I am purchasing a new car from skoda family, FABIA. When i saw the car, i noticed some yellow paint spots in engine bay over some of the components. When enquired about the same, the sales person responded stating that its an indication of verification check being done for the component. His explanation seems logically valid but i was not convinced to entirety. I tried to search about it online but could not find any useful or relevant news on the same. I thought its best to ask our gurus and hence posting this thread.

Thanks in advance!

It seems possible. Though i've never seen paint being used.

Did it looks systematic?

Got any pictures?

Its normal. Yellow paint spots are placed at various points for scanning of engine while assembling by computer to verify that all components are present in their place and nothing is missing.

yes, its very common, you will find it mostly on bolts etc, its an indicator that inspection is done on the components by QC.

Nothing to worry, its usual for certain components. but it will be helpful if you could post pictures, as per your statement and the reply of sales person, i find nothing problematic, you can be rest assured.

+1 yes QC marks can be paint, chalk and stickers. Few snaps can really help confirm the same

+1. I have seen it on MS cars too. Guess it of the quality audit.

Cheers!

Trust him, sometimes these guys talk sense.

These are marked through various stages during the assembly. Colors can be red, blue, green, black etc. Usually colors are not significant, some OEM's keep specified colors for particular set of fasteners, it depends. Hope this helps:-

PS- These are not from engine bay although most things are similar, you can post pics if you still have any doubts.

If they are of uniformed shape like dots, then they most certainly are symbolic of QC being done.

The tyre rims of new cars also have blue/green dots on them. Some points in the engine bay have either paint dots or stickers to denote that a QC has been carried out.

If I recall correctly, Hyundai cars have stickers pasted on the windshield after QC.

Like others said, they might be of QC. Incase you are not convinced, I would suggest you to have a look at another Fabia from the same lot as yours to see if that also has similar paint spots.

By the way congrats on your new purchase.

That is used for a different purpose of aligning the tubeless tyre with rims. If you change that alignment, you will never get the correct wheel balancing and at high speeds will experience wobbling.

I have seen such coding in Honda's too. Not one, but all the cars we checked during the purchase of a Jazz recently. In this specific case, I noticed paint applied on nuts on the doors too.

I always thought this was a way of tamper-proofing. A quick, easy way to make sure that if the specific part is removed, then the A.S.S (or any one else ) will know. Can help in many situations, but definitely to know if there was a parts swap.

So, if the paint on such nuts / parts is consistent, then nothing to worry about.

Yes it is a company marking to make sure the parts don't get replaced before reaching the customer. Also some marks are for aligning certain bolts and pulleys too. It is also cheked by SA's for warranty (I was told).
