Hi guys,
Was heading down the M5 this morning so activated the cruise control (retrofitted by BMW).
As I called to speed up from 65 to 75mph the car hesitated before the power came in.
Then I had a warning message and the car went into 'limp mode'.
I'm taking it in to get the fault read tomorrow but anyone got any ideas?
Cheers for any help!
Andy

vanos solenoids or something being my guess.

No one can guess it needs a scan to get the codes out

Will update tomorrow when codes are read.
Could it be anything to do with the retrofit of the cruise control?
Not experienced anything like this when driving manually...

Probably not but you never know

I suspect it's just coincidence.

Whats the mileage on your car?

 

[AndyBish1M]

Done 29,000 on a 10 plate so not much

Have a look at your vac lines as low boost also throws the car into limp mode!
Few guys on N54tech & e90post replaced their lines around 25-35k due to splits.
Check both lines that run from the bottom of the boost canisters and from both recirc vales to the splitter then back to the engine all of those were split/cracked on my car and they had only been replaced 2 years ago (covered less than 20k in that time).
Is there no one on here around you that could check the code and reset?

Here is the thread I posted when I changed mine

Thanks drifterr
Will check tomorrow in the daylight.
Anyone near Bristol with a reader???

 

[AndyBish1M]

Now I am confused...!

Started her up this morning and drove to work with no faults whatsoever? No Limp Mode and Full Power available?

Taking her in to get the codes read at lunchtime anyway and will post what they are...

:?

Funny enough I had the same issue 2 weeks ago. I cleaned the vanos solenoids and "touch wood" it hasn't come back

 

[AndyBish1M]

OK Cheers
Taking to get the codes read in a minute so hopefully know more then...

 

[AndyBish1M]

Ok, had the codes read...

2DED power management quiescent, current fault intermittent

30FF turbo pressure measured too low, intermittent

Anyone got any ideas?
Cheers,
Andy

Check the turbo vacuum hoses for splits.

 

[AndyBish1M]

OK
Going to check the vacuum hoses and clean the Vanos solenoids as a start.
Could it be anything else, more sinister?
Cheers

 

[drifterr]

You mapped at all? Charge pipe could have cracked or come off.
To be honest I'd just start with the vacuum lines! Check the ones I mentioned previous, as as said all of mine were cracked/split.
If they are replace with silicone

 

[AndyBish1M]

Yeah got jb4 ...

 

[Ian83w]

Have u had any waste gate rattle as 30ff is sometimes the code u get for failling turbos check everything else 1st tho

 

[AndyBish1M]

No, got no rattle as I checked for that already...
