The temp stays the same...you're not looking at the needle are you? It's lying to you... Could be anywhere between 80 and 100c and sit at 90 lol...
When the fans are on it 'may' be doing a regen then, you wouldn't necessarily know tbh. I can usually tell by a change of engine note (sounds rougher) and the MPG dropping when it should be steady. Sometimes can smell it also, hot cat stinks, and smells of hot soot as well. Others reckon they see smoke but I've got factory tints so cant see anything lol. And of course the fans running on after switch off are the biggest telltale of a regen being stopped midway.
