Hello everyone,

Just a quick question, the previous idiot/owner of my 4.4 Vogue
decided to remove the airbox and throw on a cone
Filter, this is just loose in the engine bay, rattling around making holes
In itself, I am getting the above error codes, mostly when running on LPG,
But very occasionally on petrol, could this filter be causing the errors,or should I be looking elsewhere, I did have a hole in the exhaust when I bought the car,
But have welded this up, I was previously getting lean codes, if not the filter,any ideas?

You mean the 4.4L BMW Petrol engine. There's also a (later) 4.4L diesel - probably worth specifying in the post title which engine so people with that engine can help/share experience. 2015 Range Rover Autobiography 4.4 SDV8

That was totally unnecessary, If you read the post, it states running on LPG and petrol!

I'm referring to the title, not the content, so people scanning the forum can see which engine you're experiencing the fault codes on. 2015 Range Rover Autobiography 4.4 SDV8

There lean codes for each bank, replace that cone filter with a standard air box and filter
