Do you accept mercedes w164/x164/w251 eis repair modules from Missouri?
Yes — we receive modules from Kansas City, St. Louis, Springfield, Columbia and the rest of Missouri regularly. With about 5 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from Missouri.
Is there a mercedes w164/x164/w251 eis repair shop in Kansas City I should use instead?
Most Kansas City shops don't keep the bench equipment for mercedes w164/x164/w251 eis repair — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Regional north — 1-2 days each way.
Does Missouri vehicle inspection or emissions testing affect this service?
Missouri requires a safety inspection for many vehicles and emissions testing in the St. Louis metro area. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Missouri and federal requirements.
What if my EIS is from a different chassis (W204, W211, W221)?
Those use different EIS architectures. See our Mercedes EIS Cloning (Pre-2014) service for W204/W211/W212/W221, or text us with your specific year/model.
Why is the repair more expensive than the cloning?
Component-level repair takes longer bench time (diagnose the specific failure, replace failed parts, full test cycle). Cloning is a faster data-copy workflow. For DAS3 W164/X164/W251 specifically, repair is usually the better value because finding a known-good donor for these chassis is expensive ($300-500 used).
