#1: UPDATE -- Changing the ECU (Can it be done?) Author: southwestchap, Location: DevonPosted: Thu Jul 19, 2012 3:05 am ---- Having a few probs with a 2002 D-Turbo 206, still working on it though only got the evenings with it so try and work out things to try during the day.
Just want to throw question(s) out there for some clarification.
I have no communication to the Engine ECU through PP, this could be the loom possibly. would there be a possibilty that if I had a known working ECU that I could plug it into the car and get a reply...to test the loom basically. I know that it wouldnt run but even if i got a ECU mismatch message that would be something.
This sort of leads me on to the next question.
If im unable to get anywhere, its going to be a case of replacing the ECU, am i correct in saying that I can't just get another engine ECU off a 2.0hdi 206 and put it on...even though i have access to PP could i not just recode (or whatever) the ECU to the car?
If not, what are the main componants that have to be changed together? ECU, BSI and ...? Could this come from a standard 2.0HDI Mux? or ideally from the D-Turbo Model?

#3: Re: Changing the ECU (Can it be done?) Author: LeeThr, Location: North West WalesPosted: Thu Jul 19, 2012 5:29 am ---- You need one that matches your electrical system, pre plex or multiplex. The cheapest and easiest way is to buy a complete set from the same car including ecu, bsi, transponder Ariel and the transponder chip for the key. This way you dont need to spend money on getting them re-coded.

by uncoded do you mean unlocked?

This, replace all four things from another car and it will work fine don't need to p**s around trying to unlock stuff and it will be the cheapest option, takes 20 minutes max to fit
#6: Re: Changing the ECU (Can it be done?) Author: southwestchap, Location: DevonPosted: Thu Jul 19, 2012 6:59 am ---- spied on ebay a ecu (same numbers as the one on the car), key and transponder unit...but no BSI. guessing that would be a fail still will message matey and see if he has the BSI..
#7: Re: Changing the ECU (Can it be done?) Author: Harry, Location: StaffordPosted: Thu Jul 19, 2012 7:40 am ---- You also need the transponder ring and chip out of the key if you want it to be a straight swap

You DON'T need the transponder ring, they are not coded or locked to the car, its only an aerial to read the chip inside the key.

Which is in the transponder ring..?

It's only a aerial
#13: Re: Changing the ECU (Can it be done?) Author: Harry, Location: StaffordPosted: Fri Jul 20, 2012 6:18 am ---- That's what I was referring to, must be getting names confused that's what I've always called it
#14: Re: Changing the ECU (Can it be done?) Author: southwestchap, Location: DevonPosted: Wed Jul 25, 2012 5:08 am ---- What are these "plug and play" ecu's?
I have spied a whole electronic set i.e. ECU, BSI, Key fob, Ignition ariel and BSM fuse box and all the numbers match on each part...
Though its from a 2003 SW HDi. whereas I have a 2002 D Turbo HDi...should this matter...even if all the codes match exactly?
Just waiting on a price at the moment.

Ones that have had the immobiliser function removed so you plug it in & the car will start without any coding needed.
NOTE: Your car if you fit one will no longer have an immobiliser & your insurance company can invalidate your theft cover!
#16: Re: Changing the ECU (Can it be done?) Author: southwestchap, Location: DevonPosted: Fri Jul 27, 2012 7:29 am ---- UPDATE: Managed to swing a chance to fit a bsi, ecu, fuse box, and key fob. All fitted. connected the battery as normal and done a 'soft start' of the bsi etc. turned the key (before a crank) and about 5 seconds after the center display came up with Engine Immobiliser Fault. Will still crank but still no firing.
There was no buzzing, clicks or anything from the engine area (i.e. ecu)
Plugged it into PP, got comms to everything apart from the Engine ECU.
So anyone, any ideas where to go from here?
What exactly is the box that is bolted to the back of the battery box. someone said that this provides power to the ecu? How correct is that?
#17: Re: UPDATE -- Changing the ECU (Can it be done?) Author: jordpug12, Posted: Thu Feb 07, 2013 11:45 am ---- can anyone help me get a 1.6 206 xsi ecu bsi barrel and transponder on a y plate ?
