Sprintbooster problem

[DansSlk]

The ECU will hold most fault codes even if you interrupt its power supply.

To reset you have a few options.

1) Now that the SB has been removed the car will clear it automatically after X amount of drive cycles (its the amount of cycles put on the car not the distance that counts TBH)

2) Get an OBD2 compliant tester on it and see if it can find the fault but i wouldn't expect it to.

3) Get a DAS tester on it because this will find the fault and can clear it but its only found at dealers and good indy's, as for getting it done FOC thats up to the shop in question.

Thanks MBManInKEN
I agree that it seems the SB has knocked something out of sync.
Thanks DanSlk
Could you put a guess on the number of driving cycles to clear the CEL?

I liked the SB very much but if the CEL does not clear itself, I will have to pay to get it done and IMO the supplier should pay! the car was running perfectly before fitting.

Thanks again everyone for the assistance.

 

[DansSlk]

That really depends on the fault to be honest with you, i wouldn't like to hazard a guess.

Sent the SB back to CKS Performane on Sat.
Got a phone call on Monday from them, they had tested it on 2 different Mercedes and found no fault. The guy was curtious even though I expressed my doubts refitting the same SB.

They asked that I:

'After fitting, Turn ignition on and then off'
'Lock car and leave 10 - 15 minutes'
'Start car and drive'

Received the SB back late yesterday together with written confirmation of the phone instructions as to how to rectify the problem.

I did this and the car is now back to the original idle speed/smoothness - perfect!!!

But the CEL is still on and as I am going to have the track control arms replaced under warranty later today, I will ask to have the faulty codes? sorted.

Hopefully that will be the end of my SB problem, as I said in an earlier post the SB 'does what it says on the tin' and really transforms the car. I hope diagnostics can show the cause of the problem but I must say that in terms of 'smiles per miles' the SB one of the best products that I have ever bought.

I'll wait a few days to make sure that everythig remains OK and then phone CKS to bring them up to date and suggest that they may want to add the additional instructions to the original.

A big thanks again to everyone for their assistance - at one stage I thought about selling the Merc and buying a 'normal' car!!!

Glad I didn't

 

[DansSlk]

I'd bet thats a different unit because the instructions they gave you will do nothing.

Glad you got it working Scott !!!

So cynical

So cynical

I'd blame old age but i'm not that old.

Thanks everyone for your comments.

Went to the indie where I bought the car. He is about 50 miles from me and the car drove and idled perfectly.

They were using SnapOn diagnostics unit which made me a bit wary, anyway it found a fault code and the mechanic reset the fault. The CEL went out and has stayed that way so far. He wound not/could not tell me the fault code - anyway I,m happy.

DansSLK, I can understand where you are coming from and I too don't know why it worked but I assure you that it did.
Could you not also apply the same logic to a throttle reset - why does that work?
I am amazed also very but happy that it worked. Perhaps there are more resets that can be done using the ignition key/throttle/locking the car etc.?

 

[DansSlk]

throttle reset?

I'm not doubting what your saying so i have no doubts the unit is working totally fine now but i've been around long enough to know how people operate.

Hi DansSlk

Obviously I'm new to the Forum but if you do a Search using 'throttle reset' you will find around 49 posts on how to do it. I have also found it referred to as an ECU reset and gearbox reset

'but i've been around long enough to know how people operate'.

Are you referring to CKS, the mechanic at the indie where i bought the car or if not them then, who?

Thanks

Scott

I've personally no idea why these problems happened and I guess none of us will. I'm just glad you've got it all sorted. Hopfully the hassle you've had will soon be forgotten and you can enjoy the SB.
Owning an MB is a proud thing, and having one with a SB is even better!!:bannana: :bannana: :bannana:

Looking forward to swapping info on your next mod!!

Yeah i thought thats what you meant.

I have tested that personally with a DAS and so has BlackC55 and it has no effect on the settings.

I was referring to CKS with my comment because the procedure they gave you does nothing at all and since i find it unlikely it healed itself i am betting they replaced the unit.

Don't get me wrong I'm glad your happy with it and the CEL has been cleared thats great because now you can enjoy your car, i was just making a comment thats all.

 

[scottinbelfast]

I agree,

At last I am enjoying being a proud and happy mercedes owner!!

Hope it lasts.

DansSlk, I'll send you a pm
