Need help on a 2000 X5 I just purchased.

[Mrathell]

I just purchased a 2000 X5 for a really good price because it has issues.

I changed the water pump.

It was throwing the codes P1421, P0300 & P0306

So I changed all of the spark plugs and the iginition coil for cylinder #6. The old spark plus had carbon build-up but nothing bad and no signs of oil on them.

I cleared the codes and I'm currently waiting for the CEL to come bacl on so I can see what codes are still there.

The X5 still idles rough, but once I put in in drive and start driving, it drives like a dream until you stop at a light and it rough idles again. It's not about to shut off but a rough idle.

When the car is cold, there is a loud ping/clank sound coming from the left rear of the engine. almost as though you are hitting a wrench against metal. It happens once every 10 to 15 seconds and then goes away after the engine warms up.

Would you guys suspect that there are more bad ignition coils or something else?

In the first picture there I circled a hard plastic hose that I have no idea what it plugs into. Any clues?

In the second picture, the x5 came without the 'false firewall' that seperates the engine compartment from the fresh air vents area. it was also missing the plastic piece that goes on top of that. Does anyone know the part numbers for those.

Thanks in advance.

Seriously, no one?

Is this one of those forums only for bragging about what you got?

Wow. With that kind of attitude you really think people will be running to help you? Especially after only a few hours after posting the question?

And, that being only your 3rd post in this forum?

I would say so given the only response was to my statement about the lack of response. I'll go to another forum and leave you guys to talk about how to clean your shinny new rims.

[cybervinn]

Yes, take your bad attitude and sense of entitlement and go beg somewhere else. Good Luck!

[Mrathell]

I already did. From what I can tell, you guys only know how to own an X5 but zero knowledge on repair. No regrets from me for leaving this forum. If I need to know what type of oil to shine my tires, I know exactly where to come.

This looks like a very early model E53 that it being a 2000 model. If you go to Xoutpost.com they have a E53 section on that forum. I think the problem here is that there are not many current owns of the E53 model.

I sold my last E53 back in late 2006.

People in this thread dosent know what your talking about. Since most people here owns the 2nd .
It would be best if you post at the e53 section 1999-2006.
