Good morning I bought an old sprinter from Bj 2001 as it turned out the dig start problems. The car ran 170 thousand. What I have changed so far was the battery with 95 Ah(the starter turns but it starts after 10 to 20 try and with a 110ah battery immediately), the fuel filter with the black return valve and the green seals were there in the fuel system air bubbles. And now I don’t know any more. What I have tried with startpilot doesn’t want to roll down the mountain in the 2nd gear clutch, he doesn’t want to let go. But when the engine is running it doesn’t cause any problems he doesn’t pulls it off on his own. Regardless of whether it’s cold or warm.
