Hi guys, my 2002 td5 has had some issues since purchasing. I think the oil cooler orings failed (repaired) which led to water pump failure (repaired) and PAS pump failure (repaired) but because it probably overheated the head maybe warped. I have had it skimmed and refitted by an independent garage but it now has a noise similar to a noisy tappet and is hugely down on power. It had more with a warped head. I am hoping it is only that the injectors need coding, can anyone confirm this needs to be done after removal? Also is there anyone in the north east with Hawkeye or Nanocom that can carry this out? Thank you in advance for your help
