I can't say "I used" DMW. Most of stuff I tend to sort out myself and learn as I go.

I frequently meet the guy in the morning, at the corner shop- he goes to his work, I go to mine, we'll nod to each other, sometimes even comment on each others Volvo.

I did ask some advice few times. One of them was ETM issue where I was told to replace it, just like you.
As I said before- just cleaning it sorted it out.

And few years from last clean is a lot of time- I'd advise to do it again, shouldn't take long. Mind- mine is no-turbo, so access is probably easier. Anyway, on mine it takes about 30 minutes. All you needs a screwdriver for hose clips, 13(?)mm spanner for ETM body, cloth.

Other occasions with DMW were just quotations on fault readings, software update etc. I never really gotten to do them, but that's different story.

How do I find them? Just like any other garage- they're NOT charity. They're there to make money. Don't expect anything else and don't blame them. I don't.
