Astra j sri 1-4t - abs light - gt1977
Hi all. Esp and abs light came on yesterday thus putting car into limp mode. Engine management light came on for a bit periodically aswell. Fuel gauge was showing empty then back up to where it should be every five mins or so. Garage diagnosis was right hand front wheel sensor. Only code that was picked up. Is this normal behaviour just for a abs sensor?? Concerns it may be ecu related. Thanks?

I'd check battery first, especially if over 3-5 years old.

It will be original battery. 2013.
Garage never checked just plugged in the diagnostic machine

Modern cars use a lot of info generated from the abs system. A faulty sensor would certainly bring on the warning lights. It could also be a wiring problem or a faulty wheel bearing or ecu issue.
