Hi Martin There's probably nothing wrong with your German language skills, as the wiring diagrams aren't included in the "Electrics" manuals. I'm sitting here with the diagram for your car... and I'm think whether it would be of any use to you? There's a lot of electronics in there and it could be lots of things that are wrong. The engine management computer seems to have more than 70 wires going in and out of it, and there's also several additional heaters too. I think the best would be to run a diagnostic scan on the engine computer, hoping that it "knows" what's wrong already. I can make a scan of the diagram if you absolutely need it, and then you could work your way through each and every wire to check it. But as we don't have any means of checking the sensors, the chance of succes in identifying the problem is probably quite small. I'm afraid that wasn't much help... - Anders

It is *possible* that both have failed, but I think it's more likely that it's the computer that is confused. The thing is that if one of them is failing, the computer can't know which one it really is. It would have needed a third sensor to know for sure. Of course it has certain criteria that must be met before it claims a sensor to be faulty, and I would expect that "weak signals" or something similar would be one criteria on the TDC sensor, but as there's no such thing as a "weak signal" from the other sensor, chances are that the computer is just playing the game safely, if you know what I mean.
Besides, Renault makes more money that way....
I guess I'd require them to change the TDC sensor and reset the error list in the ECU. Then if the problem persists, replace the other one.
Getting the old parts is always a good idea.
