Hello, I'm from Belgium and since a few weeks I'm the happy owner of a 2010 Seat Ibiza FR BocaNegra ( yes, that combination is possible over here).
Last week I had it tuned by a very well-known and reputable company. The day after the remap the EPC light came on. Assuming it had something to do with the tuning I called the company, who were very helpful and asked to take the car back to them so they could have a look. The fault code they read was 17978: engine start blocked by immobilizer (no other codes). They have since then tried everything (remap with a newer version, looking for checksum errors, revert back to orignal map,...), but to no avail. I must add the car drives perfectly and starts first turn of the key every time, but EPC light and code reappear within the first mile after being cleared.
I don't want to attack the tuning company, as they have been extremely helpful about this and have spent hours trying to find a solution; neither do I want to claim warranty from the dealer (I know a remap invalidates drivetrain warranty and I'm an honest guy, so not going to lie; they could probably tell anyway).
Any ideas what could be the problem? With that code, the car shouldn't start, should it? Is it a result of the remap, or just a funny coincidence?

Little question on the side: the car now delivers 198 hp and 314 Nm of torque (between 2500 and 3500 rpm, after that it tails off slowly to around 280 Nm). Should I ask the tuner to limit that torque (to under 300Nm) to protect the DSG, or will it cope? They say it's ok, but I want to be sure...

Greets,

I would say it's possibly a key issue, we see this fault sometimes at work (Audi). Really it needs a full guided fault finding to narrow down issue. There could also be a problem in gateway control unit but again would only be found with guided fault finding.

The DSG gearbox can safely handle 350Nm of torque so you will be fine on that front.

Also the remap would invalidate drivetrain warranty, however if the fault is not related to the remap it would still be covered. They can tell if it has had a remap but only if they go looking for it. It's best to be honest though as if they decide to do any software updates it could possibly erase the remap.
