Thank you. I will book in the car with Lexus tomorrow morning I just hope they don't suggest the battery instead of a smart battery sensor unit as it is considerably much more expensive ( sales commissions on parts etc).

Hi Thomas, I will take it to Lexus but I had the emergency breakdown company known as the 'AA' here in the UK and an independent Lexus Hybrid specialist identify the POA80 fault as a faulty Hybrid battery. Can you please advise if this fault code is related to an inaccurate fuel gauge level and low thermostat level or would these be independent of the POA80 fault error?

Sorry I made a mistake. ERROR code is POA80 and not I have just had a similar issue. I bought my car 1 month ago from a car garage. Everytime I drive fast around 80 miles per hour- the "Check hybrid system" and "Check VSC system" messages appeared on the dash. also engine management light comes on. I called the AA recovery service and they diagnosed fault code POA80 relating to a faulty battery pack. I had this problem before and had the faults reset a week ago by an auto-electrician. Just as soon as I speed the messages re-appear. Is the above related to a battery pack and if so is it possible only replacing the faulty cell rather than the whole Hybrid battery? Can the above related to a faulty mass flow meter / sensor? As the fault only arises when I accelerate at speed on the high way and not when driving slow in city traffic? The place where I bought the car from is not willing to address the problem as the car is outside of the warranty perioved by 2 weeks. Car is a 2005 vehicle with 98000 miles. The car was parked on the drive for 4 weeks as I was on holiday during the warranty period :-( otherwise I would have raised the issue with the car garage earlier Any advice would be most welcome.
