This won't help you much Shaun, but while the fault is now on this forum - We see a lot of these polo based models sporadically flashing steering warning lights. When read for DTC's there are none logged.

The fluid level is always just below minimum on the ones we have seen - the level rarely gets checked & it does drop in normal use, the diesel is never checked due to having to remove the battery to check the level.

You dont have DTC 17911 logged anywhere do you Shaun? The Alternator DF load signal wires break on these at the front of the gearbox & often log the G250 fault.

I believe these also suffer water ingress / corroded contacts in the multiplug behind the N/S/F fog lamp.
