This is page 2 of our Mercedes fault code index. A stored code tells you which circuit has reported a problem — it does not tell you which part has failed, and that distinction is what stops people replacing sensors that were working perfectly well. Find your code below, then call us on 02920 220 380 and we will tell you what it usually means on your model. See also page 1 and page 3, or our Mercedes specialist and vehicle diagnostics pages.
