Maybe while soldering you put too much solder on that something was bridged?

I have yesterday changed on a cluster with grey backplate the capacitors.

There are 2 47mF 40 Volt and 3 220mF 16 Volt.
I have replaced them ALL with 35 Volt ones.
You just have to pay attention to the diameter, otherwise they do not fit, max. thickness/diameter of 10 mm is possible and NOT high than 16 mm.

The distance between the "feet/legs" of the capacitor should be 5 mm.

The ones I yesterday changed were 22mF, replaced now by 47mF,
the bigger the better.
In some clusters there are instead 47mF also 22mF installed, open your cluster then you see what is inside. Better are capacitors which can stand a temperature of 105° Celsius. Because in summer time the inside temperatures are hot (when car parked) and also the chips produce heat. That is accdg to my opinion the reasons why the capacitors dry up.
