The SL350 R230 has a retractable roof.

Greetings, I am in need of assistance. I just purchased an SL350 at an auction and I am now experiencing difficulties with the roof mechanism. The boot/trunk fails to open correctly while attempting to open the roof. The pump seems to be under excessive strain. Upon activating the switch, the boot gradually opens by 3 inches, and upon releasing the switch, it abruptly extends by an additional inch. After repeating this action three times, the object gradually expands to a width of around 10 inches. During each trial, the pump begins with a low volume and progressively amplifies, producing a shrill and piercing sound.Thank you for any guidance or suggestions.

What is the current level of oil?

The fluid level is satisfactory and the flaps are securely fastened. Thank you.

It seems that the pump is experiencing a failure.

Thank you for your response. Are you aware of any methods to determine whether a pump is malfunctioning? (Prior to making a purchase)

Would you want to have the trouble codes scanned?

What is your current location? (When in a rural area, avoid stating that I am now located in the living room.)

I am now located in Newcastle upon Tyne, namely in a kitchen.
