Volvo Repair Questions? Ask a Mechanic for Answers ASAP
To have all of the ECU's on a vehicle replaced will be extremely costly. If you take the vehicle to your local Volvo Dealer they will be able to fit a new unit and carry out the necessary programming and configuration in order to get the vehicle working again.
I would be extremely worried if you can buy a full ECU kit for that price. Have you heard if the phrase 'You get what you pay for'?
You're opening up a can of worms getting an ECU kit like that! Go to the Dealer they will fit the one module it requires and carry out t he necessary programming and configuration!
I will never tell anyone to fit a substandard part of dubious origin that will in all probability give you even more problems!
