CGMB～How to replace EIS W221

[@tomking3942]

I had a eis 215 that had a 220 board inside. I could not read by obd or on bench. Is that a problem eis?

Read the eis with programmer on bench . then upload data to cgmb.

Have to replace EIS from W164 after 2009. Any advice on how to choose right replacement (donor)? Does any w164 after 2009 donor will work? Thanks.

Hi，you can not use any eis you want, better to choose same eis number .
