Some advice please.
Have just returned from away trip with work. During this time wife had to have GTA recovered by AA due to rough noise on starting.
Diag codes were for Misfiring cylinders 4,5,6 codes P0300,0304,0305,0306. and P0571 Brake circuit A.
On trying to start battery was flat. As still original battery on 51 plate started with this and replaced with new one.
On starting up again same 4,5,6 cylinder misfire codes and multiple misfire code, no brake code so presume this is old.
As 4,5,6 is all front bank together my ideas would have been poss ECU. or could there be potential mechanical damage to front bank as can hear poss knocking noises?
Alfa has 95k on clock but has had reg servicing, due one now.
Based in East London any local independents recommended?
