Maybe have patience with the forum. You posted a mere 10 hours ago. Is also the weekend when folks are busy.

Thanks

I apologise. I didn't mean to come across as rude or demanding. I honestly thought my wording was confusing.

I have deleted the n249 valve and have a new DV. I checked the old DV before and after removing it and it is still good. I deleted the n249 valve thinking that was the issue.

The code come back instantly. I might get a video the next time the car is home. But basically if I am sitting on the drive way, and clear the codes. The rmp rise a little then go back to where they we're (maybe 1 second of time soes by) then if I read the codes again the "Check DV" code is back.

I apologise again for my impatience

Are there 2 pressure sensors and one is faulty?

 

Have you tried the old DV. And does it pop the same fault?

 

Is the n249 still electronically connected?

 

N249 valve is still plugged in.

 

There is a maf sensor and the map sensor. Have you logged the car eg, maf, vacuum/boost maybe your maf is correct and your map sensor is low so not adding the correct amount of fuel, then the o2 sensor is seeing a lean reading.

But I wouldn't go round buying random sensors based on a guess, log the car instead. Even android torque pro cram read, maf, boost, afr
if the afr is > 1 that's too lean.
