Ok so I was driving around town boosted it then all off a sudden the p0315 and the car agent in to limp mode put a fault code reading in and came up with P0351 - Ignition coil 'A' primary/secondary. Song checked all the coil packs and opens up the fuse box and rookie all the relays out and in plunged the camshaft sensors and checked that but when I started the car again it was completely fine ? Is this a sigh of something going to go wrong ?
