Hi

No codes came up and I was watching it in live data mode

Not sure ow much 4 degrees affects fuel consumption but I understand it might have some effect.

Cheers for the video that is for a 2ltr with a separate thermostat ill have a good look round this week see where it is

right then i am getting close to the end of my tether with this car now.

the new thermostat and the new fuel filter that i have had delivered are the wrong ones even though they went by registration for the car

also the level of soot in the engine bay in the paswt 4 days has gone crazy this area was virtually spotless on thursday now look at it.





also found out it had a new turbo in april this year so have no ideas why it is looking like this now only 8 months down the line

any ideas?

Yep, I know exactly what that is. I had the same thing. You have a pre-catalytic converter leak between the turbo exit and the catalytic converter. That should be covered under goodwill by Mini.

Have a read here:

Hi

Is that the dpf or do they have both?

Could this be a result of having the dpf delete?

That would be the dpf, yes. It could very well be related to the dpf delete, yes.

So it might not be a turo failure?

It had a new turbo 8 months ago I have found out, so am booked in with the dealership tomorrow to see what going on

There is a possibility it is not the turbo and simply a bad connection between the turbo outlet and I guess your downpipe.

When it happened to me, it occurred immediately after work on my clutch. The dealership identified it as a leakage between the turbo exhaust outlet and the dpf unit on the side closest to the turbo.

They contacted BMW/Mini and headquarters in Munich recommended they change the turbo due to risk of internal failure of a turbo seal.

Since then, I have had no soot buildup, but I notice the car has slightly reduced power. The new turbo will be 1 year old in January 2013.

If under 1 year, it should be replaced/fixed (depending on the problem) at no cost to you assuming the work to change the turbo was carried out by the dealership. I don't know what the dealer will say concerning the dpf delete if that was not done at the dealership.

Left the car at mini in stoke today

Had a call late this afternoon the issue is the way the dpf joins to the turbo it isn't fully aligned so need to have the front end off to fully align and then the pipe from the airbox to the turbo needs to be replaced

All in its best part of £500 so hopefully it is perfect when I get it back and runs just right.

All this just after the dpf delete its been an expensive 2 weeks

The only good thing is my loan car

Which pipe to the intercooler did they replace and why? Was it the one from the intercooler to the throttle butterfly or was it the one from the turbo to the intercooler? Was it leaking or something?

Where is the thermostat on these cars? Is it easy to replace?

Lastly, is the flat spot gone?

Hi it was the charge pipe from the right hand side of the intercooler

The thermostat is on the side of the engine just under the fuel filter nice and easy to get to and change

The flat spot has almost all gone only a fraction left according to my wife.

Although her fuel consumption wad around 45mpg today so not the best but hopefully will balance out ok

Hmmm am reading all these posts about turbo lag, it is a very frustrating issue this. I have today changed the orange seal (small split), check movement in the turbo nothing then cleaned the maf sensor, ours does have a tuning box but even that doesn't help it. I think the next step is the crankcase sensor replacement, after that who knows !!!!
:-/. Good luck with your recent fix ;-)

Hmm I saw exactly where the crankcase sensor sits so its not a difficult job, I will also try unplugging the maf in ours and see, could be the same fault :-/ I do hope not cause they cost a small fortune :-(((((
