Frequently Asked Questions
Why is the Hill Descent Control Light on in my Aston Martin DBS?
On a Aston Martin DBS, the Hill Descent Control Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Hill Descent Control Light on?
It depends on the urgency (low) and how your Aston Martin DBS 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.
How much does it cost to fix the Hill Descent Control Light on a Aston Martin DBS?
Cost varies widely because the Hill Descent Control Light can stem from several causes on a Aston Martin DBS. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Hill Descent Control Light reset itself on a Aston Martin DBS?
If the trigger was temporary, a Aston Martin DBS may turn the Hill Descent Control Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
