FOR All SAGA FLX, not sure this problem is include blm or just saga flx.
There is a big issue for saga flx, the engine and electric board may directly contact with rainwater.
the rainwater will flow to the engine through the gap between two iron plates which near to the wiper or below wiper.
To check it,
Open the front hood, then slowly pour some water to the car's front windscreen, you can clearly see the water leak out from the bottom middle position of the wiper to the engine and ECU board. this directly
cause the engine JERKING happened in every SAGA FLX.I tested just now, beginning when i pour the water, there is no water leak at the bottom of the wiper to the engine. all the water flow to both corner side(this is normal, all car is like that) but when i pour more abit water, the water starting leak out from the gap between two iron plates the bottom middle position of the wiper (has a screw-nut at there to screw between that to iron plates) . the water directly hit to the engine.
hope all saga flx owner share this to your frineds。
other forum user say that the hole is only can see when take out the wiper and case. i think is screw nut hole.
the only way to solve it cover it by using gun glue(or something like a black in colour glue that use to glue the front windscreen)
