Evening Steve. Me again, cap in hand as I am very much at the bottom of the learning curve regards the diesel.
I have undertaken the service items I'm aware of on the latest project.
PCV filter, air filter, fuel filter, oil and filter change, intercooler rings and fan resistor.
I purchased BOSCH service items, but the filter kit didn't appear to be the correct kit when changing.
Having read this post, I am happy now that I couldn't fit the small copper washer. My concern is that there was only one large O ring for the filter housing which I changed. I can only recall the existing medium seal being present on the bottom of the filter housing, not the small one.
When finished, I started the car and the oil light went out instantly. Whilst I was initially relieved, I'm now concerned.
Do you know what size and type of o ring I need for the bottom of the filter housing, and will it be possible to remove the filter with a full compliment of oil, or will it need draining again?
Thanks in advance for your help again.
