51 37 154 Adjusting rear left or right side window (convertible)

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2013 BMW 328xi, 2013 BMW 328i, 2012 BMW 328xi, 2012 BMW 328i, and 2011 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.

Prerequisite:

Vehicle must be standing on its wheels on a level floor
Door window glass correctly ADJUSTED

Necessary preliminary tasks:

Remove REAR WINDOW CAVITY SEAL
Open retractable hardtop
Move side window upwards (close)

Ideal adjustment, transversal direction:

Side window glass (1) must be situated at distance (A) to body (2).

Distance A = 7±1 mm

Measuring points in B-pillar area and release for rear screw connection of side window glass (1).

Adjusting transversal direction:

Remove side trim upper section.

Slacken screws (3) and adjust distance (A).

Tightening torque: 10 Nm

Ideal adjustment, longitudinal direction:

Side window glass (1) must be positioned at distance (A) to door window glass (2).

Measurement (A) = 12 ± 1 mm

Parallelism deviation ± 1 mm.

Side window glass (1) may have a max. underprotrusion (B) to door window glass (2).

Measurement (B) = 2 mm

Adjusting longitudinal direction:

Slacken screws (1) with special tool 51 3 310 .

Adjust longitudinal direction by moving side window glass (2).

Tightening torque: 10 Nm

Installation:

The specified torque moment 3.5 Nm (MDE) is reduced when using special tool 51 3 310 . Depending on the torque wrench used, this must be calculated in accordance with the adjacent overview:

MDE = Torque to be set

MDV = Prescribed torque (without special tool)

lj = Standard adjustment length with adjusting tool

l1 = Effective length of torque wrench

l2 = Inside dimension of adjusting tool

lw = Inside dimension of insertion tool (here lw = 145 mm)

NOTE: If screwing is performed from the inside of the door (removed door trim panel), the tightening torque to be set (10 Nm without special tool) must be observed.

Checking retraction depth:

Close retractable hardtop
Open door window
Attach special tool 51 3 080 to side window glass
Close side window completely
Measure retraction depth

NOTE: Two 51 3 080 items of special tool are required for adjustment of retraction depths.

Measure retraction depth (A) in areas (1 to 2).

Measurement (A):

(1) = 8 ± 2 mm

(2) = 8 ± 2 mm

If necessary, check or readjust settings on:

Door WINDOW GLASS
Side window

Ideal adjustment, pre-tension:

NOTE: Pretension can be checked with or without window cavity cover strip. Pretension is 1.0 mm greater with window cavity cover strip. Magnet in special tool 51 0 341 (adapter) creates the correct door window glass pre-tension on the seal system for measurement. No force must be exerted on the door or door window glass during measurement.

Insert special tool 51 0 341 (adapter) in rotary striker of door lock and close rotary striker manually. Carefully close door.

Measure gap (A) between side window glass (1) and inside edge of door window glass (2).

NOTE: Measuring point 10 mm below top edge of window glass.

With window cavity cover strip fitted (front and rear): A = 20 +1 mm

Without window cavity cover strip fitted (rear): A = 19 +1 mm

Adjusting pre-tension:

Remove rear window cavity cover strip.

Turn adjusting screw (1) with special tool 51 2 220 (Torx) until correct pretension is reached.

NOTE: With hardtop closed, side window glass (2) must run correctly into hardtop seals (check only when window cavity cover strip fitted).

Checking adjustment:

Open door window and side window.

Close both windows simultaneously and check run-in of side window glass to door window glass.

Close retractable hardtop.

Hardtop seals must not be damaged.

Check run-in of both windows in hardtop seals.
