The Dreaded Cel Light Has Come On

[mctwistuk]

Driving to work this morning the dreaded CEL light has come on.

Is there anyone in the paisley area that has a fault code reader that could help me diagnose the problem?

Cheers

Hi Chris,

Can't remember if you have an STI? As you know, I have the sportscat/decatted downpipe/up pipe on my

WRX...all by Meercat. Only time I had the CEL light come on was right after the up pipe and it was for the

EGT sensor prior to remap.

Guess that doesn't help!!

Nah mine is fine.. But I had it mapped soon after the downpipe was fitted. Am I right in saying yours isn't mapped yet?

[sparky_sj04]

What else do you have fitted just now?

[mctwistuk]

It is an sti richie. Still to get it mapped which will be getting done next month:-) no other bits fitted as yet as they will get done nearer map time. I will put this down to gremlins in the system.

I take it you're still going to get it checked out? There are those that would discourage running for any length of time even with the Sportcat fitted before the car is mapped. Wullie from Meercat being one of them...

This is where I made a mistake. I had my 3" system fitted about 2 weeks ago and im not driving it until I get it mapped on 22nd July so I have missed a few runs ect. Hind sights a wonderful thing! Bit stupid having the car sitting there doing nothing paying for tax and insurance. Roll on the 22nd

I dont put car on boost that often and drive it sensibly as i know it needs mapped. Will see if it ever comes on again and take it from there. I am in no way saying there is anything wrong with the exhaust i was just curious if anyone else had similar before mapping. Cheers chris
