Mercedes R Klasse Transmission Control Module Issue
Summary of the thread
A 2011 Mercedes R Klasse diesel with 183,000 km is experiencing issues with the transmission control module, leading to non-functional paddle shifters, slipping gears, grinding noises, slow response, and activation of emergency mode. These symptoms and error codes suggest a defective transmission control module, a common issue with the 7G-Tronic automatic gearbox. A diagnostic inspection is recommended to confirm the problem, and repair costs are estimated around 1000€. The issue was confirmed by a shop, and the control module was replaced, resolving the problem.

No recent work at all It just started out of nowhere You think it's definitely the control module then

Given the symptoms and the error codes you mentioned, a defective transmission control module is the most probable cause However, without a proper diagnostic inspection, it is difficult to confirm I would recommend consulting a qualified workshop for a complete diagnostic assessment Expect a transmission repair that might cost around 1000€, depending on the extent of the damage and whether a new or refurbished control unit is used

This sounds like a common issue with the 7G-Tronic automatic gearbox The symptoms you describe, including the inability to shift via the paddle shifters, slipping gears, unusual noises during shifts, delayed response, and emergency mode, strongly suggest a problem with the transmission control module Has the car had any recent maintenance or repairs that might be related
