Hi all, I need some help with my 2011 Sonata Limited Turbo 2.0. I disconnected my battery yesterday (Mon. 10/21) to do some wiring-related work. After reconnecting my battery I have a clicking sound coming from the engine bay when the car is set to "On" and the engine is not running. I can't tell if it is also clicking when the engine is on. After starting the car after that first battery reconnection, the car seemed to drive fine except for one major exception - it didn’t build boost at all; I would floor the pedal and the car just crawled and there were no turbo sounds to speak of. It was as if the turbo was electronically disabled or something of that sort.

Note, before I first disconnected the battery I had pulled some fuses to try and isolate the area I was doing wiring work, but I just ended up disconnecting the battery altogether. I double-checked that the few fuses I had pulled out were replaced properly.

I unhooked/reset the battery again overnight. As of this morning (Tues. 10/22), the car now drives OK and builds boost and feels normal, however, the clicking sound is still coming from the engine bay with the car set to “On” and the engine off. I've done a little bit of reading but I'm a little bit out of my league here to know what's going on. I've attached a photo of the area the sound seems to be coming from.

Maybe the sound is normal and I just never noticed before? It just seems odd with the turbo issue also happening. Any ideas and help is greatly appreciated. Thanks.

Edited 10/22 AM: Updated post; clicking sound remains but turbo seems to work for the moment.

Ryan Harvey reviews how long does it take to charge a car battery at Autofthings. If you concern, you can visit #Autofthings to get more info. It was as if the turbo was electronically disabled or something of that sort.

You try checking the turbo solenoid valve if there is bad or not. Also try looking if there is leaking boost or not. Hopefully you can figure out the solution soon.
