General Car Chat / Re: BMW i4 M60 Arrived

« on: Yesterday at 07:49:04 »

Not tried the pre-heat thingy on Mrs Opti's I-Pace, or the heated steering wheel.

But I grew up with ice on the inside of the windows, so such things have a touch of the 'nancy boy' about them.

one of the best features, so nice coming into a warm car. You almost don't need a heated seat or wheel

We tried the 'preconditioning thingy' last night before driving to the supermarket...... preheated car for about forty minutes.

Car was good and warm with no misting up to clear away.

However, car was not plugged into the zappy and lost 3% of charge.....94% down to 91%. Hmm.

Its a 7kW heater (hence the range loss when ran for forty minutes), you only need to run it for five to ten mins

I am not old enough to play golf, and I suspect i never will be

I heard the latest release had a photo of TB with Epstein's dog

With the features switched off, I'd expect no impact of charge level over a few days, as it's only powering alarm, entry system and telematics really.

Been a lurker on Tesla groups, when they were on the short list. There is a 'phantom' drain issue there, but I think it's due to all the cameras and sentry mode etc. Not unheard of for considerable amounts eg 20% of power lost in a week. Other functions like a climate over product to cool if car gets to hot etc are on by default.

So far the i4 is just like a normal car just that the power plant is electric. None of this pointless Tesla style EV extra functions.

Sentry mode will always eat power (it uses the ADAS processor which is a water cooled monster), other than that it should be circa a 50mA 12V drain which can either be taken from the 12V battery or from the traction battery via the DC-DC, but, it will be pretty insignificant on range/percentage calcs

General Car Chat / Re: Merc MAF code

« on: 02 February 2026, 10:21:56 »

If you clear the codes do they instantly return, or only when revved/loaded?

The code is saying the MAF is not seeing the weight of air it expects for the engine operating conditions, that is usually as a result of gas getting in/out when it shouldn't (hence the question about the EGR as if it is clogged/stuck shut then the MAF would expect to see less air, if stuck open, then the MAF would expect to see more air, remembering that on a diesel, MAF is open at idle and closes as boost comes on)

DPF diff pressure very low and yet there is a back pressure of over 1 bar?

What state is the EGR?

Looks like the chinky super-embassy has now been given the green light.

.......oh, and Trump has stuck his oar in about the Chagos surrender.

Looks like Starmer's constant 'rimming' of the orange man has made no difference.

I agree with him on that one!

Another day, another compensation claim going into Chiltern

The UK rail service really is crap. And expensive

There is a real scam you can do with that, people buy an open ticket, use it, then look at the actual arrival times of the trains within the ticket window, and claim against the worst ones!

I thought you were a scouser, so surely its around 13-15 years?

If you want crazy, then this has to be up there (with Opti's favourite Signum engine featuring  )

The cassette motors generally have a sub board in them to regulate the speed, so check the motor (or swap it) and also check the mechanism for dry grease, tight spindles etc

You should be able to see an arc across the electrodes when it is trying to ignite?

Removed it (and the ignition transformer) and there is a nasty crack across on part of the electrode. Connections were also black and brittle. Unlikely to get a good spark, I think.

Black transformer box is bloated and puffy. I'm guessing it is the original from 1999.

That fracture is likely to result in the HT generated by the transformer arcing to ground rather than across the electrodes where it is needed, definitely needs replacing

The era you describe is unlikely to be 100% mcu controlled, from personal experience, there is usually a transistor circuit that is used as de-bounce, I have seen these early SMT transistors go leaky and cause all sorts of random issues with operation (repaired many of the Vx high end stereos with this issue!).
