4 bulb errors but no faulty bulbs?

Post by 0l0dom0l0 » Mon Feb 12, 2018 5:59 pm

Got in the car after it's been sat for a couple of days today and was greeted with an Xmas tree dash showing 4 bulb warning errors as seen in the photo.

Checked and all bulbs are fine and working.

The indicators are flashing fast as if there is a fault. (But all are working)

I have scanned for faults with Carly to no avail, other than the 4 fault codes for the faulty bulbs and 2 codes for driver and passenger hall sensor which I can never seem to clear.

Have loaded a backup onto the FRM from a few weeks ago using Carly. Nothing has changed since then and nothing was changed back then either. No change in warning lights.

FRM can be read and coded with no issue.

Will be checking the PDC for water later.

Anyone got any ideas?Image

Might be worth taking the FRM out and checking the connectors for corrosion. Three of those relate to pins on connector X14261, and are physically close together (pins 45, 50, and 51). Especially on an 11 year old car, unless its been stored in Jay Leno's garage.
E87 118d, stock, plus PDC control unit drain, Parrot, debadged, Mothercare baby shades (but no babies), and occassionally a good layer of wax. Instantly forgettable, and thats the way I like it.

Ok thanks.

Will have to have a look another eve, too cold tonight.

FRM is in drivers footwell, that correct?

Did manage to get out and disconnect the battery for a few mins but 're connected and faults still appearing.

Is it likely to be anything to do with PDC? PDC works no issues.

I am suspecting an FRM issue. Thought it might be bricked but doesn't seem to be.

Will check that too.

Been reading into FRM failures. They are sounding similar to my symptoms.

I'm wondering if not coding my heated seats yet might have bit me in the ass so the first thing I'm going to do is code them and do a code to default on the FRM after I've added the heated seat option to the VO and see where we are then.
