Bizarre running problem
Its a long story!!!!
Hope some of you can help with my problem, my 07 300 has got a oil leak that I cannot find, and my mechanic also cannot pin point the leak, so 2 days ago he was trying to find the most obvious place, I have had the new seal and pipe fitted already being worried about the swirl failures, anyway he removed the guard on the turbo to check the turbo and thought it could be the sensor next to the turbo ( not sure what it is, looking at the engine it's on the right side of the turbo just where the guard has a cut out, 3 wires coming out of it, I think it's back pressure sensor? ) as it had a lot of oil on it, he removed the plug and sprayed a cleaning solution on the area and wiped down as much as possible, he replaced the plug and covers and said run it and we will look again in a couple of days and see if the leak shows itself? Any way driving home this is where the fun starts!
The car stopped on the way home and it kangarood a bit just before as if I was taking my foot of the pedal. It started straight up and was fine going home. Later staring work I had a right problem getting the car to run but then all of a sudden everything was fine again.
Yesterday the car was ok working but on a run to Manchester it felt a bit under powered, no limp mode just not as positive as normal, anyway got back ok and had a rest for an hour then went on another run and the car was really struggling to run smooth at all, any pressure on the pedal and it just started juddering, so I finished as soon as I could.
Today been to the garage and his code reader had about 20 fault codes,all various fuel, pressure, dpf levels sort of stuff. He replaced the fuel filter which left the car still feeling sluggish and driving it hard it's ok but soon as you get to 70mph cruise speed about 18-21,000 rpm zone where it's not hard accelerating, the car starts juddering like crazy. I've been back at the garage and he cleared all codes and it seemed to be fine, a lot smoother again like a different car, but now it's started to happen again. My mechanic is great but not a 300 specialist, he says he can read the data but a lot of the time the codes only say what sensor is faulty not why and what is faulty.
It's a bit long but please has any one ideas?
