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.
