Saxo diesel power loss

I had a similar problem with my Saxo. Any recent chip tune or work done? Reduced power and an error code could mean something's messing with the car's computer.

Yes, the previous owner mentioned chip tuning. Could that be it, even if it was done a while ago?

Definitely possible. Aftermarket tunes can cause issues, especially if not done properly. After a while, the chip might degrade or throw errors. Take it to a workshop with diagnostics tools to confirm. They can check the chip and if it's causing the engine issue.

Workshop confirmed a faulty chip tune. Cost 180€ to sort. Thanks!
