Help New BMW owner

Frogs422 · 09-09-2019, 02:27 PM

Hi Guys

Basically I bought my first BMW 320D 2008 N47 MSport back in april and everything was fine for the first month or so until I started getting the DPF warning light on. I managed to get it to do a regen on the way to our week away break and it was back to normal and that lasted for another month.

Then the DPF warning light starting on again but in this time my mum took very ill and was driving it around with this on for a good month until one day on the way to work my engine decided to run away with it self. It lasted a good 3 minutes until it eventually conked out (I'm aware what I should of done to stop this straight away but with having baby in the car my priority was getting her out as there was clouds of smoke etc)

So I got it transported back to my house and i've only just started looking at it now.

I've checked the oil and there is still plenty of oil in there and turns over freely, I've taken the in take off and gave her a start and after a few cranks she started straight back up and was pretty quite considering.

So after digging around BMW Facebook pages a lot of people are pointing towards the turbo so I've now taken the turbo off and it was full oil as expected, there is no play in the turbo itself but I will be sending this off to AET Turbos for a rebuild.

Also I will be doing a compression test on the engine just to be sure there is no bent valves etc.

So I'm guessing the blocked DPF has put stress on the turbo?

Which brings me to my next questions.

I travel about just under 13 miles a day to work (all round trip) at this point you are probably thinking well why did you by a diesel! Well I'm wondering the exact same thing to be honest, I rushed in buying it and I'm sort of stuck with it now.

So I need to get to the bottom off the DPF Issue, would my car even get to hot enough in 6 miles to do a automatic regen?

Is it worth just getting the DPF deleted with EGR etc for an easier life? I know it will fail MOT without it but I know a few people.

Sorry for the long story but I just wanted people to get to know whats happened.

My mate has a 2008 320d which blew the seals in the turbo due to a blocked DPF, so that could well be the cause of your turbos demise. You can take off the DPF and take it to a specialist who can clean it properly and test the flow rate on a proper rig afterwards. You should be left with a good DPF afterwards. Much cheaper than buying a replacement.

I would be checking that your car has no other fault codes. One of the main problems of DPF failures is often that the engine runs too cool, it needs to reach at least 75 degs C to start the regen process. When you have it up running read the codes and see what temp the engine gets to.

Once you have it up and running and all issues fixed, maybe you should think about factoring in a longer run ever week or couple of weeks to give the DPF a chance to clear itself out.

You shouldn't need to delete the DPF if the car is running well and without faults, its should be ok even at smaller mileages. Your car will stink without a DPF, despite being a bit of a pain in the arse at times, DPF's do actually work well at cutting the crap that comes out of our diesel cars. You can have it remapped and still make decent power with the DPF fitted too, despite what some dodgy tuners might tell you.

Just a note, make sure you drop the intercooler out and either replace it or clean it out as the chances are it'll be full of oil too.

Worth getting the fault codes read just incase there's any EGR or DPF specific sensor related faults as these can also inhibit regeneration.

no good getting it cleaned un til you find exactly why its blocking,,,stats are fist to be looked at,,needs to be getting to 88-95 degrees to be working properly

Morning new bmw e93 330i owner here. Love the car but it’s already developed faults. OBD scan showing P0139 P0159 P0305. Yesterday’s faults were P0175 P3284. Also found a spurious sheared round part in the engine bay. Don’t know how to add. Pic yet!
Anyone any ideas or can recommend a good BMW garage in West/South Yorkshire.
Thanks

75 Deg C is the minimum temp required by the ECU to start a regen.

It's probably worth having the DPF properly cleaned as the OP already has the turbo removed, so it would be easier to remove it. The car doing a regen is never going to clean the DPF as well as having it cleaned by a professional on a proper rig. I'm not talking about a dodgy back street garage spraying a high pressure hose through it and claiming its now clean.

I agree the cause needs to be found, which is probably the engine not running hot enough. There are other causes to be considered also. For the money I would be replacing both stats with BMW stats, don't bother with any other after market stats as you will just end up replacing them again when they fail early.

Your 6.5mi each way commute is probably pushing it to keep the DPF good. However all it should take is one 20mi ish trip every tank or so of fuel, to perform an active regen and everything be OK.

Sounds to me like you had a bad thermostat (there are 2!), or another (glow plug module, maybe) error which was preventing active regens. Alternatively you could have had any number of other problems (bad injector, bad turbo, bad maf, etc) which would cause poor combustion, and therefore deliver more soot to the DPF than it could burn off...

My thoughts would be to get the codes read immediately, log them, clear them (assuming all sensors are plugged in). If no red flags, get the turbo rebuilt or replaced, and DPF cleaned. Clean oil from the inlet tract. Fix any errors which could prevent DPF regen, etc. Go for a drive and monitor coolant temp to make sure thermostats are working as they should.

I totally understand your thoughts to get the baby out asap, but didn't you think it'd be safer to get the engine stopped first? I'm sure I would have panicked in that situation anyhow, so I'm really not having a dig...just a thought for next time (which there hopefully won't be!)

Maybe switch up to 10w40 oil now the engine has been 'run in'

Thank you for the reply.

I’ve taken it off the road for now so I can start work on her. I’ve had prices for a turbo rebuild £195-£295 and dpf to be taken apart and ultrasonic cleaned £200.

I’m going invest in a Carly to see what error codes come up. I’ve basically got a shopping list of parts and a check list.

Buy a diesel compression kit and see if there’s any bent valves etc.
Clean out intercooler etc going to get all pipes cleaned with dpf etc
Check Injectors

Turbo Rebuild Plus new gaskets and seals etc
DPF Clean
New Thermostats for EGR
Oil filter housing element & Gasket inc o-rings (Had a leak before main issue)

Then going to give her a service as well for good measure. Also advice taken on the oil 10w40.

Tambohamilton · 09-17-2019, 02:57 PM

Instead of carly, try deep obd. It's free, though not very intuitive. It communicates with all modules, so will show all error codes and clear them. Failing that, I think bimmergeeks protocol is better value for money. Either will work with a decent Bluetooth or cable adaptor.

Sounds like you're on it with the plan. Good luck! Fingers crossed for no internal damage...
