Well, as of this weekend it looks like I have a little reading and some tinkering to do.
I went to fill up with gas and it took forever to fill up. It kept shutting the pump off like it was full. Took me a long time to get it full. Then after driving for a while the gauge never went it, it's all of a sudden always reading full.
I drove another 100 kms and the needle still said full but I eventually got it to take another 10L of gas. This time at another station and the pump kept clicking off again. Super annoying...
Not sure if the two are related yet but they both started happening at more or less the same time.
