Mine has been hissing and sounding like a police siren for the last 5-6 years. Remapped also.
Pulls well and no errors.
Does not bother me anymore but people in the street will sometimes turn their heads :busted cop:
Just back up the original coding before making changes and make sure you read up on modules you want to code as there are different versions depending on car spec and year.
Short journeys with lights, radio, rear window demister on, cold weather.
Not enough time for battery to charge.
It's easy enough to remove with the right tools and if charger can fix it then I guess it's better than getting a new one.
Hi.
I have contacted Tayna and described issue I was having. They responded with details on how to return the battery but also mentioning that battery might be simply discharged due to cold weather, short journeys, lights left on etc.
After advice from @NHN I have decided to buy CTEK charger...
I believe it does, canbus comms in OBD port stops as soon as ignition is off but it could be that the dongle still draws power. I'll remove it for when the car is parked.
Recharged the battery with CTEK overnight and the car started with the first crank.
Might have a similar problem with something draining the battery. I got xcarlink plugged into the stereo and Bluetooth dongle in obd port to work with torque app.
As far as I know both devices are powered off...
So just had my Varta E44 fail after 4 years. It's guaranteed for 5 years so in theory I should be getting it replaced/refunded.
It has been a great battery up until today.
