W124 E220 -Hesitation and Refusal to Start
For the last 2/3 years i have been experiencing an intermiitent problem where the car will start up as normal but once on the road it will start to hesitate. The hesitation becomes much more pronounced once you come to a stop and try to take of again. Once switched off, the car will not start up again but it will idle for about 10 seconds and then cut off. Giving it fuel does not have any effect on the car.
This issue happens randomly at any given time whether the engine is hot or cold and can also go for months without happening again. The problem also disappears on its own sometimes after a few minutes or a few days.
The issue recently happened again but after 3 or 4 swings it started up, back-fired a bit and then idled perfectly and I was able to drove back home with no issue.
In the past the following has been checked but made no difference to the problem;
1. Fuel pressure regulator replaced;
2. Alarm and immobilizer bypassed;
3. ECU swapped;
4. ECU flush; and
5. ECU checked for faults but none found
The engine is a M111.
