So, today I thought I'd try and fix my dodgy LCD in the instrument cluster. I was following a guide I found on the interwebs but I only got as far as removing the speedo needle before realising I could get to the LCD without removing the dials. Pulling all the needles off is a horrible idea.
Anyway... All put back together, plugged back in, LCD still broken but now, when you turn the ignition on and start the engine the speedo needle jumps around from before 0 to about 5mph for about 5 seconds. Whilst it is doing this, none of the other needles register so tacho, temp, petrol gauges don't work. It then settles and the other gauges kick in. It works as normal after this.
I took the cluster out and cleaned up contacts but this issue is still there. As everything seems to work otherwise, it's not too big a deal but something has obviously changed. It's as if it's calibrating or something?
It does the same thing when you switch the engine off.
Anyone seen this before? Is this normal if you remove the cluster and plug it back in?
