BMW 640D - First service cost?!

The hidden cost of dual clutch gearboxes. They needs loads of the most expensive grade oil every few years, so hopefully they don't explode one day.

Even if you buy the stuff yourself it isn't cheap.
What’s the service interval then ? Most dual clutch never need servicing. The BMW one doesn’t

It's part of a major service so every 3 years I think.

Even though some manufacturers say you never need to service them, you still do really. They only seem to care about it surviving the warranty period.

The ones I have any experience of are rated for "lifetime" with an advisory to service at 180K miles. Unless tracking regularly or something like that they shouldn't need anything like a regular service.

As much as it pains me to side with Nasher don't the VW DSG boxes have a service interval?

Googling it says 40K miles for DSG - but the last one I had a look at the manual said 180K :s (EDIT: though often the manuals aren't the most accurate for all the variants of models).
 
Not sure I'd want to leave the same oil in anything for 180k miles :D

Lot of modern big engine vehicles have 120, 140 or 180K miles or 5 years recommendations for various parts. Personally I'd be happier with more regular maintenance.

EDIT: Doing a bit more googling DSG6 apparently should be done 40K miles while DSG7 isn't serviceable rated for "life time" with just an inspection recommendation.

VW have claimed things are "lifetime" before and it turned out they weren't, like the timing chains. A big reason is probably to keep costs down for customers, not to keep the parts as healthy as possible :/

If you look at the much more reliable brands (like Lexus/Toyota and Honda) they still use 10k-12k service intervals. Being at the top for about the last 25 years they are probably the ones to listen to.

40k for the wet clutch variety, though Skoda tell me the interval on my newer 7sp wet clutch is 80k. The dry 7sp was 'lifetime' because the fluid isn't in contact with the clutches.

It's roughly a £250 service at a dealer so I'll be getting it done at 40k along with the normal service just for peace of mind.

Are you referring to the 2.0TSI tensioner fault?

The chains were fine, a design failure in the tensioner was what caused that problem and a revised tensioner sorts it out.

They weren't failing because chains should be replaced as a service item and VW pretended otherwise.

Their other engines had timing chain related issue too. Most famously the V8, which needed the engine removing to access it (££££).
 
Just facts. They aren't as well engineered as perceived.

Surely you've got to realise your own hypocrisy here?
You're criticising VW for a known fault with the timing chain tensioner which requires the engine to come out...once....to rectify, and that's 'poor engineering'.
Yet our own car, which according to the schedule, requires the engine out for a service item (plugs) gets a free pass because it "only needs doing every 60k miles" ?

Come on, Nasher. I understand being sceptical of the idea that a German badge automatically means solid design and engineering, but you sound like you're just desperate to bash them at any cost. And all you do is make yourself look like a Jap car fanboy. As Simon says (heh), it's a bit boring.
 
Well, you don't actually NEED to pull the engine out to change the spark plugs. That is just the official way. You can use a deep socket and a magnet :)
