Hi


Went away for 3 weeks so my E220 didn't move. When I came back it was didn't start immediately as it usually does, took 3 attempts. I then drove 15 miles to my parents and stopped for an hour, it was even more difficult to start, about 6 turns of the key. On the way home the Engine light came on.


Now, once the engine is warm it will not start at all so I have to sit and wait for it to cool for about an hour. Luckily I have a hand held OBD reader so I plugged it in whilst I sat and waited but it says there are no DTC's and all the data reads wrong.


The Calc Load is always 100%


Coolant temp is 215ēC
MAP is always 255Kpg
RPM is always 25% of actual engine speed
Speed always shows 255 Kph if the car is moving, 0 if stopped.
OBDSup says NO OBD


Bearing in mind that this has happened during a period of not being used, any of you experts have an idea what it could be?


Thanks

Well if the engine light came on, you therefore have a stored fault that your substandard OBD reader can't read---that's the first problem--get a better reader and post the fault!!
