I'm hoping someone may be able to point me in the right direction here.

Basically ive bought myself another range rover needing 2 turbos.
I've changed the turbos, cleaned all the pipework, intercooler and sensors.

Now I have a couple of faults showing and the car is sluggish but still drives ok

When plugged in also the MAF readings for both banks are slightly out and one actuator is showing 10% the other 100% but there both free and both cycle fully

Any help would be great

Regards

Sorry 2009 tdv8

Are the TDV8 actuators vacuum activated? 2019 5.0 SC SVA (Current)
2012 5.0 SC AB. Sadly written off by a campervan
23 plate Focus ST (Current)
1942 VEP Ford GPW Jeep (Willys) (Current)
1943 Whites M16 Halftrack (Current)
16 plate Eurofighter Typhoon, 2 x Eurojet engines with 20,000lbs thrust each. 1380mph

No there electronic, both moving aswell

Any chance they need some form of calibration?

New, recon or 2nd hand?

Recon units

For this very reason, I only fit brand new units

The actuators are very, very sensitive to their mounting positions, and calibration can only be carried out 2 places in the world, AIUI

That said, wiring checks first. If they check out fine, then its Turbo back off I'm afraid

Thanks for that buddy, any particular places worth checking first? Or is it just a matter of going through all?

I bought it with faulty turbos also so I don't even know if the fault was there before hand 😂.

1 injector was slightly low so swapped that out and now all 8 are just either side of 1000.

I've had it on the iid tool today actuators seem to work correctly as does everything else, map seems to fluctuate very slightly on the graph MAF readings are slightly out from each other but both seem to act similar as it's revved.

Keep getting random p132e code now but not very often mostly just error message on dash but regardless the car just seems to fly just an odd stutter as it comes into boost sometimes.

I'm goner let a friend have a look next week I think as I havent really had time to do anything myself as I'm still working everyday.

Thanks for the input

Live values should be between 5-95%

If that's reading correctly, between commanded and actual values, next step is a smoke test

I was thinking of building a smoke tester if I get chance, I think off top of my head they went from 10%-95% but opposite each other when turning ignition off/on
Left would be 10 right 95 then swap

Should both be identical...

Oh that's strange then
I'll have a look

Well thought I'd update just for anyone who may have similar issues

First thing I thought was that I'd put the actuator on the wrong way on the passenger turbo. So I moved it do the rid was the other way, still had problems.
I plugged it in and got all the following problems changed injector etc.

Still scratching my head, I decided I'd put the actuator rod back the way it was initially and hey presto it's been fine, 🤦

Oh well all sorted now time to do bushes tyres and tracking
