Hi there,

Hopefully someone can shine some light on this issue.

It's a rev 2 turbo and the check engine light is coming on the dash intermittently when starting up and upon acceleration, however upon checking for codes by bridging on the diagnostics no codes are stored as the light is just continuously flashing.

Cheers

Indeed, you'll have the 89661-17380 ECU which is prone to leaky capacitors.

Bang on the money you two! 2 capacitors have leaked all over the board! Time to find a Rev 2 Ecu ASAP. Will repair the faulty one once I've got a replacement one wired up... just incase I mess up [thumleft]

Just repair the one you got as your only need to repair the other one you buy lol
I kept a spare rev 2 turbo ecu after suffering the same fate but ended up selling it on as once my old one was repaired i didnt need it.
