Re: Tyre profile info please

They're like 5% bigger than standard? 33mm?

That's a lot more than I'd usually recommend, I couldn't guarantee they're not going to rub, especially at the back.

Re: Sorting the damping

Does anyone know the rear spring rate on an M240i? Or the dimensions (wire size, number of coils, diameter & length) so I can calculate it out?

Re: 03/17 M140i - 28k, Major Service?

The second engine service usually happens between 32k and 44k (as a very rough guide), and does include spark plugs, air filter, etc.

Or at 4 years if it times out.

9.5J ET33 won't fit even with a 245/30/19 stretched on, sorry.

13k, wow, very low mileage.

Shouldn't be the chain then, or anything mechanical really.

Gearbox rebuild/refurbish/replacement most likely.

Re: F21 2013(63) grind into second gear at high revs

Either you're not mashing the clutch pedal fully into the carpet, the clutch line has air in it (both unlikely), or the synchromesh is worn.

Re: Common 1 Series Problems

If it's a stone it won't be throttle related, and presumably they'll simply be able to remove it for you?? If it is only when you're demanding high torque (full throttle), could be the differential, gearbox, prop, etc. All of those are loaded up when the power/torque is maxed. How many miles on her?

Re: Randomly braking when wipers are on

BMW's 'wipe' the brake discs when it's raining (wipers are on). The DSC module very gently applies the brakes to dry them, not enough for anyone to notice though, if the car is healthy.

If you have a faulty/sticky calliper, they might actually grip a bit?

It should be covered by BMW's 'MOT Protect' shouldn't it?

Re: Brake pads - 6mm of meat left. How long?

they're usually around 12mm when new.

If you're at 6mm after 62,000 miles, I reckon you could safely do another 20,000+ with your current usage/driving-style.

Re: Track Day Oil Level (N55)

I'd want it at least maxed, or even marginally over-filled. I'd add 1/3 of a litre.

Yup, very fine ferrous silt.

Only takes one bottle of 75w140 LSD oil, cheap as chips to DIY.

Re: MP LSD fitted - Wow!

My Drexler got an oil change at 25k (added 'M14 Dimple' magnetic drain plug), and 50k. At 25k I'd say it needed doing, oil looked quite black/contaminated. At 50k the oil still looked comparatively clean and fresh. I'm guessing either the initial break-in was a bit abrasive/'messy', or that the sump...

Re: F20 Buying Advice Needed Please

Check for any signs of coolant leaks, the engine should be completely clean, no dribbly witnesses. 116i and 118i are basically identical, the 118i has a slightly different exhaust but it's not a big difference. The expensive options are Auto-box, Pro Nav, Harmon Kardon, heated electric seats, Adapti...
