As per title I had posted a thread concerning this car but as this is a new issue I felt a new thread would be appropriate. Some background info: I inherited this car from my brother who returned to Oz Had rough running due to a broken coil lead- running on one bank- but sometimes on 2, had loads of power when on all 8. Got a new lead made up by MB. Now running on all 8 but no power. Currently at an MB specialist who says the throttle body is throwing codes and he thinks it's goosed, which wouldn't be a problem except he says putting a second hand one on won't work as they are programmed for each car and finding a new one will be super expensive- £12-1300 - and hard to get too. Basically he doesn't want to get involved as he said he had a similar nightmare with an SL500. Didn't tell me the codes but I can get them if it helps. He also said ECU is showing some. What I don't get it that when it just had a broken lead it did have loads of power when it was firing on all 8 and I didn't go near the throttle body- just changed the lead. When I drove it, it feels like it has gone into a limp mode- is this possible with these cars? Any help advice greatly appreciated.
