Audi A6 2015 ultra 2.0tdi auto:

Was driving and had orange glowplug light come on, car immediately went into limp mode and engine light also on. Parked the car and turned it off for couple of min. Came back and when i started car the glowplug light was there but this time with orange airbag light aswell, still on after clearing. plus TPMS warning+ ESC came on for 5/10 seconds. First thing i did was get battery tested and was told its fine ,

LOWEST VOLTAGE: 10.18v ( not sure if this ok but was told by lad at kwikfit it passed their test)

CHARGING TEST LOAD ON : 13.47 V PASS

DIODE RIPPLE :0.11 V PASS

What are your insights?

(The p2002 has been on for the past week and car is booked in to get that sorted)

The battery is not fine, it is almost dead. Ensure you get the new one coded to the car. I wouldn't trust the clowns at Kwikfit any more than those at Halfords.

Battery should be 12.4v minimum. If it’s original battery you’ve done well. Replacement is AGM type, and coded to the car, vented, etc.

I will take it to proper garage and have it tested again

Thanks

If it is the original battery from 2015, get it changed any way. It is long overdue to be retired.

As has been suggested - just replace it with a quality branded one, get it recoded, and just don’t bother to get it retested elsewhere, but worth getting the alternator output checked.

Regards,

Gareth.

Hi never mind the battery the p2002 is going to cost some dollar to fix, get a quote first before spending any more money.

You don't think the P2002 could be false because of the faulty battery Steve?
