Thread: Is 0.58 bar turbo pressure at 3000rpm about right for a Td5?

It's not a big problem as it's occasional and minor but it's a bit bizarre. The inability to rev out is a bigger concern, but even with that, the car runs great with the Storm Tuning map up to 2500rpm...very smooth and torquey, great economy and I can't get it to blow smoke even if I try.

I've attached another Nanocom log if that helps anyone with diagnosis...

Thanks

I know you said you changed the wastegate modulator, but the problem sounds exactly like a modulator issue. Was the replacement new?(this is KAOS here, and we don't assume! ).
To be sure, to be sure ... I would suggest you at least try a modulator bypass, just to see if it will give you more than 3K revs.
it may do so once maybe twice, then overboost and reduced power again, but turning motor off and back on again I think resets it you you may get another test shot to see if you get better boost AND >3K RPM.

Another thing I was thinking about is that when you did replace modulator, you connected the correct hoses to the correct ports too?(see the previous KAOS comment re assumptions).
Assuming that all was done correctly too, have you checked the hoses to and from the WGM for leaks too?
( I did read the whole thread again, and you said you checked silicon hoses, etc, etc. .. but not specifically the WGM hoses. )

If you can't rev it above 3000 rpm it's possible that the pump is working only on LP, here's an easy trick which can rule it out Disco 2 - Check Td5 fuel pump HP | LandyZone - Land Rover Forum
