My Megane scenic would not start due to no central locking working int SO the immobliser cut in, so here can be found a usefull program to obtain your personel code to start the car and get you home.

A good post and a useful tool.  A little more advise, if you enter the code as trantir++ it unlocks some aditional menu's.

If your car only starts for 2 seconds it means you have not switched off the imobiliser and the dashboard light will be flashing.

When you unlock the car via the remote infra red key, the car imobiliser should switch off also, this will be indicated by the led on the dashboard the led will go out and no longer flash.
start the car quickly, If you do not start the car within 10-15 seconds the led will start to flash andthe imobiliser will come back on. so lock and unlock the car again whilst sat inside the imobiliser should now be off again.

Inside the key there will be a label with 2 rows of numbers printed on the white label please try both i think it was the bottom row

the 4 digit code may be printed on a card in your owners handbook pack.
or most garages may be able to turn off the immobiliser in the diagnostic software.

The number of the key is printed on a piece of card and placed inside the key.  Almost always it falls out and cannot be found.  Also sometimes it is printed on the plastic case.  It will never be written in the service book or owners hand book.

Remember this calc only works 100% for cars up to 1997 and may do cars up to 2000.  After 2000 the pin code uses letters and numbers so Trantir will not work, also you need diagnostic tools to enter the pin code.

If you open the ECU and read the Fairchild 24c02 and post the dump I will make it immo off for you.  You must use hot air to desolder the 24c02 as it is glued to the board.  Then you can program my modified dump in to a new 24c02 and lift pin 7(WP) and pull high ( you can connect to pin 8 - vcc).  This is because pin 7 on the original fairchild I2C is pulled low internally so you cannot write protect it and if you do not write protect it then it will upload the original dump from the processor.  When you have done this you must cut 3 wires from the ECU.

Send me the dump and Bosch ECU number 0 281 *** *** also how many plugs the ECU has.

No garage can turn the immobiliser off with diagnostic software - it just is not possible, can only be done by I2C in the ECU.

...Or post me the ECU and I will do it for you.

If you prefer the immobiliser emulator from ebay that Tmg suggests then I can supply it for 65 inc carriage and no VAT to pay.

Sorry, that is the later ECU ( ithought it was the early one).  The decice in this is 95p08.  it is marked 5P08C3 and is ST.

Seeprog is the best tool to read this with (around 50stg) from crownhill associates - or I have a schematic.  Sometimes it will read as 95080 on programmers which do not support 95p08 but it is not 100% reliable.

If you cannot find the 95p08 ask and I will mark it on the photos you uploaded.

If you wish to buy a programmer then seeprog is the best, but you cannot buy it from Crownhill any more and I do not know where to buy it.

If you wish to build Seeprog yourself then I can send you the schematic and.brd file so you can etch your own PCB.

Or you can send me the ECU and I will read and program the 95p08 for you.

Or if you wish to fit an emulator then you must remove and open the UCH.  Inside is a 93c56 (I think, or it might be a 93c56).  Read this and send me the dump and I will program you an emulator from your dump and send you fitting instructions.  Otherwise you must post me the UCH and I can fit an emulator inside for you.
