can anyone shed some light on what might be the issue with my 2.4 tdci Defender ? Symptoms are surging acceleration between 2000 and 3000rpm. I have had the Vcv changed and still does it. I had an error code of P0404, egr issue, cleared it and that has not come back, but still this even...

Thanks I am new to this forum and trying to find my way around! The surging is uneven acceleration when the throttle is between the 1/4 and half way point. So it appears to hold back then power returns and so on

Gents thanks for taking the time to reply, the symptoms I have described do you have an idea what the issue could be? I have cleaned the turbo twice with revive. What else could cause this?

Hi, can anyone help me, I have surging between 2000rpm and 3000rpm. Would. Remap help?
