E61 clock/trip reset

Recommended Posts

Hey everyone, new to the forum read a lot but first time posting. I have a problem which as far as my searching skills go hasn't been answered before, I'll start with a bit of history and see what you guys think. OK so here goes...

 

Mid last year the head gasket went on my 530d which killed the engine, and although probably not worth the cost I couldn't afford a new car so got a new engine fitted by a reputable garage. This is where my woes started (at least the unexpected ones)

First thing as I picked it up I noticed increased battery discharge warning, along with adaptive headlights not working and oil level sensor fault. I was picking up after hours so the office was closed but I phoned first thing in the morning and was told the battery discharge would go away after being driven a bit an the headlight was a separate issue due to water getting into the unit and damaging it. The oil sensor wasn't really talked about but I took it back to get it looked at. Over the next couple of weeks I took it back maybe 3 or 4 times but they still couldn't figure out what was wrong with it, so I eventually just coded out the adaptive lights and put up with the rest.

 

So that's how it came about, now the actual issue I'm hoping you guys can help me with. 

Every time I turn ignition on after the car has gone to sleep the dash flashes briefly and all the clocks and trips reset, followed by the high battery discharge warning. It only does it after the car has been idle for 10 mins or so. Also maybe related maybe not the tailgate loses power after being idle for the same amount of time, cant open it or if its open it wont close. 

 

I plugged it in today after finally getting round to looking at it properly (full time 'mum' since being furloughed and the Mrs working full time!) and these are the codes I get. I find it hard to believe all this stuff has failed but here we go

 

93AB Airbag

 

4B37 Oil Condition Sensor

42DE Glow Control Unit

42CE Communication with Alternator

426E Communication with IBS

42AE Communication with Oil Condition Sensor

483D Throttle Actuator

 

6E63 Brake Air Flap Left Faulty

6E0F Instrument Cluster, Interface

5F1A Performance Reduction

 

A559 Instrument Cluster, Power Supply Switched Off

 

E18F Central Registry does not match the target configuration

 

9C55 Fogging Sensor

E714 Message (Battery Voltage)

9C6B Pressure Sensor, Supply

 

Things I have tried to resolve the various issues, with no effect.

New battery, unplugged IBS, had the car on a battery maintainer for a week, new alternator bushes, checked all fuses including ECU fuses, removed map, removed dension kit

 

Any help appreciated, I'm out of ideas that aren't expensive!

 

Thanks!

Is the battery you replaced the same size & type as the old one? if not it needs coding to the car.

 

For the oils sensor it needs replacing; a PITA job as you have to remove the retaining plate under the engine subframe. But it doesn't take that long to do - i'd recommend getting some of the special clips for the bolts as they tend to break when removing this.

Thanks for the reply!  Yes the battery is the same though I know it needs coding that's I assume what the 'E18F Central Registry does not match the target configuration' code is all about. All the other codes were there before the battery change I was hoping it was down to a dying battery like so many other threads I've seen, but that doesn't appear to be the case :(

 

For the oil sensor I have a new one here I've been planning on replacing for the last 6 months or so, but I still think its a bit fishy that all these things came up at the same time so not fully convinced its faulty. I admit I probably should of gotten around to it by now though

Hi and welcome to the forum :cool:.

 

Not experienced this myself but I have previously run across info on one candidate (of many) that can be related to the Central electronic module (Control Body module, E6xKBM module for power distribution management) behind the fuse box in the glove box area (depending on age of manufacture). Might be worth researching and verifying as a possibility.

Thanks for this, I actually found out about this module today via a youtube video, I think I may give this one a go and see what happens. I don't suppose you know what goes wrong with them? A second hand one can be got off eBay for around a tenner but I don't want to buy another dud

Well, unfortunately that didn't work :( I had high hopes this time but I'm still stuck with this issue. Anyone have any  other ideas I could try?
