SELFLEVEL SUSP.INACT
 

Help... Dash board going off like Fourth of July...LOL My SELFLEVEL SUSP.INACT Light has come on along with the ABS and other lights associated with the brakes. Also When I start to go in the morning the Fail Safe trans light goes on when the car gets warm. That's not all. The speedometer is also not working. Reading the forum around the web led me to believe it was a ABS sensor. Replaced the left rear. The fail safe did not apear for 1 whole day but all the rest remained. When Fail safe trans. light goes on I do feel the low power at start. The susp. level seems to be pumping up with a trailer attached but sometimes in the am it is all the way down until i get in the car them it pumps up. Crazy things going on. It all started when I went to the lake with my jet ski and backed the trailer into the water to unload. As I left the lake that day the lights appeared. I am thinking I may have backed in to the water deep enough to get to the level of the ABS sensor. Any thoughts????

First you have to check with codes scanner to know which sensor is defected
but for sure you have ABS sensor issue ..maybe wire disconnected maybe the sensor itself maybe abs module!
moreover check the level sensor and rear air spring status.

Maybe just the battery .. have you checked the level using the OBC?

you say it has happened after you backed up the car into water. even if the wheels did not go deep enought to catch the sensors, you still may have caught the trailer socket.
you should be looking for the culprit in the back of the car, you say you replaced ABS sensor in the left rear - you might have to check the right rear as well... that also may apply to the level sensors, that are on the rear axle...

also, check the battery compartment, there might be water in the battery tub...


it would help a bit, if you would include your car's model and the month/year of manufacturing, along with the mileage

Thanks for the reply. I have an appointment on Wed to have the codes read. I will post an update then.

The battery is newer about 3 months old. How do you check the level using the OBC. I will check the manual for info. Any links that you may direct me to would be great.

Thanks for the reply.
I have a 2000 X5 4.4 manufacture date 3/2000 miles 139,000.
I checked the battery compartment and no water. Dry as can be. Also after I replaced the left abs sensor I disconnected the battery for about ten minutes to see if that would clear any codes with no change to the dash lights.
Having codes read in the next couple of days. I will post an update then.

2000 x5 Selflevel Susp.inact
 

I have returned from an independent BMW repair shop. They have read the codes and said I need a new ABS module. I have attached a copy of the print out from the shop. The price for them to replace $1150. installed and reprogrammed to my vehicle. They did not give me an option to rebuild.
So I have went on the forum and have removed my module and have it ready to ship to have Rebuilt. So far I have two options:
Module masters wants $300. and will give it a five year warranty if it can be rebuilt.
ASI(Automotive Scientific Inc.) Says $150. and a lifetime warranty. I do not think I will own this 2000 for very much longer so just wanting to deal with the best company to do the job right. Anyone had any experience with ASI or ModuleMasters.
ASI say their turnaround is 5 business days.
Please advise on any concerns I should consider. Thanks in advance for any and all replies. Cheers

I've heard cheapabs does a great job (Don't let the name fool you)

www.cheapabs.com $139 warrantied for life

BBA (the best option as rated on Bimmerfest) is running a sale on their eBay auction: $96.42 shipped. You can't beat that.
I had my ABS rebuilt for my E39 by BBA, lifetime warranty.

vehicle speed, signal - what did they say about that code?

they based their assessment of dead ABS module on the fact that it timed out, so, there was no connection... a very likely culprit...

but your EGS times out too... as well as DME... but we know, that they do work, your engine is running, and the transmission still proppels the car forward...

Still been meaning to send mine in to them. Glad to know the sale is on again for the next month as the alignment/tie rod issues killed me lately.
