Bmw Software Fix

With 2016 BMW 740i and 3 series sedans, the vehicle may run rough or hesitate when accelerating from a stationary position. Code FC 21A02D may be stored in DME fault memory (combustion control: valve lift correction when at idle). This is due to a software error in the DME. Update the vehicle software using ISTA 4.27.10 or higher.

threaded nut replaces the original selftapping stamped-steel nut. Note that if the shield is missing, carefully inspect the spare tire for heat-stress damage. The diagram shows the spare tire heat shield hold-down screw, behind exhaust, at 1; the spare tire heat shield at 2; the heat shield nut (behind the exhaust pipe) at 3; and the spare tire, 4.

Lincoln Fuel Odor

Some 2014 Lincoln MKT and MKS vehicles equipped with a 3.5L gasoline turbocharged direct injection (GTDI) engine and built on or before Feb. 2, 2014, may exhibit a raw fuel type odor most noticeable near the intake manifold. Remove the intake manifold and replace the high-pressure fuel tube. It Is not necessary to remove the fuel injection pump to perform this procedure. You will need the following parts:

Matching Ocv To Head

• High pressure fuel tube assembly: AA5Z-9J323-E

• Intake gasket set: AA5Z-9439-A

Chrysler Minivan Rattle

This bulletin applies to 2008-2016 Chrysler Town & Country vehicles. An abnormal rattle may be heard from the spare tire heat shield near the exhaust. If the heat shield is missing, replace it. If loose, or when replacing the shield, use the upgraded threaded hex nut to secure the shield and tighten to 35 in-lbs. This

In all Kia vehicles equipped with 2.4L Theta I & II engines, the correct OCV (oil control valve) must be matched with the proper cylinder head when servicing and/or replacing the cylinder head or the OCV. It is possible to receive a superseding cylinder head that may require a different OCV. The technician must visually identify the geometry of the oil port of the new cylinder head and compare it to the old cylinder head. The superseded head has slotted oil ports, while the superseding head has circular oil ports. If the cylinder head to be installed has circular oil ports, order the latest OCV, P/N 24355-2G500 intake or 24375-2G500 exhaust. If the oil ports are slotted, order the older OCV.

Toyota Rav4 Converter Shudder

Some 2013-2015 Toyota RAV4 vehicles may exhibit a brief shudder intermittently under light loads between about 25 and 50 mph.

The torque converter and ECM logic has been modified to reduce the possibility of this concern.

Drain the STF from the transaxle. Remove and replace the torque converter. With the transaxle installed in the vehicle, remove the transaxle oil pan. Remove and discard the two oil pan magnets and clean the inside of the pan by wiping with a clean cloth only. Do not use any chemical cleaners inside the pan. Install four new magnets as shown in the photo. Reinstall the pan with a new gasket. Reinstall the drain plug using a new drain plug gasket and refill with ATF. Flash reprogram the ECM using software version 15.30.027 or later.

Acura Radar Grille Check

This applies to all Acura vehicles equipped with CMBS (collision mitigation braking system) where the millimeter wave radar looks through the front grille upper molding. If the CMBS indicator is on with DTC P2583-97 (dust or dirt on the wave radar possible), before going into heavy troubleshooting, make sure the vehicle does not have a non-CMBS front grille upper molding. This could happen if the vehicle has had some body work done and a non-CMBS molding was installed. The millimeter wave radar can’t see through that type of molding. The back surface of the CMBS front grille upper molding is dull black. The molding for the non-CMBS is metallic looking. Replace the molding if necessary.

Chevy Glow Plugs

Certain 2018-2019 Chevy Silverado trucks equipped with a 6.6L diesel engine may have a condition that could cause the engine glow plugs to fail. If this occurs, the MIL will illuminate and DTCs will set. The engine may be hard to start or may run rough immediately following engine start.DTCs may include P0671-P0678 (glow plug circuit/open); P1338-P133F (glow plug offset exceeded learning limit) and/or P06C5-P06CC (glow plug incorrect). Replace the glow plugs on bank 1 and/or bank 2 as needed.

FORD F-150 OIL CONSUMPTION

Some 2016-2017 Ford F-150 trucks equipped with a 2.7L GTDI engine and built on April 1, 2016, through Jan. 1, 2017, may exhibit white or blue smoke from the exhaust, and rough idle in Neutral and Park at normal op- erating temperatures or after a hot restart. The MIL may be on. DTCs P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0316, P0524 and/or P06DD may be set along with excessive oil consumption (oil consumption may be one quart in less than 3,000 miles. If DTCs P0524 and/or P06DD are not stored in the PCM, replace the cylinder heads.

If these DTCs are stored, check oil level. If level is not within the minimum and maximum marks on the indicator, add oil to correct level and run the engine to normal operating temperature, and check to see if oil pressure is within specification. If oil pressure meets specs, replace the cylinder heads. If oil level was initially within spec, run the engine to check oil pressure. If pressure is not within spec, Ford recommends replacing the long block assembly.

Honda Navigation Precaution

If you’re servicing a Honda vehicle equipped with the hard disc drive (HDD)based navigation system and plan to replace a HDD-based audio-navigation unit, even for an audio-related problem, make sure to transfer the HDD to the replacement unit. Replacement units do not come with HDDs. If you forget to transfer the HDD and power up the replacement unit without it, you’ll see an error message, which means the unit is now damaged, and another replacement unit will be needed
