- Rod Bearings.
- Throttle Position actuator
Enjoy the car. One of the best sounding M3's exhaust wise.thanks guys this

Thanks will keep in mindWhen checking the car look for any erratic idle or hesitation through the revs. This may be a sign the throttle actuators are on the way out. Scan the car for any codes as well.
Hopefully rod bearings and throttle actuators are done on the car. That’s a huge plus. Bearings should be done at around 80k km of mileage at the latest.
Inspect the suspension, if the car has edc they are fairly expensive to replace those dampers if you plan to stick with OEM.
The valve cover gaskets leak from time to time, the idler pulley squeaks. These are not particularly large issues but it could help you get the price down to sort that out.
If it’s dct make sure the shifts feel crisp and healthy.
Good luck with the purchase, truly brilliant cars.
Hi is there any good reliable mechanic shop in Durban or PMB to do the rod bearingThanks will keep in mind
What @///Avi said. Also run your hand over the diff to check for slight leak/weeping - it would likely just need new seals.When checking the car look for any erratic idle or hesitation through the revs. This may be a sign the throttle actuators are on the way out.

Either budget for the engine bearings to be changed or verify the invoice with the workshop that did the change.
Check the engine oil level and if no reading, then it possibly needs a new oil level sensor - not uncommon but pricey for the part and labour to replace.
Actuators can fail any time and won't damage the engine so not a critical preventative maintenance item, but can be a PITA to get home in limp mode of/when one or both fail. When 1 goes just replace them both with units from Rebuild.org - they have a lifetime warranty and are 1/4 the price from BMW. Fit them yourself - I'm a novice and I could do it.
Check the life left in the brake discs. Mine needs discs, pads, sensors, fluid - not a cheap day out.
Otherwise normal used car buying advice applies, check service history, signs of changes to the bodywork. Make sure the front wheel arch liners are all in place and intact. The DCT oil cooler sits at the front right and would be exposed to stones/damage if not protected. Also check the condition of the undertray (which is rubbish and will likely need replacing).
None of the above, apart from questionable service history and questionable bodywork, should make you run away from a car, but rather just to be aware of things that could and/or should be on your radar to budget for.
