Frequently Asked Questions
Why does the K-Jetronic fuel injection on my C107 run rich or surge at idle?
This is one of the most widely reported issues on C107 SLC models. The Bosch K-Jetronic (CIS) system relies on a precision fuel distributor and warm-up regulator that degrade over time. The manual provides step-by-step pressure testing, warm-up regulator adjustment values, and fuel distributor overhaul procedures to restore correct mixture control on all V8 and inline-six variants.
Is the C107 SLC the same as the R107 SL – does this manual cover both?
The C107 SLC and R107 SL share the same W107 platform, suspension geometry, and powertrains, but differ in body structure – the SLC is the 2+2 fixed-roof coupe while the R107 is an open roadster. This manual is specific to the C107 SLC chassis. R107 SL owners should reference the dedicated R107 manual for body and roof-system procedures unique to that variant.
Does the manual cover the M117 5.0L V8 found in the 450 SLC 5.0?
Yes. The 450 SLC 5.0 – homologated for rally competition – used a bored-out M117 displacing 4,973 cc with aluminum body panels. Full engine rebuild specifications, torque values, timing procedures, and fuel injection details for this high-performance variant are included alongside the standard M117 4.5L coverage.
