Exhaust warning light - Powervalve 200 cell
AJP:
Just had the exhaust waring light pop up, in amber, not flashing. The car feels and sounds fine.
It's Stage 1 R-Tech with a full Powervalve (200 cell sports cat). Exhaust has been on the car for a couple of months and all has been well. I'm due to visit R-Tech soon to tweak the map to the exhaust, but this is purely for performance as the sport cat shouldn't bring up any errors like a decat does as we all know.
I know it's often a lambda issue that brings the light up, but could be a few other things. Just wondered if the fact the cat/downpipe isn't standard is relevant at all, although everything I've learnt tells me it shouldn't.
It's in at VW for a major service on Monday as it happens. I'm trying to decide the best course of action - if the light has cleared by then I might not mention it, I don't really want to pay dealer prices for what might turn out to be a sensor plus labour. Only reason I'm taking it to VW for the service is that it's had VW all its life, so I see some value in continuing that for when I eventually sell up.
Thoughts?
Paradox1:
I was under the impression that even with a sports cat, you can still get the engine light on as the flow has increased. If the car drive as normal then that's what id put my money on. nothing to worry about, a map with sort it

Do you know what code it'd bring up if that is the case?
I'd expect the light to have come on pretty much straight after the exhaust was fitted though, not months later.

@Powervalve Nige Any thoughts?

Its the cat. Either fit the original or book it in with Niki
