I agree with you

just going through the same problem the repair shop said too plastic bag the module and raise it up .

thanks a lot I will do it

A conformal coating is a thin protective film that is applied to electronic components to protect them from environmental factors such as moisture, dust, and chemicals. Conformal coatings can be made from a variety of materials, including acrylic, silicone, epoxy, and urethane. Conformal coatings are commonly used in automotive and aerospace industries to protect electronic components from harsh environmental conditions. In the case of Mercedes SAM modules, conformal coatings may be used to protect the circuitry from moisture, dust, and other contaminants that could cause damage or malfunctions. Using UV lights to check for conformal coatings is a common practice in the electronics industry. The coating material can be made fluorescent, allowing it to be easily detected under UV light. However, it's important to note that not all conformal coatings are fluorescent, so other testing methods may be required. Overall, conformal coatings can be an effective way to protect electronic components, including SAM modules in Mercedes vehicles, from environmental factors. If you suspect an issue with a SAM module in your Mercedes, it's always best to consult with a qualified technician or mechanic for proper diagnosis and repair.

In this car you Don't need it

اذا وجدت مستعمل نفس الرقم يشتغل اما اذا جديد لازم يتبرمج

@@BestCarFixes كم سيكون سعر الجديد، وهل الجديد يكون بالضرورة بذات الكود والرقم .. أم أنه يتبرمج من جديد على ولو كان الكود مختلف

If you're Able to Code it use autel or das by reading the coding from the old on yes

If not it is not going to work well like seat or gaz gage

Thank you!

Yes ofc, you need a high end scanner. $$$$

لا بعد التغيير يتبرمج مباشرة
