thats a strange incredible problem on my mondial 88 3.2 i insert the key and when i turn the key on , (position two,before the turn on engine) the upper odomoter start to count!! 1,2,3,meter 10,20, and increase the general mileage and its sooo fast!! yesterday i try to check the fuse box, the car jump 1000 km just parked!!! thats insane!! when i turn on on position 3 and start the engine, everthings work, but the partial odometer count fast too!!! car are very pristine 49800 original km, two owners, (me included) keep in the garage and serviced for all his life! i suspect two problems 1) electrical problem inside dashboard instruments (hell to disassembling) 2) speedometer sensor on transaxle send crazy signals (but rpm and speed working while odometer running like slotmachine) somebody can help me ?
