Professional Mechanic Tips

Field notes from Marcus Vale, ASE-Certified Master Technician
Sometimes a simple engine restart resets a one-off EPS glitch on a BYD Tang; if it keeps returning, get it scanned.
A weak battery is the number-one trigger for the EPS light on modern cars — sort the charging system before assuming the steering rack has failed.

Frequently Asked Questions

Why is the Electronic Power Steering (EPS) Light on in my BYD Tang?

Your BYD Tang turned on the Electronic Power Steering (EPS) Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.

Can I keep driving with the Electronic Power Steering (EPS) Light on?

It depends on the urgency (high) and how your BYD Tang is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
