Cruise control issue
- Thread starter H Rafiq

Could be a number of things, best bet is to plug it into a diagnostic device such as VCDS or OBEleven and get the error code.
I think that the ACC fault has car+cruise symbol, plus dirty sensor/camera warning.
Video below is most likely cause if standard cruise/mechanical fault:
I know, which is why I posted the link above. ACC fault has a different image on the dash.
Usually the cruise control will stop working if it has a fault with the brake or clutch switch as it won't know what inputs your providing.
I had this a few weeks back on my MK3 Leon and it was the brake lights stuck on. The rear washer pipe had disconnected by the bonnet release and soaked all of the electrical connectors behind the trim. Not ideal!
Have you got access to a code reader?

Hi mate what was the cause of the cruise control issue as this as just come on in my 2018 leon 1.8 tsi
its a good call to mention the brake or clutch switch. but also note that this may not show as a fault.
for example if the clutch pedal is not quite returning 1005 to the top it simply doesn't register on the switch, this wont show as a fault, rather the cruise control will simply not work as it thinks you have pressed the clutch.
you can test this by lifting/pushing up the clutch pedal with your foot as you drive and if the cruise then works ok then you can look to fix it, perhaps by adjustment or adding something onto the pedal to make sure it presses the switch ok.
on my old lean there was a plastic clip on the pedal which made contact with the switch

Have you got or know anyone with vcds/vag com or obd11? You'll be able to monitor all of the switch inputs. Clutch, brake pedal and the cruise stalk and buttons. This is the easiest way to start diagnosing the issue if no codes are present on a generic reader.
I have OBD11. There’s no clutch pedal as it’s DSG. Gonna try the steps in the video above this weekend that @black_sheep shared.
