Scania Service Light?????

Hi Guys

I was driving a scania p230 06reg today and while driving a light came on. Its like a pickaxe and keeps flashing for a minute, then goes off and comes back on again. Is this just a service light or what do you guys think it might be??

Many thanks

Time to fit snowchains symbol.

Not the dif lock symbol is it?

Is it the over speed symbol, ‘T’. on my MAN, it comes on for a few seconds then goes off then comes on again until you acknowledge it by ok’ing the Tacho.
