Hi
Wondering if anyone could help. Had a rattle from the engine recently which resulted in a general loss of power. Ok on the flat but struggled on the hills barely getting above 30 miles per hour. Took it (several times) to a garage who eventually changed the inlet camshaft phasing pulley as well as cleaning out the solenoids/oil change/general service. This seemed to fix the issue for a while but it has now returned, although intermittent. Sometimes it will drive normally, at others it will struggle to get up hills with no clear pattern. Took it back to the garage who pulled everything off again and couldn't find any issue. Does anyone have any other thoughts? Do I need to replace the solenoids? I think only one of the pulleys was replaced, and I notice in the sticky that two should have been replaced - what does the second pulley do?
Any help would be greatly appreciated

Hi,
I see you have read iGaz thread on VVT engine noise. One of the pulleys is inlet and the other is exhaust. As he said in the thread the inlet camshaft phasing pulley was the one that caused the problem, but ideally you should get them both changed together as the other one is also likely to fail shortly after which is possibly whats happened to you. This will mean all the same stuff has to come back off just to replace the other pulley which would have worked out cheaper if you just got them both changed at the same time. So you will pay almost the same again for pretty much the same job just a different pulley.

Hope this helps

Thanks gotta.turbo.it. I was worried that this might be the case. The engine fault light came on once, but hasn't come on again. Tried the pedal test multiple times but can't seem to get it to work so not sure about fault codes. Think I might have to look at replacing the exhaust pulley. Willl have a close listen as I think there might be a rattle again, will see if it is coming from that one.

I wouldn't assume that the exhaust pulley has failed just yet though although its possible as you never got them both changed. As marks said check if there's any fault codes stored first before splashing out money on a part it may not need if its being caused by something else.

If the noise is as bad as it was before then it's either because the solenoids weren't replaced or you've been quite unlucky and the exhaust pulley has failed all on its own. It's always advised that you change all 4 parts at the same time. Changing just the solenoids now is unlikely to make any difference.
