    about a week ago, midway through driving normally, the engine and TCL lights came on, and the TCL light was not able to be turned off with the switch.
    but after parking the car and coming back an hour later (went shopping :p) it was fine.

    now its done it twice in the past week, and today it did it, but then after turning the car off, and back on, they weren't on anymore.

    ok, probably alternator then. There is a chance it could be a wiring or sensor issue, but more likely to be the alternator.

    One thing I'm gradually starting to understand (the expensive way) is that Legnum alternators really don't like being jump started. I've now got an Evo 7 with the same problem.

    battery is holding 12.7V, and the alternator is charging at 14.3V, so neither of those is the problem.

    what sensors or wiring could be the issue?

    it may be co-incidental, however it only seems to happen when i have turned TCL off to begin with... after a while the engine light will come on, and i cant turn TCL back on

    might be something to do with a sensor then?

    Hey Guys,

    Sounds more like the system is throwing a fault code.
    I would suggest checking for this.

    Check the thread where i was talking about my TCL system. Sounds a bit like some of the problems I was having.

    Regards
    Gavin

    Hey guys, ok first up mine is doing the same thing as well, driving normally and them BAM TCL and engine light come on.
    I doubt its the Alternator as i have just had mine re-built 3 weeks ago (touchwood)
    I tend to believe its a wiring or sensor issue, as i havent had any loss of performance or notice the car driving any different when it happens,
    i put it down to Gremlins in the wiring...
    lol

    I have had the same problem when I did my engine work. If you accelarate heavily enough so as to get the TCL to work, the light used to come on and so did the engine light.

    It is usually caused if there is a leak in the vaccum pipes going to the white cylinder(left side firewall) from the throttle/plenum assy. There are also 2 solenoids on the firewall that have vaccum pipes going to them that should be checked. The white cylinder holds vaccum even when there is no vaccum in the plenum due to WOT or boost conditions. That vaccum is then sent by a solenoid to the vaccum diaphram which closes the throttle slightly so as to reduce power and maintain traction.

    In my case one of the pipes going to the white cylinder had a leak. Just had to snip the pipe slightly and re-attach.

    Could this be from a Boost Controller or Boost gauge leak or factory BOV leak?
