Well, there may be some protection from the base stock, but that will come from the 5W rating pumping up pressure faster on a cold engine.

Even if they're the same diameter, vented discs are typically about 3 times thicker than solid discs from one wearing face to the other. So I'd expect that you'll need new calipers.

It's an advisory: ignore it, especially since it may not be repeated next year, or even at a different MOT station.

It's quite possible that all the hardware except the control switch(es) is present, and it's supposed to be disabled in software.

That may be your problem...

Such a Agra Engineering, Brodie Britten racing and Mountune for example?

I don't like the sound of that either, but since I have no idea when they occur, I have no idea what causes them, just that I don't get this issue on VAG, PSA, Ford, Vauxhall or Rover group cars (and haven't in over 30 years)

Zeer goede meneer @e-Roottoot.

Never needed more cool down on a TDi (any make) than a couple of minutes in a 30mph limit and manoeuvring.

Accepting a Nissan Terrano is also grounds for voiding the contract, due to "want of understanding" ;-)

Are you getting other electrical gremlins, like with fan and/or radio head unit turning themselves off, ABS (and/or traction control if fitted)? If so, then I'd suspect the actual problem is with the alternator control wires, alternator clutch or battery. The cheapest of those to fix (and easiest to diagnose by text) is the alternator control wires. Do you get an alternator light when you switch on but don't start the engine? If not, then it's the control wires almost for sure.

Pretty much yes. It's based on knowing a couple of actual tyre fitters.

I never said otherwise; what I said was that this limit is legally unenforceable, that is that any attempt to prosecute (criminal or civil law) for, say 8mph in a 5mph zone will fail, so as long as you are driving carefully don't sweat it!

As was my original reply, based on idle in first being the best steady low speed pretty much any car can achieve.

If you don't have a tyre machine, your only recourse would be to go weight off wheel(s), blow them up to about 3 bar (45 PSI), then deflate to manufacturer's recommendation for model.

Well, I thought, having actually seen on-car shots from both competitors and from a camera looking along the track from behind them that it was more "GR puts 2 wheels on the grass, then blames Valtiri for him having done so". Also highly unimpressed with DC for taking GR's word for it then trying to recant without actually apologising after he realised what happened.

Also ISTR that a 5mph "speed limit" is actually legally unenforceable because it is below the minimum speed that a lot of speedometers will register anything other "needle on the low end stop" at.

Any reputable brand 5W30 will be OK for an SDi running this change schedule.

Not the foggiest, but that is about idle speed in first gear, which will be sustained by the idle controller on most electronic injection systems.

Well, it's not unknown for competitors who get on with driving/riding their own machine rather than whining to the meedja to report that they made a faster lap when being slipstreamed than by themself. Perhaps Mir needs to learn to ride?

Neither do I, mostly because there is no signature in that post to read.

Well, given that it's thrown an EPC, maybe read the fault codes rather than playing a "throw money at it" lottery?

No sign of MM93 throwing his bike at marshals in free practice and under a double waved yellow then?

Well, that suggests a resonance coming from the tyres or suspension. Would your garage be able to lend you a set of a different make tyres?

Well, I'm still wondering about a loose heat shield, most probably above one of the cats, or between the back box and the fuel tank, or on the exhaust manifold. Other than the manifold, these require a manual inspection, not just a visual one.
