Hi all,
My Mk6 seems to have developed a slight judder/shudder/misfire but only when cold and intermittently. It only happens within the first 5(ish) minutes from cold and only when you drive at a steady speed, very pronounced at 20mph local roads. It feels like a very slight misfire but disappears completely once the car starts to warm up.
The strange thing for me is that there is no issues when accelerating (hesitation or misfire) and no misfires or fault codes logged in the ECU.
I'm suspecting either the MAF or a coil pack but I don't want to throw loads of parts on there without trying to pinpoint the issue, being as a MAF is around £100 and four coils are around the same.
I've tried unplugging the MAF but it wasn't that conclusive as it doesn't happen 100% of the time.
Any suggestions?
The car is 10 years with 82K for reference.
