Hi all,

I’ve got an intermittent electrical issue that I’m trying to get to the bottom of.

It only happens as I initially pull away — either in drive or reverse. As I press the accelerator to move off, I get a brief flicker where:

• The dash/clocks dim momentarily
• The green headlight indicator comes on (and possibly the headlights themselves, although I haven’t fully confirmed that yet)
• The interior light flickers on

It’s just a split-second event, then everything goes back to normal.

A few key points:

• It can happen from cold or when fully warmed up
• Only occurs at the moment of initial movement
• Never happens while driving, revving, braking, or cruising
• It’s intermittent — sometimes it won’t happen at all during a drive, other times it may happen more frequently

What I’ve checked so far:

• Battery tested — healthy and around 18 months old
• Battery terminals removed, cleaned, and refitted
• Battery-to-chassis earth removed and cleaned (looked clean anyway)

I’ve had a suggestion it could be the body control module, but I’m not sure how to confirm that or whether it’s a common failure.

Has anyone experienced this exact issue, or got any ideas what might cause it?

Thanks in advance 👍
