ESM Solder joints. Need to send it out.

Hello, I need a referral to a company/group I can send the shifter to so that the ESM board can be resoldered. The shifter won't go back into neutral and park from Drive. Have to use the parking brake, not the main pedal. Also, keyless go won't cooperate as it says must be in park in red, when it is in park.

2007 SL550

Thanks in advance.

Dry joints in the shifter will throw a code, probably P1856.

This code is a pretty sure sign that the optical sensors in the shifter need to be resoldered. If you can get the shifter out then any electronics technician should be able to resolder it. You need a temperature controlled soldering station with a long thin tip.
