When Engineers Get Bored...

...they design things like electronic parking brakes, where through the miracle of technology, they replace perhaps $250 worth of handles/pedals and cables with well over $1000 worth of electrical switches, control units, wiring, and servo motors. That is, of course, if they don't also use cables, as in models like the 2010 Subaru Outback.

2009 VW Tiguan parking brake control switch (located in centre console)

Theoretically, an electric parking brake does allow certain things, such as automatic application when the vehicle is placed in park - none that I'm aware of will do that, even if many will release when the throttle is pressed. Auto Hold, as seen here, will hold the vehicle when you come to a stop (until you press the throttle) so you don't have to stay on the brake in traffic, as well as preventing roll-back on inclines. Didn't a manual handbrake also do those things?

Using a switch instead of a handle or lever also potentially frees up space in the centre console which... ...wait a second, the Tiguan's switch is where the hand lever would go. No space gained there.

Well, you do get some added coin storage, I guess, but look at how much coffee has already found its way into the switch due to the proximity to the cupholders. This would, at worst, make a handbrake handle sticky, but it could potentially spell intermittent operation or even death for these two switches, which are not likely cheap to replace.

Speaking of not cheap, when the time comes to replace the rear pads (with or without the rotors), you now need to command the parking brake servo motors open, which requires either a VW-capable bi-directional scan tool, or a specialized, purpose-specific control device, like the one seen below. There is no other way to do the job properly, and you can bet the shop's added costs in equipment will be factored into the job.

We won't even get into Volkswagen's corporate fascination with unusual fastener drive systems, such as the "triple square drive" bolts that retain the brake caliper bracket (and, it appears, the wheel bearing assembly too). Thanks for making me spend even more on yet another set of special sockets - they'll complement the metric Allen drive set that already gathers dust in my toolbox between German car repair jobs...

Jackass Award - Proof That a Mechanic Slept with an Engineer's Wife...

2008 Saturn Vue 3.6 L V6, as seen from below - front is at the top. (See the filter?)

Understandably, service access is not always the top priority when designing a new vehicle; cost and relative ease of production often trump it. I get that.

I also sympathize with the engineers somewhat as they don't always have the big picture, having to design a door hinge or a heater or whatever without specific knowledge of what's around it beyond basic dimensions. This same component - this engine, in this case - also often has to be able to fit into multiple vehicles. That's reality. I get that too.

However, what I don't get, and can't deal with, is stupidity when it comes to stuff that has to be serviced regularly, and oil changes are about the most regular service any vehicle will ever require. An oil filter isn't like a hydraulic valve lifter that will probably last the lifetime of the car. It will be replaced at a pre-determined interval, as many as 50 times in the 250,000+ kilometer life expectancy of the average private vehicle. We're talking several times a year.

So why would anyone put the oil filter in a location that almost guarantees that it will make a mess of the A/C compressor, subframe, and probably the technician? It's an awkward extraction at best.

More critically, why would anybody put it within millimetres of a catalytic converter that's designed to get several hundred degrees of temperature within a minute or so of the vehicle running, so as to virtually ensure that whatever poor sap has to change it will receive severe burns?

You can't tell me that this filter's location didn't receive some amount of consideration, yet there it is. Someone deserves a career of designing glovebox hinges for this one.

It's easy to criticise: what could they have done differently? At the minimum, they could have angled the converter away from the filter - there's clearly space to do so. They could also have made it possible to access it from above (it isn't), or have provided an opening or door in the air deflector to get at it from in front of the subframe (there's almost space for that with this same engine in the larger Lambda models {GMC Acadia, etc.}). Not as preferable, but it could also have been integrated into the oil pan as was the case on the earlier 3.5 litre DOHC Oldsmobile V6.

While GM is by no means alone in doing things like this (everyone does them to some extent), something this dumb feels like it could only be malicious. Proof that a mechanic slept with an engineer's wife...

Credit Where Credit is Due Department

...thanks, Janis.

A tip of the hat must go to Mercedes-Benz, or at least their advertising department, for coming up with this impossible-to-miss, skyscraper-sized poster advert, located immediately across the street from Cobo Hall, site of the 2011 Detroit Auto Show.


It's a clear thumb of the nose to Porsche, who returned to Detroit after a several year hiatus. This has shades of the Audi vs. BMW PR war that's been going on for several years (my favourite - a wall-sized ad for BMWs on a billboard above a Hong Kong Audi dealership). Who say the Germans lack passion?
