Sorry to bump this, got my speedo in bits and the dials not lighting up bright enough. I've used the same smds but white (side mounted) and its not worked very well, light very dim. What kind of bulb did you use for your dials!?
Ok all of these problems where caused by a loose earth strap on the ecu.
Unbelievable that it would let the car seemingly run fine but then cause l these little problems but tightened the strap and it's all gravy!
I'm after nicer looking caps for the power steering and brake fluid bottles.
I already have an Audi r8 oil cap and a golf2 gti washer bottle cap.
Looking for Somthing that's either black or shiny ideally, any ideas / links??!
Still not had the light flash or the judder again but still can't connect to ecu, apparently the code I have from vagcom is showing that there is a fault somwhere that is blocking the ecu. No more info can be pulled!
