I was driving down the road st about 80km/h (canadian) and my half power light came on.. car didnt shudder or make any odd noises and still isn't making anything odd as of now, it idles smoothly, oil levels seem fine, no odd smells or noise when revving or driving.. what could cause the half power or " limp mode"?? New to the mini scene so I am quite worried it is something major, though I am hoping not.

 

 

 

I would have immensely appreciated that, but also, I'm way down in yarmouth haha. Is there a ns Facebook group for mini owners that you know of? Been trying to connect with some locals but all the ones I come across are in their 60s and wont wave back let alone pull in to a spot and chill haha.

 

 

Wastegate shaft wear is a very common problem with these cars. Usually shows up around 70k miles, search.

 

 

oddly enough, today when I was driving it to work I ended up passing someone on the road and soon as the car downshifts into passing the half power light just went away, I had gone through the cars code reset and it came back that night a couple days ago, but today it went away and the car seems to run smooth as silk again.. my assumption is that arose from the car sitting for a couple months at the dealership without being moved and now with me driving it, it was clearing things out of the system. That is me being hopeful atleast. But I am getting it scanned tomorrow.

 

We aren't all that bad. I'm in my mid 60's and always wave when I'm passing another MINI. Quite often for me, its the younger people who dont wave back....probably laughing at the old fart trying to be cool again.

 

I wave and honk Mikey T.
Its always for me
Get in there!

the code itself ended up being from an auxiliary water pump that helps out the intercooler, there is a recall on it through BMW which is great.. the not so great is that the nearest bmw dealership is a 4 hour drive away from me..

 

 

oh definitely worth the drive, especially where there is the 10 year warranty on the turbo itself so I'm going to tell em since this has happened I feel like the turbo needs to be replaced as well since it could have run dry and something internal could be warped. So free pump and free turbo for me come the end of November haha, thays if I dont replace the turbo with the borgen Werner jcw one first.

 

I've been getting instances of intermittent limp half-engine light for a while with my wife's 2013 R60 JCW. It only happens when applying power (giving it gas) or when the car downshifts at highway speed when climbing steeper hills. There is no noticebale drop in power (if there is, I can't feel it when driving). The half-engine limp code light goes away a few minutes after restarting the car. Happens in all kinds of weather (hot, cold, dry, damp). Can go weeks or days without happening then all of sudden... *bing*.

I have a BMW specific code reader and it reads 2C57 Charge-air pressure control, lower value: change-air pressure too low. Appears to be some kind of intermittent boost leak. Bringing the CM to my local MINI specialist so that he pinpoint where the issue is.

 

 

Agree with all the above, without scanning it you'll have a hard time figuring out what it is. If it's a internal code you need a scanner that can read BMW/MINI as a normal scanner will show no faults. Otherwise if you have access to ISTA that is the best way to check.

 

 

I'd love to go bigger haha, if only I could convince the local dealership my car is a jcw with a badge delete, but they VIN checked me already :( I am currently saving up for a tune, I've been in talks with Mario, and have decided it's my best bang for buck route to go, then a helix stepped intercooler and then probably bigger turbo and call it quits before I turn my family car into track day car haha.
