You are correct. If you completely remove/unplug the CEM, you probably don't need to remove the glove box.
I really wasn't up for messing with it though, so decided on the glove box method. I was also going to install my dash-cam, but half way into putting it all back together I forgot about it.

It must be pollen filter/ Dash cam season.

I changed my filter on Saturday, wound up doing both CEM disconnect and glove box removal since I hard wired one of these into the glove box


using this


I taped into fuse 45(?) for the existing cigarette lighter
then ran the factory cable for the Dash cam into the glove box and up the A-pillar while the trim was removed

Good work there Petey80, I have saved all the original pictures (thanks to Photobucket ) and I promise to replace them all with new image links, just not had time yet but it would be a great shame to lose the pics as the thread has become quite popular.

Just wondering if any one else had an srs airbag service urgent after doing this? I removed the glove box and disconnected the passenger airbag switch. However I forgot to disconnect the battery, which I think may be now causing the fault message.

Any one else face something similar?

I had that problem as I turned the ignition on whilst the glove box was out and the passenger airbag switch disconnected....

As mentioned, you'll need Vida or better to remove the message.

Thanks guys for the responses appreciated.

Any idea how much a main dealer charges to remove the error?

That will depend on the dealer I would say.

One could charge you the going rate for a diagnostic check and fault code read/erase.

One could be nice after you explain you were changing the pollen filter and forgot to plug it back in or remove the battery lead and do it for you for nothing.

It's a 5 minute job.

If you are in Dublin by any chance some day, Im happy to help you. Stealership will charge you probably for 1/2 hr of a workhour so apx 45/50 eur :/

Hi S. Unfortunately I don't have enough posts to respond to PM's.

Are you set up in Limerick?

Note; this is a horrible job, takes about an hour but I'd say you could do it in 30 mins next time around. I am 40 and probably not as agile as I used to be but some of the positions required to do this job will test your patience for sure. I've got quite a few minor cuts, saw elbows and a bruised hip! anyway, I'll soldier on....

First up, get this bit of carpet down in the PASSENGER foot well by pressing lightly in the centre of the two round 'popper' fixings:


This is what's up there, and in the way of the job:


This fuse holder/CEM unit needs to be lowered and pulled clear of its mounting bracket you release the unit with the two turn-buckle things. Here you can see where the unit can be lowered for changing fuses or pulled clear of the bracket:

The unit lowered down:

And the unit lowered (pull the carpeting down first) ignore the plastic trims I removed, that was me investigating the access:


Now you need to get the white bracket off (because it's in the way of the filter 'door') by undoing the two 13mm nuts using a socket on an extension bar, I just let the bracket fall down out of the way (careful not to drop the nuts though because they fall behind the carpet - twice in my case!):


Now get the pollen filter cover plate off, this should have 3 x 7mm? hex-head screws but mine only had one in the centre (dealers probably lost the others or gave up the will to live at this point so one it is) the cover pulls slightly towards the bulkhead as it has a 'tab' along its length:

Me reaching to get the screw out by hand so it didn't drop somewhere:


Now, wrestle the old filter out by pulling to the left - you'll have to squash it down to get it past the CEM etc and some bits of leaves and stuff will fall out - I used a long hoover nozzle to vacuum the bits up and got my finger in the empty filter casing to flick out for any bits.

The new one has to be offered 'up' the back of the bulkhead to clear the wiring looms and then brought down level with the filter box and pushed in - again the filter squashes down when you need which helps:



To compare, the old one has done about 14,000 miles in 17 months, that's 'if' it got changed at the previous service. Also note the direction of airflow is marked on the filter and must be fitted the correct way, for reference the air comes from the front of the car towards the Radio:


When you put the CEM/fuse holder back (remember to replace that white bracket) be careful as the wiring connectors can 'unhook' themselves one did it twice on me and was labelled 'cockpit 2' - just make sure the connectors are seated fully on both sides of the unit:


I was getting a slight smell each time I started the car and this has cleared. As I said it's a horrible job but manageable with simple tools and some patience. It is also possible to do without disconnecting the battery or unplugging the CEM which prevents possible faults later.

Would be possible to upload the photos?

They are missing on the thread.

Thanks,
