I suggest you have a look at the various pipes connecting the turbo as some of the rubber pipes are known to split causing the kind of noises you are describing.
Apologies, here in the UK we only have the straight 4 turbo diesels and the symptoms given indicate a split or loose turbo pipe. I'd still have a look around the air intake system after the air filter.2008 LR2 doesn't have a turbo it has the Volvo straight six.
I have the exact same issue and codes, but with a 2010 LR2....did you ever find what the cause was?I have a 2008 land rover lr2. It just started making an incredibly loud whistling
noise yesterday. I removed the engine cover to observe the intake system or perhaps the alternator belt as well as the power steering. the noise is not coming from either alt. or ps belts. It sounds like a loud vacuum leak. The check engine light has come on listing codes p0171 and p0174. Has anybody had this issues that could offer any tips or advice?
Thank you very much! This is very helpful! :smileI work at a dealership and my 08' Land Rover LR2 @ 87,xxx miles just started doing the whistle while idling this this past weekend.
Had a one of the mechanics take a look at it and from my understanding the PCV Valve is whats causing this whistling sound. Apparently over time the engine has a build up of oil and the part connecting it to the dipstick is making that sound because it needs to be replaced. Everytime he lifted the yellow dipstick thing the noise stopped. That said the PCV Valve is built in with the Cylinder Head Cover and needs to be replaced all together. See link below for what it looks like and what's needed:
#LR023777: Land Rover. Engine Valve Cover. VALVE COVER.
** This was the best link I could find that looks like what my mechanic pointed out/printed out for me from the parts guys.
** When looking at the link scroll down to #4 & 5 this is what my mechanic told me it is. Either way I would have a mechanic check to make sure, but the part cost me 136.00 from my part guys
Yes, it did come with a gasket....I wish I would have opened the box before I left the dealer to find that out, because they sold me a gasket separately that I had to return later lolGlad to hear you found a solution!
Quick question, when you ordered the new part (LR023777), did it come with the gasket as well?
