Is this an accurate description?

Yes mate thats exactly the situation. Sorry I didn't know it was called "Limp Home mode".

There are many reasons for the ASR light to go on, some simple and cheap, and some expensive, so you don't want to throw parts at the problem without an accurate diagnosis. Someone, you or a technician, should "pull the codes" and then you'll know what needs to be done

I spent about 2,5 hours last night to find a similar situation but couldn't find any. Maybe I should search more. I'd seen some threats mentioned about "codes" but to be honest I have no clue how should I get/learn those codes! I am sorry I am quite novice about car electronics. I am quite good to drive them (Done semiprofessional rallying in the university years) but know nothing about electronics
Could you please tell me how can I get the codes? MB dealers charge £120+VAT(17,5%) per hour laborship in London. So even just for look at it I have to pay about $280 !!!!
Thanks,
