valf Posted July 19, 2017 Share Posted July 19, 2017 M35 rough idle / shudder Hi, I've recenly had problems with the car and would like to know if it sounds familiar. Symtoms : - Rough idle : the car does not stall but you can definitely feel a shudder - Shudder also present when driving, especially around 2000-2500 rpm Coming from the engine 100%, it is less noticeable once the turbo kicks in but there is a slight power loss too. Problem has increased in intensity when I was driving it home. If someone could point me in the right direction that would be great. Mechanical skills close to null, if someone around Sydney is keen to have a look at it, I'd obviously pay for your time, but I can of course try a few things on my end too. Cheers!

One more thing is that there is no lights on on the dash. No engine light nothing. Not sure if the diag will show something if engine light isn't even coming up Link to comment https://www.sau.com.au/forums/topic/471304-m35-rough-idle-shudder/#findComment-7840680 Share on other sites More sharing options...

valf Posted August 19, 2017 Author Share Posted August 19, 2017 Finally received the coil packs yesterday, Started changing it today, went quite well on the passenger side (remember, I've close to no mechanical experience). I don't know where to start on the driver side though because the middle coil is hardly accessible. Can someone tell me how to proceed ? On the bright side, I've started the car and it runs perfect so I got lucky, the faulty one was one of the first 3 I swapped Link to comment https://www.sau.com.au/forums/topic/471304-m35-rough-idle-shudder/#findComment-7845450 Share on other sites More sharing options...
valf Posted August 19, 2017 Author Share Posted August 19, 2017 Here is an album, please correct me if I'm wrong. Circled in red the part I think I should remove to access the coil Circled in blue the coil I think I can't get out without removing all the rest. http://imgur.com/a/emgwp Link to comment https://www.sau.com.au/forums/topic/471304-m35-rough-idle-shudder/#findComment-7845451 Share on other sites More sharing options...
