Two days ago I did the Bank 2 solenoid replacement, took right under an hour and the pliers worked fine, no special tools were needed. Here's the frustrating part: the second time I started the car, everything initially sounded normal but then I went for a test drive and the car was extremely loud the whole time, and after 20 minutes the SES light returned! The exhaust sounds like a machine gun, and the change in the ashtray was vibrating like never before. I'm pushing 6 months now that I can't get rid of this light!!! The codes I'm getting are different then before:

54 - “Exhaust camshaft VANOS retard valve, Cyl #5-8”
72 - “Exhaust camshaft VANOS position control, Cyl #5-8”

Any ideas? It's a brand new oem vanos solenoid. Now it's not just my wife talking me into selling the beast. Now even my mechanic and all my good friends (except the one who has an M5) are agreeing that the car is not worth what I'm paying in maintainance and repairs every month.

Please help me out with this issue if you can and talk me out of parting with this wonderful car, if I spend another $2K and the SES doesn't disappear I won't have much of a choice but to give in and get something newer, though nothing really compares, I understand this better than anyone. I'm just not made of $

Sorry, can't offer any help. Just wanted to know how many miles you had when the Vanos codes starting coming up?

Ted,

When my beast had the blatty sound exhaust problem, the SES light would come on and off.

I used my Peake reader. Fault code 72: Vanos control solenoid Bank 2 came up.

I took it to the dealer to get 2nd opinion. Their GT-1 computer confirms it is a Vanos Control Solenoid going bad.

Part number: 11 36 7 831 450

Part removed and replaced and beast is back to full power, SES light is gone.

Sorry but that's as much as I know.

Have you tried the cam position sensor? I have yet to replace one, but everyone that I've read about with the same exhaust sound and symptoms as you replaced their CPS and solved their issue. Or am I on the wrong track.

I have never heard of any one succesfully changing out the vanos on the S62 with out using a GT1 to set the cams in the right position to get the vanos in place where they need to be.

You are going to continue to have problems unless you have someone with the right electronic tools to do the job.

Maybe you could post a quick synopsis of all the recent work you've attempted?

Maintenance only for hard parts (ie plugs, o2s, etc) as well as parts replaced
& codes.

I change my plugs all my fluids and filters myself using the shop I go too so I can have a lift and use there tools. If I have any codes they can diagnose them using the GT1. But codes only tell you where to look and does not totally diagnose the issue. A good experienced technician is good for diagnosing codes and major issues

I have a close relationship with the best shop in the South east and I have everything done there and have watched as they have done major repairs and it seems that the GT1 makes life alot easier when working on the S62. They have fixed 100's of M5's and never had anything come back not running right. Even my car when I had my left bank VANOS lock up at 105K they used the GT1 to disassemble the VANOS and to also install it you have to shut the engine down using the computer so that it sets the cams just at the right timing so that everything goes back in place perfect with out any adjustment. My car has 135,000 miles and runs perfect.

Peake Readers, LOL ouich

Too bad I did not have this info sooner Thunderbird but I appreciate your and everybody's feedback. I had a suspicion that that might be my problem and you are agreeing with it. I should have just let the dealer replace it to begin with, but I read 1 or 2 posts on here where individuals replaced a Vanos solenoid at home themselves without using any electronics and didn't mention any problems. What do you think would happen if I called up a dealership and asked them to calibrate the vanos for me, would they do it? Would they just hook it up to the GT-1 or would they have to go in and re-do the whole job of taking it out and putting it back in?

P.S. I have all 4 new CPS sensors replaced earlier this year and 2 new coil plugs and 2 new spark plugs.

Thanks!

I think its now time to take your beast to a specialist in order to end your frustration.

Either a very reputable shop that specializes on BMW's that has a GT-1 or a local stealer that other members recommend that charges fairly reasonable rates.

Tell the shop or the service manager/advisor the symptoms you are getting and the parts that you have already replaced.

Let them take it from there.

They will hook up a GT-1 and will tell you with fairly good certainty based on the GT-1 codes pulled and their service experience what is wrong with your beast and how much it will cost to fix.

You've got an awesome girfriend! But I'm sure you hear that all the time. Man, I've been trying to make an appointment to fix my car for 2 days, with 3 different dealersips, and the service has been so horrible I actually felt the need to write a letter to BMW USA. Wow. Still don't have an appt. for my car...

thanks for all the replies!

Ben Careful, do you think the stealership will have to do any actual labor on the car or will the entire repair take place via the computer?

You're not serious...

GT1 is a DIAGNOSTIC computer. It will allow a qualified technician to troubleshoot the VANOS, it will not in and of itself fix the VANOS.

This board member has this VANOS special tool for rent.
And he indicates he has the TIS for the procedure to do the work. :thumbsup:

If you are not going to rent the tool, it sounds like you can't fix it yourself.

Perhaps he would share the TIS with you so you can see what else needs to be done. If you can change the solenoid, I would guess you can adjust them with the proper tools and info. And if you can't, your indy should be able to with the tools and info.

At least the TIS might tell you how much time to expect the dealer to charge.

Regards,
Jerry

Let me make this clear, the GT-1 does not fix the problem it is a tool that allows you to not only see the exact codes that are stored in the ECU but will also shut off the engine in the vanos test mode so that the cams set in the corect position so you can release the VANOS Units properly and reinstall them properly. It does not tell you whats wrong or fix the problem but you are pretty much screwed if you are trying to do this with out one because you will never get the cams in place to reinstall, it will always be off timing until it is installed corectly with a GT-1.

Just took my car over to BMW of Arlington to calibrate the vanos with the GT-1. I told them exactly what I needed and what I didn't need. I asked them NOT to do a diagnostic or any kind of inspection, just to do what I asked as a paying customer no warranty necessary, which is correct my vanos solenoid install. Well they spent a good bit of time trying to tell me that their diagnostic (which they weren't supposed to do) told them that I need a new vanos unit, not just the solenoid. I explained to the service advisor and also to the service manager that the codes were thrown off by the improperly calibrated solenoid and that before I replaced it my codes were different but they wouldn't give up trying to sell that $3000 vanos bs on me! And they REFUSED to calibrate my solenoid no matter what I authorized or signed...telling me they were really afraid that they would be proven wrong!!

So I ended up paying $130 to get my keys reset to open all doors with one click and a lame car wash. I already called up Tischer BMW, the place I got my solenoid from, and they verbally agreed to do what I wanted after I told them the whole story about my vanos adventures. They set me up with an appt for tomorrow, I'll let you know what they say. Hopefully they don't try to run the same game on me. I understand it might be the vanos itself but I refuse to pay that much money when a new solenoid and a $100 calibration is all it might need.
