Since I bought my mini one diesel the stop/ start has never worked . I have replaced the battery with a AGM battery. Still not working.Bought a diagnostic tool which diagnosed a faulty boost pressure sensor on the brake servo. Cleared fault. However stop/ start still not working. This was not a genuine BMW part. Should I replace sensor with genuine one as stop/ start still not working ------------- S j gee |

| I would stop speculating and get it booked into an authorised main dealer or reliable indy. Unless you are an expert you could just be wating your time and money. |

Just got a price off an independent mini specialist. £125 just to diagnose fault if anything comes up ! ------------- S j gee |

Don't know if it's the same as on my BMW 320D, but has a previous owner coded the stop-start to default to off? Does it work if you engage the stop-start yourself? I'd read that some people disabled it as it 'allegedly' accelerated timing chain wear/failure!?!?!? If someone's used Bimmercode, then depending on the model/generation, you'd get coding options something like this...  ------------- 2006 Z4MC Individual Ruby Black, Extended Champagne, Piano Black trim 2016 335xD M-Sport Touring Estoril Blue, Black Dakota Leather, M-Performance carbon/alcantara trim |

Hi , Thanks. Yes I will look into it as there seems no reason for it NOT to work. I did get loads of paperwork & invoices with it , it have a full bmw service history, However the previous owner could of had it disabled. ------------- S j gee |
