I just got my car back from body shop and I floor it from a stop and it upshifts, does not spin wheels and no power off the line. What could be the problem? They replaced all radiators, oil cooler, heat exch, ac condenser, rad fan. Tranny fluid level ok. All vacuum hoses look ok. This has kleemann ecu/tcu so it normally lights up tires even with esp on.????????

The h/e cooling system needs to be bled, would be my idea.

However, there is another member with an SL65 who went through the exact same thing as you, car had to go to the body shop for some front end repair work, and never ran right afterwards. As I recall he never did get his car right, and last I heard was talking about just getting rid of it.

I hope you get to the bottom of the issue. But in my personal experience, cars are never the same after being in a wreck.

2003 S600

yes they had the dealer do that, I have replaced the intercooler hoses that go under the coil packs with 1inch clear hose so I can visually see if there is air in the lines. I thought it was the tps or throttle position sensor that kept making it upshifty but I replaced it and it did not fix it. If the tps goes bad the tcu and ecu are not on the same page and you might start off in 5th gear thus no power.

um if you car is an 03 doesnt that mean it is not the bi turbo model?

No 2003 and up = V12tt

I would check out the EGS .. sounds exactly how my car went when I changed the diff ratio. Does the gearbox shift gear normally once running does manual mode work etc?

I think it could be tranny problem. Load limiter active etc ...

2003 S600

egs? electronic gear selector?????? manual mode works, but cannot spin tires from a stop even in dyno mode. poor acceleration in low rpms, after 4000rpm boost is there and pulls good. I thought the shop put too much tranny fluid in, would it cause this. I told them not to flash ecu/tcu as I have Kleemann tune. I used to have huge boost starting at 3000rpm now it comes much later in rpm.

stevebez

hmmm...

That sounds like it could be quite a few things... no codes thrown at all?

Take it back to Kleemann... I doubt merc would try and get you your tune back.

P.S. try a tranny reset (aka sneaky ecu reset).

2003 S600

no codes thrown, did the ecu reset, even disconnected - battery overnight. no change. I still have M mode speedshift like the s65AMG so that means dealer did not flash tcu and I was told ecu was not flashed either.

stevebez

Have you had the car in reverse at all?

And, no disrepect, did you do the TCU reset (aka "sneaky ecu reset") correctly - i.e. wait a full 25-30 seconds...?

TopEndS62

I will agree that some cars don't DRIVE the same (mis-aligned frame, bent chasis etc)after a heavy collision, however an engine not responding the way it use to, is a different story(could be the bleeding process of the H/E as you mentioned)...

FWIW
My car was in the shop they changed hood, radiator support, radiator,and ac condenser, and my car still pulls hard...

stevebez

FWIW ... my MB tech told me the V12's are the only cars that need to be pressure bled for coolant, but the workshop would have known that.

2003 S600

i have reverse but did not try to do a burnout in reverse yet. could try. i did the reset long enough. i saw no air coming out or going thru intercooler lines. besides, i tested the car when it was cool outside and before intercoolers got warm. on a cool night intercoolers stay at about ambient temp in my car thanks to added capacity of my 1 inch intercooler hoses.

stevebez

Spark plugs / coil packs / fuel / injectors / compression test

Turbo bearings?

ECU / EGS ...?

I can't see it being much else.

2003 S600

I replaced spark plugs and ignition coils about a year ago, had misfires in 6 cylinders. All was ok after that. This damage was done by hitting a racoon.

MRAMG1

Okay, I answered this over on the W220 section but here we go. You say you had the IC system bleed, and that your clear tube confirms this. I say NO. If there is a bubble, aka air in the intercooler, it will NEVER clear itself, so that your tubing will NEVER show it, as it is the HIGHEST point in the system. If you have NO CEL's, I STILL say check here first.

Good luck

2003 S600

dealer bled ic with machine for 3hrs, so there should not be air in ic circuit.

MRAMG1

Well if you are 100% sure, as Stevebenz said, take it back to Kleenman.

Without ANY cels's to go by, ALL the air out of the IC system, and with NO mechanical damage to the engine. What else can you do

Good luck

The CL W215 & S class W220 Biturbo models came out in 2003 in US, Only the SL R230 Biturbo's came out later in 2004

I think I may have found the problem. With the air boxes off the right turbo spins slower than the left. When I turn off engine right one stops about 7 seconds before left one does. Maybe the bearing is bad. The shop did run my engine for a short time with no oil to get the car off the flatbed when it was towed to body shop. Oil cooler line broke off in accident. I was told it ran just to get it off the truck. Would that damage turbo?

stevebez

Only if they revved it pretty hard and built up some heat... for a 2-3 min idle I doubt it - unless it was marginal to start with. Normally turbo bearings have their own little reservoir to protect them when the motor is turned off and the turbo's are still spinning....

Does sounds like you need to have these bearings done anyway....

I would immediately contact your insurance company so, if the body shop guys did do engine damage, their or your insurance will cover the mechanical damage. Contact your dealership and have them do an inspection and let them know of the "dry run" with no oil and see what they say.

Why did they need to run the engine to get it off the truck? That does not sound right to me at all. Did they not feel like pushing the car into their body shop? Ask the towing company why that would ever be done or if they would ever start a car where they know the oil lines were damaged. They could have done tens of thousands of dollars in engine and turbo damage with no lubrication. Running an engine at any length of time without lubrication is an issue.

2003 S600

they ran the engine to raise the car, abc was dropped on all four wheels=need valve blocks i think. I noticed my gas milage is much worse now too and runs hotter. Maybe the running with no oil caused more friction in the engine parts causing more heat production and less gas milage and less hp. I cant even spin the tires from a stop even in dyno mode. I used to be able to spin tires with esp on without even trying.

2003 S600

do you think it could be a clogged cat? That would prevent spooling of turbo right?

2003 S600

my transmission fluid level is too high, I am siponing a quart out. Could that cause it to upshift and lose power off the line?
