#1: knocking tapping noise Author: hampshire1, Location: southamptonPosted: Mon May 02, 2011 4:08 pm ---- 206 1.4 hdi 2003. oil fine. knocking or tapping loudly on tick over 800 rpm
from cam belt side of engine. at 1000 + rpm the noise goes, the car runs really good. just noisey on tickover. normal fuel consumption. 100,000 miles on clock. any ideas? cam belt change due to be booked in will this help?
#2: Re: knocking tapping noise Author: Antknee, Location: ManchesterPosted: Mon May 02, 2011 4:19 pm ---- Does it sound louder than normal when its idling?
If so... oh dear, mine did this 2 weeks ago and it was the timing belt tensioner had exploded and the bottom pulley had just about gone too
Same car too and same year
Edit: also it was booked in for a timing belt change the following week and was on 106k

sometime poor oil quality will give you tapping noise.
#4: Re: knocking tapping noise Author: hampshire1, Location: southamptonPosted: Mon May 02, 2011 4:31 pm ---- not sure what oil, not expensive though. maybe oil and filter change will sort it out..
#5: Re: knocking tapping noise Author: hampshire1, Location: southamptonPosted: Mon May 02, 2011 4:32 pm ---- what oil and grade would be best for it?
#6: Re: knocking tapping noise Author: hampshire1, Location: southamptonPosted: Mon May 02, 2011 4:35 pm ---- the noise sounds like its coming from top of engine and goes over 1000 rpm.
