Hi Nor74,
My S211 just threw this code on me today.
Were you able to resolve it? What was it?

I have been overdue a transmission service on mine as the last one was 5 yrs ago but been letting it drag on as only done 50K Km.
Hoping just a filter and fluid (full service) will fix it on mine. With a bit of luck, it's just the filter a bit clogged.
