Hi guys just got a BMW 330d but i keep reading the DPF & EGR could end up destroying engine turbo etc that will clog everything eventually ,i had a 320d before this one had no DPF had that car 10 years with np problems any ideas will be appreciated thanks in advance .

Hi Ali

Welcome to the Forum

I hear a lot of talk about DPF/EGR issues in my experience normally from folks who drive the car almost into the ground normally short journeys so service intervals are extended (if it gets one) and then complain about the DPF/EGR. The others who talk about DPF/EGR issues are often selling a service that will hollow out your DPF then with some software tweaks get it running without warning lights. They don't tell you that if an MOT inspector picks it up it is an instant fail

On the other hand my own X5 3.0d has just past 135k with no issues my brother inlaws 540d estate has just passed 200k with no issues (both cars had the EGR recall early this year) Brother inlaws car is Chipped and way over 400hp and driven hard (which these engines love)

So reliability for the DPF and EGR will depend on what sort of driving you do and regular annual service as a minimum (I change oil at 5k intervals), if you do a lot of local short journeys at least once a month give it a good run at Motorway speeds

Hi Dave thank you very much for your reply very appricciated yes i do beleive in lower mile services also i wonder if my bmw had a recall or not i tried taking EGR off to clean but was stuck am guessing very caked in soot hence stuck i took out swirl flaps not like idea them falling in to engine but must admit lost bit of power on bottom end not had it mapped yet thanks again Dave .

Hi Ali

The emissions control system is kept clean by the action of the engine it's self. Two critical elements are filtered out Soot and Ash among many other particles, the soot is the one that clogs the EGR but is normally a sign of short journeys where the engine doesn't achieve full working temperature (note this is hotter than the heater starting to blow warm air) When full working temp is reached the car can measure soot content and if required begin a Regeneration cycle (note after around 2006 the engine management uses the Glo plugs to achieve regen temps, if they are not working no regen cycle) Once the regen is complete any resulting Ash is held in the DPF.

After 2006 the swirl flap design was improved and I have not heard of a fail or any falling into the engine

Considering the increase in the MOT and the likelihood of a fail if the examiner suspects any of the emission controls are tampered with or missing my personal preference is keep it as it was designed. My X5 3.0d 2009 has covered 135k and is as OEM build around town I get around 450 miles to a tank on Motorway trips closer to 600 miles to a tank. I change oil and filters at 5k with good quality BMW LLo4 compliant oil

The recent recall was for the EGR Cooler mine was tested and passed

Good luck with the hunt for someone to do the work in or near Billericay I am in sunny Sussex so not much local knowledge
