When I had no luck with my dealer Suzuki, the nice lady at Suzuki said all dealers had been sent a memo in ref to the ECU replacement, I guess my dealer does not read his
After much denial from my dealer I asked Customer services if they would ring dealer as I was being fobbed off by them, CS lady said she would do this for me
5 minutes later the dealer calls me to say I am approved for an ECU change
Maybe I'm a sceptic, but if anyone else has problems getting an ECU change from their dealer give Suzuki customer care a ring on 0500 011 959 and ask them to ring your dealer to sort the issue.
Also worth saying to CS at Suzuki that you have looked at your ECU and know it is an 000 version and that it has often caused you to stall the bike, which results in you nearly dropping your bike and you are worried that if it stalls at the wrong moment it could result in you having an accident. Mention this forum and thread, they are aware of it.
