Engine starting issue
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 215ºC
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
Nick
