i had this happen on my 52 plate..it turned out it was the spark plug pack..the bit that holds what used to be known as spark plugs..its in the same place as they used to be. i think its called an electronic pack. i know this, that a gen part is very very expensive so my mech/tech found an after market replacement for less than 1/2 the price of the gen part! it came with a years g/tee as well. the thing is ,as its moulded in one piece,you cannot change the faulty part, but for the price i paid with the g/tee for a year, i got a year free of worry, and my mechtech said if one had failed the others would have followed so even if he could have just swopped the faulty part, it would have cost more than the whole thing. hope this helps,all i have to do now is find someone to tell me how to fix my roof lining drop..its getting worse!!
