Hello folks
First of all please forgive my naivety with cars. I literally know very little about them.
I recently bought a 1.7 Astra CDTI for 5K
It keep losing power and the engine light keeps going on and off.
2 mechanics have worked on it so far and tried to address two issues: P00c7 - Intake Air Pressure Management System ( multiple sensors not plausible History & P0299 Engine under boost - current history
The first mechanic replaced Turbo Pressure Control Valve..... it didn't work
The second mechanic replaced the Map sensor....it didn't work. He also spotted the little piston for the wastegate I think, twitching and said he didn't know why it was doing that.
The Map sensor thing worked for 20 mins and then all of a sudden the engine light is back on and the power loss is back.
I'm at my wits end with this as I know little about cars and also I have a boy with disabilities that I need to transport about.
If I've posted this in the wrong place I apologise. Please help.
