    C32 Whistle Noise Help

    Well that didn't make any difference swapping the s/c pulley around, which in a way is good news. Looking towards an air leak somewhere?? Anyone know if a throttle body would scream like this...it is very throttle oriented considering how low down the rev range the noise starts and...

    C32 Whistle Noise Help

    Ok. For the sake of 1/2 an hour I will put the original pulley on this afternoon. One thing I tried last night was to disconnect the electrical plug to the sc clutch, I had no noise and no power! I'm not sure that proves anything or not relating to a leak somewhere on the intake side of things?

    C32 Whistle Noise Help

    Hi Neil, while I had the plenums off I checked all jubilee clips, pipes and Y pipe and all looked good. Throttle body gasket looked sound too. I don't know how to upload these files, I tried a zip file but too big!

    C32 Whistle Noise Help

    Update: Given the car a service and changed the oil/filter, sparkplugs and cleaned the BMC filters. Also changed the s/c bearing and taken the plenums off and replaced the gaskets with new. STILL the noise remains!! It is louder than ever, I have a couple of 6 second recordings, but can not...

    Is my tensioner screwed??

    Bish, looking at your photo again it looks like your belt is already staring to come off! I would have thought the bearing has loads of play in it.......

    Is my tensioner screwed??

    This is what happens if you don't change them! The bearing broke up and the pulley fell off. German autobahn too!!

    Neil, did a 20 mile run today connected to the EC software and returned 19 to 20 psi intake pressure at 100 throttle so maybe your software is not so inaccurate

    C32 Whistle Noise Help

    Unfortunately my noise is new but have noticed no difference in performance, it's just frustrating because once I find something I need to solve the problem! Yes they do go well :)

    Don't check very often but this morning max was 41c and average appears to be around 32c.

    Not that I noticed I tend to look at the IAT and PSI only. Also I check out if there are any outstanding or current error codes

    C32 Whistle Noise Help

    Never contacted anyone at EC, I presumed it was part of the software? To make it work though I go through the motions of starting an upgrade by selecting the file then go to data logging. It doesn't work unless I do that.

    C32 Whistle Noise Help

    Quick update. 1./ Pulley bearing appeared a little dry so packed with high temperature lithium grease. Seems quite a bit quieter and there was not a lot of lubrication when I removed the bearing covers. Not sure if that is correct or not?? 2./ Removed air boxes, TB and found the breather...

    Not properly it seems quite restrictive so like you say it maybe worth taking the tops off anyway. Would the breathers make that noise at such low revs?

    C32 Whistle Noise Help

    Hi Neil, I will probably order gaskets tonight and take the tops off. It will give me better access to check the y's etc. The noise is definitely a new one and not the whine from the sc. You can play a tune with the throttle at whatever revs the engine is running by pressing it no more than 5-10mm!

    Fitted the sc pulley and downloaded the tune myself but a good idea if needs be. Also fitted new belt and both tensioner pulleys at the same time. I will check out the breather tmrw too.

    C32 Whistle Noise Help

    Hi all, added a eurocharged 65mm sc pulley with a eurocharged tune in January and have been really pleased with the performance gains BUT in the last week or so I have developed a quite loud whistle/wizz whenever I put the throttle down more than 1/2 inch. This noise stays until I let off or...

    How many Amg owners are using winter tyres?

    Today I have fitted my Michelin Alpin's to my C32. Used winter tyres for several years as I normally drive to Czech this time of year. Through the experience of with or without the difference is amazing. especially the stopping distance!
