Success! Took it to a local place that clearly know what they’re doing and it’s all sorted now. They said they usually fit both bolts on the camber, but did as I asked them from what Tony suggested and it all fell into place nicely. The car is driving like a dream now. Straight as an arrow. The hand written figures are the after on castor. He forgot to do another castor sweep. Thanks again for the advice, Tony.

Well, they've really starred today. After buying the 2 adjustment bolts and them telling me they'd perform any adjustments I wanted, they're now saying they're "not comfortable" staggering the castor as they'd be liable for any wear of other problems resulting from the adjustments, and that they're not happy only having 2 bolts fitted. They obviously just haven't got a clue what they're doing. They've wasted so much of my time. Not happy.

I'll try and get a picture when they do it.

Sorry, I should have said...I'm sat in my local MB dealership right now ordering two bolts. The garage doing the adjustments are being very good about it, to give them their due.

They're able to measure toe, caster and camber angles. The rear of the vehicle was all fine and straight. That picture, if I'm reading it right, is telling me I need a bit more caster on the left. Is that right?

Well, I'm waiting for them to put the car back on their system and they say they can measure/adjust camber and caster. They've also said they'll refund me if they can't get it right. They're adamant that incorrect toe angles will cause a pull though. Seems they disagree with you. Think I'm going to have to agree to disagree with them on that one. Thanks for all your help Tony.

Thanks. Will try that first if I don't get anywhere tomorrow. If things don't go my way, you may well be hearing from me! Thanks again.

Cheers. Never knew that. I always assumed any pull that requires steering input to counter could be cause by any geo angle being misaligned. Just more ammo to throw at them if they can't adjust camber/castor. Out of interest, can you give a ballpark figure of how much it would be to install the adjustment bolts and adjust as necessary if I was to take a drive down to you?

If they can't perform the necessary adjustments, I'll be asking for my money back as they haven't rectified the issue I went to them with. Think I might be in for a bit of an argument.

Nope. They told me how far out the toe measurements were, but no print out. I'll be asking them to show me all the figures when I go back tomorrow.

Thanks, Tony. I have to physically steer slightly right for the car to drive straight. When I let go of the wheel, it self centres and the car goes quickly left. Looking again at the receipt for the work carried out last week, it was front and rear toe adjustment only for £89 which now seems expensive. I'm not even sure what system they have, so god knows if they can even measure-adjust camber/castor.

Sorry to dredge up an old thread, but I'm in more or less the same predicament as the OP. I'd noticed after buying a 13 plate S212 E class that it pulled left more than I'd consider acceptable on roads with camber I'd describe as normal. Before doing my research, I took it to my local F1 autocentre (I get the feeling you'll be groaning about now) for a 4 wheel alignment, telling them I wanted the pull to the left rectified . They carried out the adjustments as they saw fit, and off I went. The car now seems to pull even worse, so whatever they have done certainly hasn't rectified the problem. Am I right in thinking that to properly rectify this, I'll need to purchase and install adjustable caster/camber bolts to dial in a degree more caster on the left front wheel than the right? I'm a bit annoyed that somewhere that presumably carries out hundreds of alignments weren't aware of the problems that MB owners seem to face and after test driving the car thought that the problem had been fixed, when clearly it hasn't. I've got video evidence of the car diving left badly on a smooth road with minimal camber. If they say they can't rectify it to my requirements then I'll be inclined to ask for my money back and then take it somewhere local with a better reputation, or take a day out to WIM. Thanks Edit to say...I think my car might be better described as having a "steer" to the left, seen as I have to constantly steer right to keep it straight.
