obc Warnings ??????
I have a 91 525 (recently purchased) Starting to flash warnings on dash eg. low coolant level, brake light circuit, and suspension leveling. I have had all the bulbs checked (brake light circuit) and not one of them was bad?? The coolant level is right where it should be and Im not sure yet on the suspension leveling warning, but I wonder if there is something Im not checking on these things (brake lights/coolant level) or could I be having problems with the obc or ??? Any ideas would be greatly appreciated.

Re: obc Warnings ??????
1] 'brake light circuit': replace the switch
2] 'coolant level': replace the level switch in the bottom of the reservior 3] 'suspension leveling': ? ? ?I've never seen a 525i with self-leveling ? ? |

Re: obc Warnings ??????
Tina, sorry for the delay in getting back to you, yes, I mean, NO, I've never seen an E34 with 'self-leveling EXCEPT for M5's though all of them are 'wired' for the sensor. I can't recall seeing the warning on a 525i BUT you state the rear 'squats' quite a bit. Though not a common problem, it sounds as if you need rear springs. A previous owner may have been carrying pick-up truck loads in the trunk. YES, a pic of a side view [with the trunk empty] might help but I'm fairly sure your problem in the rear is the springs. Await your reply..................jeff b.

Re: obc Warnings ??????
I'm sure it's me, but your car looks slightly high in the front as opposed to being to low in the rear...??..Let's try this, an actual measurement I can use to compare yours to factory spec's. This measurement is call "ride height". It has NOTHING to do with how far your car is from the ground! It's a CHASSIS measurement so try to do this exactly as I tell you, not what might make 'common sense' to someone else.
All you need tape measure, metric would be great if you have one, I'll do the fractional conversions otherwise. [ a drawing would be so helpful here ] At each wheel, measure from the lower lip of the rim [closest to the ground] up through the wheel center cap, straight up to the lower edge of the body wheel opening. This will be perpendicular to the ground and ,again, from the bottom of the WHEEL to the bottom edge of the wheel opening on the BODY. Record all four corners, post them and let's 'see' what we have................best to you.................jeff b. |

Re: obc Warnings ??????
Tina, I'm back, sorry once again for the delay.....while I 've never seen a car measure so evenly side to side your front /rear readings show something interesting. Loaded vehicle height [ 'normal load = about 300 lbs. in the front seats ] is 20.551" with 15" wheels and while this kind of diagnosis from 500 miles away and on line is boardering on the extreme, it does appear the front is quite high, even in your somewhat shadowed pictures. Note that your measured ride height spec on any BMW is always the same front and rear with-in a spec tolerance. Your situation seems a bit unique, how often do you drive up to Seattle?
As far as your WARNING diplay goes, while I've neglected to inspect another E34 for the presence of the rear wheel sensor, ALL E34 clusters have the ability to display the information but 525i & 535i's wire this cluster pin to a constant low signal making it non-functional while M5's & 525ti's ARE wired to this sensor. I do want to be of help with your problem, what can I do to assist you further [ I'm still investigating the WARNING ].................jeff b.......... |

Re: obc Warnings ??????
Well the measurements may have been off a little, like less then a 16th of an inch but I don't think anymore then that. I will have someone else do the measurements tomorrow and post them if you like??? As far as getting up to Seattle... Not very often. Im not sure what else you can do??? Should I be concerned with this?? (ride height issue) Should I take it to someone to have it checked out?? Thank you for all your help and I will wait for your reply on the warning light??
