Engine will crank but not start. There is no communication with the integrated fuel module (TFE) whendiagnosing with ISTA. The following two fault codes will be stored in the DME: 032B43 - Low fuel pressure system, electric fuel pump: pressure value too low CDA594 - Message (- 0x33E) missing, receiver DME, transmitter TFE

Customers may state that the alarm system (DWA) is not active after locking their unoccupied vehicle. Depending on the vehicle’s equipment and settings, no acoustic or optical confirmation (folding the mirrors/blinking confirmation) is noticeable. Additionally, the red anti-theft alarm LED in the interior mirror does not briefly flash every 2 seconds, indicating the alarm is armed.

Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form.

Components: SERVICE BRAKES, AIR:DISC · STEERING: STEERING WHEEL/HANDLE BAR. Confirm detailed applicability in the original document.

Discharged Battery Energy Diagnosis Must Be Performed: The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle "discharged battery" complaints. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair.

Power Reduction FC2A82 Intake VANOS and/or FC2 A87 Exhaust VANOS Camshaft Fault: The "Service Engine Soon" (MIL) lamp is illuminated and engine power reduction is perceived. This situation can occur after driving for some time with the engine at full operating temperature. If the ignition is cycled the engine then usually performs normally.

Various Electrical Problems Caused by Water Ingress. Water ingress into the luggage compartment may cause various electrical problems or faults associated with the MPM (Micro Power Module); PDC (Park Distance Control); M-ASK (Multi-Audio System Controller); CCC (Car Communication Computer); CID (Control Information Display); TCU (Telematics Control Unit); LOGIC-7 (Top Hi-Fi); RDC (Tire Pressure Monitor) or SDARS (Satellite Radio Receiver) control modules. In most cases, the water collects in the spare wheel recess. CAUSE: Insufficient sealing may allow water to enter the luggage compartment due to the vacuum generated while driving.

Components: ELECTRICAL SYSTEM · STRUCTURE. Confirm detailed applicability in the original document.

NAVIGATION SYSTEM: REPORTING MISSING OR INCORRECT ROAD MAP DATA: The route guidance is inaccurate and therefore irritating to the customer; or it is not possible to locate certain addresses, for instance:

Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits This Service Information bulletin supersedes SI B07 03 14 dated October 2015.. Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
