Okay here we go again. I have driven the car for just over a 1000 miles with no problem . Hard acceleration when needed, and tonight took the Grandis up to 60mph plus and yes it went into limp mode. Thought I had it sussed , but to no avail. Get my head scratching again . Just what could it be.

 

For £25 and a half hours work I would change the MAP sensor but only if it's an over boost fault code that you are getting.

 

Might be a good idea anyway . What I find annoying is that when I replaced the pipe the car drove well and lasted for over 3 months with no problem . If it is electrical fault surely it would manifest itself earlier, however it must be related to extreme pressure under hard acceleration. Could it be another hose playing up. Surely someone knows exactly the fault. The car is. 2007 and maybe something is just wearing out.

 

It is the variable turbo vanes... In 98,9% of the cases...
I got rid of my Grandis because in Finland the turbo replacement would have set me back 1500-2000€. I sold it to a guy with mutual agreement of knowing there is a turbo problem. I deducted the 2000€ from the sales price and got rid of the problem.

 

Have you checked the turbo. It is this almost all the time. Its a bad design where the variable vanes carbon up. Remove it clean it and refit it. There is no short cut. Sometimes its the boost sensor, sometimes its both. People sell these cars on after getting a whapping 1500gbp repair quote and thats why there's so many going around with this fault. I sorted mine for free by cleaning and replacing it. My brother in law had exactly the same fault with his Grandis and they part exd it in after only owning it 6months and so it becomes someone else's problem and the cycle starts again....

 

I have a Mitsubishi Outlander 2007 I have had for nearly 2 years and have been having the same over post problem, has any one found a permanent fix because I can't bare it anymore, I'm hopefully gonna get it booked in to Mitsubishi tomorrow as the engine light has now come on again but it Is not in limp mode.

 

Did it fix the problem?

 

I have listed already the permanent fix. Mine never went wrong again. Make sure its overboost 1St which will always put it in limp before you switch off and on again and it will be the variable geometry turbo. Mitsi will only replace with new including manifold and charge you 2500gbp, after a 100gbp initial diagnostic fee. If it is this fault don't waste your money

 

So I need to replace

variable geometry turbo

But best not to take it to Mitsubishi will independent garages replace this and how much did it cost you?

 

Had a drastic power loss with my 2008 outlander 2.0did 122k miles. Happened twice over two weeks, both times the rubber pipe from the turbo to the inlet manifiold had come off (once either end, the one down by the rad offside). Symptoms were; unable to rev over 1800rpm withouut car juddering, driving under 1500rpm enables you to get to 60ish but very slowly. Had a subsequent fault diag done (engine management light never on), this showed 3 codes (673h/1651 672h/1650 671h/1649) all undocumented by garages reader but they seem to imply overboost. My conclusions (amateur).
1. The clips had worked loose over time (garage said this) - job done.
2. The pipe has become weak over time (that will be the next fix if it recurs).
3. Check MAP sensor for signs of damage.
4. Get turbo cleaned as it could be vane sticking issue, could be causing the fault if overboosting.
Hope this helps others and draws on the sterling work of those in earlier posts.
Thank all.
