Hi Everyone,

Just wondering peoples opinions on 2 things -

Excuse my ignorance (i am female with some mechanical knowledge but not as much as i need.) I just bought this car and i want to make it reliable and make it last for a long time.

1. Does a Nissan Patrol 2010 GU CRD 3.0 really need an EGR plate? I can't damage the engine by installing one can i?

2. If yes, from what i can see there are 2 types of plates you can buy, one with a hole through the middle and one without. From my understanding if you install the one without the hole in the middle it will keep your engine light permanently on? in which case if there if there is something wrong with the engine, you may not pick up on it?
On the other hand if you install one with a hole drilled through the middle, it stops the engine light coming on, but it still lets exhaust gases through anyway, which then does it mean its not doing its job?

Would be interested in your feedback/opinions

Thanks
Renee
