Please May I ask guys. If I change the ECU on a 2005 Vauxhall Astra what other parts will need to be replaced to pair with it? Thank You
This from page 1 of Google...
"Whilst you can adjust and replace the ECU in a vehicle that is predates 2001, you may have difficulty with newer cars. Many of these have complex computer systems and you will have to take them into an authorised dealer to have reconfiguration work performed under the hood"
Dunno exactly how true it could turn out to be...
I'm sure some knowledgeable soul will be along soon .
Potentially a lot, its not a job for a diy'er as you will need to code some of the parts to the new ecu so requires the Vauxhall software and a little knowledge of what you are doing. Worth chatting to an expert here
No offence intended but is it really worth the time and expense involved for a 2005 Astra? Must be a special car...
It may be special, as a 2005 model, and being an Astra, it’s possible the owner was conceived in it.

Can’t comment on cars but changing ECU’s on modern motorcycles is a problem. Speedometers/ ignition are all “ keyed” to each other. I would certainly ask an auto electrician who works on similar year 2005 cars.
If it’s coded, don’t bother
Which ecu?
Lol none taken. I’ve inherited it. Service history and only 50,000 on the clock. Franky it’s the main engine control module that is suspect apparently. Thank you for all the replies as well guys.Originally Posted by Barryboy
Petrol or diesel?
Sorry was unsure which one you meant, in that case most ECMS communicate with the immobilisation system and will required some sort of security link or secure handshake to take place. If its a diesel then almost certainly injector grades would also require recoding. I cant see it being plug and play
Yes diesel Franky
Being the case, injectors would required recoding also, it wont stop them working but it'll stop them from fine tuning as every injector is made slightly differently.
You still have the security link issue so unless you have a specialist that can do it i don't think for one minute itll be plug and play
There are a few ecu repair specialists i use ecu testing . Com
