I bought this controller to try and get OPS (Optical parking Sensors - display of car on the head unit) on the TT, it turned out that it was not compatible with the RNS-E that the car has fitted (it worked but would not give OPS)

So ideal for anyone wanting to upgrade there non OPS controller to give OPS, this is for just rear sensors.

Looking to get some of what I paid back for it

£40 posted within the UK.

should it not be an 8k controller for front and rear?

Correct. 4K for rear only. 8K for front and rear.

Sorry posted without thinking!

Yes it is for rears only (that is all the TT has)

Do you still have this controller? Will this show OPS on my Bolero unit I have just fitted in?

Never used a Bolero before, but if it is capable of showing OPS then yes it should be fine.

What's the Audi part number for this? I need to investigate this a bit.

Pretty sure there is no Audi part number, (just the Skoda one in the thread title) but I will check at the weekend when I get home.

For those that want to add OPS to retrofit OPS I can make the looms

 

Sensors can be found on ebay for around £10 each

 

OPS does display with Bolero

Still have this
