Some dealers are m friendly, but most of the time a occ WILL void warranty.

To be on the safe side I would do that. I will try to remember to ask my friend if that is true though next time I see him.

Of course the BMW tech is not going to say the 335 has any major problems to a customer. Take that all with more than a grain of salt.

My first 335 was a 10/06 build and definitely had an oil cooler. The fact that the "master tech" thinks none before 08 had an oil cooler, would raise a flag with me. I'm pretty sure all MT w/sport package 335s have oil coolers.

Some of you people need to familiarize yourself with the Magnuson-Moss Warranty Act, specifically Section 700.10, before making some generalized-sweeping statement like that.

The accessories around it may be failing, but the block itself is pretty much indestructible even when modded!

+1
if longevity is an issue for turbo applications -- most truck engines whether gas, diesel, or natural gas powered go for quite a bit longer than 200k

if you qualify as a certified BMW Tech -- you are required to understand several different engine/driveline platforms.. numerous electrical systems-- IBUS, MOSTbus technology-- there is a lot more to working on these cars than people give credit.

along with the techs investment of 50k-100k in tools for doing their job -- (yes that right, the dealer doesnt provide tools for techs, except for special tools/equipment from BMW) dont know many car owners that are truly committed to getting it right...

Mine is a E90 335i step 02/07 builddate and bought brand mew in May 07, and came without the oil cooler. 2 yrs later I told my SA that I was getting 270 in oil temp in city driving. The SA made a PUMA and retro my car with the oil cooler for free.

[techlogik]

Some master tech, he doesn't know shit obviously.

08/07 E92 335i....has oil cooler.

OP, thanks for posting! Unfortunately, there are some mis-statements in that post.

I am familiar with that act. While it was a great victory for people who mod, it doesn't seem to make much difference in real life application. It's very easy for BMW or any other manufacturer to find a way to blame whatever part it is on the failure.

Pay to play seems to be the biggest motto when modding your cars.

No offense, but IF you had any serious issues that could be related, that "note" would do you about as much good as a note from your mother. I SERIOUSLY doubt any here today, gone tomorrow SA has ANY authority to indemnify you from any liability for installing aftermarket parts with BMWUSA.....and I would have a hard time believing any GM or SM would approve of that. It's quite common in practice for them to turn a blind eye to SOME mods but no one with any authority would put it in writing. Think about it, is that supposed to make you golden with any dealership?

+1 MM act is totaly useless, BMW has the best lawyers and they will always win. Unless its something like new rims blew up your turbo lol but if it increases power or alters the engines functionality then they can void the warranty.

[MKE_M3]

my 07/2006 build has an oil cooler

[caradd]

Did he offer this for sale too?

good point -- better lube and less rpm's

now lets look a turbocharged application incorporates only one of those -- lower RPM -- but to balance it out it has less cylinders.

been to the airport lately -- see a huge string of containers being pulled by a little tractor looking thingy --- most of those are built by a company called TUG -- as in tug boat -- ie small boat pushes big boat ---

these Tugs are used almost 24hrs a day and are turbocharged 4cyl -- running on CNG -- granted they will peak out at about 3800rpm -- but doesnt the useable powerband on the N54 start well under 2000rpm? and useable torque peaks at well less than the 5000rpm mark..

if this car is not toyed with (tuned or otherwise) -- with the charge cooling provided through direct injection, high volumetric efficiency numbers, synthentic oil and the like -- how can you estimate the 100-150k number without further evidence (quantifiable -- i.e. not based on other engines -- but this engine alone) and proport that as a valid conclusion.

24hr a day -- CNG powered turbos that require very little maint. and are kept in service for a decade or more -- no extensive lube -- high operating temps -- stop and go traffic -- id say these little turbos are a value assest to a non stop industry .. no ?

I'm not sure I agree/believe all of the information this particular BMW master tech gave me below. But I did learn a few new things that lead me to feel more confident about keeping my 335i past the 100k mile extended warranty period.

What do you guys think?

Car Details:
2007 BMW E90 335i AT sport pkg (sport trans/suspension/seats/tires/wheels/steering wheel)
12/2006 production date
no iDrive
100k mile extended maintenance/warranty
45k total miles

Services Completed:
1. DMTL pump failed and replaced
2. radio firmware that randomly turned off rear speakers reflashed with new
3. loose module under passenger seat causing audible vibration at idle padded with felt and tightened
4. rear brakes causing audible tweeting at low speeds replaced
5. crimped exhaust hose causing audible plastic bottle crunching sound when shifting from 1st to 2nd gear replaced
6. completed all regular maintenance like spark plugs, cabin air filter, etc.

Forgiving this car has had the most annoying pissant problems of any car I've owned in my short life, BMW will not replace my fuel pump even after the recall nor add an oil cooler to my BMWNA confirmed "sport" model. Nor go half/half with me on the costs.

So, I caught up with a so called BMW master tech face to face at the local BMW dealer about the service issues above and the life expectancy of my 335i. This guy is NEVER at my dealer. It took 5 service appointments to finally nab him.

Information I Received from Him:

1. Oil Cooler I do not get an oil cooler for my 335i. No 335i prior to 2008~ came with the oil cooler. My car was not "skipped" on the sport model only oil cooler line. Owners were not used to seeing 275 oil temp readings so BMW changed the temperature gauge as well as adding the oil cooler.

2. Fuel Pump The fuel pump model # I have does not need replacing. The HPFP is an issue because detergents in USA gasoline are causing problems with certain model pumps. Europe does not have HPFP problems because they don't have as many detergents. The pump model # I have is good to go and is warrantied until 120k miles. (I don't have my pump model #. I only know the production date of my car is 12/2006)

3. Repair Issues The issues I have had to have repaired are not uncommon for any 3 series. However, the tweeting brakes seems to be a 335i only symptom due to the new/different brake designs.

4. Oil Catch Can Installing a non-BMW oil catch can will void my warranty. There is no harm in burning the bypass oil. No proof exists showing buildup of sludge on intake valves due to not having an oil catch can. 335i cars with 200k+ miles do not show sludge on the intake valves.

5. Life Expectancy None of the above issues/concerns shorten the life expectancy of my 335i. The 335i is built to withstand 200k+ miles just like any other 3 series when properly maintained and cared for. This particular BMW master tech has inspected/serviced several 335i cars with over 200k miles including at least one cross country traveler with 300k miles. None of these 200k+ mile 335i cars have needed any major repairs.

Your Master Tech is full of shit and either has NO idea what he's talking about...or he's blowing hot air up your ass.

[brentseay]

Thanks for the replies, guys. I'm thinking a lot of what he said was due to "Hey master tech, come tell this customer there's nothing wrong with his car so I (the service guy) can do the damn oil change and get him out of here."

Follow Ups:

1. From your replies, it appears only the manual or ZSP? sport pkg cars got the oil cooler prior to late 2007 when the AT got them. I missed out on that install timeframe apparently. Master tech calls the ball and he said "no". Not much else I can do.

2. BMW doesn't list my car as part of the HPFP recall. And since the master tech said "no" then I'm pretty much S.O.L. until something bad happens.

3. I don't care enough to push the OCC issue with BMW. However, I completely agree the OCC is necessary in turbo cars. The master tech said he had one in his own personal 335i. Go figure.

4. I agree 200k+ 335i cars are due to extensive highway miles. Any normal "335i" driving would produce a shorter lifespan. Which parts would show the wear and fail first? I have no clue.

Conclusion:

I think the 335i will be good for 100k+ drivetrain-trouble free miles or 200k miles if never driven hard. The car does/will have a few downfalls, though.

I only wish the people driving these 200k+ mile 335i cars would chime in.

Having some green beers. Happy St. Patrick's Day!

BS!
If this where true my warranty would have been voided since '07 on 2 different cars!

I don't necessarily disagree with what you are saying. However, and I'm no lawyer, but under the law of apparent authority, it may actually fly...although I'd hate to have to fight it. That basically says the SA was acting as an agent for the company and, since he answered the question, I should be able to rely on it. I'd also have this same dealer do the install.

Then again, I could be totally wrong....I'm not a lawyer.

Thanks for the info. My guess is I probably wouldn't have any issues until, of course, something happened and they were looking for a reason to void. Probably not worth the risk, but I'd sure like to have it installed.
