Was the code triggered near the end of this log? Both LP and HPFP look a bit ragged at times. It dropped bigtime during the last part of the log when you stepped on it in 2nd.

Edit: looked more closely at the log file and you triggered a safety for low fuel pressure (high). LPFP dropped a lot too, but probably not enough to starve HP, so might be a HPFP issue.

Yes it was the second time I did a wot run in that log that it triggered the 29DC code so you reckon both are not optimal? Terry told me hpfp but as itís a big expensive job and time consuming to do I just wanted a second opinion even though I thrust him implicitly

Thank you for your input

Do you think any of this could be simply caused by the fuel pressure regulator in the tank failing and being unable to maintain a decent pressure?

How many miles on car?

Hpfp isn’t a huge job, but I beleive a new hpfp is relatively expensive new.
