stadleroux I took it in for its annual service on Monday and was told that there was a modification that had to be done to the starter-generator, so I told the guy that mine had already had its starter-generator moved over to align it with the other pulleys, but apparently MB have now issued an instruction for something additional to be done on a "you bring it in for any work and we add three hours' labour for this fix" basis.

Anyhow, they kept it there overnight, which meant that I had to get a taxi home Monday afternoon and walk to work yesterday morning - the joy of living less than 2.5 km from work! - but in the end there was one small part they didn't have, so they couldn't perform the fix anyway and it will have to go back at a time when they've received the part and it'll be more convenient for me.

I intend to ask them what exactly it is they'll be doing this time around that wasn't done in the first instance after my V-belt had broken.

Exactly! Except, if you turned the car off with the ignition you'd also turn the radio off.

We have horrifically low levels of driver compliance to traffic laws here, and in resistance to that I try to stay in the habit of actually coming to a stop at stop signs, amongst other things, but the mhd, in a sense, is discouraging that, if you don't like the idea of the engine turning off every couple of blocks, that is.

Don't like flicking it on and off for every possible instance where I may be stopping for shorter or longer periods... The switch isn't in a good location for doing that anyway.

The motor re-starts as soon as you release the brake pedal. This assures an immediate response and the start/stop function can be neutralized at any time with a switch on the console.

jwight I thought you can disable the stop/start feature....?

stadleroux The main issue with the mhd is that the starter-alternator's pulley, in it's original design, wasn't absolutely perfectly aligned with the other pulleys on the engine, causing it to wear prematurely and inevitably break. I was lucky in that mine broke either within a block of when it last started the engine or possibly even in the parking lot where I parked and where it wouldn't start again, so there was very little to no damage to the engine. The fix is to add a spacer or two before fitting the starter-alternator to move it over just a millimetre or two so that it's aligned. There was no recall for this, but I believe there should've been.

I use it most of the time, except when my AC or headlights are on, because then I believe the drain on the battery is too much, but I really can't say how much difference it makes to the fuel consumption. I just wish they'd set it to switch the engine off about 15 seconds or so after coming to a stop, because as it is now it switches off at every stop, even when you would like to start moving again right away. I would like it to work mainly during longer periods of being stationary, such as at traffic lights or in really heavy traffic jams.

But I read it on the internet . . .

At some point, "news" can become history unless of course it's 2 a.m. and someone is surfing SCoA . . .

But then again maybe the automotive press can pick this MHD 2007 news up in a Google search and include it along with the 453's all-new aluminum "tridion shell," as they write about the NY Auto Show?
