Last few weeks the Stack temp display has been all over the place when the engine warms up, 78, 56 ,92, etc.
Wasn’t too worried as there weren’t any other indications of it being ‘you know what’ 
- replaced the blue temp sender and its now returned to a rock steady 80 degrees 
Yeah those blue temp senders are known for being a bit dodgy!!
I was stuck on the Dutch German border this weekend in a sh1tty traffic jam. The stack was fluctuating all over the place after it got over 109deg It was giving 999 to 138 and all over the place while we got moving again and it settled down.
Seems ok now???

Well worth checking that the fans work. In fact, I’d strongly recommend fitting a manual switch too
Indeedy I’ll check the fuse too.
Dave at emerald upped the fan start temp but I have to admit its the first time I have seen it so high
