Hello dear forum friends. I have the following problem. Renault Laguna I Grandtour 1.8 16V Bj1999. The vehicle went out abruptly during the ride. The vehicle can no longer be started. On error reading it was shown that all 4 ignition coils are defective. I find it very unpredictably that all ignition coils at the same time give up the mind. I have precautionally changed the OT-ber also this did not bring any success. I fear yes, it is the control unit, but maybe h at yes here someone else an idea what else it could be. ECU would be the death sentence for the car. Just closing the info…. Spark no … sprite yes… timing belts not skipped… I thank you already now.
