had a constant tiny oil leak after replaceing my speedo sensor...

was extra annoying as the oil collected on the undertray, and when i parked on my slanted drive it would all pour out.

had a read up on here and tried siliconeing it in.

still leaking.....was half thinking it was the diff/gearbox seal on that side.


turns out the bas**rd sensor was leaking through its top cap....one of its plastic clips was duff and not latching the lid on.

i had a diff sensor that was sealed/potted on hand...aliexpress of all places...

no more leak Big grin
