Hy As described above, the car is running out of traffic lights. It runs uneasy in the stationary gas and the DZM is shaking, so the speed changes can be seen, that makes it a few times and then goes out. Citroen meant that it is located at the blue point radio, which disturbs the motor electronics. However, it was connected with the original adapter of Citroen. I now made it as recommended, directly to the strippings at the ignition lock (with fuses). As long as the radio is not on. The radio is not turned on since yesterday. So it is still in the test phase. Date at the dealer is Monday, but wanted to check as much as possible. Oh yes, the lamp flashes/lights from time to time from the motor electronics and then goes out again. In the error memory there is nothing in it. Air filter is still ok, spark plugs I check afterwards when the engine is cold again. What are the costs and which really are the costs? Do they have a change interval?? The book says what of 60tkm, but the car is used almost only in urban traffic. MFG Sebastian
