Hello everyone, my Clio has been bothering me with sporadic ignition oscillations as soon as it is warm for quite some time now. I have recently had the problems also when turning up in idle and accelerating. The control unit recently reports DF110 (destructive misignition) as well as misignition on cylinders 1 and 3. The following possible sources of error have already been tested: – spark plugs: all only 15Tkm in and optically, exchange between the cylinders does not allow the error to move – ignition cable: au ch only 15Tkm in it, no nibble or scrubbing tracks – two-circuit ignition coil: Exchanged for original new part of Renault (old had cracks in plastic), no improvement – compression: All cylinders between 12 and 13 bar – injection valves: runtime/age unknown, replacement of injection valves does not make the error move I pull cylinder 2 off the ignition coil the engine hardly runs any more, with cylinder 3 the least deterioration in the round run. Since the two-circuit ignition coil always zw a cylinder fired at the same time (1 and 4 as well as 2 and 3) I have put cylinder 3 at coil output 2. Now the engine with cylinder 1-3-4 runs just as well as before with 1-2-4. If I hadn’t already changed the ignition coil for a new one, I would have been the first suspect. What is left of error causes? -OT-Geber? -Control unit? I would be grateful for suggestions or corrections of my previous analysis. MfG Robert
