Ok peeps, I have had a pretty **** day because of the car. I have calmed down a bit, so will post the results here.
But it's not good...
This morning, Seat UK formally confirmed that the car's warranty on the ECU and Engine is void. They are not prepared to investigate the matter any further, believeing the REVO code, and that alone is the cause of the ECU's inability to communicate with the rest of the car, and VAGCOM. Furthermore, they have cancelled the breakdown assistance for the vehicle too, as it has been substantially altered outside of the original spec. They said that any further breakdown on the car is highly unlikley going to be atributed to the OE hardware in the car, and is due to the engine running outside of the recommended spec.
The vehice is under a contracted finance agreement also, and they also believe I have broken the terms of that contract, and have demanded payment in full within 28 days for the outstanding balance, or the goods returned to them in original condition (fair wear and tear excluded). I have asked for written proof of this by Friday.
They have also cancelled and taken back the hire car.
The guys at VagTech were present when this was all being discussed with the suited chap from Seat who was there this afternoon, and explained to him how none of the cars electricts ect were touched, but the person from Seat wasn't bothered. While he was there, they built a test bench with the aid of Carl from REVO to see if ECU info can be pulled up from it when it is removed from the vehicle.
As he expected, when the ECU is taken out the car, it did function correctly. This would lead to a wireing fault, but he said it's a needle in a haystack situation. And they also confirmed that no wires were touched during the IC installation. Seat still refuse to believe this.
Despite the fact that there is no longer a warrenty on this 9 month old car, Seat have instructed VagTech to stop carrying out work on the ECU, as it's their property! A few choice words from myself and the guys at VagTech were exchanged, then the Seat person left.
The instruction was then given to strip ALL modifications from the vehicle. The IC has now been removed, and the Miltek is being done tomorrow. I'm going back on Saturday to remove the Forge DV/Spacer, Carbonio and they are doing the Fuel Pump.
The car is then being towed back to Seat in stock condition where they are going to carry out fault finding on the wireing, at my own expense. The car will then be sold from that dealer once it is fixed, on a sale or return basis that they have agreed to.
All the parts removed will be sold on here to any takers, and consist of:
Milltek 100 Cell Sports Cat w/3" downpipe
Milltek non-res exhaust from the cat back
Forge DV Spacer
Forge Pressure Related DV
Carbonio CAI and Pannel Filter
Forge Twin Intercooler (Almost new!) with all hoses and fittings
Didn't see it ending like this TBH, but if they want to get really crappy over the financing and playing the legal card, i'm more than happy to show them the middle finger and buy something else.
Thanks to everyone on here for being so positive though, and Seat or no Seat, i'll still frequent this site as it is excellent...
