Hello, at that time I installed a battery that is probably too small in the L300. Now this is completely destroyed. I then added a new battery with 70AH. It fits in like this (with a lot of tricks). Now I get my L300 again wonderfully let off but the control unit for example lets the speed when braking and clutch stepping into the cellar rush. Partially then even the battery charge control light or the car goes out. aar seconds and finds the correct idle speed. At the next traffic light stop it is the same again. Several times I tried the procedure. 10 minutes run without a consumer, then 90 seconds run out and then with all consumers 10 minutes run. Had also worked well one or three years ago. Only now he somehow doesn’t want to. Also again disconnecting the battery brought nothing. The friendly only meant that he then had to expand the seats elaborately to the Only then would he have the possibility to manually raise the stationary gas. But that costs and is somehow unsatisfactory. The L300 finds its speed, only a few seconds too late. So it can only be due to the control unit, right? What do you do? Just continue driving – maybe it will work on its own at some point? Does anyone have a tip that can be done by themselves? H E L P – please.
