I've had one of these electronic dipsticks on my bike since my '08 was new. When I traded, I kept the electronic dipstick and moved it to my 2010. Over the years I've heard people complain about these things a lot. Seems in a lot of cases, they last a year or 2 and then become unusable, for whatever reason. Well, mine finally became unusable. Over time, the display was obscured more and more, finally getting to the point it was unreadable. When I did my 15k oil change yesterday, I opted to put the stock dipstick back in.
Well, as some of you know, I'm Jewish. In keeping with that particular stereotype, I'm somewhat hesitant to toss something I paid $150 for, even if it was several years ago. Yesterday, when I finished with the bike, I started to take the dipstick apart. Easy enough to get it partially apart, as you need to do that anyway, to face the thing properly when it's installed. Problem was, the circuit board uses VERY small torx screws to hold it together. Today I stopped by Sears and got a small torx screwdriver set, not being sure of the size (smallest I had was a T-10). Found the right size, took it apart, cleaned out all the oil buildup, put it back together.....works fine now. Screwdrivers cost me $10, a new dipstick (if I got one) would have been $150 (less any discounts). Took me maybe 15 minutes, once I had the right tools.
Moral of the story, don't throw them out if it happens to you...just clean it up.
