2005 Vauxhall Signum Problem
|Car||Vauxhall Signum 2.2 direct petrol|
Hi there new to the site bought a signum 2005 2.2 direct nothing but problems
The car broke down would not rev up and was in limp mode aa came out and blanked of egr valve that seem to help but not much
the car will rev upto 5000 rpm then start miss firing turn on off to stop miss fire and also drives like a 1ltr
Took car into vauxhall and they said compression good fuel pressure good but lots of fault now the whole time this was there the egr valve he kept blanked off codes which were
p0400-62 egr valve malfunction
p1405-06 egr circuit low voltage
p1403-08 egr circuit malfunction
p0105-06 manifold absolute pressure sensor circuit open - low voltage
p1112-03 swirl actuator malfunction
p0100-06air mass flow circuit low input
p0110-14 intake air tempsensor circuit high input
p0191 - 02 fuel pressure actuator voltage
And when you rev passed 5000rpm it comes up with miss fire codes but they go when you turn car on and off
The car has had new fuel filter full service and secound hand maf sensor from scrap yard
vauxhall have come back to me and said that the wiring harness is not in the best condition but ok so to get a real diagnostics to have new one fitted at £800
the car does drive whilst egr valve blocked off but not like a 2.2 more like 1.2 but as soon as you rev passed 5000 rpm all lights come on
also when you un blank egr valve car does not drive at all
what im trying to ask to anyone that can help could bad egr valve or map sensor cause this or do we believe the harness needs replacing or do i scrap the car lol sorry this is so long and hope this is on the right topic many thanks stuart
