Hi! Newbie here, my missus owns a '05 182, car ran like new until a couple of weeks ago, all started with what seemed like a coilpack problem, the car was running fine, then suddenly we got no power and it started to run like on 3 cylinders, maybe only 2 because it was rough as hell, and we had no control over the accelerator, but it did not die any time. Lumped it at about 10mph to a secondary road and stopped, car was idling fine, but when you tried to accelerate, started the rough running again... back to idle, and everything fine. We let the car run for about 5 minutes, and then, the problem disappear as fast as it appears. No more problems that day.
We parked the car at home and let it alone for like 5 days, then, when we tried to fire it up... nothing.
- No MIL light on the dashboard, not even at the ON key position.
- "Stop" engine-like red light: on.
- No starter motor, unless you move the key fast enough in the first 5? (maybe less) seconds, passing from off, to on, to start as fast as you could. Then, after about 2 seconds of cracking, the car itself shuts the starter motor off.
- Plugged the Clip diagnose system from renault, we check out the inmo, everything fine related to it. Every other ecu it's ok BUT the engine ecu. The car can't conect to it.
- Tested another ECU and UCH, same problem. Right here, we know or at least we assume that it's wiring related. The other ECU and UCH came from a runing car, and after we plug in ours, and gave then back to it original car, the car ran fine.
- I've checked every relay, every fuse, and even took the wiring cover off the ECU, and test out every +12 and earths pins. Every +12v has +12, and every earth has earth.
So... i assume... it's the 27 and 57 pins, the two can bus ones. Maybe one of the wires it's sorted anywhere...
Where do i start looking? Any tips? The missus drives me crazy every day after i came back from work, because we live in a remote and it's not a realy good conected place... so she's alone at home everyday until afternoon. Please help me with the poor clio, before she kills me. :lolup:
Ps: Sorry for my bad english, i'm from Spain!
