Vauxhall Zafira Emission control light

MartinS

These cars are useless, we have had ours 3 weeks had the AA twice and its still sat on the drive useless.

So far, throttle body removed and deep cleaned,
EGR removed cleaned, New plugs, New coil Pack, New exhaust manifold , lambda sensor , cat and exhaust, new fuel filter, idle air control valve, pump relay, thermostat and housing,

Guess what car doesnt even start now, im going to have to call AA yet again and get it towed into a garage,

7 years, one thermostat, one crank sensor, one back box. Loaded like a white van. Indestructable in my case.

The Exhaust emission light and the Traction control system /Electronic stability light are on permanantly. Symtoms are car lost power on motorway and sounds like not firing on all cylinders.Diagnosed by a mechanic using a machine

exhaust gad recirculation - the egr valve will need a good clean.

Those are Snap on codes, not Obdii compliant codes, he needs to learn how to use the machine correctly.

got the code by doing pedal test has i have not got a diagnostics computer
the car drives fine sometimes the car revs a little like the automatic choke has come on but only when first started and run for a while but other than that it runs ok seems smooth and doesn`t sound rough just been on holiday in it and done about 130 miles with the light on came on half way there
