New 2014 Pleasure-Way Sprinter Blindspot Problem
I brought my brand new 2014 Sprinter Pleasure-Way TS (chassis and the coach works are 2014 models) into the local Mercedes dealer with a Sprinter related problem. The blind spot detection system appeared not to be working. The technician used their scan gauge to reveal that there was indeed a problem with the system, but without further investigation that would entail dis-assembly of the inter-workings of dash at an enormous cost; they would be unable to determine the cause or possible solution. Since they could not determine if it were a Mercedes or a Pleasure-Way issue, the work was not covered under their warranty.
As it turns out, the system was really working as it should. When a trailer is attached to the electrical system, the blind spot detection feature is automatically disabled. Pleasure-Way had moved the spare tire to a location in front of the rear door (driver side) and had tied the new tail and license plate light to the trailer wiring loom. As a result, the Sprinter computer interpreted this connection to be a trailer and disabled the blind spot system. I contacted Pleasure-Way and they have since determined a solution to the problem. I am waiting on the corrective kit and installation to ultimately resolve this issue. Hopefully, if others with the 2014 Sprinter have the same problem and take it to a Mercedes dealer, they will be able to find help without performing the same indeterminate diagnostics. As an aside, Pleasure-Way was very helpful and understanding of the issue and has offered to reimburse the dealer's charges.
Hopefully, this will help others to avoid costs and inconvenience.
