Hi there, I had a remote roof module fitted in my A4 about six years ago and it worked fine. Recently it started playing up - specifically it wouldn't open the hood remotely. I thought six years was fair for a cheapish after-market gadget, so ordered another one to replace it - this one: https://www.ebay.co.uk/itm/143424315368 I removed the door card to fit it and, since it was similar in appearance to the defective unit, and had identically coloured wires, I just cut the old unit off and, using crimp connectors, joined like to like. Before I put the door card back on, I tested it. Nothing - not a sausage.🤦‍♂️ I put the car away for the night, having also discovered that I had bought the wrong size door card clips. 🤨 The following morning, I came out to the garage with a mate of mine to explain the snag. Before we took anything apart, I tried the unit again (you press 'lock' three times within five seconds to raise the roof; 'unlock' three times within five seconds to lower it) - bingo - it worked perfectly 😃👍 My mate (an RAF Techie on the F35 LIghtning) just said "Ferking canbus - there's no understanding it" 😆 He reckoned the canbus does a system check during down time and finds and adopts new stuff. This might not be accurate, but certainly follows the early snags I had with the original module, which was a nightmare for 24hrs - and then worked perfectly... 🤔 Fast-forward two weeks and it has become unreliable. Normally when you press the remote for the third time you'll get a 'click-click' noise from the car, and then it'll enter its routine. Today I've been unable to raise or lower the roof remotely (although the button on the centre console still operates normally, as does holding the key in the locked or unlocked position in the driver's door to raise or lower the roof). Anybody have any ideas on what might be causing this, or how to persuade it back to normal operation please? I'm going to drop the vendor a line with a link to this post, although my feeling is that it's not a fault in the module - more likely another canbus interface thing. I recognise that this is likely the ultimate first world problem 😆 but any advice/experience would be appreciated. Thanks, Mike 😎
