I've booked my car at my regular garage to be checked out tomorrow. There's a problem with my main dashboard computer in my old 307 HDi.
Last night, these warning lights, including ESP, came on and stayed on, with the stop light flashing.

I continued my journey, got there, turned the engine off, went to do some work, came back to my car half an hour later and all was normal again on the dash and stayed normal as I returned home. It was fine this morning too on my next journey.
On my way home this evening, a few minutes into the journey, the same lights came on again, plus all my mileometer readings had now gone, just dashes, plus the low fuel light was now flashing, even though I have well over a quarter of a tank. Then about 20 or 30 minutes later, the water gauge, rev counter and speedometer stopped working. I had no idea of what speed I was doing anymore, so drove slowly. Left and right indicator arrows were not showing up on the dash either, but I checked outside the car and the indicators were all working.
Got home, turned off the engine and lights. These dashboard lights remained on. Went into my house for a few minutes, came back to the car to drive it to the garage in my street, and the dashboard was again completely back to normal. Even the mileage readings were intact.
I've had intermittent problems like this before. After my alternator was replaced a few months back, the battery warning light was still coming on. But after a few days, it disappeared.
Can I be optimistic and hope it's just a loose connection somewhere? I've got three long journeys tomorrow, saturday and sunday, and have had to make contingency plans in case I don't get my car back for a day or two.
At the moment, it seems to go back to normal after switching off and waiting. I could risk using the car, but I'm just worried that it might go kaput altogether and I'd be left with no speedometer.
