Well, months later....
The problem has been fixed. The intake hose between the MAF sensor and the turbo had a loose connection where it joined to the turbo. In fact, it was possible to wiggle the pipe right of the turbo. Dealership had to replace the entire section of piping between the MAF sensor and the turbocharger (apparently the clip and orange rubber seal and pipe are only sold as a complete kit :rolleyes:). The dealership replaced the self-adjusting clip with a standard jubilee clip and now the pipe sits firmly on the turbo.
Power is back and the fluttering/engine noise has disappeared. Car runs like it should now!
-----------------------------------------------------------------------
A small update on this. I was poking around the engine bay checking sensor connections, etc.. On the compression side of the turbo where the intake pipe joins to the turbo, there is an orange seal. It looked like it could be pushed closer to the turbo by about 2 mm. I did this. Then I wondered if it would move in the opposite direction. Well, turns out I can slide this pipe right off the turbo so that I can see inside the turbo itself. Pipe will then slide back on. It hasn't come off during driving, but I don't think this is normal. I think it should be firmly fixed, no?
I know most people on here have "S" versions, but the turbo on the "S" is the same Garrett unit as on the "D" model. Can anyone tell me if their pipe with the orange gasket is secure or does it move?
Can anyone with a dooper chime in maybe?
-----------------------------------------------------------------------
My car is a 2009 Cooper D Clubman. In December, the clutch and flywheel were replaced. However during the repair, the dealership damaged the turbocharger. The car was leaking diesel exhaust between the turbo and the cat (i.e. a pre-cat leak).
Mini recommended that the turbo be replaced due to the possibility of seal failure on the compressor side. The turbo repair was conducted at another garage than the one that did the clutch/flywheel job.
After the new turbo was installed, the car seems to lack boost/power/torque. I can hear the turbo operating, but there seems to be a distinct lack of power. This is especially noticeable going uphill. There is no soot coming out of the exhaust, so I am discounting the EGR valve.
The dealership that installed the turbo has checked for error codes and found none. The vacuum system has been inspected and they have found no leaks.
I've had the car sitting at idle and pumped the brake like mad until the pedal stiffened up. The pedal then creeps away normally as the vacuum rebuilds, so I too, think the vacuum system is ok.
The car idles and drives fine, except for the distinct lack of boost. The car is not in limp mode, it just feels naturally aspirated rather than turbocharged. The usual suspects - air filter and fuel filter - were changed, but no joy.
I have a number of ideas, but I don't know if I'm on the right track. I'm thinking of the following possibilities:
1) bad MAF? If I disconnect the MAF and try driving, what will happen? Will this be informative?
2) solenoid vacuum valve(s) (is there more than one?) - I saw this mentioned as a problem on the Peugeot forums which use the same diesel engine
3) dozer valve (is this labour intensive to inspect/repair?)
4) wastegate malfunction - although it seems to be functioning if I inspect it with the hood of the car up. Can't observe it while driving, however
5) something wrong with the charge air cooler that I'm missing?
At this point, if there is something I can ask the dealer to look at, that would be helpful. Any ideas would be highly appreciated as this is driving me nuts and I think it's not a huge problem, just something small that's being overlooked.
