2004 CLK ESP malfunction

[Tpower87]

Hi guys,

I have just taking owner of my dad’s 2004 CLK after his passing.

It’s due it’s MOT on Sunday and it’s booked in on Saturday. However I took it for a spin today, and the error message came up saying ESP defective visit workshop. The orange triangle isn’t on on the dash board unless I press the esp off button.

I have tried recalibrating the steering wheel with no luck.

I’m trying to work out myself what could have caused the issue? It drives fine and starts with no issues.

The battery was flat when I got it out of my dad’s garage, so flat I couldn’t even open unlock the the car with the fob. I had to jump the car from a spare battery. However it’s started every time since.

Is this a fail on an MOT and is there anything else anyone can suggest getting this sorted before I take it to the garage.

Thanks in advance.

Would suggest that is your issue. Get it on a C-Tek to see if the battery can be brought back to a reasonable state. If not then replace

Mercs are quite susceptible to battery issues and chuck up errors unrelated to the actual issue (normally the battery)

The battery was also my first thought.

Try asking on the ask an MOT tester hread about the message. I suspect it might be a grey area if there's a message but no light as the message implies a fault with the stability control system. Presumably there aren't any ABS messages?

No, no ABS messages. The owners manual also says that if the orange EPS triangle isn’t showing constantly then the ESP system is functioning.

I’m sure this is normal after a flat battery if memory serves.

Try turning the steering full lock to lock.
