Hi,
I have question regarding difference between electric Citroen Saxo and Peugeot 106. My Saxo is equipped with Y1000 series Sagembox while P106 with Y3000. I have noticed that braking lights on 106 do not come on when braking with regen. I found on the net on the several places that it could be really so. Is that really true?

How is that possible? Regen braking is really strong, capable of inserting almost 20kW of power back into the batteries and to deliberately remove absolutely useful feature that was already present is earlier designs, is unbelievable. Or, that feature is only present on Citroen vehicles? Both assertions are equally idiotic. 

Can someone confirm, is that really true? Does anyone own Saxo with Y3000 Sagembox, is it behaving the same?

P.S. I am focusing on Sagembox as main culprit but could it be that ECU version has something to do with it? But again, I doesn't sound logical - I have older ECU while Peugeots have newer ones (4.2).

Hei ,
Jeg har spørsmål angående forskjellen mellom elektrisk Citroen Saxo og Peugeot 106. Min Saxo er utstyrt med Y1000 serie Sagembox mens P106 med Y3000 . Jeg har lagt merke til at bremselysene på 106 ikke kommer på når du bremser med regen . Jeg fant på nettet på flere steder at det kan være virkelig så . Er det virkelig sant ?

Hvordan er det mulig? Regen bremsing er veldig sterk , i stand til å sette inn nesten 20kW av makt tilbake til batteriene og å bevisst fjerne absolutt nyttig funksjon som allerede var til stede er tidligere design , er utrolig. Eller , er at funksjonen kun finnes på Citroen biler? Begge påstander er like idiotisk . : o

Kan noen bekrefte, er det virkelig sant ? Er det noen som eier Saxo med Y3000 Sagembox , er det oppfører det samme?

PS! Jeg fokuserer på Sagembox som hovedsynderen , men kan det være at ECU versjonen har noe å gjøre med det ? Men igjen , ikke jeg høres ikke logisk - Jeg har eldre ECU mens Peugeots har nyere (4.2) .

First of all, please observe that the Y1000/Y3000 plate is sitting om the lead, so you cannot be sure that is belongs to the box itself. Secondly the PCU (computer on the left side of the box seen from the frontseat) can also be swapped.
As far as I know there are several different software versions on the PCUs, and no one knows the difference between them.

Thereby you cannot tell which version you have in a car by looking at the Yxxxx og the make (Saxo/P106) or yearmodel of the car.

I can confirm that some cars does lit the braklights when regen and som dont.

I didn't know that. Thank you for the info.

I'll guess some simple external modification will rectify the issue. (when regen current is greater than, let say 20A, short brake pedal switch).

If you build such a device let me know, as I would like to build one to put BMW i3 into neutral as soon as regen starts as this car does not have a auto sailing option.

In my Saxo which originally had the Y3000 series, the lights did not come on under regen braking, but after swapping to Y1000 series (came from a 106) I noticed that the brake lights come on with regen braking. So maybe the feature was purposefully removed on the newer series, or it could just be a glitch in the software.

But as Elmo mentioned, the ECU can be swapped so if you bought your car used, you cannot be 100% sure that the series number you see on the outside of the SAGEM box is what you get on the inside. Or, like mine could have come from another car carrying a different badge.

As far as I know the brakelight on regen was removed approx 1998/1999, but I have no idea why.

[elektrolux]

I think the constant flickering of the brake lights in busy traffic was not desirable.

Driving behind a car like this is stressful, and will result in cars constantly trying to pass what they believe is a drunk ore unskillful driver.

I think..

Would it not be OK if brake light is on when the speeder pedal is in "neutral" ? (only if the car is on, it must be possible to find a fuse that only has voltage on when motor is ON, to take the relay voltage from ).
That would be pretty easy. Only relay and a sw is needed on the speeder pedal..
This could be used:

I would not dare "play" with the speederpedal. The car is extreemely fussy with the resistance on the pedal and its cord !!
And remember that the car does not start (no click) if you touch/press the pedal while turning the key.
