MOT Trauma, and a glimpse of the Future

-
MX5 failed it's MOT yesterday on a weak handbrake, high emissions and the exhaust coming apart. I don't know what happened with the latter, it was alright beforehand but when it came back from the garage one of the bolts securing the front pipe to the de-cat pipe was missing completely. I put some new bolts on, and had a spare gasket, so that's sorted. Handbrake was adjustment again, I think I didn't do it right last time - seems very good now. Emissions... first suspect was the stock 02 sensor, which sits immediately behind the turbo. I've chopped it's wire and connected the analogue 1 output from the LC-1 instead. I'm going to order a new water temp sensor too, can't see any leaks around the manifold, hopefully that'll be enough.

I've bought some 320cc injectors for the next phase - Megasquirt! I'm putting together a list of all the bits I need, because it's DIY for me - no easy PnP solution (mostly because it's twice the price).
Look! Yes, an Imp - probably not airborne - is coming this way in 2009! It's not ever going to go wrong or fail an MOT, NOT EVER.

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 quite a lot

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 for BMW

BMW E39 diesel pump replacement

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 - it'
