My Vauxhall Signum has a cylinder one misfire and so far I have replaced the coils and the MAF metre, had a compression test on all the cylinders and it came back all okay. I have looked for air leaks etc but all to no avail. It`s only on tick over but it`s not apparent when driving. Can anyone point me in the right direction? (06 plate)

Can anyone advise why the boot on my Vauxhall Signum will not open? The central locking is working okay and I have tried pressing the button inside to open the boot but it just bleeps. When the ignition is on and the driver`s door is open the dashboard shows that the boot is open, but when you shut the driver`s door it disappears from the dashboard. Does anyone have any suggestions? Thanks.

I would like to know where the engine oil filter of my Vauxhall Signum is located? Are there engine bay diagrams or photos that identify the various components?

Hi. I bought a Vauxhall Signum recently. The gear lever jumps around in 3rd and 5th when you apply different pressures on the pedal. It doesn’t have any effect on the drive or the car in any way - is this normal for a 6 speed vauxhall?

Answers

Either you keep holding the gear handle with your hand when it is on 3rd or 5th, or you repair the gearbox, because you have a defect gearbox - Choukri Kayal from France

I have got a flashing light on the dash which I have been told is the headlight angle sensor. The lights do not move with steering, just when turned on. Anyone know how to get this fixed and what it might cost me??? Thanks. (1.9 cdti)

I have a misfire on cylinder one. and the diag report has come up with some faults. 1) code P0301 cylinder misfire 2) P0110 intake air temperature sensor circuit =l ow input and intake air temp sensor circuit high input. I have had it serviced about 3 weeks ago and they changed the plugs etc and I have replaced the coils. But still have this misfire? A local garage suggests I change the air flow meter but when I disconnect the sensor to try it the misfire is still present... Any ideas? Or do I replace the air flow meter anyway? Kind regards.

The spanner came up on the dashboard of my Vauxhall Signum whilst I was driving. I lost power for a second or two and then it disappeared and I got power again. I’m not 100% if it was just a spanner on its own or whether there was a car around the outside of the spanner. Could this be 2 different issues and what is the best thing I can do or get done to find out and resolve this please? (2.2 dti elite automatic)
