ECU unlocking/decoding - Saxperience

Waz · 1st July 2008, 15:15

easy people!
I have a vts with a kepad immobiliser, when i bought the vehicle the immobiliser had been disabled, so basically i dont need to enter a code to start the car, the problem i have now is i dont know what this 4 digit code is to be able to do a diagnostics test. the ecu will not allow the diagnostics machine to enter the engine management menu, it says there is a communication error.

Now any have any tips for me to get around this problem and have access to the engine management without getting another ecu?
Or could anybody giv me some company names and contact details where i can get my ecu reprogrammed?

could give bluehawk (eletrics or electronics), they unlock ecu's bout £100 i think.

his ecu is already unlocked if hes not using the keypad.

ring citroen for the 4 digit code.

although when i got the code from citroen and tried to run a dianostigs on my ecu, the same happened to me.....

i have spoken to citroen and they dont know what the codes are and there is no way they can find out, they also say the standard codes are 1111 or 0001. i have tried them as i got pissed off and thought id attempt them, now the red light and green lights are solid when i turn the key i enter the codes and nothing happens, now can somebody tell me what is supposed to happen? Im guessing the red light should turn off and the green light should stay solid until the engine is started?

i can unlock the ecu but i live in Greece...that's a problem

lol, a big problem. I have managed to get the car started but it turns off after about 2 minutes. Now i have replaced the gearbox crank sensor and im guessing my problem of the car cutting out and the engine management light has something 2 do with that, now i think i have the sensnr sat in the right place otherwise the car shouldnt start. The gearbox i have on the car is a 1.3 rallye box, would that have anything 2 do with the crank sensnr, as in the new sensor i have put on is for a vts box. Do i need to get the senor for a 1.3 106 rallye gearbox?

in regards to the engine management light, i think ive figured out why that keeps appearing and y my car keeps cutting out, my induction kit was touching the posative power port on the battery, thats y the car kept cuting out. Lol something so small but major!

s34n · 27th December 2010, 23:37

ryanmt · 27th December 2010, 23:58

have you got access to the old keypad+keycode? If you can try find somebody with a keypad vts and unlock it that way, or send just the ecu to me and i can unlock it for you.

wparker_tfr · 28th December 2010, 10:41

Ryanmt, can you still unlock ecus? If so can u pm me with the price nd what u need? Thanks

Would an unlocked ecu cause power loss wen u first get goin after a few minutes it's fine advice would be gd

No, not unless the ecu itself is shot.

Furryurchin · 7th September 2011, 20:23

could it be a remapping problem? how much would a replacement cost its doin me head in also what else would it intail is it possible to do it myself

ryanmt · 7th September 2011, 20:30

You can buy a replacement ecu and fit it yourself. The remapping if very poorly done could cwuse the issue

Furryurchin · 7th September 2011, 20:35

would i not need to get it synced to my emobiliser or jus unlocked as i dont no much about this process as i bought the car already done id rather jus change the ecu then try remapping it
