SL currently in PCS for removal of secondary cats and resonators as well as fitting of Renntech lowering module. ABC light had been coming on so Olly said he would check it out. Just got a call to say rear ABC strut needs replacing. MB now do re-furbished ones which are £400 cheaper than new ones so have gone for this option. Unfortunately needs to come from Germany by road so likely to be 3 - 5 days. Good news is exhaust has been done and according to Olly sounds fantastic. Shame I cant hear it for at least a week!! Still I know car is in good hands and will just have to wait. Love the SL55 and having had one before know the pitfalls of having ABC suspension!!
