Hello all, my first ever post. So i have got a 14 plate mercedes c class bluetech, the car wasnt starting at all, no engine noise, looked like there was no actual connection, booked AA, they came and recommended to take it to garage. They towed it to the garage. Dealer called up on 3 different occasions saying that the mechanic needs more time to identlfy the fault, now they are suspicious of the fuse within steering control which could be faulty, they r charging it at £112 plus VAT, the only issue is they have also included diagnostic cost of 6 ridiculous hours to identify this, not sure if it could actually take up 6 hours for diagnosis?? They are going to bill me £900+ vat for this. Please help.. anything could be said/done about this?
