Can my battery be bad?

[thnujan0103]

now on the maypole battery charger it is showing red. I’ve got so many issues Audi A3 tfsi 2013 1.4 stronic like no communication to tcm and parking brake abs fault. Could this be because of the battery?

If you are unsure of the battery's capacity to hold a charge and don't have a suitable testing kit, may be worth getting it checked at your local tyre centre or similar, they will give you a pretty accurate status of the battery condition.
I tend to treat those sorts of chargers as only a general basis, not an accurate test of a battery's condition.

It's all about eliminating possible sources.

best of luck chap.

As it's 9 years old, it's not beyond possibility it's goosed, as rob says, get it tested by Halfords or just buy a new one from Tayna if UK based as they're the best supplier tbh.
