wanting info please on my nightmare car faults....just been to the garage for brake pad change and new key initiation now the dash is saying theres a parking brake fault and the red triangle symbol, the mechanic has tried to clear this but cant so has told me that the whole unit needs replacing as its obviously a fault along with the dephaser at a cost of £1000, the warning wasnt there and parking brake worked fine before this, can this be cleared without replacing the whole unit??? there is also a power deficency when the clutch is released that wasnt there before!!! please help or advise as i cant afford this
