Many thanks to both for advise, I hope that both the recovery people & mobile mechanic checked the battery/alternator charging etc as that would be the first thing I would do & I am not a mechanic. The mechanic did say battery OK but how far he checked I still don't know, I think this is after driving somewhere and not first thing in the morning so really would assume not a charging issue as after standing overnight that would be the time most likely to struggle and it seems it either turns over really well or not at all. I would have not believed the TM button in a million years would have anything to do with it and why the mechanics went to it, I don't know but to my astonishment fiddling with it does seem to make a difference but again could be just coincidence. Next time I will get my daughter to really analyse what she is doing but assuming it was OK this morning as not heard from her. It does sound a bit like a bad earth or starter. Thanks again.

C5 2001 Stop & Service - Won't start. TM Button ?? intermittent c5 exclusive se hdi manual diesel 2.2 2001. HI Daughter has the above car & 200 miles from me so I can't experiment too much & being my daughter information is a little vague! Had few months & been OK. New MOT & Service & know full 10 year history. During the day had driven a few short journeys OK, later went to shops, came back to car after about 1 hour and would not start. Stop & Service Warning & engine management icon. nothing else. Would not even crank at all, she did say there seemed to be click behind the dash on turning the key. Called breakdown, eventually turned up, don't think they got a fault code, originally thought it was the battery but later not (Don't know why they changed their minds) but they did jump start OK. Not really sure if warning lights had gone out or what but I am 99% sure the battery is quite new & OK and especially as just driven. I think it generally is OK when started new, i.e. first thing in the morning or after some hours. Does it V.Approx 1 in 3 times but runs fine once going & does not stop. Called an auto mechanic out, no fault codes either. He advised to press the TM button, which seemed to fix for a short while. Could not find anything else as this temp fixed it. not being there not sure what else he tried. Did fail again following day, fiddling with TM button seemed to fix it but NOT straight away but was in some minutes. I am amazed the TM button could have any effect unless a short but there does seem some effect unless big coincidence. One thing I wondered, I believe there is a small leak from hydraulics "Misting on suspension" in MOT "but not enough to be a problem" Could low pressure be sensed & full prevent of start. I really don't know if levels were checked but I did mention to auto mechanic. Could the Raise/Lower ride height buttons cause this if pressed. Sorry so many vague points but not sure where to go, don't really want spend a lot at proper Citroen garage and not being local hard to know if you are going to get a good auto electrician in Leeds. Can the TM be disconnected or switched off, she is not getting any messages as far as I know & doubt subscription to it for many years. Thanks I/A
