CMS 2021 Repair Bench Compendium

Found a part in a barn or the junkyard and you don't know whether it can be repaired or not? Then this is the guide for you!

Continuing on the work of my CMS2018 guide, this guide presents two lists: Parts that can be repaired, and equally as important, parts that cannot be repaired.

Preface

There are many parts available when wandering around barns and the junkyard that can be picked up for a bargain; but can those parts be repaired? Knowing what can or can't be repaired can make the difference in picking up major parts and restoring them at a fraction of the store purchase price. Very useful when restoring that prize vehicle you've been working on.

This guide is primarily made up of two lists: parts that can be repaired and, secondly, parts that cannot be repaired. Knowing what parts are on what list can make the difference on whether you pick up something that has low condition that can be repaired or whether you leave it unless it is in good condition.

As in CMS2018, items have to have at least 15% condition before it can be repaired; so there is no value in picking up any part that is under 15% whether on the repairable list or not.

In order to repair parts you need to have unlocked the Renovator ability and have purchased the work bench once you have expanded the workshop. Each level of the Renovator ability opens up more repairable parts as all parts are levelled. To begin repairing body parts you need to reach level 6 of the Renovator ability and have purchased the body repair station.

Brake Discs and Batteries are not repaired at the Repair Bench but at the Brake Lathe and Battery Charger respectively which is purchased through the Workshop after the workshop has been expanded (Charger can be purchased before the garage expansion). Unlike the Repair Bench, it doesn't cost any money to repair the brakes and recharge the batteries. Batteries can be recharged from 1% condition which effectively means you are not repairing them but recharging them. Brakes do require to be at least 15% condition to use the lathe.

The higher the level of the Renovator ability, the greater the chance to repair the part completely. At level 6 the chance is 60%.

When repairing, the repair sweet spot (green bars) are best to be attempted when they are on the ends. This effectively doubles their size as the cursor runs through them and then returns back. If the placement of bars are not advantageous you can cancel the repair and try again.

These lists are not yet complete and will be updated as I come across the different parts. Exceptions are listed in brackets. If you come across any errors, please mention them in the comments.

If you have found this guide useful, please rate it so that others may come across it and benefit from it. Have fun with the game!

Postface & Log

Currently these lists represent the base game and current DLCs. Mods may have their own idiosyncrasies as mod authors may have used slots for unique modelled parts that may or may not be repairable. These items will generally be in the Body Parts section. I do use a lot of mods so I will add them as I come across them.

When I have tested and checked a greater number of the parts in the game and have filled out my speadsheet a lot more, I will look at adding a link to a Google Sheets file that contains all of the parts in the game and holds further useful information that can be downloaded. This will provide a comprehensive list of each part instead of the grouped information provided in this guide.

A huge thank you to ReXxX who again is assisting this guide by providing information on parts and their repair status. That spreadsheet may get filled out quicker now.

Again, if this guide has been useful to you, please consider rating it with a thumbs up so that others may come across it.

Generally these things cannot be repaired:

[] electronics
[] Soft Material {Rubber furbishing, Belts, etc}
[] Cheap material {Plastic}
[] Fragile Material {Glass}

[darkmethyl13]

Thanks for the list guys. I imagine some time in the future whether it's a modded one or QC missed when it was made but : Fuel/oil/air filter will show up and can be repairable. hmmmmm....THE NPC's that manufactured them must have technology that we do not IRL
🚦🏎️🏁

[Daywalker]

Camshaft (V8 Hemi) is also NOT repairable

[RonV777]

Ignition Wires for an I6 L24 can be repaired.

[RonV777]

I found this interesting, I picked up a Pagani Huayra Tempesta Left Body Window A at 90% in the junkyard, when I started repairing what I brought back it was in the repairable list, so at least some glass is repairable. Does any one have a list of glass that is repairable?

[VHSSerenity]

impressive, thanks for putting in the effort to give the community an extensive guide to part repair, this will be of major help to me

[Mokum]

thank you for the lists

[astrofelix59]

yep, side windows on Pagani can be repaired, safe to say that one's a slip up.

[robert.norgren]

I think it was "Body side window/s" on the Pagani Huayra (sp) that can be repaired.
Only windows that can be repaired.

Good list for which parts can or can't be repaired, but would like to see if performance shop version of the item exists since it is not worth repairing and buying the special version.
