Speed limiter

[M3greg]

Possibly a silly question, but how (without risking it on an empty motorway ;-) ) would I find out if my M3 has had the speed limiter raised/removed?

Secondly, is it 175 or 185 mph that BMW raises it to?

Thanks, Greg.

Get someone to check the ecu? Air field track? rolling road?

Cheers Ady. Don't suppose you know if BMW did an option to raise it, and if so what to? I think Audi do a 175 raise from the 155 all German cars seem to be set at.

Cough, not all German cars.

In some markets (which includes Germany) there is an official option to have a 'performance upgrade' which increases the limiter from 250kmh (c155mph) to either 275kmh or 280kmh.

I remember seeing it in the back of my M3 handbook - but haven't noticed anything in the M5 paperwork.

Cheers - what I was after.

If you check on here http://www.rubmw.ru/vincode/eng/
with your VIN (looks like you need to register now) you get the build sheet.

On mine it's listed as 'S231A Deleted : 250km/h limitation'

With that option there is no engine limiter, just stops accelerating at about 185 (indicated).
