Hi Dave.
Just realised you already had a thread going on this back in December

https://www.the75andztclub.co.uk/for...d.php?t=326436

Which most of the answers were given then, did you change the pedal out on your car ?

Been in hospital, didn't have time/signal to reply to you within seconds of your comment

Yeah, not been well lately, when I have been its been p@ssing down, I've checked the wiring to it, swapped the pedal, and fitted a new maf sensor. there's probably a faulty wire laughing at me in plain sight

If you can find a local member with a working car, swap the pedal potentiometer over, this fault is always due to the pedal pot!

Actually it is an important question for a diesel fault too - or to be more precise when the car isn't responding to the pedal do the idle revs increase or do they stay as per the usual idle engine speed?

Is there a fuse/relay I've missed (nothing on Autodata) I'm running out of ideas and patience ��

With my recent problems, when I cleaned the maf housing and replaced the MAF, I had the same symptoms. I had dislodged one of the hoses from the filtered air side of the maf.

There is no throttle plate on a diesel. I asked about it when I thought we were talking about a petrol car.

Well if the revs don't rise to around 1100 rpm with no response to the pedal then the ECM doesn't think there is a fault with the pedal assembly as that is the default position to enable you to limp home.
As mentioned best to swap the pedal assembly with a known good one and go from there.
