Hi,
I recently purchased a Grande Punto 1.9 diesel sporting, but I have been having trouble with the EGR valve. The first night I had it, I did a diagnostic check on it and it came up with a faulty EGR. I removed the EGR valve and cleaned all the soot out. I then reassembled the EGR and reattached the electrics. The engine light stayed off for about 3 miles then came back on again, and the diagnostics showed an EGR fault again.
After this, I replaced the EGR with a genuine Pierburg valve and ran it. I experienced hesitation at 2000-3000 rpm, but the engine management light stayed off. I then replaced the new EGR with the old one, as it didn't hesitate. I sent the new EGR valve back, thinking it could have been faulty.
I had read on the forum that some owners blanked the EGR off completely which seemed to cure it. I tried this and it worked for about 40 miles and the light came back on. This then prompted me to order another new genuine Pierburg EGR. Instead of actually fitting the valve, I connected the EGR electronically and cable tied it to a bracket behind the engine.
With the my dual EGR valve setup, I ran it again. The light stayed off for another 5 miles, then appeared again, and indeed, the fault code on the diagnostics said EGR valve fault. After this frustration, I removed both EGRs and dismantled the old one further. It turned out that the old one wasn't opening at all.
Could there be something else wrong? ECU maybe? Or was it just coincidence that I purchased 2 faulty EGRs?
Many thanks,
Matt
