Plug seat belt in, keys on seat and press the start button, I know I have had 3 new tyres in 5000 miles, also the pump will reach the front tyres if you go through the inside of the car.
I can second everything said here. Bit of a change from any other cars we have had and with wife's recent slow puncture I have got very good at snaking the power cable through the car to the front tyres. Sometimes I got fed up and just parked next to my car and powered it from that. I have to say that not being able to run the accessories without first getting into the car and then having to ensure seat belt is fastened seems aver German way of doing things compared to every other car on the market!

Yes, you are missing something. You need to turn the ignition on and leave the keys in the car. You can then carry on with pumping up the tyres.
I know I should check but does the included inflator reach the front wheels from the 12V socket in the boot?

So, I can't strictly answer this question because I used a separate tyre inflator that came with my wife's old car rather than using the one provided with the ID.3 (as I thought I may as well leave it unused until I didn't have another). However, with that one, it reached the front tyres ok, but only by putting down the back seats and passing the wire through there from the boot, then through the front door on the correct side. I'd be surprised if the ID.3 one was shorter.

Many thanks will try it.

Hi, I've just joined the forum for this exact issue!

I had a puncture and needed a rescue service as when I sat in the car (with the wire running out the passanger window) the compressor worked - but as soon as I goto out of the driver seat it stopped! So the answer is plug in the seatbelt is that right?

As with every other issue I've had with my ID3 (I've had many) my local VW garage has not been able to help. I feel like the car is an experiment on wheels that they just weren't prepared for.

It's nothing to do with the seat belt. You just need to turn the car back on using the button on the side of the steering wheel column. That button's main point is that it allows you to turn the car on without being in driver's seat. It's in the same place as the ignition usually is on ICE cars.

Yes it does. It'll reach every tyre from there without snaking through the interior. Your biggest challenge will be getting all the power cabling back in the tiny recess on the back of the pump.

My wife's Family has a very slow puncture on the rear drivers side tyre, it's been there about 6 months, dropping from 2.6 bar to 2.0 bar and triggering the low pressure monitoring over the course of a fortnight, so I pump it up often.

If you have a slow puncture for such a long time.Do you not think you should pay the tyre repair garage a visit.Another tip for all owners new to tyre monitoring,the battery that powers this feature does need to be replaced and when coming to the end of its life , you will tend to get the tyre warning light coming on.Check your tyres if there is no apparent air loss ,replace the little battery that powers the tyre monitor at your next servicc.

I just had a quick look at the VW online manual and couldn't find any reference to the tyre monitoring battery. Any idea where it is?

There isn't a battery, the ID.3 system works via the ABS, if a tyre a flat the wheel rotates faster. It's not like other systems that display actual tyre pressures etc.

As it's so slow, hasn't got any worse, and there are no visible signs of damage to the tyre, I haven't felt the inclination, no. The Bridgestones will all be getting replaced in the not too distant future with (almost certainly) Michelin e-Primacy, or Primacy 4.

Big GT is correct in the tyre monitoring system's operation.- no modules inside the wheels, no batteries. Just the ABS/XDS systems monitoring individual wheel rotational speeds as a result of effective rolling radius changes from stored values, hence why the tyre pressure reduction isn't picked up from 2.6 to 2.1/2.0 bar - the rolling radius hasn't changed significantly between those inflation values to be picked up by the system.
