2010 E70 X5 3.0d - Strange Noise

Post by Sm[]key » Sun May 22, 2022 10:46 pm

Could a dodgey MAF throw up this fault? I replaced the MAF when I changed the EGR valve. Still getting the following error codes:

4BB6 Air mass meter

4501 EGR deviation control

I didn't have the MAF fault prior to changing it, so going to get another one.

I pretty sure my vacuum hoses aren't blocked. Could the EGR cooler cause a problem? :headbang:

No, been too busy to sort it out unfortunately!

Now getting the fault - 4501 EGR deviation control - daily now after I've driven and then turn engine back on.

4BB6 Air mass meter comes up when I boot the car, got a refund for the MAF fault with change it soon for an OEM item.

Not sure what it could be, but vacuum pump is my next replacement plan?

One interesting observation was when I used the ISTA MAF test, I did this with previous MAF (don't think anything was wrong with it) and the current after market one I've had a refund for. The observation was when it holds mid range revs for a period, later in the test cycle the exhaust starts smoking excessively. Outside the car a strong smell of unburnt diesel. would be interesting to see if this is pointing to a known fault?

Replacement actuator didn't sort problem still got following error codes:

- 4501 - Exhaust gas recirculation control, control deviation
- 4BB6 - Air Mass Meter

Got all the above plus one below one time too all though this one hasn't repeated:

- 4507 - Exhaust gas recirculation control, control deviation

The first two repeat every time the engine is turned on...

I was hoping problem would go away but hasn't so need some help please.

I've already checked vacuum hoses during actuator change, cleaned the inlet manifold and changed the MAF although I've acknowledged this new part is defo faulty by doing the INPA tests. Also changed the EGR valve, still no change.

MOT is due in the coming months so need to sort soon, emission fault will come up....HELP

Isn't it perhaps time to consult with professionals, even a main dealer?

They don't come cheap I know, but maybe they can sort this out.
