DAS/99clk430/intermittent starting - PeachParts Mercedes-Benz Forum

brianw · #1 12-19-2002, 11:30 AM

After replacing the battery and still having the car not start (engines turns over one time usually) I take it back to the shop and my mechanic believes the trouble lies with the DAS. His diagnostic computer doesn't read all systems and am wondering if there is some knowledge here to help solve this problem.

I was reading the search threads and I checked my smartkey for a rattle and it does have a small rattle. Could it just be the key? I only have one.

Thank you for your time.

Take your wallet key ( one without transponder) and use it for a week or so, if it starts without any problems get another key. The chips do come loose due to dropping them. You will need to read on how to program the new key if your dealer wont do it for you

Thank you euro 287, but the 99 doesn't have the mechanical type key to start the car. Only to lock compartments individually. I'm going to try replacing the battery, then ordering a new key.

Any other ideas on the driver authorization system?

There should be a thin black key that resembles the smart key, but is 1/4 the thickness. All cars with smart key came with them.

Your car should have come with two SmartKeys of "full size" and one "flat key" which is a smaller thin plastic key that has a removable small metal blade for opening the door and a transponder for starting the car.

A common failure with SmartKey cars seems to be the key itself, but my C230 had the EIS go bad. If the problem persists with a new key or your flat key, then you'll probably have to replace the EIS. Otherwise, the key is at fault.

Is the car under warranty?

Thank you for the replies gentlemen!

I just bought the car used and there is no remaining warranty and no extra smart key or flat key. He only had the one key left. I did replace the two small batteries in the key itself and am going to order an extra key to see if that resolves the problem. Otherwise I'll look into the EIS.

Thanks again for taking the time to reply as I know people are very busy and this board moves quite fast these days! It is greatly appreciated!

You should know that those words are really appreciated, and don't go unnoticed around here.

You should get more keys for the car. They are fairly expensive, but the flat key is great for keeping in your wallet, and a spare key is required in case you lose your primary key. It's not an easy task to get a new key, so having a spare is not an option.

Also, when at the dealer, make sure they delete the two missing keys from the computer. Last thing you want is a key for your car floating around out there somewhere.

And I envy your CLK430. It's handsdown one of my favorite cars. However, in my neck-of-the-woods, they are $80K+ and use WAY too much of our $3.85 a gallon premium gas...

Well John, if I could give back only a small portion of what the members of this board have given me in the way of car knowledge, car care, maintenance items and "what not to buy" type of information, I'd be proud!

I have very little in the way of automotive knowledge and this is such a valuable resource that one cannot simply get by reading reference material. And beyond that, the amount of time and energy everyone puts into this board is what makes it so great.

I was in the dealership oscillating between buying a new or used clk and was handed a new Benzo Magazine. During my wait I began reading it and wanted to check the publisher and contributing writers. Sure enough Donnie Drummonds and Lee Scheeler were in black and white. Just another commentary on the caliber of people here and to think about all the time people give back to this board in the midst of very busy lives. Not just the automotive community but the overall intellect of this place is great. The quality of people here really make this place enjoyable to visit.

So if my shortfall is mechanical knowledge, let it not be my awareness, appreciation and thankfulness to the people who make this place so great. With that being said...Thank you all!

Oh yes, I'll go order me extra keys now!

I received a new key ($155.94 USD w/blade key) and the car still has the "turn over once, then stop" problem.

So, after searching the web for TSB's for the clk line I came across an article from Consumerguide.com which says: "The starter stops running before the engine is running due to lack of grease on the starter drive gear. (1998)"

I hope this resolves the issue and will keep you posted. I'm having the car serviced on Tuesday and will have the starter "greased" then.

I hope that is the solution!

Thanks again and take care,
Brian W.

Hi Brian, do you hear a chirping/squeaking noise during cranking? If so, the ring gear lube is what you need. If that's not the problem and you can access codes from ME-SFI you may find a code for "Start enable from DAS not sent"(P1570). This means that the Drive Authorization System(DAS) interrupted the start attempt. As previously stated, a faulty key or a bad EIS(less likely) could be to blame.

ILUVMILS,

Yes I do hear the chirping/squeaking sound at startup. I will have the ring gear lubed next Wednesday! Thank you!

I did have my mechanic lube the starter gear during my last service and have had no problems thusfar...only 1.5 days. But will have this "ring gear" checked none the less.

Thanks again!
