L322 YET ANOTHER LCM ISSUE

[Pug957]

Hi Guys

2006 L322 Vogue TD6

Got an odd one here. I have tried searching but only seem to find a thread about coffee and walnut cake and lemon drizzle from a few years back.

Got 20 fault codes permanently stored in the LCM which I cannot clear off.

The odd bit is everything seems to work fine.

I walk around the car and all the lights, rheostat etc all work fine. The only "issue" is main beam bulbs and licence plate bulbs are LED and flicker with the bulb check. They don't put messages on the dash unless one is actually out though.
The screenwash and coolant messages only come on if the levels are low. Brake warnings only come on when the sensor wires break as they're meant to. The dash dims and brightens with the thumb wheel. All fuses throughout the car are fine.

Just in case it was the LEDs, I fitted brand new standard bulbs all round, but the codes persisted.

These are the codes:

0x000D Redundant inputs contradiction fault
0X0010 ECU transistor (line 3) fault
0x0017 Dimmer potentiometer circuit open
0x003C Please refer to service manual
0x0059 Transmission emergency program fault
0x005A Brake pad fault
0x005B Washer fluid level fault
0x005F Check the coolant fault
0x007A Left front side Lamp faulty
0x007B Right front side lamp faulty
0x007C Front right turn signal faulty
0x0080 Left High Beam Headlamp
0x0081 Right High Beam Headlamp
0x008C Left tail lamp faulty
0x008D Right tail lamp faulty
0x0090 Left rear turn signal faulty
0x0093 Left rear fog lamp faulty
0x0096 Interior security rear - fuse or cable
0x0098 Please refer to vehicle service manual
0x0099 Licence Plate Lamps faulty

Not sure if the LCM stores backup data within it and the first 2 lines are the real issue here. Maybe the transistor is blown causing it to lose access to the backup data or something soft like that?

Anyone any idea what the issue may be?

Is it the original LCM? maybe someone replaced it with the wrong model year. Later LED version etc.
Is the tamper dot displayed on the cluster?

 

[Pug957]

Not sure about previous owners replacing it but there's no tamper dot on the display. The fact the lights flicker with the bulb test suggests it's intended for normal incandescent bulbs so I'm thinking it is original.

 

[backinblack]

The bulb test can be turned off/on but I suspect you are right. Think my Foxwell gives date of manufacture but no idea about you're diags

 

[Pug957]

It's YWC500281 HW:07/SW:2.1 which looking at google results suggests it's about right.
The VIN coded in is correct as well.

Reading round a few BMW sites suggests it backs up the configuration file and uses this if the primary file fails. Wondering if the eeprom that stores said info is duff and it can't read the backup so is just having a sissy fit.

Just got a GAP IID through the post today so will see if that can shed a bit more light.

Walnut cake, sounds like an admin.

Walnut cake, sounds like an admin.

It was a discussion about acceptable forms of payment

 

[Pug957]

Looking like IID Tool was able to clear the faults. Will keep an eye for the moment but it's achieved more than a few code readers have managed to do. Also turned off cold monitoring of the bulbs (hopefully) so will see what happens there.

Although not got the option to flash the lcm firmware to get 3 flash indicators working though. Will have to do it the old fashioned way and actually drive the car

Probably my old tread, lemon drizzle is my specialty

I heard Walnut cake mentioned were is this said cake as iam hungry now
always room for cake

This was the thread. Always popped up even in Google searches trying to figure out my problem

L322 - 2005 TD6 LCM Coding

Need some help with LCM coding please. I have replaced the faulty LCM with one from a 2002 V8. The replacement LCM worked fine but kept saying check dipped beam so I got it recoded by someone local (free of charge) and now the side lights won't work and it keeps saying check brake lights. I...

Yep my old thread. learned a lot about cake in that one, and a bit about LCMs

 

[backinblack]

And now another LCM question that includes cake

 

[RangeRoller dt]

Hel probably get the lcm sorted, for now, atleast he has learned how to derail a thread with cake

 

[Pug957]

Some things in life are more important than LCM modules

We usually get the answer to the problem then go off on a tangent. You get a head start coz we like you

 

[Pug957]

Well at the moment it may just be a diagnostic tool not being capable of deleting codes. Will hopefully find out shortly if it worked or not.
