335d loss of power

ii335dii · 04-24-2017, 04:39 PM

Had a remap done this Saturday and have been thrilled with the results.
340bhp & 700nm

I was driving home from work today and saw a brand new Focus RS on my bumper. I couldn't help myself so pushed it into DS mode and floored it!
Safe to say I won that race, he couldn't even get close!

At the next roundabout he was on my bumper again, clearly quite annoyed.
I joined the dual carriage way again and did the same, this time nothing!
My 335d had become a 318..it was a slug until I reached 3000rpm where I felt the turbo kick in. The car drives fine and reaches high speeds (eventually) it's just the small turbo not engaging.

Anyone had this issue? Broken hoses or a dead turbo? Please help

Sounds like you weren't making boost.

Any error codes thrown? Have you looked for codes?

I've checked for codes and found none.

I think you could be right regarding a boost issue, I didn't realise the state of the hoses until I removed the engine cover earlier...think I'll get them changed!!!

Those hoses need replacing!!!

Got it booked in a BMW specialist to replace the hoses, hoping that sorts the issue!

100% a vacuum hose issue. 1 hour and £10 in silicone hose and it'll be like new. I've just done mine. Where are you based?
