Sooo whilst taking the car for it's gearbag service we had a symptom repeat it lost 2 cyls whilst on the A1M at a steady 70, just sudden drop to 4 with a loss of power. I stopped it quickish (not the most fun in the world sat on the hardshoulder) and aside from the odd smell (fuel into cat?) I found no faults again no lights lit and everything full so I called it names, started it and it was fine, drove another 30 miles before getting stuck in traffic litterally 3 mins from destination and 4 cyls again. Figuring it could only be the coil getting warm and losing 1 of the 3 units feeding 2 cyls. I took my emergency spare with me when i went to pick the car up, did a roadside swap and it drove back absolutely perfectly (the gearbox obviously was super smooth) with what felt like more power and possibly more economy suggesting it might have been in declining coil health for a while (i usually only do little 6 mile hops to work, not long enough to get warm and loose the cyls) I took it back to supplier who have very kindly agreed to replace it (its heading on for a year old so I think they're being quite sporting really) but I have to wait for it to arrive so I might have got this little unreliability patch sorted. My fingers are crossed!
