No battery in the boot ? Drivers side under the carpets....

One battery in the boot and 1 in the engine compartment

Still getting this code, upstream turbo temp sensor and this sensor , are these both?

Changed electrical battery in the both, now no fault of under voltage. But still getting the above fault

Sorry, changed battery in the engine compartment, not boot.

Electrical battery is showing Good condition, as its 14 years old, should i change it or not?

My personal opinion is that if you have battery problems, you would have elctrical gremlins around the car. Now your problems are only couple of sensor related, so I would go there and like said check their voltage feed, check their wirings to ecu, and interpret their live data in stationary and difference between couple of working points.

Does anyone know, how much the height of the idle car suspension? Should it show all 4 front and rear or 2 front and 1 rear?

 

[isohail72]

I am still getting fault, Upstream turbo temp above the limit, or too high. B16/19 OR B19/11

Update. I have checked the connector of the upstream turbo temp sensor and guess what I have found out? NICK WEBSTER INDEPENDENT MERCEDES SPECIALIST, didn't clip the connector correctly, one of the two pins were bent, that's why I was getting tempermental engine light and same fault, I have to spend 2 hours and fixed it and when rang them they said it was from before, not us, I replied if it was before you should have install new sensor, why didn't you checked and they have no answer. NICK WEBSTER is totally unprofessional, doesn't know what they are doing, DONT GO THERE!!!!
