Never had an engine warning light come on with any of my mx’s. This morning it did and I think I’ve solved the issue - the little pipe on boost solenoid had fallen off. Would never have found it without looking on here!
Now to cancel the warning. Is there a simple trick to do that or do I need to go to a workshop?

Usually disconnecting the battery for a while does it. Otherwise a cheap OBD reader will be able to read and clear it.

I'd suggest unplugging the ecu, except that those suggestions are much easier! Especially since the nuts securing the kick plate protecting the ecu are non-tamper and difficult to remove if nobody has previously accessed the ecu.

Thanks guys - disconnected the battery for 20 mins and it worked! Luckily I knew my radio code!
