EML yellow light...

[romft123]

Drove the car yesterday on a 200 mile trip, stayed over night, then back the next day. Outbound no probs at all, then starting it up the next day for a return trip the yellow EML came on??? Car drove fine, took it steady at the start, did a few "sprints " up to 85, but nothing, felt as normal.

Any ideas??

2014 350

was just wondering if that happened to anyone with that car and it was...........slammed the boot, or fuel cap or...........

Not a Mercedes but happened to me on my 2005 Suzuki. Everything in the car seemed to work fine and there were no strange noises.

It turned out to be an O2 sensor but you won't know until STAR diagnostics have been done on your MB then get it fixed asap.

Not applicable to me in any way.

Impossible to say without getting the codes read on STAR, could be literally - anything.

STAR is the code reading system which will delve into more than just generic OBD and will be able to read all Mercedes codes. Expect to be charged around £80 just for the code reading.

"The Mercedes-Benz Star machine will diagnose issues with all Mercedes-Benz control units, such as engines ECU, ABS, Airbags, SRS, Aircon, Immobilisers, Keyless entry and other control units."

Some makes of car will extinguish the yellow light after several drives if an intermittent fault does not reoccur. However, I'm led to believe once a Mercedes code illuminates the EML it's likely to stay illuminated unless/until the issue is fixed/cleared.
