Strange behaviour from my C55

[aquanaut]

Hello folks, had my C55 for over a year and yesterday, for the first time, it started playing up. Cold start, in under a mile of driving it cut out 4 times. Started 'kangarooing' at one point and felt like i was driving with brakes on. each time it happened after i had to brake so at low revs. No warning lights. Steering felt heavier than normal as well. Today its been ok but defo feels different than normal. Also felt a 'pulling' from rear axle. Any thoughts?

Possibly crank sensor? Caused cutting out on my C43. Otherwise maybe coil packs causing misfire, MAFs possibly? I'm sure someone more techy will give you some insight.

sounds like craank sensor, know a few people over the last mnth suffered the same

Doesn't the CPS only start playing up when everything is hot. But does sound like the CPS from what you describe.

Hi, thanks for your thoughts, it was indeed a faulty crank sensor and a MAF as well. Goes back in on Wed to get replaced, thankfully a warranty job!
