Astra H ECU Replacement

**markfm** · 20th August 2014, 11:20 AM

Dear Members,

A while back my Astra H's ECU (2005 model) died at 35,000 Km. I had sent me ECU in for repair but they told me it could not be repaired. I have since got a second hand ECU and attempted to connect it to my car, but the car's second hand ECU but simply refuses to be found. I have attached some screenshots of the errors I am being given.

I would be really grateful if anyone can provide me with indications of what I can try.

I also checked all the fuses in the car with no such luck..

Not sure what to suggest, in what way did the other ECU fail, perhaps it was a wiring issue, could you connect to the old one?

Hi Pecky,

Thank you for your reply,

The old ECU was deemed dead by ecutesting.com, they sent a new ecu but after connecting its giving me the error that it cannot be found.
