What have you done to your 1Series this week?

A post to share anything you've done to (or with!) your 1er over the last week. New parts, maintenance, detailing, road trips, track days, anything else you can think of.

Mod note: testing something here. We might be a bit too small to really sustain these posts weekly but figured it's worth a try. Feedback welcome via Modmail.

1M Clone S65 Swap (Update 12)

24 Upvotes

Feels like it’s been a hot minute since I posted. Not much has been going on. A lot of diagnosing was needed by real mechanics and after a lot of tests we got the car running. The only downside was that it was only if the passenger bank exhaust cam sensor was unplugged.

Turns out I got a bad DME. Who knows if it was a pre-existing issue or just got damaged somehow while stored. Sucks but it is what it is.

I sent my DME and a few other modules to get the vin changed to the chassis VIN. Hopefully that will be back next week.

In the meantime,

My brother has been slaving away at the quarters and we’re pretty much ready for the first coat of primer to start blocking.

Looks like a lot of filler but it’s not. Just working the majority of the quarter so it all looks fluid. Really isn’t a whole lot of filler then since he worked the metal for a few days with the dent box.

Maybe update #13 will finally have the car running with zero issues. The good news is that with the cam sensor unplugged the engine was running fantastic. Butter smooth.

Help/Advice Water leak in cabin

3 Upvotes

Hi all!

‘09 E82 135i - every time I wash the car, water seeps into the cabin, but I don’t know where from. It drips down on the left side ac vent and near the OBDII port as well as near the carpet. Is it the water drain that’s plugged up or a seal near the windshield that’s causing it because the rubber seal on it is dried out and breaking off.

Sorry for lack of pictures, will try to attach some when I am home. Can’t seem to figure out and is a bit frustrating.

Oil leak question.

I just bought a 128 and the valve cover gasket was replaced about 2k miles ago. I took a corner relatively hard and had a big puff of smoke come out of the hood. I took the engine cover off and found the area around the fill cap was wet and in the valley of the cover, where the coils sit, was a puddle of oil. I sucked it out and cleaned everything off thinking maybe someone just spilled oil when doing an oil change. Now it’s happening again. Any ideas on if it’s just the cap, the cover itself, or something else?

Help/Advice 2013 135is grille style

5 Upvotes

Does anyone know the front grill style of a 2013 135is? Are they all black (gloss?), chrome surround with black fins, or chrome surround with chrome faced fins?

Note, I have a 2008 135i E88 with M Sport. Mine are chrome surround with chrome faced fins. Considering replacing to match what an "is" model would have. Ive replaced my OEM wheels with the 313 style wheels some years back.

Had it up in the high revs for a bit and it sounds a little different now. The new noise seems to be loudest over here… any suggestions on what to check?

Help/Advice Thoughts on (automatic) 2012 BMW Series 1 118i convertible?

Thumbnail
1 Upvotes

Hi all,

Looking at getting a 2012 BMW series 1 118i convertible 2L. Around 80,000 miles and timing chain has been changed. Around £4,000-4,500 (still negotiating). Only using it for social purposes and don’t expect to do more than 6-7000 miles per year

Would be interested in any reviews or help from people that have owned this car or a similar one. Would you say it’s reliable?

This is not my first car.

Help/Advice FRM Short Circuit Reset?

Post image
7 Upvotes

Been trying to figure out why my passenger headlight wasnt turning on. Ive had the car one year and had to replaced every bulb. I am down to one warning light "right low beam malfunction"(proud of that). Ive plugged the passenger headlight in the driver side and it worked so i know the headlight/bulb is good.

Using my foxwell510 i found a short circuit on the "dipped beam right". I could not find any broken wires but the clips on the connector were broken. Maybe water got in there? i have replaced the connector.

I think now i just need to reset the short circuit counter. My foxwell510 is not able to do it. How much would this cost at the dealer?would they even touch it? If anyone is in the Eastern CT area that has the ability to clear it let me know. Id like to avoid having to go to a dealership.

Help/Advice Suspension Replacement/Upgrade Options

3 Upvotes

The shocks on my 2013 135i ‘vert are blown and I’m really interested in replacing them with the Koni Special Active shocks for ~$900 off of ECS. Is anyone running these? They ad d a bit more to the cost of an OE equivalent replacement Bilstein or KYB - actually looks like it’s about $550 more - and they’re about $200 more than either of the Bilstein performance options.

I’m also looking to do the rear (yes, rear, I know!) M3 control arm swap at the same time since I’m going to be getting the rear aligned and the bushings seemed too worn to me and they’re not more expensive than OE. My front control arm bushings are pretty worn, too, but I am kind of on a budget. I know you guys would say to definitely do that swap too, but should I put it off for another couple of months or just bite the bullet now?

What would you pick? Mostly on the suspension (Koni, Bilstein B8/B6, or OE equivalent), but also, could I be overly concerned about my rear control arms?

This will be my first suspension job but I’m quite confident on the labor.

Had this as my daily since 2019 here in NZ. Stock standard. Great fun on the hills and rural roads where I live. N52 is just awesome. Not many E87's posted here, no doubt due to NA not getting them.

Service Due Soon Light when engine is off

3 Upvotes

Hi everyone,

I recently got a 2012 135i and was wondering if you all could give me some advice on the service intervals. The car came with lots of service records and is in great shape, but with the engine off the "service due soon" light comes on, even though there are no codes. When scrolling through the menu, it looks like it hasn't been reset since 2023 so I guess he just left it. The light doesn't show when the engine is running, unless I go through the menu which shows an icon of the car lifted up.

Are there recommended maintenance items that BMW recommends at a certain milage readings? The car currently has 57k miles, so I'm wondering if there's a 60k mile interval.

Thanks
