Vauxhall Astra H (2005) 1.7 CDTI (100BHP)
I recently replaced my oil cooler and a water pipe and in the process took off the lower metal air charge pipe which goes from the inlet manifold to the EGR I guess? This had quite a bit of carbon so cleaned out what i could and same with the inlet manifold where it connects and the other end.
Whilst replacing all this i accidently broke a leak off pipe connector. When I finished everything I went to start it to see if all was OK. It fired and ran for about 2 seconds then stopped. Now when i turn it over it makes a higher pitched whiring sound, nothing like it should sound. I checked the cambelt and all OK but it seems like there is no compression.
I replaced all the leak off connectors and pipes but that has not helped. I plugged in opcom and the only fault codes were p0070-71 and p0500-74. I did a live data test whilst cranking the engine and will post that here if it helps.
Anyone got any idea why this has happened and how to solve it? All was running great previously. I suspect some carbon has gone in the inlet manifold and blocked all air to the engine, is this feasible?
Thanks in advance.
