Have OBDII codes ECM-26A0, ECM-26B0, and ECM-6663 which the reader doesn't have a look-up for.

Does anyone have any ideas?

XC70 D5 2006

Thanks!

Yeah, I do have Google

Funny, I searched but they wouldn't come up. Hmmm. Odd. Have now found, though e.g. ECM-6663 only has one hit/explanation - which is on this forum too, and I searched that too. Perhaps everyone was out watching the Footie.

Anyway

ECM-6663 = Glow plug relay faulty signal also has a comment: "The engine starts fine, but is a bit lumpy at tickover for a minute or so." Funny, that's exactly what mine does

ditto single hit: ECM-26B0 Injector Power Signal too high cyl. 5 - ditto this forum, ditto lumpy running, well, a "misfire", doesn't say whether just at start-up.

So, got there, thanks.

Have cleared these and they have sometimes come back, sometimes not. No warning lights/messages up etc. Shall just wait until it Breaks Properly, I think.
