Recently my sky on cold start has been producing a disturbing wheezing sound from the engine bay. This only occurs on cold start up, once the car is warmed up it goes away. The wheezing sound, tends to go higher as i accerlerate more, it's like its letting air out. btw the sound is quite faint but its annoying the shits outta me...

any help will be appreciated

thanks

Can you get in there and find the sound?

what about boost levels when it is cold, do they register lower?

i have a little theory: perhaps your inlet gasket/plenum is loose, and needs the heating up process to tighten the gap, it alloy so shouldn't expand much, but it may be enough!!!

anyone else got theories?

I'm not sure, cause i don't really hit boost until the car is fully warmed up, by then the sound is gone, but i'll have a check tomorow morning....

Gts4, yea, i'll have a look at the belts and get back to you all

Thanks for the help Craved and gts4

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.

      Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
