Vauxhall Astra rattling/knocking
Variant: 1.7 cdti (100) Design
Model Year: 2005
Categories:
Running Rough, Starting & Power Loss
I have a rattling and knocking noise coming from the engine. Its been to a few garages/specialists who have all charged me a fortune and not fixed it. The noise is only noticeable under load or acceleration. I have so far paid for the dual mass flywheel and clutch replacing and the diesel injectors testing and cleaning. This has made no difference. It sounds like a pre ignition knock with one of the injectors and that appears to where the noise is coming from, but theyve been checked and cleaned and ive been told theres nothing wrong with them.
My car has done 60,000 miles.
Any thoughts?

The 1.7 engine in later common rail type injection system are notorious for injector noise,
I am a Vauxhall tech, we get lots of high mileage fleet cars with very noisy injectors and they just keep on running.
You could possibly make sure they are coded correctly at a main dealer, they have numbers on the top of injectors, which should match the code programmed in the engine ECM.
Another idea would be to get the small quantity adjustment checked/ programmed.
If its not horrifically noisey you could ignore it!
Hope I helped a little....
