Frequently Asked Questions
What chassis code does the 280 CE use, and are all variants covered?
The 280 CE rides on the W123 platform – Mercedes-Benz’s acclaimed mid-size chassis used from 1976 through 1985. This manual covers all 280 CE coupes built on that chassis for the full production span, including both European and North American market specifications.
Is the M110 timing chain job covered in detail?
Yes. The M110 dual-row timing chain is a well-known maintenance item on these engines, and the manual includes complete step-by-step procedures for chain and tensioner replacement, correct tensioner preload specs, and reassembly torque values.
Does the manual cover the Bosch K-Jetronic fuel injection system?
Absolutely. Full K-Jetronic coverage includes the fuel distributor, warm-up regulator, cold-start injector, control pressure testing, mixture adjustment, and injector flow testing – everything needed to keep the 280 CE’s injection system running correctly.
