Regular Maintenance and Repair Beyond the Warranty

www.smarttekinfo.com is the subscription site for all smart. Pretty much the smart equivalent to www.startekinfo.com for Mercedes.

$60, plus PDF Creator (PDF Forge) and a day’s worth in front of a computer and I can pretty much download a service manual for one vehicle specific for that VIN. You put all files in a folder and then you can search by topic title.

Unfortunately it is separate so I can’t just subscribe for a Mercedes and get access to smart, sadly. (Still have one of those to complete downloading).

Have you actually done what you are describing? How many different files will there be?

I have used ALLDATAdiy for a couple cars, but ALLDATA seems to have stopped updating this affordable service for DIY'ers - no Smart service information in it at all.

The desiccant is available from any MB parts seller. It's replacement every 2 years is trivial - easier than changing an air filter.

We will probably be dependent on the Mercedes dealer's proprietary "Star" syatem for some software resetting chores to some extent

The biggest concern I have is that in a crash that triggers an air bag or seat belt tensioner, an internal pyrofuse cuts the connection to the contactor relays in the battery pack. Which, becasue the dealers are required to treat the battery pack as a "black box" with "no serviceable parts inside", effectively totals the car (replacement battery packs are over $20,000). In the case of rollovers or collisions with the car while it is parked and charging, the pack is only software-disabled and in those cases it can be reset. Note that this design is strictly MB thing. Other EV's do not have such ovrly-draconian safety measures.

I am assuming for heat it has a toaster in the dash?
The AC compressor is electric - powered by the high voltage DC from the traction pack. Otherwise, it is the same as IC engine Smart's AC.

The heater uses a PTC ceramic heater element which is also powered by high voltage from the traction pack. Yes, use of the heater in winter has a major impact on the car's range.

All the other accessories are 12-volt and are identical to the IC engine Smart - including a 12 volt battery mounted under the footrest area of the passenger side seat. The battery is charged with DC-DC converter in the car's motor control unit.

Vacuum for the power brakes comes from a vacuum pump mounted in the engine compartment. You will hear it periodically turn on for a few seconds upon startup and after using the brakes several times - it is the noisiest thing in the car. There are no other vacuum-actuated components in the car.

The technical overview manual in Sokolff's the "sticky" post will probably answer other question you might have.

I'll check how many files when I get home. It is tedious so I can't do it in one sitting!

Diagnostics is more with the star/xentry machine pulling diagnostics codes, then suggesting course of action. But all the procedures, ie. battery replacement, are there.

I have for my ex-gasser, including some retrofit instructions...

Looks like 1190 files. (Looks like 1 I accidentally duplicated, or it's different somehow)!

Into 4th year of ED ownership and loving it!
Any issues?

Its for my wife, she drives 5 miles round trip to work. So the range doesnt worry me. Its plenty.

If I end up picking one up we should halvsies on a sub and rip it.

IMHO. I think if an airbag deploys it will be more expensive to fix the car then buy a new one.

Note that Evilution's author does seem to have, lets just say, an attitude about the ED:

https://www.evilution.co.uk/index.ph...=info&mod=1062
Ha Ha, I read that. I'll forgive him though, I bet he just get inundated with emails from people that are looking for information. It's OK though.

How come your car keeps recurring with the same problem?

Slightly confused here. If someone bumps the car a bit to hard while its parked, I have to tow it to MB to have it 'reset' or is there an option buried in the cars trip computer?

No issues, think of the ED motor as an "old school" Maytag.

There is a bit of a learning curve to get you beyond "range anxiety" and then it becomes a daily plug and play.

What's not to like about a full bodied temperature controlled electric go kart?
