Dear community. Since my mechanic is in the dark, I put my problem into the forum. Car: Renault Grande Scenic 3, 1.4 Tce, 132 tkm, Bj 2009 About 8 weeks ago the “elderly” started. After the start the engine control light lit up longer than usual. The engine no longer took on gas. (Gaspedal pressed through, nothing happened) This only for a short time, then he drove, light went out. The free workshop first changed all 4 spark plugs. Two weeks later (the said problem tr In the second attempt, it works. Read out in the workshop. Misigned ignition at ignition coil 3+4. So all candles changed again and the two ignition coils joined. 2 days later, the problem reappears (light light lights up longer, short jerking, but then picks up gas). Go into the workshop and read out. Again, something with ignition coil. Mechanic suspects that what is on the steering chain (a rattle I hear a rattle) It’s not really necessary to change the chain. To see what is, you have to disassemble almost the whole engine. The mechanic advises me to buy another car. He thinks the problems (after the control chain) would accumulate with this model with this engine. A groschengrab so to speak. My question: Is the problem really the control chain? And if so, is it worth a repair or is the mechanic right with the drive? Thank you for your help. e lg Sepp
