I took the battery off for three weeks... Yesterday I replaced it... Started the engine... The car was on a limp mode on "D"... Not changing gears... Moved to triptonic mode... Changed the gears manually... The gears were changing as usual... 1-2-3-4-5... Stoped the engine... Started with the same problem... Not changing gears on "D"... After several trials it started to work as usual... First with no power at the beginning... For exemple on a traffic light... Later started to react normally... After half an hour of drive everything became normal... Today the problem came back... I turned on the car and moved gear on D just for some inches I felt a jerking and sound (tock) from under the car (transmission or differential area)... Engine in limp mode and not changing gears... I turned off... Run again trying the triptonic as in my previous post going up to 5th then to D... Started to react normally... Went to the dealer... The codes that the service provided me are 97, 132 and 135.

My SLK is a European 1999 with a 2000 cc non-compressed engine (111.946) and an automatic gearbox (722.602)... 95.000 km on the counter... I don't know if the above mentionned codes are different from the UK codes... Based on the above mentioned error codes can anyone help me to diagnose the problem..?
What was the solution in your case..? What might have been the problem..? Something related to the memory of the automatic gear box..? Maybe the memory was erased because of the absence of the main battery..?

Any ideas..?

I think the fault code list in the link would apply, but it is general for all 1996 and newer MB's so sometimes the title of the code doesnt match perfectly with the part on the SLK in fault:

I couldnt find a code 97 though, is there a digit missing on that code? Maybe my eyesight is failing if someone else sees code 97. 132 and 135 codes are related to the 02 sensor. The dealer who supplied the fault codes to you didn't comment on what the codes were?

My car is a European SLK 200 (136 HP)... The following is the interpretation of the codes from a different forum...
97 (001): This actually is not a faulty code. It means no fault stored.
132 (036): CAN: Communication from engine management faulty or engine temperature implausible
135 (039): CAN: Engine management communication faulty
I don't know is the US and European codes are different...
Can these codes ease the solution of my problem..?

Thanks Leapyfish. I havent read every entry in the thread you supplied, but post 48 in that thread goes to a very complete listing of the codes and includes some troubleshooting help on the more common codes.

Solutions to all my problems...

My problems were: http://www.slkworld.com/slk-r170-general-discussion/14602-dead-battery-auto-gearbox-problem.html#post158748
Solutions...
I changed the front “donut” of the propshaft... The one which just after the gearbox... No more jerking...
I changed the battery (60AH/540) with a more powerful one (74AH/680)...
Changed the oil and the filter of the gearbox... Believe me it has to be changed what ever the dealer or the servive manual is saying... Added also an internal magnet...
Result: Like a dream...
