Hi guys,not been on for a while but back again with another problem.Got my turbo changed a while back due to lack of boost and going into limp mode.Everything seemed fine but then the lack of boost returned and also limp mode.I got a full service done because i thought my filters would cause the limp mode if the fuel/oil filters were blocked.Again things seemed better after this. Just before christmas i noticed on a cold start that the car seemed to jump a bit,kind of kangaroo style and it felt like some kind of valve not opening properly.Never took much notice because once the temp gauge got to 90 then it was fine.Untill last week. The car jumping got quite a bit worse then i noticed the temp gauge was dropping.Got to around 60-70 degrees and stopped.Also felt like the car had no boost at all and was back into limp mode. Ive done a search for temp sensors which sounds like my problem but there is no mention of the car jumping with any of you guys. Would a faulty temp sensor cause the car to go into limp mode or should i be more worried.Ive had the MAF,turbo,cam belt/water pump and some other valve (amongst other things) changed all in the last year or so and i just cant seem to get the car to its best again.Thanks for any thoughts in advance.
