If you have a multimeter things become a lot easier and simpler, but basically there are five wires coming from the phono leads. There is one common ground, and the other four wires are front left/back left/front right/back right.

I jumped the leads at the large connector by pushing some resistor wire down the crimp housing and wrapping in electrical tape (alsong with the unused phono leads) which was simple and easy. If I have any issues I'll go back and solder or crimp but it appears to have worked well.

In other general 996 news my trip computer tells me I've done 1000 miles after a trip to South Wales this weekend for a wedding.

Car was great on the motorway, although the back boxes are noisy when accelerating they are pretty quiet when cruising which is a good result. Out of interest did 27mpg including driving in and out of London and around South Wales which I think is pretty reasonable!

After thrashing the car about in Wales I'm more and more happy with the exhaust, sounds simply fantastic when you're on it, and the handling is spot on.

Only criticism is that the car does feel very crashy over expansion joints on the motorway or poor road surface. Is this common with other 996's or does it point to possibly tired dampers?

If you mean that section on the M25 near junction 10, yes it's probably a common problem, it's awful with Ohlins and their hard springs!

Haha! So glad it's not just me then Maldren! I had my (Ohlins equipped) C2 on that stretch of the M25 after New Year and dear god it was unpleasant! Everywhere else the Ohlins was fine (Not plush... not comfortable but fine) but on that ridged concrete of the m25!? Sheesh....

Oh and I too used to have an E36 Evo (In Techno Violet). Had it for about 10 years and loved it's analogue / you-get-yourself-into-trouble-and-you're-on-your-own nature. Great car but now I've had a couple of 911's I don't think I'd ever go back to it or probably any M3.

The ride is actually pretty good on standard (non-M030) suspension but it just seems like it's not very good under high speed impacts.

I know the (squeaky!) coffin arms need replacing - this is next on the to do list - so hopefully that will improve things somewhat and give me a good opportunity to check everything down there more closely.

Dagerous - I'm jealous - techno violet is my favourite E36 M3 colour! Really looks ace.

The spring rates are pretty high even for non M030... the rear ones are firmer than the front as they have to support the engine weight, so the front generally feels more supple than the rear.

Small post xmas update.

Having done 1200 miles in the last coupe of months I thought the car deserved a small xmas present:



I did say a small present. It turns out one of those is the perfect size to fit to your airbox to blank off the helmholtz resonator:



It is indeed a perfect fit. This supposedly frees up a bit more of an induction bark which is a nice thing to have and cheap and very easy to reverse mod! I've got a spare if anyone wants it...

I'll eventually get a 45 degree silicone hose to replace the existing OE part. You need a 80mm-90mm reducing bend according to my measurements:





But for now the standard part is back on.

I've also got myself a spare headlight to practice fitting a projector from an e90/91/92 which are readily available online secondhand on Ebay:



As good as the projector group buy look I'm a product designer with access to CAD and a 3D printer I can't resist a project like this. It's going pretty smoothly so far, I'm at the point where I need to buy a set of headlights for the actual build. If anyone has any getting dusty in a corner please let me know!

All I need to do now is get a plastic metallised shroud for the ugly bits of the projector and figure out how to incorporate sidelights. I'm fighting the temptation to add some LED halos...

Do you have any pics and dimensions of the E90 projector unit to see whether it would be an easy fit into a facelifted car? Are these E9* cars all fitted with Xenon lights or are the base models halogen?
thanks
Mike

I reckon these projectors would be a fair bit too big for the litronics. They're a 3" lens whereas I think the litronics is a 2.5" lens.

As far as I can see the litronics uses a halogen bulb below the projector for the flash (as per a lot of BMWs) and there isn't much space at all around the e9x projector in the 996 housing for squeezing that in.

Xenons were an option on e9x models but were fairly common and a lot are being broken at the moment. The same module is also used extensively on Audis, Jags, Merc you name it.

I just did some searches on ebay for "xenon lens" and a lot came up:

https://www.ebay.co.uk/sch/44240/i.html?_from=R40&_nkw=xenon+lens&LH_ItemCondition=4

Here's one for example:

Hi

Great car and am enjoying reading about your updates. I like how the cars are getting more and more "grown up" as it were. The 996 should keep you happy for a while, unless you just have to have more grunt.

I tinker with my 993 all the time, and its enough car for me.

All the best

Berni

The facelift Xenons are 3" dia and look similar to the e9* units. There are also some well priced Sinolyn units from China on Ebay but it's hard to identify the best solution, they have a BMW type units as well as a Hella replacement.

However, like the Retrofitlab lights, they don't have the option to switch from RHD for continental use.

Maldren - I'll take some pics and measurements tomorrow for you. Note however that these modules don't have the ability to swap between rhd and lhd as far as I can see.

Berni - thanks for your kind words. It's funny that while you're right, I am growing up through the cars - I'd say the 996 definitely feels closer to the 205 than the e46 m3, especially with the rs engine mounts, and it's all the better for it!

Like the updates and good for you for taking on the headlight up-grade. I must get my running thread started.

So the car has a "helmholtz resonator" ? Must check what is in the air box next time I am in the garage.

I looked in Halfords at the unit you fitted and it was a big surprise how much cheaper head units are than I remember and what a choice and stack of features, especially on-line.

The existing unit put up a bit of struggle to come out and whilst searching YouTube, I spotted a video of someone fitting the Continental unit and ended up getting one of those - very retro looking and a good sound I hope!

All being well, it will come before the weekend..

TV8 - The standard head unit was a real fight to get out. I had to put a screwdriver through the rings of the removal tools otherwise I think I would have severed a finger pulling before the bloody thing came out!

TBH with the head unit my favourite method has just been to go onto Ebay and buy a second hand unit with the appropriate colour lighting and the features I need. Especially now that most are mechless (ie. no cd player) if you go for a decent brand (Sony/Pioneer/Kenwood etc) they're extremely reliable. All I want to do is play music from my phone over the speakers, I'm no audiophile, and for £30 or whatever I paid for this unit it's been excellent.

Something that has recently been bothering me - does anyone have a method for tightening up the release cables for the front and rear boot lids? Mine nearly get to the end of their travel before they pop, I want to improve this situation if possible!

Successful Sunday afternoon fitting new coffin arms and track rod ends.
Everything came apart without much of a fight at all for which I am extremely grateful.





Inner bolt came out very easily, not corroded into the bush thankfully!



Meyle HD vs OE part. I know there was an issue with Meyle coffin arms being too long, but these looked exactly right. Clearly the casting isn't quite as good quality - the fillets are much tighter on the OE part - but the Meyle ones were £90 each including fixings which I reckon is a pretty great deal. Meyle parts were 150 grams heavier too - 1.5kg vs 1.35kg.

The ball joints were squeaking quite badly but there was no play I could feel, although they were a lot looser than the Meyle parts and the bushes were a lot softer. Could have probably got away with injecting some grease into the ball joints.

Drop links and tuning forks also seem to be in great condition.



Toe links had torn boots on both sides which is an MOT fail, replaced by TRW parts which I understand is the OE supplier? Need to get tracking done again now though...



Whole job only took about 3 hours so had some time for a wash and some other random jobs like adjusting the slightly wonky exhaust tips, forgot to take an after pic so here's a before of the car looking filthy!

Post work test drive confirmed I'd managed to remove the squeak from the front - it's now only squeaking from the rear! Very pleased with the work as I was anticipating this being a nightmare. The car really is very clean underneath - I count myself very lucky.

Looks like you did better than me... tried to do a tuning fork/diagonal arm yesterday which looked very straightforward. But I just could not for the life of me get the bolt through the coffin arm to turn. The angles involved with the car on an axle stand would not allow me to put enough pressure on the ratchet handle and I was keen not to damage the coffin arm bushes etc, back to the drawing board nooo

I did have to get out my extra massive breaker bar for the tuning fork to coffin arm bolt - they are absolutely huge and done up to 160NM which is massive.

I'm not sure I could have done it with just a ratchet. When it comes to undoing bolt on cars I tend to go straight to the absolute biggest lever I can get on the bolt and work from there. You could probably crack these off with the wheels on the ground which might be easier and safer.

Good plan... I will buy a breaker bar... the bolt looked in good condition and wasnt corroded so I’m obviously too puny!
