BMW E61 530 2005 - DPF system fault - Fixed #

Year of Manufacture *: 2005
Engine Size and Code *: 530
( Optional ) Scanner Used: modis/ launch
( Optional) Fault Codes: 480A,481A,4212,423,4242,4252.4262

Hi

I have this car with me at the moment, the DPF, turbo and breather have been changed over the last 6 weeks as all were faulty.

Its now down on power with the above codes. While I was driving it yesterday I noticed that the cooling temp on the motorway never passed 70c so I changed the thermostat. What I want to know is with 5 heater plugs faulty does this prevent regeneration from taking place like it does on the Ford 1.6 engines.

I am sorry but don't know All BMW codes off the top of my head and I would find descriptions helpful.

The glow plug issue clearly needs addressing next and is unlikely to be all plugs faulty so look for a common fault possibly control relay.

With regards to coolant temperature if still a problem look out for small thermostat on EGR cooler on some BMW models.

Hi Liam,

The DDE can prevent regeneration for certain faults, and i'm sure a significant number of faulty glow plugs is one that would. However, mine has one faulty plug and still regens so it has to be more than one!

As far as I know the system uses a combination of EGR & glow plug activation to increase combustion temperature during regen, so faulty plugs could be hampering this.

To regen the coolant has to be over 75 degrees, the pre-cat exhaust temp over 240 degrees, a minimum of 10ltrs of fuel in the tank and a road speed over 60kph.

Have you checked the exhaust temperature sensor (does it give a sensible engine off/on reading) and that the cat isn't blocked also?

Hi

Just an update, the small thermostat on the EGR cooler was faulty and had caused the dpf to block up again. Replaced thermostat and took
off dpf, cleaned it and then took it for a good spin. Two months on and it still going great
