I have a 2002 ML270 CDI - with an intermittent turn (signal) indicator problem. After about 5 minute driving when you indicate to turn (either direction) the turn signal flashes double speed. It is as if a bulb has blown, but all 3 bulbs are working. I have replaced the relays. Has anyone come across something like this before, Thanks.

If you have a towing hook on your ML, and the power for the socket back-there is on, the turn signals gets messed up if nothing is in the socket..

At least it did on my friends ML 270CDI final edition.


Hope it helped... :p

I do have a tow hitch, but I have disconnected the electrical trailer connector from the wiring harness inside the car, but still get intermittent problem, Thanks.

Check for a blown bulb. check all of them.

that could be it, I think that some cars do that in order to signal to the operator that a bulb is out, they dont put a lamp out bulb on the dash board so that could be your problem

Are you running LED bulbs anywhere by chance? That will also do it.

All bulbs are working both sides - not sure about them being LED
bulbs - those fitted are as standard, Thanks
