Background:
- Recently purchased a used C class coupe. Previously (and still do) have one from new so more or less know how they should drive. This one has larger tyres and is slightly faster, otherwise, the same.
- Had the tracking done as the steering wheel wasn't completely straight, off by a few degrees to the left, not much but enough to bother me.
- Four wheel laser alignment done on Saturday
but they aligned it using the profile of a "Mercedes-Benz : 205 (C Class 2014-) : without 4MATIC : with code 485 (Standard Suspension) Sedan/Estate (W/S)".
- The alignment got everything in the green except for the caster (ever so slightly misses the green section on both the left and right front by the same amount) - this can't be adjusted in the same way. (My thoughts are could this genuinely be out or has the wrong profile been selected or both?)
- However, my car is a coupe and is the 2018-2021 model.
- Still doesn't drive as expected as there now appears to be a slight pull to the left in my opinion (two others have driven it and can't notice it, could it just be in my head?). This is different to the initial issue, as it drove relatively straight but the steering wheel was not.
- Tyres are relatively new.
Hence my questions are:
1) Is the hunter machine profile selection wrong or is it likely that it is a generic profile that is used for this car and it should still be ok?
2) This one is potentially obvious but I can see both tyres on the left are 5kpa (0.7 psi) lower than those on the right, could correcting this resolve the issue? I thought the garage should have done that before carrying out the alignment...?
3) More or less unanswerable: could it just be in my head? Two friends have driven it and don't think it's pulling (one of them is a self proclaimed petrol head)
4) Could it be that the alignment has been done correctly and it is the result of the caster being out?
The simple answer to a lot of the above is take it back and have them redo it but it's at least a 50 minute drive away. I did call them up once I noticed the profile discrepancy and the guy on the phone said it might have been human error and to bring it back but I am curious to get the thoughts of the all knowing OcUK Motors section before going back there.
