Number on it PA66GF30 doesn't bring up similar on Google or ebay, part number would be handy,thanks

I believe that's a heater - don't have a part number, but this might be it: https://www.ebay.co.uk/itm/385179148352

Also only just noticed after months that further up that pipe is a sensor with no plug in it, any thoughts anyone!

That has sensor in diagram ,but that is ad for the pipe alone I believe.

Believe having google that one with no connector is pcv valve, still none the wiser on one nearest maff

If you look at the e-bay link I sent you can see the connector on the line. PSA take the mick with prices, but even they would baulk at >£100 for a short rubber pipe!

What fault are you trying to fix?

[vincentfishing]

Have previously posted that I have esp/asr fault c1391 torque fault with no other faults on normal driving ,BUT, when I do a diagbox airflow test ,engine running but car static ,it throws up cold air flow above reference value( with diagbox running engine at different revs,) I can't duplicate these faults on live data revving engine myself ,the ref value and air flow match each other, This random diagbox induced fault is the only thing that I can think is causing the permanent c1391 fault ,I have replaced ,maff,egr valve ,map, yaw sensor,abs ecu, so the sensor I asked about is directly linked to air intake and wanted to rule it out, everything else on car had been calibrated/ changed or not showing any faults, down a bit of a rabbit hole at moment
