I'm probably being overly cautious here but my 2017 A4 is approaching 100,000 kilometers and while it still drives perfectly fine, I've got this nagging feeling that I should be proactive about the gearbox rather than waiting for symptoms to appear. A colleague of mine with a similar car just had his transmission go completely without any warning at all, one minute he was cruising on the highway and the next thing the car went into limp mode and that was that, eight thousand dirhams later. I asked my usual garage about doing a preventive diagnostic check on the transmission and they said they can scan for fault codes and check the adaptation values but that might not catch everything, some failures happen mechanically without the computer noticing anything wrong. I've been reading up on what exactly the TCU monitors and found
www.auditransmissionrepair.ae which had some interesting info about how clutch wear can sometimes be spotted early by looking at the adaptation limits before they throw an actual fault code. I'm tempted to book it in somewhere just for the peace of mind even if it costs a few hundred dirhams, but I'm wondering if these scans actually catch anything useful or if it's just a way for garages to charge you for plugging in a laptop and telling you everything looks fine. Anyone had a diagnostic catch an issue before it became a roadside emergency?
