DASH WARNINGS MOT FAILURE ?

[Delboy0127]

Factory Fit Deployable Towbar removed following unrepairable failure Detach Towbar and electrics fitted Adviced at time dash board warning would need to be removed by Mercedes Star system. Car went in for service and was set up on star Mercedes advised could not remove warnings without switching off electrics to new socket fitted. Just booked car in for service and MOT this year in June 2025. Mercedes have emailed me enquiring have I got the dash board warning problem resolved ? as the car will fail its MOT. Any suggestions please to correct the problem

I'm just guessing - seems like a major safety item warning and IMO, it will fail. As I am not a mot tech/mechanic I'd wait to see what others state.

This warning relates to the faulty factory fit deployable tow bar that has been removed

In that case, it may not be.
If no one gives a definitive answer to the question here - when you have a mo, just go to a garage that does mot's and ask.

As long as its not a danger you are good. - my MOT place told me this a couple of days ago.

Only the EML is an MOT failure, other errors are taken as advisories (unless they result in something dangerous) - you should be ok in this instance as you arent actually towing.

Last year the car was put on the Mercedes star system to try and remove the warning, it could be switched off but it then switched off the new towbar electrics altogether. This was done to pass the MOT on the car. Obviously this year for MOT the car will not be connected to the Mercedes star system , Hence when booking my next service and MOT, by return email Mercedes enquired had I resolved the dash warning light for the `towbar? as this will fail the car MOT
