  1. Most people won't keep a car long enough to find out that the life of the engine, transmission etc is shortened. How do these aftermarket tuners know what is safe ? Short answer, I don't think they do. Manufacturers spend huge amounts of money developing components, test them to destruction under extreme conditions in some cases. Then someone with a bit of engineering knowledge (maybe) comes along pushes things 20%, 30% or more past the manufacturer's limits and proclaims it safe. What testing have they done to be able to promise that ? Probably none at all. But a lot depends on how the car is driven. If someone does an engine remap just to get a more responsive engine in normal driving, drives conservatively and rarely uses full throttle or gets anywhere near the redline, then the risk is probably small. But then you'd have to ask why do it in the first place.

    Remap or not?

    I don't know about these particular engines, but I think it is often more than just being de-tuned with a different map - there are other differences usually as well to go with that. An old example on the petrol side - the Audi TT, two models 180bhp and 225bhp. Same block but many differences, including different exhaust, and a different turbo.

    Remap or not?

    I don't believe in remaps either. BMW have some of the most skilled engineers in the business. If that level of power was available safely and reliably, it would leave the factory that way. Yes I get the point about compromising to minimise emissions but in my opinion if we care about the planet and people's lives then we should respect that compromise as well.

    F11 530D Turbo recon

    Yeah, the manufacturers would never sell any turbo cars if they had to advise people to do that. 20 odd years ago I had a petrol turbo and I would always do that - when a couple of miles from my destination, drove gently if possible so the turbo had less work to do, and then let it idle for a while before I switched off. Technology has improved a lot since them though, both turbos and engine oil, they are more tolerant now of just being switched off immediately, but it is still good advice and I'd do the same today.

    225/45/17 instead of 225/50/17?

    Speedo is out 2mph at 60mph ? I don't see that as a problem in itself.

    It was £20 I think. https://www.themasterlocksmith.com/product/bmw-key-repair/

    What did you do to your E39 today ?

    I switched to 5w-40 from 5w-30 a couple of years ago and the engine is quieter when cold but about the same when hot which strangely is the opposite of what I'd have expected. 5w-40 seems the right thing to do for an older high mileage engine but in reality I'm sure it is fine on either.

    E60 Petrol engine buying advice

    The first E60 I test drove was a 2006 N52 525i. In hindsight I should probably have bought it, although it had 20k more miles on it and was more expensive than the 2004 530i M54 that I ended up buying a couple of months later. Quite hard to find the N52. By that time most were buying diesel, and the N52 was only available for a couple of years before the impressive but flawed and troublesome N53 arrived.

    Congrats ! So how was the 3.0l N52 ?

    Great good luck !
  13. Very compelling. But how many times have you ever aquaplaned ? Never in my 40+ years of driving. If you drive to the conditions, then that shouldn't happen. In real life you wouldn't go that fast in that situation. So I think that is mostly theoretical. Perhaps they should have done some emergency braking tests in those two cars ? The car with the new tyres on the front may stop safely. The car with the half worn tyres on the front may slam into the car in the front. For me there is no choice - staggered set-up so I cannot choose. Currently my fronts are due for replacement in the next 12 months. They will get new tyres, and yes the rears will be half worn. I have no concerns about that.

    What does this warning light mean ?

    Perfect, thanks ! Yes I see now it is the pic of the door and window
