ECU Software upgrade

I have a '97 306 XSi that has issues with cold stalling. I have tried all
sorts of remedies and 3 garages can't find any physical fault. It has been
suggested to get the software updated at a Peugeot dealer. Before I visit my
local dealer to experience their 'excellent customer service' has anybody
any good or bad experiences of a software upgrade?

Thanks in advance.

Cheers for the info.

 

As far as I'm aware Peugeot are meant to upgrade the software free of
charge if there are known bugs with the current version. Not sure
otherwise, but it will take them all of no time to do anyway. Don't
expect Pug dealers to do this automatically when the car is serviced,
they didn't with one of mine which had software issues and as a result
gave out high emissions and making passing Mots a nightmare.

 

Thanks for the info. In an ideal world Peugeot would do this, but as it's
well outside it's warranty I know I'll have to pay. As long as it cures my
cold starting problem I don't mind paying the software update fee.

I'll give it a go tho'.

 

Even after warranty they should have to do it free for because it
should have been done within the warranty period. That's providing
there is a known problem with your current software of course.

Going back to your fault, don't give up thinking that there is not a
faulty component in your injection system. I've plenty of experience
with garages and they have failed to spot the obvious. Many times I'm
pretty sure they don't even bother lifting the bonnet and just make up
some crap when you turn up. They are only interested in standard
servicing and pushing as many units as they can through their service
bays.

Go and get yourself a cheap handheld fault code reader and try and
diagnose the problem from there.

 

I got a Gunsons unit late last year as it was stalling whenever it felt like
it. It flashed up the code that indicated that the O2 sensor was broke. Got
the O2 sensor replaced. Now it stalls when it's cold. I have replaced the
stepper motor, put in a new temp sensor, checked for vacuum leaks (me and
two garages), and I'm getting very annoyed with it now.

I know there are problems with Sagem ECU's. I have to get the ECU out to
check the make. If its a Sagem, then see if it's fried and replace coils and
get the ECU repaired/replaced. If it's not a Sagem, the to Peugeot for an
ECU upgrade.

I will get it fixed. I will get it fixed..............

 

Someone posted a link to a centre that tested ECUs recently. Does anyone
have that link?

 

Try Avilec in Southampton - they tested mine for £30.
