Since my last post the lack of power has happened twice.
The error codes read 1/12/13 are:
EWS
0f (015) Power on reset

SRS
50 (080) Power Supply, undervoltage (supplemental Restraint System)

IKE
BD (189) Electronic braking – force distribution

LCM
5B (091) Level washer fluid
62 (098) MRS sent occupancy recognition fault
92 (146) Left brake light
94 (148) Rear left fog light
95 (149) Rear right fog light
96 (150) Left reversing light
97 (151) Right reversing light
99 (153) Licence plate light

NAV
05 (005) Temperature high
4 errors – description unavailable

All error codes reset except the one above in red, so i did another scan...
After rescan:
SRS
50 (080) Power Supply, undervoltage (supplemental Restraint System)

ZKE
95 (149) Interior security, fuse or cable
8A (138) DWA-Alarm : tilt alarm sensor
80 (128) DWA-Alarm : Terminal R

All reset except the same error code:
SRS
50 (080) Power Supply, undervoltage (supplemental Restraint System)

Does anybody recognise an error code that maybe linked to the drop in power?
Also does anybody know what the SRS error code is referring to?
Thanks.
