Take it to MINI ... could be the a serious problem like a compression issue or could be something small. Maybe plugs fouled?

 

Check your belt.

 

the belt are ok

 

How old is it, what's the mileage? When was the last time you had any service done?

 

I smell a bypass valve

 

^^^^+1.

 

<sniff, sniff> it definately reeks of BPV.....

for Sara's sake, i hope so.....

 

it is a 2003 with 42000 miles

 

I have 0.2bar loss.. I couldn't understand the failure nor the MINI dealer... have any ideas? So i can check one by one

 

i think most cars that have problems with the BPV tend to be earlier models, so i'd say definately give it a shot.....won't cost you anything to do it yourself, or it shouldn't cost too much to get a mechanic to do it....

 

so just take it to te mini shop or buy a better one and do it my self... where can i buy it at... and why does it take soo long for my post to come up
