3. I've got Renault megane scenic 1.4 51reg. Had few problems with starting it. Few weeks ago was stuck in traffic for ages then went asda. My partner went inside i stayed in car 10min later i go start car an wouldn't start.didnt even sound like wanted start. I looked under bonnet (like I no what I'm looking for lol) then about 20-30min later it started. It was fine for for nxt 3-4weeks but yesterday I went get petrol witch is across road from my house and car wouldn't start 1st time 3rd time trying it started.then was fine for nxt few hours. We went cinema later after watching film for more less 2hr came bk to car an again wouldn't start. Sounded like wanted to but wouldn't. Again looked under bonnet. about 5-10min max later it started straight away. Drove home and haven't used car since.ive started it an starts 1st time. Sum times when start car I have to rev it little as if don't will cut out. Do you think this is the same thing in ur video? Car does need service an garage said had miss fire..sorry for how long message is .Thanks. 
4. I occasionally have this problem on my Laguna 1.9 dCi (won't start when warm, but OK when cold).
   But I really can't comprehend why doing what was shown here would make any difference!
   My usual 'fix' is actually much easier than this though ... simply wait for the engine to cool down a little.
   Usually after about 15 minutes or so, it will start OK without further action.
   I had the 'crank sensor' (not sure if that is the same thing here?) changed recently, but the fault still occurs (intermittently - about every month or so).
   In the latest incident, the AA guy said it was the 'Cam sensor' (camshaft position sensor).
   He sprayed it with freezer fluid and replaced it, and it started OK.
   So I'm now going to change that ... and it doesn't have the metal tip shown here!
   
   P.S. Couldn't see much of what you were trying to show under the bonnet.
   You need much better lighting than that to get a decent image on a camcorder. They really don't work very well in such low light.
   Also, I would suggest holding the camera more steadily ... when moved so fast it's very hard to see anything!  Ideally use a tripod, or at least rest the camera on something solid. Start with a wider shot and zoom in SLOWLY!
5. I had problems ages ago with my Renault scenic not starting, but would clutch start really easy. Many mechanics & NRMA couldn't solve it. My son in law had a peek, cleaned the crank sensor. Brilliant. Now after a couple of years it is happening again, I intend trying to fix it myself after watching this, will get back to you on this, if a 'blonde' can do it - anyone can!!!!
6. Hi Adam, I have a Renault Scenic 1,4 16v. I got to the station, turned off the engine and no longer wants to ignite. Trying to light for one second and fades. Please help
7. What does the TDC sensor do?
8. Thank you, you saved me :)
9. Hi Adam, before you cleaned the sensor was you getting an intermittant red light on the dash?
10. Why does my Clio 1.5dCi TDC work ok when cold but not when hot. I've thoroughly cleaned it, so it's not due to it being dirty?
11. Same prob with our garage, plugged it in, nothing came up so ill clean the sensor when it gets back and see how it goes.
    Thanks
12. +tango1987ful common falt u need to change 2 gaskets on the throttle body it shoud be a diy fix google it
13. I don't suppose you can direct me to the position of the sensor on a 2002 2.2dci espace? 
14. Got a 2001 RX4 and had starting issues and have just located and cleaned the TDC sensor and it has been starting no problems.  Hopefully this is the end of the no starts!
15. ciao adam  io moi trovo in italia ho visto il video anch io ho scenic 1.9 dci 102 cv 2003 ma voglio cambiare il sensore giri motore tdc  ma non lo trovo se riesci a aiutarmi grazie.
16. hi adam i have the same car and have had the same issue RAC come out as my car wasnt starting and he clean the sensor and bang in started well some days down the line am now having an issue where when i start the car it revs high around 30 ish and sometimes revs up and down up and down till the car is warm? the car also shakes in idle also sounds like maybe missfire simetimes rac guy said to me i needed to get the sensor replaced as he didnt clean the full sensor just the connection and not done so yet could this be related to the sensor? i hope so. when the car warms up its fine tho seems to run ok
17. Yes I would definitely give this a shot. These are exactly the same symptoms I had. Hopefully you get issue resolved. Adam 
18. It still surprise me, how some people don't know about Stutterolax Secrets (do a google search), despite the fact that a lot of people completely eliminated their stuttering problem with this system. Thanks to my buddy who told me about Stutterolax Secrets, I finally eliminated my embarrassment for good with natural and fast approaches.
19. it should be in the same place. Its possible one of the nuts is missing on that connector you have found. Take it off and clean the sensor up.
