Scanned the pages already for ’the' good diagram ( there used to be a good one on Wiki, but that seems empty now. )
Problem as follows: Very intermittently, the LED on temp gauge refuses to stop flashing after starting.
The fluid levels are good. If I turn off ignition, sometimes it clears and returns to normal, other times I need to do it a few times.
Other weird ‘happenings’ involve taco needle bouncing erratically when LED flashes problematically, and sometimes the temp needle when driving moves to 3/4 range ( LED never flashes then though. )
I know that’s often considered ’normal range’ but TBH, it isn’t for my van. The needle always sits right on the red LED ( and is always covering some of it at all times when up to temp. ) Weirdly, the next time I drive it, it will sit it its normal position for days at a time - until it doesn’t lol.
It is so intermittent that I am going to struggle fault finding this, so want a bit of a ‘sanity’ check from those with superior experience or knowledge. The plan is as follows;
Remove ‘relay’ 43 from fuse board, and ensuring I keep in mind this will stop low coolant sensor working ( so must keep an eagle eye on it ) I ’think’ I can drive like that for a bit to see if any of the gremlins return.
If they don’t, I can replace that item, if they do return, I need to have a deeper look.
Am I correct here? Viable plan? Being an idiot?

Feel free to point me right if I am wrong. All input appreciated. I appreciate with the temperamental nature will mean this will rn on and on, but it needs sorting.

P.S. I have seen comments where some temp gauges have capacitors that fail. That will be further down the line of things to check once I have eliminated other issues.
