Starts soooo much better. Just need to figure out the longer crank time, but I haven't had to touch the throttle when starting since making the changes to the curves. I may lower the cranking RPM set point, it is at 399 right now. I think minimum is like 199. Lower may shorten the crank time, not sure.

399 is very high. When logging my abz with vagcom I was seeing 200-300 rpm on cranking, iirc.

Yeah, I think that is one of the reasons why it cranks so long before it tries to start, I'm going to set it for 199 (I think I read somewhere that there is a bug in one version that causes 199 to be 299) and see how it goes.

Still takes a while to crank. I asked my son what vehicle we should take to karate tonight (both he and I are students), the gray Q7 or the red car. He at first acted like he didn't care, then said the red car. I had set the crank RPM to 199 earlier this evening, and it really made no affect. It started up very nicely when we left karate a little over an hour later.

The coolant smell finally got to me, I ordered two new B4-V6 heater core lines that have the bleed screws in them. Not really looking forward to dumping the much coolant, but hey, at least I'll have non-leaky bleeders. There are a couple (?) small leaks in the top radiator hose setup, originally I had found a loose clamp, but there is still a drip somewhere. Not much room, so I'll have to try and peak with one of my inspection mirrors to track it down. Also need to put a dowty seal on the one PS hose adapter, slight leak from there.

I messed with the brakes last weekend, and figured out in my haste I moved bolt hole centers the wrong direction on the new caliper carriers (further apart vs closer together, dur...), and I need to add just a slight bit more thickness to the adapter. If I have sufficient wall thickness, I may switch to aluminum as these have turned out to be pretty beefy.

Just bought a set of Depo B4/80 H4 e-codes and will be putting LED headlamp "bulbs" in them to do two things: A) get a better light pattern when I do drive this at night and B) lessen the load on the alternator when the fans and PS pump are running. I'm also going to switch all lighting over to LED, I have a few random 1156 and 1157 bulbs in my toolbox that I'll use up in less critical areas, then get good bright ones for the signal lights.

Also need to figure out how to get a working horn in this thing, the bird and yelling only gets you so far in traffic...

I just ordered about $200 worth of LED bulbs...Yikes. But, almost half of that is for the head and fog lamps.

I'll be interested to see how the LED swap goes on the headlights/fogs.

Fogs are basically like lumens for like lumens (55W-ish equivalent, somewhere around 1200lm), so no driver needed. They are also yellow, which supposedly cuts through that stuff more easily. The headlamps are supposedly not only a whiter light, but slightly more lumens (1800 vs 1500 lumens). They do have a driver, it doesn't look like a huge box like some of them are, so it may fit inside the e-code housing itself. I may still have to leave the back cover off for cooling.

LED's and the new turn/hazard flasher supposedly start rolling in tomorrow. We'll see, USPS. Depo lights I think next week according to thEbay.

Flasher works great, the 1156 LED's I bought are too bright for the running light but super awesome the rear turns. I'm also replacing the 1157's I had laying around with something brighter as well as all 18 of the 2.1W 5mm wedge bulbs in the CHMSL. 194 wedges are brighter than stock for the rear corners. Hatch area festoon is very nice, lights up the whole area. Front 1157 turns are great too. I'll have to mess with the foglight switch to get them to come on w/out the headlamps, but they work, not sure how bright they are though! I have pictures on my phone but I'm not going to have time to upload tonight.

I have the D and P side map lights to swap yet, I have one in the housing but not in the car yet. Also have to do the rear map light, I think it is a festoon as well.

Eventually I'll replace all the IC bulbs, but I have a whole different "white" IC to install at some point (along with the matching gauge pod). So, now I wait for the e-codes to show up, got tracking info but it hasn't been scanned/entered into FedEx yet. The H4 LED's look nice, the driver is actually pretty small, may fit inside the housing w/out too much issue other than anchoring it.

Also, the 80lbf gas spring IS too stiff (gut, you were right), it's pushing the tensioner pulley such that the polyrib belt has a groove in it from the back side of the pulley. I have a 50lbf gas spring that will be here today, but I am not certain I will be able to get it installed until this weekend. I did order one slightly shorter so I have less to cut off and re-thread. The 80lbf spring was a mfer to get installed, so hopefully the 50lbf is much less so...

Can you share your LED vendor details and part numbers.
Also how well do these LEDs cooperate with the auto check build out warnings?
I relayed my headlights last year but never got around to addressing the bulb out warning.

Thanks, Jack

They do not cooperate with the autocheck, unfortunately. I dealt with the same with my relayed H1/H1's in my other CQ for years. I couldn't bring myself to cut those up to fit them in this CQ, they are pretty clean still even with ~40k miles on them.

I will get a list of what lights I'm using once they are all in and working. All were purchased on Amazon (I love Prime!).

Two pairs of exterior lights to go. Depos came in, forgot they have a 194 wedge city light. Also, the replacement 1157 rear brake/turn/running lights were supposed to be red but came in amber. Sending those back and got a new set coming.

On a quick test, the H4 LED's are pretty darn bright...I need to aim them, hopefully they don't scatter. The driver totally fits inside the housing and the bulb I picked has lots of room behind the cooling fan, so no need to leave the cover off (at least for now). Looking good so far.

I have not gotten to the three map lights yet. If it doesn't rain until later tonight, I'll work on aiming and swapping the map lights. Then a list of part numbers/manufacturers and pictures (I've taken several during the process).

Not sure if you know some of the drawbacks with using aftermarket LED kits is that they don't project light far enough compared to HID kits. Also they don't give off heat for the headlight lenses and may cause ice build up during the winter months. Here are some links if you want to read though them on HID vs. LED headlights. 1st comparison article and this one talks about laser headlights, 2nd comparison article which talks about LED not giving off heat for headlight lenses which can cause ice build up, 3rd article and 4th article.

I understand the heat thing, same thing happens to trucks with rear LED tails, I've been dealing with that for 10-15 years on the body-builder side of things. Not overly concerned about it, honestly but thank you (seriously). This is not a daily driver, and will more than likely be parked in the winter months unless I get another set of 16"+ wheels to fit over the brakes, and then mount snow tires. I have a his/her set of Q7's for daily driving...

I was after this more for the amp-draw reduction as a whole, and secondarily to improve the light quality around town.

I did actually not need the 194 white LED's for the headlamps, as the lamp plugs currently on the car are of the 3-wire variety and not the 4-wire like I have on 000292. So I cannot pick-up the marker/running light circuit at the current time. All LED's are working great, three domes swapped over, turn/stop now brighter, etc.

The fog lights are surprisingly bright for no voltage drivers, which with no drivers means they are also cheaper at around $20-25 for the pair versus around $60 for the H3's with voltage drivers. The headlamps are still the old USDOT units from a Cabrio with standard bulbs. They work fine, but I have been spoiled by the H1/H1 units in 00292 and the actually very good USDOT HID/adaptives in the Q7's.

The CHMSL assembly needs the bulb holes drilled out for the LED's to fit through, and even then it took some time to get every LED lined up. The part that attaches to the glass actually just slides off and you can drill and fit off the car.

All sourced from Amazon, quantities shown. Packages came in 2x, 5x and 10x depending on the piece. Prices were $5 to $50, again depending on the piece. If you can just buy what is on my list in those quantities (you can't, you will end up with extras), you will spend $150+. But really, you'll spend more like $200 to get everything.

2x 1156 red - turn - Zhol 2835 SMD
2x 67/1156 red - running - Zhol 2835 SMD
2x 1157 red - turning/brake - Luyed 3014 SMD
16x T5 wedge red - CHMSL - Partsam 2721 - Bought 20, had three bad out of the bag! I need to contact them to get replacements.
2x 53 - license plate (must be very short!) - Zhol 5630 SMD
2x 194 red wedge - corner marker - Yorkim 5th generation 5050 SMD
2x 1157 amber - running/turn - efoxcity 3014 SMD
2x H4 white - head lamp - Nineo 7200lm total, COB, 6000K
2x H3 yellow - fog lamp - Calais 1200lm, COB
2x festoon white - back seat dome, cargo area - Cutequeen 5730 SMD
2x 53/57/BA9 white - front seat map lights (and back seat map lights if equipped) - Luyed 3014 SMD
2x 194 wedge white - city lights (not hooked up yet, need a 4-pin headlamp plug) - Cutequeen 3528 SMD
1x CF14 / EP35 flasher - iJDMTOY
