I have been recommended to ask you guys from a mate at work who is a member on here (don't know his username).
I have a problem with my 2.0 Astra diesel. Intermittently the Turbo cuts out and the engine management light comes on. If I put my foot down sometimes the light will go off and turbo work again, seems very intermittent.
On a journey of 30 mins it may happen 8-10 times. I have got a friend who is a mechanic to plug the diagnostic machine in with error code PO400. He cannot work it out and neither can I.
Does anyone have any suggestions?
Many thanks in advance!
