TD5 Power Loss
drum:
Thanks lofty, but I don't think it's that, it more like a rev-limiter been hit.
I've just order a OBD reader thing for my PocketPC lets see what that tells me.

This won't happen unless the boost pressure is above approx. 1.5 or 1.6 bar at ambient (21 - 23psi) ... as this is the boost limit for a Td5.

Just adjusted the linkage on waste gate, so it cut in earlier, and all was ok.

So have you lengthend the rod and reduced the boost pressure, or shortened it and increased it??? The actuator does not effect when the turbo cuts in, just the pressure it is allowed to produce before the waste gate is allowed to open.
On a Defender anyway.... a Disco is slightly different.

--- Quote from: "drum" ---I looked at Rovacom Lite a few months back, but you're really looking a spending 1k+ to get a decent setup. Stuff I'm thinking about are basic fault reader plug into a PocketPC, and allow you to reset faults, and read error codes. Anybody any experience of them??

Rovacom lite is only about £500 for just the Td5 sections.... plus the cost of the laptop.
drum:
Think I might have included the price of a Laptop in the cost, still rather alot of money. I'm going to try a simple code reader for starters. I already have the pcoket pc for sat-nav so we'll se how we go with that.

Are you getting excessive smoke when the engine goes flat???
Or any diesel 'knock' noise??
