Weirdest vibration issue !!!
I have a 2010 2.0 tdi A5 which has recently developed a really weird fault. I do the same commute to work every day and after roughly 10-15 minutes of driving, while I'm on the motorway, a vibration starts through the steering wheel along with a low frequency drone. At first I thought wheel balancing but it disappears after around a minute and doesn't come back for the rest of the journey (around 40 minutes). It doesn't seem to be speed related either as I've slowed down/sped up etc but still the same. I've also dipped the clutch to make sure it's not dual mass flywheel related. I had the wheels balanced as a matter of course but still no good. Really strange fault and quite annoying, anyone got any ideas ?
Cheers,
JJ.
Re: Weirdest vibration issue !!!
At the risk of saying something stupid, could it be a section of motorway road surface, failing that have you tried swapping front wheels to back?
Re: Weirdest vibration issue !!!
The MLP platform is very prone to lower ball joint wear which causes odd wheel vibrations and we are starting to see a few racks fail due to internal wear on early cars like yours.
Re: Weirdest vibration issue !!!
Thanks for the reply Rob69 but no, it happens on different sections of road but always after about 15 minutes driving. I could swap the wheels but can't get my head around the fact it dissappears after a minute or so ??!!
Re: Weirdest vibration issue !!!
Thanks Crasher, I'll certainly have a look at the lower ball joints but still don't understand how the problem disappears ?!!
Re: Weirdest vibration issue !!!
That could suggest a heat related change in something which would normally point to a tyre, what is it on?
Re: Weirdest vibration issue !!!
So the car is a 2010 2.0 tdi Sport running on 245/40/R18. I've given the tyres a once over and no sign of flat spotting or uneven wear. I'll give the lower ball joints a look this weekend though and then maybe go for tyres.
Re: Weirdest vibration issue !!!
What make and version of tyres?

Not known for carcass issues so ball joints and rack play check first
