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?
I have the exact same issue and codes, but with a 2010 LR2....did you ever find what the cause was?
