I'm thinking of getting a '58 SL 2.0 diesel estate. It felt great on the test drive. Loved the SL seats and the driving position.

Is there anything else I should know or look out for?

Heard some bad opinions about the 2.0 diesel, but is it just performance related or are they problematic?

I would bet most complaints are young owners that thought they had an easy upgrade path to more engine power. If you like the way it drives and feels then I would really not even put much faith in most online complaints. One of the biggest problems with the internet is that there are a lot of people commenting, reviewing and complaining about cars when they should keep their uninformed opinions to themselves.

Things to look out for are generally related to the DPF.

Mine has been removed and the ECU modified and I would not recommend anyone go down that path unless they really know what they're doing and I can't emphasise that enough.

If your driving style is sympathetic to cars fitted with a DPF then you are fine (i.e. you're doing regular long distance highway miles) then all good.

What kills these early models with DPF's is when there are too many short trips that don't allow the DPF to get hot enough to burn off the soot or when people stop the car during a regen cycle and then it restarts.

The regen cycle process dumps excess fuel into the engine which tends to get past the rings into the oil pan...and so too many regens or attempted regens tends to result in oil dilution which then leads to bearing failures if the oil is not changed out.

Otherwise the car is great; The engine has been around for a while and is strong as is the transmission and clutch. Its really a solid decent car and well looked after examples can run to really high mileages without too much issue.

I purchased mine with 140000klms on clock , it has done 160000klms now and was going well until the dpf light started flashing then check engine light came on with a p242f high ash content , i removed dpf and spent a considerable amount of time high pressure washing it . Code 242f remained and i couldnt do a forced regen , took it to a fuel injection specialist and he seems to think its a differential pressure sensor which is mounted on fire wall and where two pipes from dpf go, he suggested changing both . Mazda want 1300 just for one of them , ive have a second hand one on the way and am hoping it rectifies the issue . Apart from that been a great little car

I'm the only active member here who has a diesel so I'm particularly interested. Please update us on the progress.

Sure will do , the part is easy to replace as its bolted to the firewall. The DPF is actually pretty easy to remove , 6 rubber donuts that hold exhaust in , 2 rubber lines that go up to differential pressure sensor and two 14mm nuts that bolt up to turbo manifold , once cars all jacked up was about a 20min job . A remap is around 1400 here in Australia , havent decided if i will do it yet , obviously have to rectify this issue first although im getting conflicting advice that i dont need to rectify the differential pressure issue first but others are saying its a must before any ecu flash . I had a look where ecu is , on passenger floor but instead of 10mm bolts they have sheer bolts , im assuming for occupant protection in the event of an accident

I remember back on 2017 when I was looking for a new car, I've read a lot of complaints on Australia about the diesel variant and the common one is the DPF. The culprit, according to the article, is city driving.

Since my regular route is 160 km one way, any city driving I do for the rest of the week is negated by my travel going back home.

I hope you can post pictures and a step-by-step guide.

I dont really know much about the history of mine as far as driving distance went but i do use this for work daily doing about 130kz round trip and the dpf light would trip in 6th gear dead flat road with cruise control on every single time after about 20klms , i would pull over turn car off straight back on and away i went . I just put it in 5th occasionally now and that fixed it . Strange cars that have a mind if their own , that said i like the torque and economy
