Hi all. Been a while since I posted, apologies.
Anyway, I've got a mate with an E60 530d auto which has an annoying problem. He kept moaning about it not setting off immediately when warm, not all the time but intermittently. Last weekend I swapped out his thermostats because it wasn't getting up to temperature. After that I took it for a drive to make sure all was good and experienced the no throttle for a second or 2 then ok again. I got back and plugged the laptop in which only threw up codes for rough idling intermittent and various glow plug codes which have always been there since he bought it.
My initial thought is the throttle position sensor is playing up but without a fault code I'm just guessing. Anybody else had this and can shed any light?
