Limp Mode?

Hi All!

I own a BF mk2 2009 XR6 Turbo auto. Recently I went to track day, and spent all day just doing laps around Wakefield track.

About 4 hours later, I noticed my car wasn't hitting as hard as it normally does, I looked down at the dashboard and the D for drive was flashing on and off, I tipped it over to tip tronic and it was stuck and locked in 3rd.

I took it immediately off track and it went back to normal with the D not flickering and able to change gears again.

But now a days I drive to and from work, not thrashing it at all and about 10-30 minutes (varies a lot) into the drive the car with flash the handbrake, the traction control and the ABS on and then it will lock itself in either 3rd/5th gear depending on the speed at which I'm traveling at the time.

Also little things will be effected such as reverse lights and sensors do not work when its locked, the lights on the ICC will dimmer and brighten whenever, my HID lights will flicker on and off to its own dance (left right both) and obvious its not in the right gear so taking off from 5th you can imagine is insanely frustrating.

Every time I turn off the car and restart it ALL problems go away, but sure enough after a bit of driving the same thing will kick back in.

I assume it's kicking in to LIMP MODE?? but you can assume right I'm still a newbie at all this so any help/advice will help A LOT what should I do???

Is there something I'm missing???

PLEASE HELP

CHEERS

I thought limp mode was when it started shutting down cylinders pretty much so the car is undrivable and must be turned off and restarted, although I could be wrong. Yours sounds more like a dodgy electrical fault? just my thoughts I am not a mechanic...

No, as the lads have stated your symptoms are nothing like limp mode - that is when the car loses nearly all power when the ECU knows the car has overboosted (engine self-protection mechanism).

I would take the car to a (decent) auto-electrician ASAP, they should be able to steer you in the right direction as to what fault you have....might be something really simple, but it might not, especially if you have thrashed it :shocked:

I had a problem with mine doing a similar thing with the blinkers and other electricals. May sound silly, but do u have an aftermarket immobiliser or car alarm?? Mine was the car alarm, but had speaker turned off lol

That handbrake light I think you have mistaken for the warning light, I dont know if it is related to the eng or other. But I mistook that light as a handbrake one once when the abs and traction light was on turns out its not handbrake.

The gearbox in 3rd sounds like a gearbox limp mode but the other stuff is probably electrical like others have mentioned.

sorry mine the last of the BF mk2.5 if anything! 2008, sorry not 2009!

Nah no immobilizer no alarm! some mods and all but nothing recently except for trackday, so it must have cut so sensor or something!

Yeh I thought it was limpmode too but I guess not cos sometimes it will kick in to 5th gear and other times it will kick in to 3rd, and from 40km/hr plus in 3rd gear the turbo and everything still hits hard so I assume its something to do with the wiring but again I got no idea!
