Hi , my first post here so thanks for having me .

I bought my 2013 640d Msport 80k miles about 3 months ago.
now whenever the car has been stood over night , on its first drive of the day it has very low power , and doesn’t shift gear when it’s should, as if it’s stuck in a “limp home” mode or something like that, it feels like there is no turbo pull and the turbo whistle seems a little louder (no warning lights or errors), it’s a similar feeling to if it was stuck in eco mode or something

if I stop the car and switch it off for about 10 seconds then start again it then runs absolutley fine for the rest of the day until the following morning when it all happens again. The issue only comes on after the car has been stood over night.

do these cars have problems with EGR valves or anything like that or can someone help diagnose it

I had exactly the same issue on mine and it was the inlet manifold all coked up. When you start the car in the morning the swirl flap actuator does a sweep to measure the start and stop positions of the swirl flap linkage. Due to being clogged up the readings are incorrect making the ecu think the linkage has broken. It only does this sweep on initial start up which is why it returns to normal on a restart. To fix it I removed the inlet manifold and cleaned it out with petrol, brake cleaner and a pressure washer. This got it looking like new and the swirl flaps then moved freely. You then have to put a new stop point on the swirl flap actuator as wear in the linkage makes it again go past the point it should again making the ecu think there is an issue. The final bit is to reset the air mass adaptions. It is pretty straight forward as a job and the trickiest bit is putting the new stop on the actuator. There is a post on another six series forum with pictures of how they did it by putting a screw in the actuator housing. Also if you search on this forum you will see my original post when I had the issue. You could put a new manifold on but they cost approx £870. Mine has been perfect since.
cheers

Nice one Jim thanks for that.

I’ll have a look see if I can find the original post. This now points me in a direction to have a look appreciate it

If you can scan for codes if it is the same as mine it will throw up code 2c3200. Also this link will show you the modification that you need to do to the actuator. I didn’t use a screw but put some metal putty on it and made a new stop.
it’s a bit of a faff to take the manifold off but not difficult and all new gaskets were about £90. I was shocked by how clogged up it was but now runs great.
cheers

Thanks again Jim

You mention re setting air mass adaptions , is this done by computer or by the car

The air mass adaptions need to be reset by a diagnostic tool. I considered removing the swirl flaps but the way they are constructed there was no need and when I did it on a 635 d it caused issues with the dpf. When the manifold is removed you will be shocked by how much gunge is in it. The most important bit is to ensure you manufacture a new stop position on the actuator.
cheers
