E60 M5 hesitation at 3.5k rpm

[dowzer]

I have a 2010 E60 M5 with around 30k miles - I have had it for about 8k miles and I can notice a slight hesitation at 3.5k rpm which last until about 3.8k rpm regardless of which gear I am in and regardless of whether I am in M mode or not. After it gets through this little bump it takes off like a scalded cat and is good right up through the range. Is this hesitation "normal"?

Car is due in for a service this week and I will mention it but I don't want to have to leave the car with them all day unless I have to especially as, based on previous experience of dealers, they most likely will be unable to find the hesitation anyway!

Thanks
Jase

Can't say I've noticed it.

have it in the garage and get a diagnostic done. could be a faulty lamba sensor or airflow meter etc.

I reckon something is amiss, at 3500 mine is ready to party.

Doesn't it state in the buying guide thread that once these engines get used to driving in a certain way they can develop "flat spots" where they're used to shifting?

Sounds like an excuse for a good thrashing anyway.

Yeah, as per the graphs on my buyers guide, but it shouldn't be noticeable to the driver.
