It's officially Spring

-
Yes it is, because the MX5 is hitting the road tomorrow.  I've had a nice day hanging out in the garage fixing a few issues (loose exhaust clamp, trying and failing to get the twin exhausts to line up, touching in the paint, cleaning the interior and getting the Megasquirt to talk to my new laptop).  I don't actually enjoy the first 30 minutes of working on the car - it's usually cold, requires me to squirm about on the ground using muscles that have seized, I always get filthy, and my hands get tired very quickly, no doubt the result of mostly pushing a mouse about for a living.  But after that I'm fine.  Had Radio 4 on, and learnt a lot about New Zealand's laws on soft cheese and growing fruit trees in Cornwall.  All useful stuff.

I've got a nice steady idle now, after adjusting the fueling.  The 2 cells in the VE table where the engine sits around at idle had a pretty big difference (38 and 44), and watching it in real time I could see it was bouncing between them.  Setting them both to 40 gave a smooth idle, though it's rather rich (13ish).  There was a similar issue at 3000 rpm which I fixed (hopefully enough to pass the MOT emissions test later this month).

Adding bluetooth to a Mini with Harman Kardon audio

-

My R53 Cooper S has the unexpected bonus of the Harman Kardon premium audio system.  While it has impressive power and sound quality (once you discover the hidden settings ), it's firmly stuck in the past with just CD and analogue radio.  You can't change the head unit as the speakers are all wired to the 10-channel amp that lives in the boot, so new cables would need to be run from the head unit to each speaker, which would be an almighty faff. I wanted to add bluetooth so I could play my cheesy '80s music from Spotify, so bought a Grom BT3  which is a small module that plugs into the CD-changer port on the rear of the standard-fit Boost head unit.  It allows you to stream music from your mobile, and make/receive calls via the supplied microphone.  You can also buy another module that plugs into the Grom to provide DAB radio, USB, or iPod wired connections, I didn't bother with any of those, I just wanted Bananarama, loud. There are 2 versions of the Grom...

BMW E39 diesel pump replacement

-
Image
I replaced the fuel pump in the tank of the 530D yesterday.  It was quite fiddly and I couldn't find any useful guide on the internet, so I thought I'd create a quick outline of the procedure: Symptoms of failure : poor starting/cutting out when the fuel level falls to around a quarter of a tank. Cost : £42 from GSF , plus 2x 9mm petrol hose clips (the originals are not reusable). Procedure :  remove the rear seat base by pulling up sharply on it's front edge (there are a pair of spring clips holding it in place).  Beneath are 2 access panels to the tank, the pump is under the right-hand side one (behind the driver on a UK right-hand drive car).  Remove the cover and disconnect the 2 hose connections and the electrical plug (removed by pushing the locking clip sideways).  Unscrew the locking ring by gently rotating it with a hammer and chisel. Now slowly remove the fuel sender unit, noting it's orientation and how it slots into the pump assembly below ...

MINI tailgate hinge replacement

I replaced the snapped tailgate hinge on t'old MINI today, and it wasn't too bad a job.  The design is a bit crap and they tend to seize, and then break and attempt to bonk you on the head with the tailgate.  Didn't like that. The hinge is held on by a single nut but you need to partially drop the headlining to reach it.  To do this you need to: remove the tailgate seal remove the rear seats remove the rear side panel trim on the affected side This is all covered by some helpful folks in this YouTube video.  After this, you need to remove the white C-pillar trim; it's held in by 4 plastic tabs (2 top, 2 bottom), which fit into metal clips in the body.  It needs a sharp tug but there is a fair risk of breaking the tabs, but I got away with it. Now you should be able to gently pull down the headlining, to release the clip in the centre: That should give just enough clearance to get a 13mm socket onto the nut securing the hinge.  There is...
