C107's 1981 240D W123

[c107]

As I posted in the Projects Thread, I recently purchased a 1981 240D. I wasn't really looking one, but this super original car fell into my lap and I couldn't say no to it.

I've been enjoying driving it so far as its a good contrast from my other cars.

Here is some information about the car:

That is a mountain of torque.

Huge difference, of course. It amply illustrates the progress in engineering attained over the last thirty five odd. years. Regarding Benz Boy's car - I have reason to believe that the Diesel engine can experience certain problems with the particle (?) filter - I wonder if there is any truth in that. Regards Styria

Styria, some brands have problems with the particulate filter. Generally this is not an issue for Benz. The key to keeping the particulate filter clean is to mix longer trips with short town runs - which I make a point of doing. It is necessary to use low ash oil to MB specifications. The other key is to use an authorised service agent who can run a cleaning programme if necessary when the vehicle is serviced- again something I do.

All very good comments Brian.
Modern diesels need to be maintained professionally for sure.
Brian, does your car run AdBlue?
Cars that run AdBlue have less issues with their DPF’s, but as you stated, good runs are desirable for all modern diesels.

 

[BenzBoy]

The Estate does not run AdBlue but the ML does.

Brian

 

[Patrick_R]

More modern cars are now past using AdBlue with the extreme injection pressures used now.
