Sprinter massage seat issue resolved

My 2013 Mercedes Sprinter with a gasoline engine is giving me fits. I've got 202786 km on it, and suddenly the massage seat function is MIA. The massage setting won't kick in, and the system's throwing an error code. I'm betting it's a dodgy cable or a connector. Anyone else wrestled with automotive seats electrical issues like this? They are quoting me 95€ for a probable fix. Thoughts?

I had a similar gremlin in my Sprinter with the massage seat. Check the connector under the seat first. They can get loose or corroded. Also, did you check the fuse box? Is the error code related to the seat?

Good shout on the connector! I'll crawl under there and have a look. Which fuse specifically should I be hunting for? And yeah, the error code is definitely pointing at the massage seat. Any idea on the exact fuse number or location?

Can't recall the exact fuse number offhand, but the diagram should be on the fuse box cover. If the connector and fuse are good, it's likely the switch itself or the module controlling the massage function. You might need a workshop to properly diagnose it.

Spot on! Turns out it was a corroded connector under the seat. Cleaned it up, slapped some dielectric grease on it, and BAM! Massage function is back in business. You saved me a trip to the shop and 95€! Cheers!
