Hi everyone, i own a 2010 Cruze diesel and about one week ago i noticed a whistling sound from the engine from idle to 1500 rpm when accelerating , the car has extended warranty that expires on the 15 of february , i went to the dealer but they say that it is nothing wrong with the car. I really think that the sound is coming from the turbo. I am afraid that they say the car is ok just to get rid of me as i have only one month of warranty. Can someone please give me an advice ? The car has 176500 km , i have no mods or tunnig aplied and never had. Thank you. I forgot to mention that besides the whistle noise from idle to 1000 rpm the sound of the engine is deeper and after 1000 rpm it gets normal. In december i had to take it to service because of a faulty differential pressure sensor on the dpf , the car was in regen mode and wont stop doing it . I don't know if this is related to the sounds i am hearing now. Thank you again !

Have you tried to lift the hood, and search for that whistling sound, while someone is inside the car revving it ? ... it also might be something wrong with all the intake piping, and your car, has a lot of that !

Have you ever replaced the exhaust ? you've mentioned about a problem with a DPF, they might have messed with the exhaust, and might be a leakage somewhere along the exhaust line it would explain that "weird noises" ... Bad air filter, IMHO, doesn't sound like.

 

If I where you, I would insist on a solution for this problem, and if your dealer refuses to search for the problem, them take it somewhere else, or take someone in for a drive and make them listen that noise.

Life of a turbo charger is limited and when the turbine goes out of balance of the bearings wear out the turbo starts to whistle according to engine revs. check if there is oil residue after the turbo, mainly in the intercooler and the piping. If there is oil then the turbo seals are leaking and eventually the oil burns onto the turbine blades and it goes out of balance.

Make sure the dealer has documented your complaint, and ask for a copy, at least in Australia that is enough for them to have to repair after the warranty has run out. The fact that the dealer has not wanted to repair it during warranty period means nothing, the fact that the fault is there BEFORE warranty runs out,means everything. 

 

Install a boost gauge so you can see if there are changes, whistling can sometimes be caused by a leaky hose as well and if it is large enough you see a drop in boost pressure. Cruze Diesels give 1.4 BARs boost when new.
