Call back from Cupra customer care today - they basically reiterated what the garage had told me - faults log was reset and no new fault codes resurfaced after numerous stop/starts and 50 or so miles driven so they have nothing to go on.
I tried my best to politely point out that they clearly DO have diagnostic information from the previous two failures and that should be enough for them to derive some sort of technical solution. Besides that, the fault originally took 1100 miles/3 weeks to surface, and then again within 20 miles/1day of receiving the car back from SMC - so there’s absolutely no telling when it will rear its ugly head again!
Made it clear that it’s one thing for garage technicians to come to this conclusion, but not for SEATs supposedly “technical” team to suggest the equivalent of “try turn it off and on again” - any average Joe tries this as a first attempt, this is in no way a reasonable technical response!
They will get back in touch with SMC today (they’re going to try more things to make it fail - I reserve no hope for that), then call me back tomorrow, but they made it clear that the courtesy car expires tomorrow unless the garage extends it. The problem I see here is that SMC don’t want a car sitting in their possession that does not fail, and that they are not sanctioned by SEAT to attempt a repair, and therefore make a warranty claim, on (e.g. replace the BCM/Gateway module).
I will be trying hard to escalate this within SEAT/Cupra to get their technical team properly involved (or higher up to an engineer actually worth their salt who cares enough about their job to investigate)!
