    Hi. Can someone advise how to get the instrument binnacle out so I can change one of the bulbs? 1993 R129.

    I came across this for the 124 but I don't suppose it is the same?

    They just push out from the rear, you can use hooks but that glass is £175

    Thanks Malcolm. No clips or bits to unhitch? Just give it a shove?

    Yes correct,, just run a flat bladed knife all around to free it off in case it stuck.

    You will have to remove the rear cover to replace the main bulbs

    If the 1.2w small tell tale lamps the the Ring RU509T will do but you have to squeeze the contacts closer together with a pair of pliers

    You will have to take the steering wheel off, push or pull the cluster of evenly. Hope this helps

    Thanks chaps. Mine has the electric steering adjust also so hopefully won't have to take the wheel off! Or put another way, I am not taking the wheel off so the duff bulb will need to stay put!!

    Hi Malcolm. Good news. Still waiting for ETA to come back from the chap in the US- he is in NY so although job done (rewired, new potentiometer) he can't post it back due to storm chaos. Will update once back but I am hoping and fairly confident it will sort the damn ASR issue which has plagued my R129!

    I watched the video on his site where he is testing your ETA :)

    Have to say he has done one thorough job on it. I'll give a full report under a proper title once it is back and installed but he has rewired it, tested the coil (which can go apparently), changed this potenitometer - then redid it as he wasn't happy with the way it was sitting. Left it running for 12 hours to make sure no overheating then plugged it into a test SL to make sure it was working A1. So, I think we can assume if the fault remains then it isn't the ETA!
