No power on my Volvo V40 on LPG and Gas

From a point at sea, to the circles of your mind, this is Willem Lochtenberg:

Does this only happen on LPG? Is it running OK on petrol/gasoline?

What sort of LPG system is fitted?

Hi Stewart,

its happen both on gas and lpg. The lpg system is a G3 system with no loss of power (!!?!!). I spoke to a mechanic at the Volvo dealer. He told me that there was nothing wrong.....

This implies that it's not related to the LPG installation. In fact it also implies that it's not related to either fueling system.

This really only leaves valves and valve timing, or the ignition system. Unfortunately I have no experience of the V40, so can't comment further.

Others on here may be able to help you further.

Is there power in lower gears? Are there any error codes on the electronic control units....sounds like it may be in some sort of 'limp home' mode. Does the engine management light turn on with the ignition and then extinguish after starting the car? Perhaps there's a major mechanical fault like loss of compression....but I think you need to let the mechanic have a tinker.

Hi Conrad,

It seems to me that there is enough power in the lower gears. In 4th en 5th gear there is less power available. No control- or warning lights blinking....

Stewards suggestion that the ignition is the cause of the power loss seems to me more likely.

Thanks!

regards,

Willem
