On starting the engine revs at 900 but as you drive away slowly you get a kick in your back and the revs will not go below 1000 unless you switch off and start again.Same problem when moving off. This is an intermittent problem which started 2 months ago. This makes driving in icy conditions dangerous because when changing down the gears instead of using the brakes the car takes off at 1000 revs.Town driving in slow moving traffic is also a nightmare. Spend most of the time dipping the clutch or braking. I've written to Vauxhall and i'm awaiting a reply. Local Vauxhall dealer has bent over backwards to fix this but to no avail. Any solution please .

mate i am sorry to say from my point the the clutch is faulty. need to replace it for a new one. your car should still be under warranty which means that the dealers should change within the warranty.

Dont see how the clutch has anything to do with this problem. Even idles at 1000 revs when in neutral gear

Like you I would discount clutch theory .Can't suggest anything that the dealer wouldn't have already tried . Would be interested in outcome and what Vauxhall come up with .

Dont have solution but if it makes u feel better (it does for me) have same problem! did it from delivery on xmas eve & agree dodgy in snow/ice.
More recently it now has another symptom that maybe related? sometimes on start up when warm say after 1 or 2 hours off it sounds like its running on 3 cylinders & hunts badly at idle so rev counter bounces around.
No sign of any ecu warning lights & to be honest both problems are intermittant but you can provoke revs sticking on by letting engine work hard at low revs. Been back to dealer 3 times with no joy am loosing patience.

Vauxhall says to take my insignia back to the dealer AGAIN but i feel that it is a waste of time because it performs fine when within sight of the garage GRRRRRR!!!!!!!!! I'm wondering if it has anything to do with the cold weather . Has run like a dream these last 2 days.

Hi there Mark 130. I got it from a good source that if the battery needs a bit of a boost the engine revs increase automatically. I didnt believe this at first but now that i am doing more driving in daylight hours it seems to be the case. My Insignia seems to be behaving itself lately. Maybe just a coincidence but annoying as previously stated.My son and brother havent had this problem with their Insignias.

Vx Info:

Insignia 2009-Onwards – Engines A20DT/C/H/J/L/R
Increased idle speed

Customer complains of an increased idle speed up to 1150 rpm.
Increased idle speed signal is managed by the engine ECU but based on a signal coming from the BCM
(Body Control Module).
If the state of charge (SOC) for the battery is too low the BCM urges the engine ECU to increase idle
speed in order reload the battery in a proper way. There are three possible idle speed steps going from:
-- step 1 (= 925 rpm) to
-- step 2 (= 1000 rpm-1050 rpm) and
-- step 3 (= 1100 rpm-1150 rpm)
The step is dependent on the SOC as well as the outside temperature, which also affects the SOC.
Other possible reasons for increased idle speed also managed by the engine ECU based on a BCM
request:
a.) During auxiliary heater on the idle speed will be set to step 2.
b.) During HVAC operation the idle speed will be set to step1-3 based on the thermal load.
c.) During DPF regeneration mode the idle speed will be set to step1-3 based on the engine
requirements.
In case of customer complaint please explain this technical content to the customer.
