it has full BM history Winny but I dont think they've done them. it would hurt at BM prices and given my loathing for Sytner I'd notice.

The BM manual says every 3rd oil chg apparently, so ignoring the run in swap these services were in late 2010 (guess), 2012 (serviced when i bought it from Knights) and the plugs should have been done in 2014 (Sytner). It's due again in June.

But I don't think they were done. If i can prove that i'll swap them whilst it's in bits

It does look great. That plastic crap cover ruins the view

Mine were done at 31k, luckily under the service pack cos it was a £900 service with the plugs and diff oil!

Need some of these

From what I understand, like a Bavarian S2, the intake is pretty good

i'll take some pics later

dare I say I'm missing the old fruits long legged ness

That surprises me. Plug change on my 04 STR is at 100K miles.

WinFreak

It's a good way of making money forcing people to do plugs every 30k miles, and there's 8 of the buggers.

it does seem faintly ridiculous but at £70 for the parts, fitted by my personal spanner chimp (me) i can live with it.

Fitted by a dealer charging £100+ph for a bloke working for £20ph to subsidise a ridiculous showroom designed to attract life for rent-a-twats and him needing to spend an hour removing stuff i have removed? no thanks.

checking here, add £340 to your service for plugs + air filter

Got the actuators off finally. They are a bugger to extract past a bundle of worrying wires

the replacement gears annoyed me, the half cogs are pinned too high on the shaft, this would result in the actuator arm being at least 2-3 mm further off the actuator body so I adjusted to match oem

I'll finish the rebuild tomorrow.

The boards look fine, no sign of overheat. I'll decide tomorrow but a refit and test seems sensible. Only 2hrs to remove so not a mare though fiddly.

so.. cogs out for the lads



this car has done c30k miles, you can see the very significant wear on the cogs 6th from the top down which are used on initial throttle (so most of the time)

I noticed that the spring is fairly strong holding this half cog and the actuator sits under tension for some reason, the arm operating 4 x throttle butterflys connects to the other end of the shaft through this cog, essentially there's a lot of weight going through this item. The other cogs dont show signs of wear on my car.

both replaced, hooked up to the car without errors but i've not cranked it over yet

WinFreak

I wonder if you'll notice any difference in how the throttle feels, go test it!

At least that cog came out before the teeth stripped completely - looks like the material is engineered to make the service dept some easy money. But then i'm paranoid.
