I have 2003 2.5tdi which has engine warning light on. I have had code reader on it and there are 3 active faults. EGR p0401 insufficient flow, p0048 turbo boost control circuit A high and p2108 throttle actuator. Car has been remapped with egr delete. No very noticeable physical symptoms, but i have just bought car so its hard to say if its running worse than it would normally. Has anybody seen this combination of codes? or have any suggestions/likely causes? thanks for any help!

The engine light can be activated when the tube from the egr is disconnected, it was around your year of car that they changed mine is a 2001 and it doesnt throw an angine light when the tube is removed, when you say egr delete are you saying it has been blanked or actually remapped out as it sounds like it has plates and the engine management cant detect enough gas flow. cant help with the other 2 sorry
I'm told it has been remapped out yeah, but valve has had vacuum pipe removed as well. Will look closer to see what's been done to egr. Was thinking all 3 codes might be related to 1 fault. Thanks for info though.
