Scoda Octavia 1.8T 4x4 Estate. 2001 Model. 121,000miles.

Car has recently developed a knocking sound at the front end right hand side, which gets worse going around R/H corners. Stops when clutch depressed and still moving? Noise feels like drive related as it does ease when you accelerate and get worse when you take foot of the gas. Another point to note is that it is intermittent, being there most of the time but occasionally disappearing for a few miles completely?

Engine management light came on today although I don't know if this is just a co-incidence. Engine did feel a bit lumpy earlier (vibration), but is now back to running smooth as ever?

Thought it was Anti roll bar bushes which have been replaced to no avail. - On a sepearte note, does anyone know if you should be able to move he anti-roll bar laterally by hand?

Can't see anything obvious. Problem has got me confused and any advise would be appreciated.

Thanks

Craig

anti roll bar shouldn't move(not by hand anyway)that much iirc,but the links on each end do,but not loosely,they should be firm and controlled movement,not slack.

when mine went on my vrs it sounded like the exhaust knocking around the downpipe area,new arb link both times cured it.

lumpy running and engine light sounds like a coil pack is about to expire

Agreed, with the note that a dodgy ARB drop link isn't always audible. DAMHIKT.

Thanks for the suggestions. Replaced front ARB and bushes a week ago and thought the problem was resolved. Sadly it returned today with no perceivable differences and still intermittent!

Car back on the ramps and checked, with nothing obvious. ARB links look good, no play in CV joints or drive shaft, wheels OK, suspecnsion appears OK.

Going back to my earlier description, the one thing I cannot work out is why the knock is intermittent? What could do this?

I have also been thinking about why it dissapears when I depress clutch and returns when clutch released. Gets bad on RH lock? Could this be the Clutch release bearing? Has anyone had any problems with this or any thoughts on if this could be the problem?

I am guessing I will just have to wait for the fault to be 100% persistant before I can investigate fully, but would appreciate any help or thoughts.

i think it might be a gearbox/drivetrain issue then, possibly the diffeential is knackered

I've now got a nasty feeling that either Tom's right, or it's an inner CV joint failing.
