Hi, any specialists there can advise? We have a Pug 406 with limp mode issues, it winds back to 1 cyl. and won't go at all now.
We have been told by a Pug specialist in Brisbane, Australia, here, we need the original Keycode, to reprogramme a new or same CPU. We don't have that code. What can we do please?
Not a lot of time, the mechanic has the car in the workshop now. :confused:

Thanks in advance. Wendy Shekinah

Any decent locksmith should have an contact with Peugeot system and can obtain that code in no more than half an hour, that is my experience, so you need a locksmith for that or official Peugeot service to get it

Hope this helps
Cheers

;) Thank you so much for taking the time to respond.
We are in Brisbane Australia, any idea where we will get an unlocked ECU in Australia? What cost would be expected?

Do you feel this will fix the Limp Mode issues? Everything else has been checked. and OK.

Hello you over the ditch... :)

Limp mode does not shut down cylinders, so, if it is not running on all cylinders, it is NOT limp mode. Limp mode restricts fuel supply to the cylinders and caps the rpm the motor can get to.

You also have not told us what motor you have.... petrol/diesel/4cyl/6cyl etc etc. VERY difficult to try to guess a fault if we dont have all the details. Your VIN number will help us if you dont know.

Most useless mechanics blame the ECU when they dont have any clue, it is their easy way out and will just empty your pockets. My experience is that it is RARELY the ecu at fault. The 406 is famous for wiring problems which cause all sorts of strange issues

You really need to get a proper diagnosis done with both fault codes and live readings while cranking for any chance of getting the diagnosis right. Best tool to use is the peugeot specific PP2000/Diagbox/Lexia kit. They can be purchased off ebay if you want to try yourself. A lot of us here on the forum have one, you might be lucky and find someone in Brisbane who could help. There is a peugeot forum in OZ. aussiefrogs.com - French Car enthusiasts site for Australia Since 1999 - Citroen Peugeot Renault - aussiefrogs.com & Froggy Forum!

The generic kits most workshops use are really no good at doing peugeots.

I agree its most unlikely to be an actual ecu fault and the lock key or code key is the same thing you get it from peugeot its a 4 digit code used to code the immobiliser into the car.

You cannot recode a USED ecu using the method the garage is proposing just so you understand this would only work with a new or virgin ecu but as i say i doubt you ecu is your real issue wiring is by far the no 1 reason for issues.

What Reliable is saying is go to the nearest Peugeot dealer armed with the car log book and pay for the key code. Are you sure the key code isn't written on the service book or in the car somewhere?
