Hi Guys,

I have a problem with my GL and I was wondering if someone here has any idea what is causing the issue.

I did a DPF delete on my 07 GL320 CDI.

Everything is fine with the car except when I drive when it rains or snows out. some how something is getting wet and causing my car to go into limp and its really annoying.

The codes Im getting are P2082 and P2084 which is for exhaust gas temp sensor.

I tried changing the sensor and I get the same problem, any suggestions ?

Just wanted to post an update on this incase something like this ever happens to someone in the future.

I remember a year ago I scanned my car with my star computer. it came up with a differential pressure sensor fault. Foolishly I ignored this and thought it must be something else.

Last weekend a changed the sensor out with a new Mercedes part and it looks like it fixed the issue.

I think the brass piece on the sensor was corroded and when water would get on it it would throw the car into limp mode.

Drove the GL the past week and havent had any problems in slush or rain.

Cant wait to get my new set of blizzaks for the GL, things going to be a proper tank this Canadian winter.
