Re: ECM-644A 2000 volvo c70 coupe t5

Ok great, Am I correct in reading the 2.3l hpt engine should be timed with the exhaust 1 tooth retarded?
Many thanks, Dan

Re: ECM-644A 2000 volvo c70 coupe t5

Had a good read and was very informative, was just wondering if you used any of the specialist cam/crank locking tools as ive heard they are very helpful but not 100% necessary.
Many thanks, Dan

many thanks,
Dan

ECM-644A 2000 volvo c70 coupe t5

Hi all, I recently checked my vida for the first time and found code ECM-644A Camshaft control - Faulty position. I then checked the camshaft nominal vs shift angle, at idle the nominal angle is 15 degrees and the shift angle slightly fluctuates around this (+-0.5 degrees) however when on throttle t...

Muddy Dolby pro logic SC-901 2000 c70 coupe

Hi guys,
My SC-901’s Dolby Pro Logic mode sounds really muddy and faded compared to normal stereo and 3 channel modes. Any idea what could be causing this or what usually fails in these units?
Many thanks,
Dan

CV Questions

Hi everyone, The passenger cv shaft in my c70 has started to go and needs replacement and I had a few questions. Does the cv from the 850 fit the c70? Or are the dimensions different. I have seen mentions of people rebuilding their own cvs and I was wondering if there was a kit to do this? Many than...

Creaking when I engage throttle/scraping from front wheel 1999 C70 T5

Hi guys, Noob here. I have a 99 C70 coupe T5 with 270000km Issue 1: There is a creaking/clicking sound that happens every time i engage or disengage the throttle, there also seems to be a small amount of slack before it engages. The sound is definitely loudest in 1st but still happens in other gears...
