Alright guys, im new on here so hi, I've not long since got an fr myself which every now and again seems abit grumbly and bumpy when cold, I noticed it last night more than ever, I'll be honest though I don't know all that much about cars, just wondering if someone could shed abit more light on an this ecu update you've mentioned, and would the dealer sort it? The cars only done about 1500 miles and I've had it from new.
