Recall ID – NHTSA: 05V504000 – 2005-2006 X5

Summary

Some automatic equipped 2005-2006 X5 SAV’s were built with an incorrectly manufactured parking prawl guide plate.

Consequence

This could cause the parking lock system not to engage Park when the shifter is placed in the ‘P’ position. If the vehicle is parked on an incline, it could roll away and cause serious damage or injuries.

Recall ID – NHTSA: 04V409000 – 2004 X5

Summary

X5’s equipped with the 3.0L 6-cyl and a manual transmission, if the truck is slowly moving forward in first gear, with the throttle held in a constant position of low engine speed and the clutch partially released, the engine speed may suddenly increase.

Consequence

This condition could cause the X5 to accelerate unexpectedly, which could result in a crash and/or injury.

Remedy

This recall was issued back in 2004, and dealers were instructed to reprogram the Engine Management Control Unit. Owners can contact BMW at 1-800-831-1117. Or the National Highway Traffic Safety Administration at 1-888-327-4236 (refer to recall 04V409000).

BMW X5 Technical Service Bulletins (TSB)

2002-2009 X5 – TSB B24 02 10

Problem:

On X5 models equipped with the GM6 6-speed automatic transmission, the vehicle may not be able to engage a forward or reverse gear.

Solution:

This problem is likely due to a failed gear selector valve, if it has a serial number less than 593323

2004-2006 X5 – TSB B24 01 08

Problem:

On X5 models equipped with the ZF 6HP transmission, the transmission warning light will be illuminated as the transmission enters failsafe mode. Fault code 4F81 (Ratio monitoring, clutch A), in some cases combined with the subsequent faults 507B/507C (Parking gear sensor implausible signal) or 507D (Parking gear incorrectly disengaged), are stored in the EGS control module.

Solution:

Possible causes: a. Low transmission fluid level; or b. Internal transmission pressure leak caused by a defective adapter seal (rectangular) between the transmission housing and the Mechatronic.

X5 equipped with the GM6 transmission – TSB SI B24 04 11

Problem:

On BMW X5’s equipped with the 6-speed automatic, it’s not uncommon to hear a frequent whistling and/or buzzing-type noise coming from the transmission. This noise occurs as soon as the EGS (TEHCM) “wakes up” when the vehicle is unlocked. This noise is heard regardless of whether the engine is running or not. 2. A clicking noise is heard with the engine running and the either the “P” or “N” position is selected.

Solution:

This noise indicates a normal situation which occurs as soon as the EGS (TECHM) “wakes up”; for example, when the vehicle is unlocked. This noise is heard regardless of whether the engine is running or not. 2. To prevent the solenoid valves in the TECHM from jamming or air collecting in the oil passages, the valves are cycled in a frequent manner. This controlling behavior can be heard in some situations. Neither of these noises indicate evidence of a fault, nor are they a result of faulty transmission behavior. Additionally, there is no negative effect on transmission operation or service life.

How to Diagnose & Fix

  1. Check the OBD Codes
  2. Check the fluid level
  3. Test transmission pressure
  4. Drop the transmission pan
  5. Repair, replace or rebuild
