Just joined to provide some technical advice

[AUTOMAN]

I have owned my i3 Rex for a number of years I bought it after considerable research,it was not 6. months old possibly a ex demo vehicle and had 6k on the clock. Fortunately I was able to obtain a considerable amount of technical information which is invaluable.
The mileage is 37 k at the moment and I have serviced the vehicle as required and have found it very economical and reliable.
I have suffered the problem with the heater which came on just as the cold weather arrived.
I had purchased a fault code reader which indicated the heater unit was at fault, rather than purchase a second hand unit which may last for a short time I decided to purchase the unit from BMW £700 ???.
The actual fitting took about 1.5 hours bearing in mind it was the first time. I took care to bleed the system and the job was done.
I decided to investigate the unit which contained a very sophisticated controller and three heater elements. The unit is not repairable but the 3 heater elements were working so i deduced the fault was in the control unit.There is a thermostat which is replaceable if you can obtain the correct one ,it could provide a quick fix if it was at fault.

Further to my original blog a couple of years ago I decided to up grade my sat nav ,I had noticed certain areas were devoid of new developments.I purchased the sat nav upgrade but was a bit disappointed.
I have contacted BMW and have been given a method to review the upgrade. Have any members experienced any similar problems.

Unfortunately it seems to be a "feature" of that type of satnav. The company nominally responsible for the product (in this case BMW) simply buys in the data from one of a number of mapping data suppliers, and lowest cost will almost always be the most important factor.

I don't use my i3's satnav in many areas that change quickly, but I've used Garmin products all over the country, and with those, the latest map data is usually years out of date at the time that you download it to your nav device - on several occasions I've been warned about speed limit data that was relevant for road works that were completed four or more years previously.

Anecdotally, Waze is likely to be more up-to-date than products based only on bought-in data, but I confess I have no personal knowledge of that - I've never used it!
