HaHa! You want to use a Peugeot in this argument?!

At least it wasn't compared to a FIAT

Are you kidding? Peugeot diesels are found in other high level brands like Land Rover etc. They won LeMans with a diesel a few years back.

The technology of direct injection diesel as well as emissions equipment is not new.

That is why I suspect the fuel supply in NA as more the culprit, but its only a guess.

Best.

You really can't compare a race car that gets its engine torn down and rebuilt after every race with an everyday ride.

I guess your earlier statement about CBU in the peugeot negates the fuel quality statement. If CBU is happening in europe as well as here, then their higher cetane has little or nothing to do with cbu. It maybe happening at a slower rate, but it is happening.

Poor fuel quality is the boogeyman being pushed by the auto manufacturer's.

Peace.

Update: Got the car back yesterday. 4 injectors changed (since 2 are two weeks old). All 6 injectors tested before putting back in the car. Long road test (showed 35km on the odometer). 150km later, no codes so far.

How long for the DDE to give up?

Please let us know which manufacturers are pushing fuel quality as a cause of CBU. It would make an interesting read.

People on this forum have been told by BMW that poor fuel quality was the cause of their CBU. Some were even denied warranty coverage.

You still got a bit or it might tank. Just got my car back no DDE yet just a full reflash of the ecu. So stock everythang. I'll be driving it to see what's up and scan it tonight for shadow codes. Oops forgot to mention a puma case is open in regard to my ses light with injector 4.

My mileage 54k miles. Compared to your 93k ish miles lol

Seems I'm in for the same ride... CEL last week (less than a week after last dealer visit): injector 4 again. I did get the momentary loss of power 3 times before the CEL, all at cruising speed (almost decelerating) and on 3 different days. Will update once I get the car back... Got a 328d loaner in the meantime

[Roadrunner143]

Got the car back last Thursday. Injection system calibrations done remotely by BMW Canada and 2 days to do road tests. Cost to me: 20$ because they ran out of diesel... the 20$ is in the tank so I didn't complain!

Unrelated: I got the A6D1 code related to auxiliary waterpump numerous times. It seems it's been there for a while since the count is high:

I also get this code; it always comes back at one point after erasing all the codes. Something about short circuit on the auxiliary water pump. Haven't mentioned it yet to the dealer, as they probably won't do anything about it if there is no SES light or overheating.

Just got my 09 335d back from the shop. They did the walnut blast cleaning and within 2 days the CEL came back on, this time without the reduced power. Going to go in again next week. Arghhhh

My dealer filled my tank up for me after fixing my CBU. Cheap bastards.

My CEL came on the night I got it back after CBU cleaning. They replaced a few more things, but it took them another two weeks to figure it out.

I've been having fun with my 2011 335d since I picked it up in May 2014. In all fairness to BMW they have been doing the right thing ensuring I have a loaner at no cost to me and nothing out of pocket.

CPO is the best thing I did and I still have 2 years / 100k kms left on the CPO warranty. This is what my list of warranty claims looks like so far ($10k in parts and labor):
Cluster gauge
1 injector
6 injectors
1 injector and throttle body
DDE
Carbon cleaning (currently there)

I still enjoy driving the car and while it is a pain having to drop off the car I am still driving decent cars.
320 xi (meh)
328 xi (not bad)
328d xi (TDI with a BMW badge)
Mini Countryman (decent drive)

[LMT0286]

Wow dude that's crazy problems within like a 2 month window. hope shit gets resolved for ya

Welcome to the club. The 335d is not the most reliable car, you need to live close to the dealer and have free loaner. I have been there.

[lee4him]

^^^reliabilty is as good as any other make/model (IMO, better than most). Forums are a very small community of owners and in many cases owners with issues. You'll see the same type of reliability comments on the Mustang, 911, Cooper, Diesel truck and all other forums. There is a Lemon Law for a reason but that doesn't mean the entire line is a lemon.

6 months. Yes it's a lot but this is by far the best car I've owned and I drive a lot. 30k km per year. This is fun, powerful, and economical.

Previous cars:
87 cutlass (300k acquired at 200k)
01 z24 (crashed 60k)
04 Golf TDI (160k)
05 RX8 (20k sold with 140k)
09 Versa (160k)
11 Jeep Wrangler (current)

Loaners/rentals:
Mustang
Charger
Challenger
Prius
Plus many more I don't recall.

In fairness I've only had 2 issues with the car in the last 6 months.

Cluster gauge cruise control needle would not go to the right place. That was fixed immediately and only took 2 visits. One to diagnose and order the part. Second to install it.

The CEL with injector 2 adaptation error is the second issue and has been ongoing for 6 months. It takes a month at times for it to happen again. So can't fault them for the time. The number of visits is them following process. And you see that in the notes they include in the work order.

At this time I have had the carbon cleaning and already running a catch can. EGR block is in my near future with tuning following. As you can see I do plan on keeping this car post CPO.
