BMW How To, E39 5-Series 525i, 528i, 530i, 540i, M5, Strut Spring Seat and Spring Alignment

Jul 26 17

One of the common requests for tech assistance that we receive, here at BAVauto, involves the proper alignment of the front shock/strut spring seat and the spring on the BMW models that have the elliptical, or “egg”, shaped lower spring seats.  This includes the E46 (3-series 99-05), E39 (5-series 97-03), E60/61 (5-series 04-10), E63/64 (6-series 04-10), E85/86 (Z4 coupe & roadster through 08).

Typical Elliptical Spring Seat:

At first glance, an installer may assume that the spring installs on the seat with the end of the spring butted against what appears to be the spring stop on the spring pad, as many (if not all) older models would have been designed in this manner.  This install position is, however, incorrect and will result in a misalignment that will cause the spring to dislodge from the spring seat..  See the images below, which detail the proper spring and seat alignment.

These photos are from a customer who was having noise and steering issues after the installation of new shocks (struts) on his E39 540i.  While the photos are not the best, you can see how the spring is falling off the spring seat and the end of the spring is improperly positioned:

BMW and MINI How To, Coolant Hose Quick Disconnect Clip

Jul 26 17

Dear Otto,

While I was replacing my radiator, I pulled one of the coolant hose quick disconnect clips off the end of the hose.  Now I can’t seem to get the hose to stay clipped onto the radiator nipple.  It’s a newer hose, as I replaced all the hoses just a couple months ago, so I don’t think the problem is that the hose end is won out.  Actually, I’m not sure that I have the clip reinstalled on the hose correctly anyway.  Can you help me with this? Thanks, Aldo

Aldo,

If the hose end will not stay connected to the radiator nipple, it’s likely that you are not getting it fully pushed on to the nipple, the clip is not being fully pressed into the locked position or the clip is not installed correctly.  This is assuming that the nipple is not damaged or broken and that the hose end is also not compromised.

When installing the newer quick-disconnect coolant hoses, they can often be difficult to push fully on to the male nipple.  Lubricating the o-ring that is captive in the female hose end and the barbed male connector end with coolant, silicone grease or petroleum jelly will greatly ease the installation of the female connector end over the male nipple.  Be sure that the locking clip is pulled away from the hose end, in the released position before attempting to connect the hose end to the male nipple.  Once fully pressed on, the securing clip should easily press in to the locked position.  See the photos below.

* After looking at the photos, Aldo wrote back to say that he was able to determine he had installed the locking clip incorrectly onto the hose end.  He fixed this and now the hose stays connected as it should.

BMW Recall – Door Latch (UPDATE) – 745i, 745Li, 750i, 750Li, 760i, 760Li – E65 E66 – 17V328000

May 31 17

BMW is updating the recall on various E65 and E66 chassis 7-Series models, to include; 745i, 745Li, 750i, 750Li, 760i, 760Li for models years 2005 through 2008 with the Comfort Access and Soft Close options, to include more vehicles than the original 2012 recall # 12V504.  Affected model years are from 2005 through 2008.  A potential problem in the software for these automatic door closing functions may cause the doors to appear to be properly closed, when in fact they may not be, and can open.  The repair is to update the applicable software for these systems.

According to the recall:

“The door may unexpectedly open due to road or driving conditions or occupant contact with the door. The sudden opening may result in occupant ejection or increase the risk of injury in the event of a crash.”

The recall  does not yet have a scheduled begin date.  Owners of affected vehicles are being notified by BMW.  Further information can be obtained by contacting BMW customer relations at 1-800-525-7417.
