Where is the ECU and how to remove it
Hi,
I bought a Volvo V70 AWD 1999 and I want to know where is the ECU(Computer of the car) and how I can remove it. With pictures it will help me out. And I want to know the same thing for the MAF sensor.
Thank you for your help
Frank

Why do you want to remove the ECU?

Because the owner before me told me that the ecu was broken so I need to replace it. So where is the ECU?
Thank you

It is on the left side of the engine bay in side a black box. You need a tool to get it out. See attachment.
MAF is on the intake, right after the airfilter box, going to the Throttle mody.
Example of MAF:

Also if you replace it the Dealer needs to download software into the car to make it run after you replace it. It will not run if you just put another one in there.

You do not need the special tool. It will make things easier if you use it but you don't need it.
There are two slides on either side of the ECU underneath it. You will need to push these forward one slightly at a time. Don't get one two far forward and the other not. Once they are far enough forward the ECU will put straight up and out.

I got all the housing in my ECU compartment removed and do not see any leavers whatsoever. I drive a C70 Turbo (99/00) and have 2 ECU's, one for tranny and one for electrics. They both sit on a white plastic base and for the life of me I can't see a simple way to remove the electrics one. A diagnostics test keeps showing turbo booster sensor not getting enough voltage? hence the constant EML. I'll probably laugh at myself when someone shows me the easy way to remove the ECU. I have a Haynes manual that describes the ECU with a silver leaver for release but mine does not have this leaver/s. Any help from anyone is desperately needed. Cheers, Ifor
