2003 Cab Alignment / hesitation issue

[jsmirand]

My 2003 Cab top was working perfectly until about a week ago. It began hesitating. So I followed the excellent procedure on this forum on adding hydraulic fluid, used Porsche fluid, filled the reservoir to full. The top hydraulic fluid reservoir was towards the min mark, and I took it to near the max mark.

Unfortunately that didn't really resolve the erratic top behavior.

The top seems to have some more force behind it after adding hydraulic fluid, but the timing seems off. The engine lid opens, the top motor sounds, but the top doesn't move. A second later, the top motor starts again and the top rises but as it meets the front the top latch bumps into the car more so then it ever did before.

Before having a mechanic or dealer look at it, thought to ask if there are any other DIY thoughts that I may want to try.

thanks,

John

Find someone with a PIWIS tool, enter a calibration and read the codes, the best way to start with IMHO.
