Thanks for your help, but acctuator was moving just not enough and not always.

Turns out the waste gate acctuator was sticking sorted now. Strange how you get a couple of electronic issues and you forget the problem could be mechanical.

If the MAF was disconnected i.e. ECU seeing 0 air flow, would this cause overboosting/kangarooing?

Only fault code 3014 air flow low fault

This wiring mod https://www.landyzone.co.uk/land-rover/td5-maf.255153/ connects pin 11 on red plug to pin 12 on black one, but it was doing it before this mod. Sorry don't have a Nanocom only Hawkeye.

Will make sure, but blew through all the small hoses and connectors with compressor.

Wastegate is working ok, also tested it with compressor. MAF sensor is disconnected and wiring mod done. Will check ambient pressure reading tonight but went for a test run last night with MAF removed (in case there was a restriction in the airbox) and still kangarooed.

Yes all pipes ok.

New modulator installed still missing. All pipes ok. Connected pipe from turbo outlet to acctuator, still missing. Only fault code 3014 air flow low fault. Boost pressure still showing as dropping back to 100 for an instant then back to normal. Is there a way of testing the map sensor and wiring?

Fuse 2 ok have ordered a new wastegate modulator.

So engine was running fine but now is kangarooing/missing under acceleration over 3k revs. The live data in Hawkeye has the MAP reading climbing with acceleration then suddenly drops to 100 engine misses for a second and then back to normal pressure and then repeats. Is this a broken MAP sensor??

New BCU fitted and programmed all working as it should :) If anyone needs a working IDM I have a working spare.

So swapped the IDM still got wipers going and no front electric Windows :( What is the procedure for changing the BCU?

Thanks, was thinking the same.

If I unplug the connector from the stalk the wipers stop at the parked position but I can still here the relay clicking, the delay selector still works until I unplug the small connector on the top of the steering column ten it goes to max length between wipes. Checked and cleaned earths at...

Will check the earths. The battery was completely disconnected when I was welding but not BCU. Car started and everything worked as is should after I had finished welding. Is there any way of switching off intermittent wipe by removing fuse or cutting a wire as could live without it as a last...

So have taken IDM and BCU out and both look as good as new with no bad connections or any sign of water. The only way I can get the rear wiper to stop is to pull the fuse and pull the multi plug out of the stalk to get the front ones to stop their intermittent sweep but I can still hear the...

Just to clarify front wiper are on intermittent all the time and dock in the correct position and back wiper is on all the time, both switches are in the off position. :(

Managed to lever the top of the drivers door open enough to get a long bit of fence wire in hook the key in the ignition and put them out. Car is now unlocked and central locking is behaving. Anyone know why the wipers wont switch off???

I took my Disco of the road at the end of last year as it failed its MOT with a rusty rear end. I replaced the back 1/4 of the chassis with a new section last month. I went to start it tonight to get it ready for its MOT but the battery was completely dead so stuck it on charge for and hour and...
