Service bulletins for the 2018 Porsche Macan

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.

Bulletins, newest first
122-F4U4P-042018-04-23. Service bulletin. ELECTRICAL SYSTEM. Model Line: Cayenne (92A) Macan (95B) Concerns: AGM starter battery (referred to below simply as ?battery?) Situation: Customer complaints concerning battery-related topics Recurring customer complaints concerning topics relating to battery capacity and quality.
122-A6Z3V-032018-03-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:GAS RECIRCULATION VALVE (EGR VALVE). Subject: Intake valves and intake ports Information: Carboned-up valves in the engine can be reworked and cleaned using cleaning equipment. If there is a complaint about knocking combustion, e.g. during acceleration at high load, the condition of the intake valves and portsmust be checked before doing any other work. If the check shows that the intake valves and intake ports have carbon deposits and are dirty, they must be cleaned using the VAS 294 011 - cleaning unit. There should be no need to replace the components. Date of Introduction: The VAS 294 011 - cleaning unit can be ordered immediately for dealers. Remedial Action: The VAS 294 011 - cleaning unit is used for cleaning carboned-up intake valves and intake ports. Compressed air is used to spray a special granulatemixture into the intake port,where it loosens and removes carbon build-up. The dirty granulate is extracted during spraying using an industrial vacuum cleaner.
122-L7P4X-032018-03-13. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); POWER TRAIN. The "transfer case" is designed as an active all-wheel drive system that is dynamically adapted to the respective driving state. Power transmission between the front and rear axle is controlled electronically via the "all-wheel drive servomotor (transfer case)" and themulti-plate clutches integrated in the transfer case. ? On all-wheel drive vehicles, the drive train can become strained at low speeds and when the steering is turned sharply when "Off-roadmode" is activated, depending on design. ? Under extreme conditions, the drive train can also become strained when "Off-roadmode" is deactivated. ? Customers with little experience with all-wheel drive vehicles can interpret this behavior as a fault, which in turn can result in incorrect diagnoses in the workshop. Remedial action: Customer complaint to be checked: ? Rough-running engine or ? thevehicle vibrates or ? theengine jerks under load/during acceleration.
122-F8U4Z-022018-02-12. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Subject: Air-conditioning control unit (also control panel/switch console) Symptom: When starting the vehicle, an unsuitable air conditioning setting is preset in the rear air-conditioning control unit. Only air conditioning settings from driver's key 1 are stored and applied to all other driver's keys. Cause: The last air conditioning settings from driver's keys 2-4 cannot be read out quickly enough. The last stored setting from driver's key 1 is used.
122-X2M2D-012018-01-29. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Symptom: Symptom 1: Right headlight has interior condensation. Symptom 2: One or both headlights has/have interior condensation Remedial action 1: The breather hose 95B.941.560.B (without corrugated hose) must be replaced by the breather hose 95B.941.560.C (with corrugated hose). It is important to check that the breather hose is routed without kinks.
122-H5C4J-122017-12-14. Service bulletin. SERVICE BRAKES, AIR:ANTILOCK:WHEEL SPEED SENSOR; SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RING. Information: It is possible that a faulty wheel speed sensor can be the root cause of the multiple warnings. Check the fault memory for the following types of faults for one or more wheel speed sensors. * Sensor Fault * Sensor Electrical Fault * Sensor Implausible Fault
122-N4G6E-092017-09-14. Service bulletin. EQUIPMENT; STEERING. Symptom: Customers complain about disturbing noises coming from the footwell area on the driver's side while steering. Cause: The surface of the foam rubber seal in the sealing sleeves starts to wear and crumble due to high temperatures. This effect causes the reported noise. Remedial Action: In the event of a customer complaint on a vehicle that: * was produced before the date of introduction (June 02, 2016), replace the existing intermediate steering shaft with a new, modified intermediate steering shaft with felt ring, see Workshop Manual - Workshop Manual '482819 Removing and installing intermediate steering shaft', * was produced after the date of introduction (June 02, 2016) or was already replaced by the new type of intermediate steering shaft (with felt ring),
122-H7B7W-092017-09-14. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Information: Very small leaks may not be found on a normal inspection. Extra effort to locate these leaks is required.
122-X4P2F-092017-09-14. Service bulletin. EQUIPMENT:ELECTRICAL. Information: Due to an incorrect parameter set for both control units for PDCC, the PASM control unit can detect non-existent swaying of the chassis under certain driving conditions. As a result, the PDCC system is deactivated and the chassis is switched to Sportmode. If this happens, the yellow warning message "Chassis system fault - Visit workshop, Adapted driving permitted" will be displayed in the instrument cluster and the vehicle then permanently behaves like a chassis in Sport mode. Remedial Action: Re-program control units for PDCC using the PIWIS Tester with software version 36.000 (or higher) installed.
