Question Power Loss / Limp Mode (E92 '57 320D)

Ok, thought I would ask on here if anyone could help as my local garage don't really seem to know the answer to this...

I have a 2007/57 E92 320D that I have owned since January, not long after I got the car I had it remapped, it was a superchips remap and everything seemed ok and it made a good bit of difference to the way the car drove.

Then one day on my way back up to work on the M5 I was sat in the middle lane at 50 on an average speed bit and got to the end and decided to pull out and overtake the car in front. I was in 6th gear at the time and pulled out into the outside lane, turbo spooled up and as it got to what I would consider the boost range the car just kind of died, I couldnt rev about about 2000 revs as I pulled over onto the hard shoulder.

I sat there and revved the engine and it just rocked the car and had no power, so decided to switch it off and back on again, revved the engine and job done, back to normal and I carried on my way.

Its now done this about 3 or 4 times now, mainly on motorway and mainly on a decent amount of acceleration.

No warnings on the dash, nothing came up on the diagnostics.

Anybody got any idea what this could be? As I dont want it to get any worse.

Cheers, Alex

I believe your remap you have is high. Contact superchips to send you a milder remap and i believe that the problem will go away.

as above I am thinking the map variables have been set above tolerance limits and car is going into limp mode once it is exceeding those tolerances to prevent majour damage hence why when you switch car off and again it is fine as its reseting

Thanks for the responses guys, I was thinking that it was some kind of overboost problem as it was only when I was at low revs and putting my foot down.

Think I will go back to where I had it remapped and ask them to tune it down a bit.

I did get a result of 232bhp on the rollers when I had it remapped which I thought was a bit high for a 320D remap!

Cheers, Alex
