Resolved Question:

Hi, I've got a 2008 corsa 1.3 eco flex diesel which only recently has developed a flat spot when accelerating. Also occasionally there is a like a rumble coming for engine bay on start up. Do you think a diagnostic test would tell me what's wrong? there are no warning lights on at present.

Welcome to Just Answer, This sounds like quite a common fault on the Z13DT engine and is normally due to the waste gate on the turbo that is starting to seize/stick.

As there are no warning lights then a normal diagnostic will show "no fault codes" but a test on the operation of the waste gate using a vacuum /pressure pump should show the fault, if it is sticking then they can usually be freed off.

I hope this helps, best regards, Vauxdoc.
