Turbo Question - Maintenance
Hey Guys,
My car is getting serviced in Monrovia, CA. I take it in for this clicking noise that sounds like a rattle after I let off the throttle. They are saying it is the actuators on the turbos.... My E90 has 43K on it, using Dinan S2 & JB+ 1) I know about turbos, but perhaps not the ones on this car that well. - Can this be true? What are the actuators for on the turbo? 2) Can they make this noise? - I am under warranty, but I feel like the service contact is a f#$%ing tool^2. - Typical dealer-douche Any advice? If it is what it is, then fine, but the car performs fine. Thanx, Pissed off Last edited by MrBEEF; 09-23-2010 at 02:39 PM.. Reason: added car milage |

Sounds like wastegate rattle. Do a search for it in this forum and you'll turn up tons of info. The actuators are a common first try at a fix.

I would advise uninstalling the JB+ when you take it in as well.

Wastegate rattle is completely normal. They will try replacing actuators, updating your software (has to do with the wastegate positioning), and then if all else fails turbo swap

sorry for the newbie type question, but what does the "rattle" should like?
is it noticeable only near the turbos or through the exhaust? Out the back? My exhaust has been making a rattle type sound from the day I picked it up as a CPO.
