Engine Power Reduced

Post by adz1991 » Fri Jun 14, 2019 7:17 pm

Hi all,

I have an issue with ‘16 plate Astra, 1.0l Petrol Turbo engine. I have seen a similar topic on here but it was related to a Diesel engine.

Recently my Astra when in 4th/5th gear and accelerating shows a message on the dash ‘Engine Power Reduced, and the car slows.

Took it into Lookers as it is under warranty and they have said it is a slipped clutch, which is not covered and will cost £1400 to fix. Any advice from other owners who many have had a similar issue would be great. The car has done 34,000 miles. Just seems insane for the clutch to have gone!

The "Engine Power Reduced" message is supposed to be the new equivalent of the old "spanner light" If I'm not mistaken as it sounds like limp home mode. That points more to an engine management issue rather than clutch. Things like a sensor reading out of spec, or failed completely, etc.

But then again I don't have access to service docs so I may be wrong. Are there any fault codes stored? Did they even do a diagnostic? The "Service Vehicle Soon" message on the older Insignias was the same, I think.

cant believe a clutch would fail on a car that has only done 34k, i would get a second opinion mate and if it is then i would contact vx direct and complain

It will be covered if it is down to oil or brake fluid contamination of the friction plate due to failed seals. If it is worn friction plate then it won't be.
Vx will want you to sign a disclaimer before they start any work stating you will pay should it not be covered by warranty.

Have you checked the egr valve? It might be sticking open at times.

I had a problem with my 67 plate diesel yesterday. I was accelerating after leaving a roundabout and the car just died. It didn't stall but there was no response to the accelerator despite the engine still running. Having pulled over I switched off the engine and then restarted and it was fine. Another thing which I'm wondering if it may be linked is that the message ESP Service Soon came on a week or so ago but went off after I later stopped the car and did not reappear after restarting. I've recently had a recall for the clutch and brakes completed. The dealer was initially reluctant to have it looked at as they said that as the fault has gone they may not be able to find it and to come back if it reoccurs. I was not happy though so called them and insisted they look at it Car's going in tomorrow for this. In the meantime I'm looking for as much evidence as to what it might be as I'm anticipating a poor outcome.
