Hello, my 2001 A2 has two faults, the first is a symbol on the dash of an oil can and the word sensor on it, the symbol is orange in colour, i understand its a warning for low engine oil, the oil is okay as it can be checked on the dipstick, can`t find a sensor on the sump, sometimes the fault goes off and the ambient temp display comes back on as normal, has anybody had this fault?.
My next fault is a sudden loss of power-as though the turbo has stopped operating, i have changed the MAF sensor and this seemed to improve the car, the fault only seems to happen when on the motorway and accelerating to overtake, i have been told this is now a turbo problem with it overboosting and then the engine ECU cuts the power, again anybody had this problem, any info gratefully received, thanks Andy.
