ouups - this reply was still sitting in my browser (for several days!) - good thing I never turn my laptop off these days :-)
Glad to hear you're on the road again.
My 2.2dci had the same fault. Apparently the connector for the TDC sensor is the most probable cause.
There is a specific note (vault:4324A.pdf) that deals with how to replace the TDC sensor, which eg says that the sensor indeed MUST touch the flywheel. I had to print that, and give it to my mechanic, before they believed it. The 2.2dci engine is not very common in Denmark, - only the Laguna was imported at all, and AFAIK very few of those were actually sold - hence their lack of knowledge/training.
Anyway, when my TDC sensor failed, I got the zig-zag fault symbol (and the codes stored in the computer).
Indeed, the computer reported discrepancy between camsensor and flywheel sensor, but the TDC sensor is almost always the cause (said my mechanic) The TDC sensor is by far the "worst" placed of the two, as it sits open to the elements, under the car, however, it also means it is easily accessible - you can see it just by sliding yourself under the car behind the front wheels.
When our car acted up, it would most often start , but cut out some time later. When this happened, I could just wriggle the connector a bit, and off we go!
The repair kit has the TDC sensor and new wires, that are crimped in place - and I really hated the fact that they would cut the wires and make new joins - but as it is, it cured the problem, and we haven't seen it since.

So all in all it looks like they have billed me £139.17 for curing a problem that isn't cured at all.
Oh no! It's just not your day, I guess. Could it be that they haven't fitted the TDC sensor properly (like Lennart suggests, it must touch the flywheel - strange!)? Or a power supply problem. Perhaps as simple as a semi-dead battery... - Anders

I checked the VIN of my car (JE0KL527759757)
So did I, and my car was outside as well (September 2002) She turned off the ignition and left it off for a few minutes to let it unscramble it's brains and on the third attempt it eventually started.
Heh - a true French-car owner - not to be affected by its erratic behavior, - If you'll excuse my slightly modified Monty Python quote: "HA HA! - I spit in your general direction", - and try again - bingo ... :-) lovely. As Anders suggest, maybe they also did the wrong thing, and bent the clip "so the sensor didn't completely touch" ? My garage did that out of their general experience, - and honestly I think I would have done the same. It seems wrong to use a sensor which needs physical contact, even if it is a hall-effect thing. When I gave him that 4324A note, he raised his eyebrows in surprise, and bent the clip back into shape. He has however never been trained on the G9T, which excuses him a little. (very few, if any G9T Renault cars were ever imported into Denmark) The Renault mechanics in the UK should be trained, so there is little excuse for them not to follow the very clear directions in that note. PS: You don't have to drop the undertray at all, - the TDC sits open to the elements at all times (which maybe explains its problematic behavior) - just slide your corpus under the car - about under the front footwell, - and remember to bring some light.

lovely.
The only Monty Pythonesque thing I've felt like doing with it Lennart is giving it a good beating with half a tree PS: You don't have to drop the undertray at all, - the TDC sits open to the elements at all times (which maybe explains its problematic behavior) - just slide your corpus under the car -
Easier said than done with a belly like a bay window ..... but I got the car jacked up high enough this evening to see that the flywheel sensor had been replaced and was butted up against the flywheel. However the connector had not been changed... the harness is complete and original. Unfortunately I don't think I'll have time to get them to take another look at the problem before I head off again.... just hope that it springs into life on Thursday morning when I have a 04.30 start to Manchester airport and again after being parked for week.... otherwise I'll be more than hacked off after arriving at 01.00 after an 8 hour flight.

Hmm, - well if it plays up again, try massaging that connector. If that helps (consistently) then you have found the problem. You can also try to (carefully) bend the legs in the connector, to tighten the connection somewhat. However, on my car, I think the problem was the wires going into the conenctor, and not the connector itself, as I tried tightening it several times, while waiting for the sparepart to arrive. /Lennart
