10. Service bulletin. PARKING BRAKE:ELECTRICAL:SWITCH; ELECTRICAL SYSTEM; PARKING BRAKE:ELECTRICAL:CONTROL MODULE; PARKING BRAKE. If fault code 03200 or 16352 is present in the Electromechanical Parking Brake (EPB) module, it may be due to the switch and module not being synchronized.
TT4509032023-07-10. Service bulletin. AIR BAGS; STEERING; SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE; ELECTRICAL SYSTEM; STEERING:RACK AND PINION:RACK. If, after replacement of the steering rack, fault code 01309 008 is set in the ABS/ESP module only, follow the test plan in GFF for Driver Steering Recommendation (DSR) or channel 3 activation. If the test plan fails to clear the fault, follow the direction below using Vehicle Self Diagnosis in Address Word 44 - Steering Assistance
TT4508022023-07-10. Service bulletin. SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING; UNKNOWN OR OTHER. Fault code 02543 000 ?Brake Vacuum Sensor no Display? may be encountered in the ABS module. This may be caused by the hydraulic brake boost function (HBV) in adaptation value 61 being turned off (value = 0). All Passat Wagons (including 4motion) and 3.6L equipped sedans with front drive should have this function turned on (value = 1). Change the adaptation value and verify the fault has cleared. Additionally, it may be necessary to lock the vehicle and allow the modules to go to sleep to clear the fault.
TT45061222023-07-10. Service bulletin. ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER:SENSOR/SENDING UNIT; SERVICE BRAKES, AIR:ANTILOCK:CONTROL UNIT/MODULE. Use the following procedure to diagnose active wheel speed sensor complaints
TT201301a2023-07-10. Service bulletin. UNKNOWN OR OTHER; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM); FUEL SYSTEM, OTHER. To clear static ECM fault P1250 ?Fuel Level Too Low?, add fuel to vehicle and complete a road test of at least 10 miles. Simply adding fuel without completing a road test may not allow fault to clear.
TT2013012023-07-10. Service bulletin. FUEL SYSTEM, OTHER; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM); UNKNOWN OR OTHER. To clear static ECM fault P1250 ?Fuel Level Too Low?, add fuel to vehicle and complete a road test of at least 10 miles. Simply adding fuel without completing a road test may not allow fault to clear.
TT2009062023-07-10. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING:ENGINE:DIESEL; FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Use the diagram below to test the N75 Solenoid Valve in the event of a turbocharger fault code such as P0299 or P0234. This applies to Mechanical Injection Style Diesel Engines, Pumpe Duse Style Diesel Engines and the new Common Rail Style Diesel Engines.
TT20061012023-07-10. Service bulletin. SERVICE BRAKES, AIR:SUPPLY:PRESSURE GUAGE; SERVICE BRAKES, HYDRAULIC. If you have a complaint of DTCs for the low side fuel pressure being out of specification (e.g. P310B), check the fuel pressure with BOTH a mechanical gauge and by the display in Measured Value Block 103. The readings should be 1 bar higher in the MVB due to reading atmospheric pressure + fuel pressure. If the mechanical gauge reading is within specification BUT the MVB 103 reading is not 1 bar higher, check for a possible faulty G410 Low Fuel Pressure sensor.
TT1913022023-07-10. Service bulletin. ENGINE AND ENGINE COOLING. Inspect the water pump for signs of contact with engine oil. Engine oil may cause the water pump gasket to swell, which may lead to a coolant leak. If water pump replacement is necessary, ensure that any engine oil is thoroughly cleaned off, prior to water pump installation. Please note that when replacing the water pump or opening the cooling system, there is a special bleed procedure that has to be performed. Vacuum bleed the cooling system for 10 minutes. Start the engine and let idle until the thermostat opens and the cooling fan runs, before driving vehicle or raising engine RPM.
TT131301a2023-07-10. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. When servicing the timing chain sprocket or removing the vibration damper, be aware that one bolt holds both the vibration damper (harmonic balancer) and the crankshaft timing chain sprocket to the crankshaft. Once the damper is removed, the crankshaft should not be rotated unless special tool spacer T10368 has been installed. The crankshaft timing chain sprocket and spur gear drive on the crankshaft have a coupling that must be seated correctly during assembly. Failure to install special tool spacer T10368 before rotating engine will cause the engine to skip time and bend valves.

TT011401a2023-07-10. Service bulletin. POWER TRAIN; ENGINE AND ENGINE COOLING. Install a vacuum gauge on the dipstick tube and check crankcase vacuum at idle. Compare to a known good vehicle. If the vacuum reading is lower than the comparison vehicle, visually inspect for oil leaks between the engine and the transmission. Smoke test the crankcase by connecting the EVAP smoke machine to the dipstick tube and inspect for leaks at the rear main seal (this will limit pressure to 2 PSI). DO NOT apply shop air to the dipstick tube or the crankcase. If a rear main seal leak is identified, replace the seal. Once replaced, recheck crankcase vacuum at idle. If low, check for additional oil leaks and verify crankcase breather operation (repairing as necessary). Erase the faults and road test 10 miles to recheck operation.
