BMW 330d 3.0 2002 - Black smoke under hard acceleration, code 1028 - Fixed #

Posted by Jamie Lambert on April 7, 2011, 8:48 pm

Year of Manufacture *: 2002
Engine Size and Code *: 3.0
( Optional ) ECU Type: bosch edc 15c4
( Optional ) Scanner Used: kts
( Optional) Fault Codes: 1028 exhaust gas recirculation actuator (ARF)

Hi all
Got the above vehicle in at the moment. The vehicle black smokes under hard acceleration. One fault stored which also returns after a road test.
The fault code is 1028 exhaust gas recirculation actuator (ARF). Road tested vehicle and checked air mass readings which looked o.k, checked the egr pulse duty factor and that was operating o.k.
I checked the operation of the egr valve with a mityvac which was working o.k. There was a good vaccumn supply to the egr solenoid valve, also battery voltage at one side of the valve and a switching signal at the other. When i rev the engine stationary or drive the vhicle i never get any vaccumn to the egr valve, i would of thought i should do? I think the solenoid valve could be at fault. Any advice would be most gratefull.

Regards Jamie

Hi Jamie,
I have no knowledge of the system in question but I would have thought that a varying duty cycle should equal a varying vacuum to the actuator diaphragm. I reckon that if you supply permanent supply and earth then the valve should fully open, ie: 100% duty cycle.

Bryan.

Hi Bryan
Thanks for the reply, never thought of that. I will try that tomorrow to see if the solenoid is faulty.

Unlikely to be egr if it's under hard acceleration.
Possible boost leak maybe, not enough air for the fuel?
Or if it's the engine I'm thinking of, the crankcase breather when aged fails and causes black smoke under acceleration, they've always been a common fault and something I check first.

Hi

Had one a while ago that had a fault code for EGR.
MAF looked OK but vehicle was also under powered, the air filter had broken up and part blocked MAF.

Hi all
Thank you very much for all your replies. For the EGR fault i replaced the vaccumn solenoid valve which cured that. Checked the air filter which was fine. Customer wanted an oil service doing which involved changing the crankcase breather located on top of the rocker cover. On removing the breather it looked very blocked and rock hard. After putting everything back together took for a road test and everything was fine. Spoke to the customer a few days later and he said no black smoke and was fine. Thanks to everyone for their inputs.

Regards Jamie
