Hello all,
I recently bought a Land Rover discovery 5 and it has been absolutely brilliant in fact we all love it however last week we got restricted performance.
Since then we have had it come and go. After a couple days engine management line came on.
Since then my friend has smoke tested from after air box for leaks in air inline and when plugging into snap on OBD we are getting the faults as shown. Here is the interesting part which I was hoping someone else may have had experience of this and can advise. When I put my foot down I am getting what sounds like a whooshing from the air vents (more so drivers side) which sounds like it’s controlled by the accelerator, as I push the accelerator it gets louder when I let off it quiets down. This does not happen in idle therefore thinking it’s a boost thing off the turbo. I have no black smoke so think turbo is all ok and intact. Wondering if a boost pipe or a waste gate issue could be the cause of my problems and if anyone has had similar? Only thing I find confusing is why it’s kicking up MAF sensor faults when it’s after that it’s happening if turbo boost pipe etc
If anyone can help that would be fantastic and much appreciated. I don’t mind looking at things or checking just trying to get an idea of where to start.
Thanks in advance.
Brad
