I know there was an air leak which they sorted and was told that there was some oil in the intercooler that that would leave it a bit smoky but I've driven it a fair bit now (tanks worth of fuel) in all kinds of driving situations from full acceleration through to bimbling around so I would've hoped that the oil would've gone by now.
I'll give them a call on Monday and try to drop it off, but I was told it should be reliable once they had finished with it and smoke free so I'm hoping it's something simple. Was hoping you guys may help with troubleshooting ahead of dropping it off.
