What unscheduled maintenance has been performed on your 335d?

I thought we could catalog 335d unscheduled maintenance performed and mileage performed at so we don't get surprised. I found reading the forum much more productive than talking to my service manager.

Maybe keep conversation to a min and just log mileage/symptom/fix/cost?

2010 335d
-20k: Fuel system and tank flush. Symptom: Delayed starting when "start button pressed" Diagnosis: bad fuel. No charge from BMW.
-25k: 4 wheel alignment. Symptom: Cupped rear tires. $200 to BMW
-25k: 4 New tires. Michelin Pilot Super Sports non-RTFs, 225/45/17. Symptom: Continentals worn. $710 to Discount Tire, $70 rebate from Michelin inbound.
-25k: Drivers side rear wheel bearing replacement. Symptom: Howling resonance starting @ 40mph, increasing in volume to 80mph. No charge from BMW.

Cystalized metering valve
A/C Belt Squeel

1. Two rear tires...ran over something that took a chuck out of the tread, 15K, $900
2. Windshield...Rock hit, 17K, $1400
3. Replaced rear indicator lights... had a malfunction, 17K, Warranty
4. The door seals...they were real squeaky, 5-6K, Warranty
5. Replace driver's side mirror...Squeaky when folding, 5-6K, Warranty

16K: SES light, DEF metering valve clogged. Fix: Removed valve, put into solution, functional check, reinstall! Warranty

22K: SES light, DEF system over pressure, blown fog light. Fix: Same as above, light R&R'd! Warranty

22.03K, 30min after 2nd incident above: SES light: TBD

Leaking LR tire with about 200 miles on the ODO. Plugged it myself.

SES Light - Replaced SCR Meter Valve at 34k - Warranty.

15k mi. AC belt squeal & replacement
18k mi. Wiring harness replaced (installation defect)

Otherwise it was trouble-free during my ownership.

Nada, 12,500 miles, almost due for first scheduled maintenance. Changed the oil at 5K miles on my dime.

Zach, great thread. It's good to see all the items that are specific to our M57 engines, exhaust/emissions and fuel systems.

DPF sensor recalibration and software update (17k) - Warranty
DPF replacement (clogged, regeneration wouldn't clear it out) - 55k - Emissions warranty
Gas pressure sensor hoses loose (not put on right after DPF replacement) 55k - Emissions warranty
Gas pressure sensor hoses replaced (work beyond use, causing SES) - 58k ($161)
Glow plugs and glow plug control unit causing SES (currently under review by BMWNA to see if they'll repair under warranty, since my car has 58k) - 58k (estimated cost - $1400)

Can't remember mileage, but here goes

DEF sensor and tank (multiple times in shop before outright replacement)
Accelerator positioner control (not sure if that is the correct name)
windshield replacement (something big hit it and it started to spider in just a couple of days)
tires (RFTs picked up nails - both right side tires - so replaced with non-RFT's and Tischer spare)
AC belt squeal (belt replacement - took several dealer visits to repair)

I think that is it - the disappointing thing about this car is the number of times it has been in the shop. I have 4 other cars (3 hondas and a Ford truck) and they hardly ever need to go in. This car has been in the shop more than all the other cars combined in the time I have leased it. My ten year old Honda S2000 just had the windshield washer motor replaced, and new radiator hoses. That is the first time any work has been done on that car other than routine maintenance. The other two Hondas (2005 Element and 2009 Fit) have had no work done on them whatsoever (other than routine maintenance). The truck has had some non-routine repairs - failed fuel injector, oil leak, EGR replacement - but that truck has 85,000 miles also - not 28,000 like the 335. I guess, I would say I had expected fewer trips to the dealership for non-routine repairs

I don't want to sound like I am whining - I love driving this car. My biggest complaint about this car is that it is a lease and limited to 15,000 miles per year, so I can't drive it every day.

I thought this was an interesting question and one that peaked my curiosity, but given the limited amount of time the BMW diesel has been available to us in the US and thus our limited experience with it, I thought it worthwhile to query diesel owners on the other side of the pond since they have been driving BMW diesels for a couple year longer. Some of the responses/reported problems are a little scary to think about.

Here is the thread.

1. Had passenger side Rear View Mirror replaced under warranty on third oil change. It was making a grinding sound when folding/opening.

2. Dealer forgot to refill DEF at second oil change so had to bring it back 2 days later.

That's it.

So far still loving every minute of driving the D.

That sounds exactly like mine.

When it was under warranty, I tried to have them fix the lumbar support on the driver's seat but the fix didnt do anything. And I really didnt expect them to get it right.

At 72k miles I am getting two codes P0400 and P0001, and the SES light has started coming on. The funny thing is that the SES light goes out after I fill the fuel tank.

The 0400 code has something to do with the EGR system, the 0001 code has to do with the Fuel Pressure Regulator. But the car drives fine so far.

Doesn't seem like that many issues reported. Is that really all, though?

While this isn't exactly a controlled sampling it seems like DEF (diesel exhaust fluid) issues are the most common issue specific to our ds.

Stugots mentioned an issue with glow plugs at 58k miles. Chris posted a link to similar issues on European ds, that included some glow-plug and turbo issues on higher mileage ds.

My d is running fatsticly, having exorcised a few demons in the past couple months. Terrific car, and I don't mean to be negative, but it would be great to keep the thread alive if anyone else wants to share thier d unsheduled maintenance experience?

Thanks all for the contributions so far.

Around 13k somehow got water pooling around battery which froze (was winter), ruined battery and engine would not start. Dealer said water was getting in through sunroof (was never noticeable) and replaced battery and a number of sunroof parts under warranty.

~4851 Miles: First DEF Warning due to unprimed punmp?
~4851 Miles: Reported to dealer that MPG figures reading low, still unresolved
~11000 Miles: AC Belt Squeal Issue

We're at 40k and have had a motor mount and glow plug replaced. I'm starting to think about extended warranties, but given the cost I may opt to retain the risk. It's a 30k per year, 99% highway car. My e46 went up to 130k until things started acting up. Currently I'm inclined to keep the $3-4k in my pocket but would love to hear more about what people are seeing in the 50-100k range. The D is my wife's so I don't have the level of familiarity that I have with my daily driver. Now that she has an automatic she has no interest in driving my car, so I rarely drive her's.

I'm just a youngster at 13K miles. Was a dealer service loaner we picked up at 8K miles. Not a single issue with the car thus far (the screw in the tire within the 1st week wasn't the cars fault). With the price of fuel lately seems like it was very good timing.

I did purcchase the extended warranty. Suppose to cover essentially everything that the original warranty covers, unlike the CPO warranty which is just drivetrain. My concern was not so much the drivetrain but rather all the electronics in the car. If an iDrive system needs to be replaced, I'm sure it's very pricy. And without it working if so equipted, you cannot use about half the car!

My son got our '00 E46 5-speed. Currently at 142K miles and no issues (except I wish he would clean it once in a while). But it was an over-maintained car.

Nada, nothing, zero, zilch. SES light came on once but after a spirited drive on the interestate it went out and has not come on. Had first service at 15K miles. Now at 18K miles.

Just turned 60,000. Only service out of ordinary was software reflash done at 150 miles right after I bought it.

Like Zach, the driver's side rear wheel bearing, replaced under warranty.

25K miles. Nothing yet. However, I can't seem to get the USB port in the glove compartment to recognize any of 3 USB drives I've tired. All have been formatted in either FAT32 or FAT16 (the one BMW sent me). That will be checked at the "free" BMW oil change this week.

My intercooler developed a leak and was replaced. They told me it the first one to fail stateside. Total time out of service was ten days.
