This is a 2017 model.

 

It used to work.

The cruse control button does nothing.

There are no error lights on the dashboard.

 

I opened the stalk to see if the unit connectors needed cleaning but this one is hard soldered in place.

 

I can't find which fuse is involved and as far as I know nothing else has stopped working

 

Help?

 

Don't touch the fuses (unless one has blown - and in that case, some proper fault-finding needs to done).  We need a scan on your car via ODBEleven or VCDS to find out where the real issue lies.  Don't touch the fuses as that will cause more problem than fix.

Garage cleared errors on computer.

These were sensor errors.

 

The distance  sensor does work and warns if too close to vehicle in front.

 

Now the cruise control still does not work. Just no response to toggle switch.

 

However if the switch is on and I signal left I get the error symbol of orange speed indicator with an arrow and exclamation mark.

This goes away when the left indicator is cancelled or cruise control turned off.

 

This is standard cruise not adaptive.

We still need a proper scan of the car on ODBeleven or VCDS to make further comments.

The garage put it onto their diagnostics.  The error that came up was sensor error, they cleared the error.  The car has been washed before they checked but after the initial fault.

 

After this they drove it, cruise controll will not activate.  The new behaviour as documented above occurs.

 

No errors appear on their diagnostics after this even though a warning light comes on when signaling left with the cruise control switch on. This happens even if parked.  Does not happen with the switch off.

 

Could be dirty contacts. Maybe worth taking the stalk off and checking.

I have fixed it.

 

I stripped the cowel off the steering column.

 

You need a no 25 star drive.

Undo the screw on the underside of the column.  Then unclipped the upper section, it will flip up.

You will see two more screws, remove these and the lower section can be taken out the way.

 

There are two silver small screws infront if the stalk base, take these out.

 

Unclipped the surround round the stalk, it has two clips infron and the circle of plastic round the slake comes free.

 

Split the stalk with a small flat head screwdriver.  The back comes off.

 

You can now wangle the wires out.

 

Unplug it from the column,  a small clip and pull.

 

You can now join the broken wires and reassemble.

 

Use a crimp if you have one but don't join at the break, this is where pressure is and it passes through the stalk.  The wires are too short and so they are tight against the plastic.

 

I used the smallest electrical block connector, shaved off the excess plastic so it fitted in the stalk and used a bigger one at the other end where there is loads of room.
