So, it sounds like the MY2012 cars count differently from the MY2013 cars. Come to think of it, I believe this was mentioned before by someone on the forum.
I just assumed it calculated the general life of the oil using a standard ICE algorithm but I guess later updates include time.

Dealers probably complained people didn't need their oil changing if mainly using EV mode :unsure:

Tyre rotation always seems to be a big issue in the US but rarely ever mentioned in the UK.
The US has a history of everyone driving powerful rear wheel drive cars. With straight roads, low speed limits and too much power rears wear first. It's generally safer to swap the good tyres onto the rear as the average driver can cope better with understeer than oversteer.
The vast majority of cars in the UK for the past 25 years or so are front wheel drive which tend to hardly wear the rear tyres at all. Rotating the tyres to put the less grippy ones on the rear could create unexpected handling characteristics, e.g. lift off oversteer and unstable braking, which is why it's not promoted in the UK.

I have just completed a quick 2500km trip in the Ampera, taking in a UK service along the way. I saw only one Ampera during the entire journey, through Germany, Holland, Belgium, France, UK and back again. The fuel economy over longer distances (and without the ability to charge the battery) was around the 50 mpg mark, which tallies with my previous trips. In fact, it was remarkably consistent, with economy figures of 49, 50, 50, 66 (with charges), 42 and 47 mpg for each of the tanks I used.

I was finally able to have my spare key programmed and the car received the upgraded tailgate struts, which was an outstanding warranty issue, plus a new driver's door handle, as the button was no longer working. One of the rear tyres - with a full 7mm of tread left - required replacement because it had collected a nail. Fortunately, the company picks up the bill for all of this, so I also took the opportunity to buy an official rubber boot liner & cargo net and fit a 32A Rolec wall pod. The latter works well and I made use of it to charge during off-peak hours, at rates of around 5p per kWh :love:. It's a shame I can't fit something similar here but there's nowhere to site it and, anyway, the cost of installation would be about four times that in the UK, with charging costs five times those off-peak rates :eek:.

One issue which the Ampera specialist couldn't resolve was the problem with the tyre pressure sensor system, which automatically detected the new sensors, when I switched from the original wheels to the winter wheels but failed to work when they were switched back again. I have now re-fitted the winter wheels and the pressures are being read correctly again! So, the 'learning' system worked only once and now functions purely with the winter wheels.

However, on the plus side, the Continental winter tyres are so much smoother and quieter than the Michelin rubber. On good surfaces, running on battery power, I now only hear a little wind noise, nothing else! It feels as though the car is floating above the road, rather like the old Citroën cars with hydropneumatic suspension. If I am driving alongside another vehicle, I now only hear its tyres making a noise :D.

I wonder if the tpms can be reset as I still have one wheel not being sensed since replacing all four tyres. If I knew one sensor wasn't working I could replace it but after swapping the "faulty" wheel with another on the same side, the fault is still on the same corner!

That's a bit odd ! Although I'd think that the TPMS would reach far enough for the wheel positions not to reset straight away (took a few hours on mine)

Yes, it can be, according to the Ampera specialist I dealt with. That was his next suggestion but we first wanted to see whether the system would function correctly again with the change back to my winter tyres.


Bring on the ice and snow :).

I have just upgraded to the new TomTom GO 6200, from the 6100, mainly for the much faster processor, although the built-in Wi-Fi is also useful. Route calculations - and re-calculations - are now lightning fast, which means no more dithering when you have a route change and are approaching a junction. The traffic information on these devices is brilliant and worth the money alone. I'm looking forward to the new On Street Parking feature, too, which will be very interesting to test.

Please tell!

There isn't a button, Russ ;). He just said it would mean performing a complete re-boot of the system, which could be disconnecting the battery for a few minutes or it could be something else, he didn't say. Anyway, it will have to wait until I am back in the UK next year and the car is on the summer wheels again.

Thanks @Brett Sinclair
Will give my local dealer a call. At least they can't charge me for that but I guess will tell me nothing unless I take it in and as its just had its service I do not fancy that.

Sorted my faulty TPMS.
I purchased a Huf TPMS sensor from an Ebay seller who configured it for an Ampera.
Tyre company opened up the tyre and fitted the new sensor FOC.

The old one is undamaged but clearly not working for whatever reason. It took two trips for the system to sort itself out but all is hunky dory now.

The odd thing is that the car originally noted the front off side sensor was faulty.
I swapped the front and back tyres to double check but the fault stayed at the front.
When replacing the sensor I replaced the one in the now rear wheel but it has sorted itself out. Clever.

Obviously, it needs all four working for the system to reset.
