nice work @colb i try and get down sometime been feeling a bit under the weather with manflu.. we got a few things to sort when we meet up...

I did manage to get out in the 2.8 though today, and even dropped the roof for a run over the keepers trapper hat and scarf... to blow out the cobwebs.. been using the 2.8 mostly every day now and got to say its not that bad on fuel on a run with a light foot.. probably getting 25- 30 mpg it seems to be freeing up a bit now and the gearbox is loosening up a bit too.. i dont think it would hurt to give it another flush of gearbox oil i got 5 litres here...

@t-tony not sure about z4 yet, but if i get one its going to be early next year once i sell the two z3's.... probably go for a 2.5 though.. we have to see...

Well another fine day so out in the garage again with the Z4, took the rear arch liner out on the offside and gave it a good clean, painted the suspension arm then Waxoyled it all over, had to get the heatgun out to thin the Waxoyle down so I could brush it on. Hood drain on that side checkeds and found to be free of debris. Turned my attention to the front scuttle cover as I had previously poked the drain grommet up inside the wiper compartment when cleaning that out. Took the wiper arms off then removed the cover, only a few torx headed plastic screws, best leavered out with a screwdriver and long nose pliers, need to replace a couple. Found that the top retaining pins were all missing on the passenger side, all the slide fitting that the pins slot into were broken off, someone been in there before, history shows it had a windscreen replaced some years ago so probably done then by a clumsy fitter. not too bothered about that as the cover sits ok when all the other fasteners are done up. Retrived the drain grommet and found it still blocked by solid silt. Cleaned out and refitted then buttoned it all up. Fitted a pair of new wiper blades sourced from our local What shop that sells all manner of goods. Just under £3 for each blade and a straight fit to the arms, clear the screen very well and silent which couldnt be said for the old pair. Had to have a couple of attempts at refitting the arms to get them in a good place when at rest, first attempt the passenger side was hitting the scuttle cover so had to adjust that arm slightly higher to clear the scuttle. Parked it back on the drive and tucked the Z3 back in the garage. Thinking I may move the hood motor to the boot next. Will post some pictures when I do it.

Did you clean out the grease from the contacts on the motor whilst doing the spindles?

Hi Paul, no didn't have a look at the contacts on the motor, all working so didn't delve any deeper than just cleaning up the scuttle. Not aware of any problems, is there something I should know?

Something I get on mine at times, they park about 2" back up the screen.
I'll have to get the motor off one day.

Will be delving back in the scuttle and checking the motor out for that grease contamination on the copper contact plate, also ordered a spare relay to swap over in case it's duff. Had noticed some random stopping of the arms a little higher than normal, in fact they reached the bottom but carried on raising before they stopped, classic relay fault I deem from Internet research.

Couldn't wait had the wiper motor out and sure enough grease over the brass contact plate, all cleaned up with electrical contact cleaner and a light rub with some wet and dry paper, buttoned it back greased the arm pivot points and reinstalled.
Tested and all is well wipers park correctly now. Ace tip from the forum again.
Pulled the pollen filter last changed 2007 by the date on the filter. Quite black with dust, actually washed it in soapy water, its not a carbon impregnated one just a standard. Dry with a heat gun and reinstalled.
Whilst in there removed the fuse box to have a look behind in search of the EWS box, only one rectangular box behind there with a couple of relays. Is this the EWS, getting prepared to code some keys withan AK90 coding machine so neeed to pull the EWS to read the chip. Not yet explored under the steering wheel well, could be up there? Not found anything yet to point me in the right direction.

Installed a twin usb power socket with built in voltmeter over the weekend, drilled the mounting hole in the facia to the right of the heater knobs and spliced into the ignition controlled live at the radio, used the inner facia mounting screw that fits into the metal plate behind the facia for the earth. The power lead is fused seperately before the radio power splice.
Will post a picture when I next venture out.

Had a fiddle about with the AK90 coding machine that @handsomejackuk brought down today and a spare key he had with the right uncut blade for the Z4.Found and removed the EWS module hiding to the right under the steering wheel well. Had a go at reading it with the AK90 but kept getting no pin contact error messages even after cleaning the chip pins, will have another go at cleaning them and trying again.
Managed to sync the new key to get the remote locking working, took us a few attempts to sync both keys but triumphed in the end. At least I have another key that can be used to lock unlock, next is to get it cut and have another go at programming it with the AK90. Still waiting on the keys comming from China.

Key cut today at local independant locksmith shoe repairer, done in a duplicating milling key cut machine, tried it in the car outside, door and boot lock worked straight away, when in the ignition key wouldn't turn, ran the mill over the key again but still no joy in the ignition. No charge for the cutting as he wasn't happy that it only operated in the doors so waived the £9 he charges for cutting that type of key. Back home I had another fiddle with the key, found that jiggling the key it wouild actually work and turn. Decided it was a tad long at the tip so gave it a few strokes with a file, for good measure I gave the key a thin splash of GT50 and worked the key in and out. Eventually it began to work every time, did notice that if steering lock was set it required a little downward pressure on the wheel to take the strain off the lock internals, key worked every time.
I would have used some dry graphite dust as a lubruication which would have been better but the small amount of GT50 should be ok and not cause any gumming up of the internals.
Just got to get the AK90 Coding machine to read the EWS now so I can program the key.

One thing I have used many times in the past with fresh cut keys is to give them a rub on a wire wheel. It takes the ultra sharp edges off and usually makes them work fine.

Had a go with the AK90 coding machine @handsomejackuk loaned me, reads keys ok but got trouble reading the processor on the board using the clip on ribbon cable lead, keeps getting pin no touch which is a common problem with this unit by the look of it on the Web. Had a go at tracing the wires on this cable and found that one of the ten wires couldn't be traced from plug to the square processor socket, I suspect the cable is bad, have ordered a new AK90 machne for myself and will try with that. I would add that I have cleaned the coating off the processor legs, they are quite shiney and should be ok for making good connection, thats why I suspect a bad cable on Alans cable, he did have trouble reading his EWS and managed it only once. If the new AK90 still fails I may go for the alternative EWS Editor which negates the faff of connecting to the processor, that plugs onto the board and you use one probe to make contact to one of the solder joints on the board. Will update on the progress or lack of it when the AK90 arrives. Have ordered a used EWS module with same numbers as mine to play with and keep as a spare just in case. Still waiting for my key blanks to be delivered from the Far East.

Postman delivered the keys from China this morning ordered on the 9th November and in my hands on the 23rd.
Syncd them to the car and read the keys on @handsomejackuk AK90 reader, all looking good, just need to code them with a working AK which is on order then get the blades cut. One key is an upgrade to a folding blade, inserted the chip in the end of the key case furthest from the blade where there is a compartment for it, had to put it in the AK upside down to get it to read so will be interesting to see if the car will pick it up or it will have to be moved and fixed at the blade end. Can't do anything until its cut and able to be inserted in the ignition to test it. The second key is a Diamond shape which I know can be cut by my local man having already done one for me. Just the coding to the car to complete the job.

Decided to move the roof motor to the boot today, fully read up on the how to thread so it all began at 11:00. Stripping out the rear shelf was easy enough, those clips really ping off but recovered all four once the shelf was out. These clips were to haunt me later, what a difficult thing to put them back in.
Removed the left side rail and pulled it out, knack to doing that because of the hump underneath where it sits.
Peered in and could see the plastic motor cover, managed to pull the top of the casing off using a long bar and brute force, only one layer of tape around the top so looks like its had a replacement in the past. Bottom half with the motor in it was held quyite tight in the hole, just a bit of give in it. Had a go at sliding a hacksaw blade down the sides in an attempt to cut through the tie that was hoding it in, not sure I found the tie but with use of the long bar again on the metal part of the motor I manage to lift it up and the tie and the slot on the housing gave up. Pulled it up and out as far as I could but the cable and oil lines were being held down there by at least two further ties. A bit of pulling made these give up and lo and behold one shiny motor in the boot. No evidence of water but the warranty label on the motor housing suggests its a replacement.
Cable and lines arranged into two bundles and holes drilled in the plastic on the side rail so they were routed tidy. Motor secured in its new home with a tie using the bracket behind the carpet. Quick test of the hood operating made by putting a socket in the shelf cut out switch in the centre of the bulkhead, it worked ok in both directions. Some foam wrapped around the motor to deaden the sound and refit all the bits. This is where I ran into much trouble trying to replace the hinge clips that had pingged off so easily at the start of things. Hardly any room to get your hand and arm into the sides of the shelf and working blind to try and locate the clips from the top. Much swearing but managed to get the nearest clips back in on each side, gave up on the ones further back just couldnt get them in the right place. Had a look inside the car but access just as bad, may have another go when I have calmed down.
All bolted back to gether and ran a quick test, nothing, checked the cut out switch and shelf position, all appeared ok but raised the shelf and gave the switch a few clicks on and off then put the shelf in the down position again. Tried the roof and all ok up and down. Thinking the switch needs a slight tweek after everthing has been disturbed. Will check it another day.
Update: See next post for replacing the rear shelf clips, these need putting back to ensure the shelf is secured to operate the centre cut out switch, if the clips are left out the shelf can move up and not operate the cut out switch correctly.

Hats off to the guys who can do this in 40 mins I was finished at 6pm after all the faffing about with the clips, long day but jobs done now, will not be worrying about the motor ever drowning.

The saga of the rear shelf clips solved this morning in 10mins. To get the clips on at the front put the shelf in the up position then from inside the car reached around the seat backs and with the clip in my hand the correct way around felt along the top of the hinge plate and found the holes the clips go into, pressed them in and there was a satisfying click as they went home. Lowered and raised the shelf a couple of times to check operation of the cut out switch in the centre of the shelf and all looked good. Quick test of hood up and down and all worked fine. Motor a bit noisy now its in the boot will experiment with some foam to get the noise a bit more muffled.

New AK90+ machine arrived in the post today, plugged it in and pulled the EWS module from the car.
Read the only key I have followed by the new one I had cut last week. Turned my attention to reading the EWS first attempt with light pressure on the cable socket onto the processor chip resulted in no pin contact error message, applied quitre firm pressure on the socket and had another go. Success it read the EWS, promptly saved the Bin file and then set about coding the key. Key in the machine and hit the write key, pop up window appeared to choose what slot to code it into and selected the correct transponder box. Hit the write key and off it went followed by verification, success key coded. Carried out the same on the uncut flip key that has to be cut and that coded ok as well.
Popped the EWS back in the car and tried the new coded key, turned on ignition but nothing when turned to start, popped the original key in and checked that started ok, it did. Put the new coded key in and tried that again, this time it started the car, tried it a few times and it worked each time, seems I have sorted the extra keys now just the flip key to get cut and tried now.
Looks like my suspicion about @handsomejackuk's cable on his AK machine was at fault, will test mine out on his when my spare EWS turns up, don't want to tempt faith on mine. Spare cables are available so worth getting a new one if indeed the cable is toast.
The AK is available to visitors at the Zedshed Cymru if anyone wants to get a key coded just need to get a key and have it cut before a visit, any donations made will go on other tools and equipment for use in the Zedshed.
