So looks like I've just wasted 200 in buying an egr valve on the instructions of the diagnostic specialist to find my issue has not been sorted. So on all the forums I've ever been on, I find this forum the most helpful. Therefore could someone help me in diagnosing the following codes please p0401 and p2598? The car is a diesel vauxhall astra. Where should I start and what should. I look at/test?
