Hey Brother P! In just over two years, I must say not badly at all. I bought the car second hand in 2013 and the rear SAM unit needed replacing, none of the rear lights were working. R 10 000.00 later, but it was paid for by the selling dealer. Since then, there was a thrumming vibration that started about six months after I took ownership and I was petrified that it was the diff. It led to "Google doctoring" and I was horrified at the consequence of such a catastrophe. Thankfully, after sending the car in for new tyres, it turned out that one of the rims was buckled (my fault) so I had all four straightened, cleaned up and the vibration's disappeared.Let me know how yours is treating you. Just had to do some work on my AC compressor. It was causing my engine to stall or alternatively the multiv belt to snap.
The car is currently slightly out of commission at the moment with the secondary air injection pump having given up the ghost and fright the related circuit board in the front SAM unit. The pump issue is seemingly common and there's a thread on here about diagnosis and (if you're brave enough) DIY repair. Anyhow, both of those need to be replaced. I've been told that I can still drive the car but I'd rather not tempt fate. I'm awaiting delivery of the parts and hope to have him back in fine fettle by the end of next week.
Oh and I changed the poly-belt about 20 000km ago, it had developed a squeak but wasn't too badly worn. I don't like odd noises so I had it seen to. Normal wear and tear that though.
Other than those two issues, one self-imposed, I have absolutely no cause for complaint. I love my Blue Monster and have no intention of selling! This one's a keeper and I'm hoping to add an AMG as a stablemate in the next few years.
How long have you had yours for? Any other issues other than the A/C?
I bought mine 2nd hand in 2013 and this is the only issue I have had with it.
The issue was there from the start but it didnt show itself as something serious until the engine stalling drama started to happen.
This combined with a Bosch workshop who knows nothing about repairng cars except to plug them into a diagnostic machine cost me 5 months, 3 poly-belts and a radiator.
Other than this I replaced shocks and tyres. Bought it at 144000km currently at 200000km.
