Hi all. What's the meaning of the bottom right light on the stack dash? If it stays on does this indicate an EML code? I can believe it if so as I've just changed my backbox from VSE to turbo std (well, BoT did).

Yep - that's the engine management light highlighting that there is a fault code.

 

My guess is it'll be to do with lambda sensors if you have just changed the exhaust.

odds on the post cat lambda sensor was plugged into the wrong harness connector (two in the same area which both fit :lol: )

It wasnt unplugged but I guess it has been disturbed. Or could it be breathing differently means its returning a different value which it doesn't like?

Yes, the wiring can get brittle over the years, and break when moved. 

Get a code reader out, get vauxhall to read it for you, or find someone local with a reader.

From the code we can tell you what wire is broken.

 

Some wiring can be fixed, but if broker near the lambda itself, you may need to buy a new one.

Assume you must have the silver VX that was up on the ramp when I dropped my red VX off at BOT this morning?
