Hello, the 10 year old Mikra (K11) 1.3 / 75 HP my wife has after just these 10 years his first Macke. mileage 50000 km. When buying directly at Nissan an immobilizer was retrofitted, otherwise the car is standard….. From now on he started to jerk and run out during the ride. In a start attempt he does not jump, although the starter has turned, on. After about 10 minutes he jumps again and drives also. We tried about 8 km – no Problems – also performance is there. Then the whole thing played out a bit differently during another test drive: It runs about 6 km perfectly and is then parked. after about 20 minutes break he starts after several attempts and then runs only 20m! After a few minutes he wants to go again, during the 6km return trip he stops again twice. Can anyone give a tip? Greetings from the Ruhr area Klaus
