Hi
I have replaced my R170 Headlights and Indicators with a pair of Sonar combined units. The new headlights only have manual adjustments for the 'Up & Down' and 'Left & Right' beam adjustments so I do not need the pneumatic connections that went to the old headlights. Can these pneumatic lines be left unconnected or do they need to have their ends sealed up?

Any help appreciated as always.
Regards

I would definitely seal off any unused vacuum line. If left uncapped/unsealed it will result in false air being sucked in. Whether this will lead to any serious trouble, I do not know - but it will certainly not do any good
