Vauxhall vectra sri 2,2 04 - warning light on dash - Bosh
I have the engine electrics/transmission electrics light on my dash every time I start my car, which puts it in to limp mode. If I turn the ignition off and then on again it clears and the car drives Ok....ish. It can be a little sluggish in low gears. This has been going on for so long now it is driving me mad. Once the petrol in the car gets to around 30 miles left the light stops coming on, however as soon as I fill up again the light starts coming on again. I have had the car put on diagnostics and it comes up with throttle body, however the mechanic cleaned this up and it has made no difference. I have had the fuel pump changed and a new coil pack fitted. No difference. It's supposedly had a full service, however, I was told that the fuel filter wasn't changed by another mechanic so I suppose it's quite possible that other things weren't done either. I do a lot of short journeys and have been told it could be the head gasket, not really convinced by that. When I take the car on longer journeys the exhaust emission light comes on which again makes the car lose power. I would really appreciate any input.

Sorry, as you can tell I'm not mechanically minded. The engine code is Z 22 SE

Not much to go on here,but the fact that fuel level seems to be an issue,i wonder if there is a problem in the fuel tank?Does the engine rattle from cold start,as these suffer timing chain problems.

No the engine doesn't rattle from a cold start. I have found the codes that came up when it was put on the diagnostics if that helps. They were: P1191- fuel rail pressure sensor circuit range/ performance/ high input/ low input/ or fuel pressure system malfunction.
P0302: cylinder 2 misfire detected.
P1500: throttle control motor malfunction.
P1550: electronic throttle control reduced/ forced idle/power management/ engine stop.
Since then I had the fuel rail pressure tested that was normal. And as in original post had the fuel pump changed and the coil pack changed also had a full service, and the throttle body motor checked and cleaned.

Ok, scrap that, still no closer to finding out what it may be. I was told it might get be the lambda sensor as it came up as a code but that was cleared and didn't come back up, the light is still on. I've been told whoever did my service didn't do the job properly at all, we know for sure the fuel filter and air filter weren't done at all. Possibles are now that it could be a clogged exhaust and/or the filler cap isn't the right one for the car and doesn't create a tight enough seal. So I have a new locking filler cap on order and will have to get the exhaust looked at. Any other advice would be massively appreciated feels like I'm just throwing money at it.
