I had the dreaded coil and engine management light come on last Tuesday and when I plugged in my Carista it came up with codes P029900 and P2279 - turbo underfoot and air intake leak. On the way home that night it lost most of its power and as I pulled over I heard a horrible hissing but no fluids leaked. Once recovered from the side of the m66 I got it home and started the engine, alot of air and smoke looked like it was coming from the bottom of the charge cooler. I managed to get it booked into a garage (it's now been there for a week) but they are struggling to get the standard part as apparently it has been superseded and costs nearly £1200 just for the cooler, brackets and extra pipework needed to make it fit. Has anyone else had this issue?
