Brera Turbo Power Loss - Here we go again
Have discussed this before on Forum and thanks for all comments and advice which I thought had solved the problem. Unfortunately 'Computer says No!!!!'
The story so far:
Loss of power and return to 'limp mode'. However, turned off engine and everything OK until the next time! (Usually a gap of about 2 weeks)
problem seems to occur when at consistent speeds for some time and then need for gear change and acceleration. It is almost as though there occurs some sort of blockage or back pressure build up which causes the turbo to shut down because of lack of air/fuel/exhaust gases, whatever
Replaced vacuum pump
Replaced Glow Plugs (because it would not regenerate DPF)
Forced regeneration of DPF which was checked to show 90% blockage before and 96% efficiency afterwards.
Everything clear and no codes showing on fault finder when checked 20th March new problem on 23rd March after prolonged high (!) speeds on motorways.
Am going to Italy in 3 weeks and need problem sorted.
Any help would be welcome. This is really spoiling my enjoyment of this otherwise wonsderful car.
