Hello all - I was wondering whether there are any members familiar with the M113 5.4L?
I am having two issues:
1) Air conditioning is making a groaning noise when switched on - AC compressor was replaced 3 months ago (DENSO part) and has been quite since but for the last week it is very noisy. AC blows ice cold and is fine for the 45c Dubai heat. However, it is very noisy and annoying. Three people have had a look - one says the compressor needs changing, other says the AC pipe needs replacing the last said the AC pipe needs cleaning out...
2) Misfire on idle. I wasn't happy with the Bosch plugs so I had MB original plugs fitted. Now the car is suffering from a misfire - any ideas? All plugs removed and re-seated back in. No codes on STAR. Perhaps the ignition cables need changing / could have been damaged during removal/refitting? Idle was fine before changing the plugs.
Appreciate help in restoring faith in my E55 AMG as I am losing hope recently and thinking of trading it in for something newer.
Mileage is 65,000 and it's a 2001.
Cheers
Bill
