BAS ESP = no supercharger?
BAS ESP = no supercharger?
I pulled my SRT6 out of storage last weekend. The battery was dead and I had to boost it to start. I left it on a trickle charger for several days and then took it on a quick 80 mile errand. On the way home I noticed the BAS ESP indicator was solid "on" in the right side of the console display. I also had no supercharger, or at least it seemed to be running at partial power. I applied the brakes hard a couple times and nothing changed.
I decided to stop and top off with some fresh premium. When I started her the warning indicators were off and I had s/c again. I just checked the owner's manual and it cautions about the safety aspects of these indicators, but doesn't say anything about the s/c being disabled. Anybody ever experience this?
My concern is that I had the s/c intercooler and sensor replaced last fall before storing the car and it is now out of warranty. If this is a symptom of a second bad intercooler -- and not related to the BAS ESP -- then I have to look into a Bosch or Ford replacement.

Re: BAS ESP = no supercharger?
The only time my BAS/ESP light came on is when I "fried the supercharger internals". The dealer really could not explain to me in detail as of why or how.
During this time I had no working supercharger and it was in limp mode.
Does this light come on during multiple occasions? It must because I read others including you mentioning this light come on, but with similar/different symptoms.
See what the dealer has to say about it.

Re: BAS ESP = no supercharger?
My BAS and ESP lights have come on 2 times. On the dyno when I pulled fuse 17 and 18 and when I boiled the brake fluid at the track. Each time the lights went off after a restart. As far as the supercharger not working with the lights on, I don't have a clue.

Re: BAS ESP = no supercharger?
If I had to guess, I'd say you lost the input from the front steering angle sensors when the battery went dead. That problem cures itself when you turn the wheels lock-to-lock.
As far as the supercharger being inoperable, you got me. Might be some type of "safety programming " in the computer that puts the car into limp-in mode in case of a stability control problem.

Re: BAS ESP = no supercharger?
Thanks for all the answers. The problem did go away on my 2 mile drive home after I shut down for gas. I'll drive it some more this week to determine if the s/c (intercooler) is again unreliable. I'm reluctant to involve the dealer as it is now out of warranty. I really hope it is just some brilliant Mercedes programming that puts it in "limp" mode if it detects a ESP problem. I'll post an update after some more driving.
Re: BAS ESP = no supercharger?
It happened again on Friday. I noticed the BAS/ESP light and the absence of power at about the same time. I'll try the lock-to-lock reset this evening and take it for a little drive. Hopefully that resolves the problem otherwise I am facing some expense as the warranty is now over.
Re: BAS ESP = no supercharger?
This happened to me one time when i took the wire off to cancel out traction and all that jazz. I think it is just some saftey thing so you dont over heat the supercharger. When i reconnected the wire everything was fine. I tried it a couple more times and the same thing happened. I think after you do the reset you will be fine and no dealer will have to be involved.
Re: BAS ESP = no supercharger?
My BAS and ESP lights would come on when my car would go into "overtemp" for the supercharger system.
- Upgraded to a Johnson pump, same problem.
- Moved heat exchanger higher into the air flow, worked till outdoor temps went up.
- Copied and installed Woody's Super Cooler, no more BAS/ESP lights or overtemp problems!
