Moin Moin! As a winter car I bought a 850er (140hp) Limo BJ 94 / petrol / manual circuit. The vehicle is very well maintained and currently 182,000 ran. Now I noticed the following. If I press the brake in the stand, the motor – speed remains the same. Pump me a few with the brake pedal, normalizes the jerking and the engine runs completely calm. Same happens when you brake when you drive – the engine jerks. Pump me while driving/braking also like r easy, everything normalizes again. I already made an appointment in the workshop for next week, for a complete inspection. But maybe someone has an idea what that could be – or maybe I could fix it myself in advance. Thank you
