Rob, when are you coming out? I meant to ask Rich today, but we had our head deep inside RAR's CLS63 for most of the afternoon.

Soon. Alternator died on me Sat morning while on the freeway so I had it towed to the nearest MB dealer who still can't figure out how to fix it after 2 days. Already paid $280 for a new battery with install and they tried to charge me more for diagnostic time and I said no way. I'm ready to tow it out of there and back to Evosport since they had my car last. The dumbass MB tech at Penske Mercedes doesn't even know how to read the streaming data from the STS system which only takes 10 minutes max.

its crazy what little tech's know these days. Where would they be with out WISnet and STAR.

Ummm if you say your alternator died what diagnosis is needed? Replace the alternator. How do you know it is the alternator?

Blame the management, there are plenty of good techs out of work everywhere, but they lose their jobs to guys that are willing to work for dimes :\ They also could be confused because your car is so heavily modded and they are upset about that, who knows really.

Car got towed back to Evosport today. After battery was replaced the car cranks but won't start. They think the ECU or some other electrical problem.
Brad will take a look at in the morning. Funny that they test drove it before releasing the car to me and I drove it home that afternoon. Car had trouble starting that same night when I was going out to dinner. Next morning while driving on the freeway, the battery/alternator light came on a minute or two before the car just died. Right before the car died, the ESP light came on and I could not turn it off.

Nobody has a clue what could cause the battery to drain completely so fast. Even after the battery was replaced the car still won't start?

I can't wait to hear what Brad finds out tomorrow. I'm on the verge on leaving my car alone from this point forward and just sell my custom pullies to another Kleemannite. Both pullies for $500 shipped.

This is most likely due to low voltage on the battery. It messes with the ESP, In the same fashion the steering angle sensor does.

Here we go again.

Thanks for the tip but I've got a brand new battery in it from the dealer and it cranks but won't turn over. Mystery to everyone...Fuel pressure is OK so pump is working. Could it be the crank sensor? But Vadim changed that out last month!

And the answer was?

Exactly

AMGSC

I will have an answer tomorrow as Brad was backed up with 8 cars ahead of me and finally got to it late this afternoon.

Will have an answer on the root cause by tomorrow.

Worth the wait

I guess that two week window is kinda shot.....
Good luck.
Btw is it getting fuel and spark?

This isn't the first time...

See my other post. Car is ready for pickup and baseline re-dyno. Brad thinks the 427rwph on 6psi was probably low due to all the electrical and vacuum problems it had before being corrected by Evosport. More anxious to baseline on the track also using my new MTs.

first post says dyno comp for tuning, last post says evosport for tuning
