I am running a decent mobil 10w40 though, so a little thicker when cold than the normal stuff the dealer uses, that may help.

For ref, my car has had recent coil packs, MAF, CPS etc, I compression tested after servicing last month while having the plugs out and replacing spark plug tubes - all was good, and it shows no faults, codes or any signs of poor running, yet you can feel it at idle - I'm not worried about it at all.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Rob
lol diesel you know what i mean !! cheers rob ill give that a go next change over , any answers why its a bit lumpy on tick over tho it has just had new plugs and coil packs as well
Mines a little lumpy on tickover, when I say lumpy, I don't mean missfire or nasty violent vibration, the exhaust note is also fine and the revs are constant, but, you can 'feel' it ticking over if you stop and think about it (otherwise you wouldn't notice).
I've had many many cars, with high and low milage with varying size engines, and tbh, most cars if you actually stop and feel for it will shudder a little at times if left idling. Unless you have any popping out of the exhaust or you can feel it shaking considerably or missing then I wouldn't worry about it.
For ref, my car has had recent coil packs, MAF, CPS etc, I compression tested after servicing last month while having the plugs out and replacing spark plug tubes - all was good, and it shows no faults, codes or any signs of poor running, yet you can feel it at idle - I'm not worried about it at all.
Cheers,
Oh, it doesn't tap when starting either, regardless of if I leave it for a few hours, days or weeks and then restart.
I have heard however that it is common for them to tap and even smoke a little on startup if left sat for a bit.
I am running a decent mobil 10w40 though, so a little thicker when cold than the normal stuff the dealer uses, that may help.
Cheers,
My old Carrera had a slightly lumpy tickover in that you will notice the passenger seat vibrate a little. This was worse if you turn off the aircon. It is a common feature assuming that everything else is right. It is never as smooth as a straight six. Also there was a very light tapping when the engine was warm but it disappeared immediately when revved slightly. My engine had 75k miles but regularly serviced with new lambda sensors and MAF.
