I'm looking to replace the front suspension and looking online for the replacement, I can see that there are various options where there are some painted dots on the coils. Mine are yellow and red. Many of them have 3 yellow and one red or blue or other combinations. All with the same manufacturer part number. Does that matter? What do those dots represent?

The paint dots are VW group's way of identifying unique spring part numbers.

Same springs on the front of our Roomy, genuine part number is 6Q0411105AG.

Don't fall into the common trap of thinking the letters at the end don't matter much. In this and many other cases, the letters are the only differences in the part numbers amongst all the different variants of spring.

Your shock absorber part number is just about visible on the sticker, 6Q0413031BJ.

Again, the letters make all the difference among the variants.

Thanks @Carlston the LLLParts catalogue very useful. RB

I'm detecting a frequent knock over the smallest imperfections in the road. I got to mimic it in the garage and I can hear it from around the strut area around the top. I don't want to buy OEM, the car is not goin to be around for more than a year or two max. Do i need to buy all of the assembly such as the thrust bearing, suspension strut storage, rubber stop or can I get away with just the struts and move the rest over? I have an mx5 which had similar knock and it was the struts themselves rather than the rubber components. Recently I have replaced the ball joints, ctrl arm bushings, tie rod ends, drop links.

If just replacing the actual bare struts solves your problem, then that was the right thing to do - but if it doesn't, what next - starting with the cheapest to replace part and keep going until you have solved this?

There is a sort of smart way to avoid re-working this area, and in my world where I don't want or need to revisit this area, I always replace the top mounting and bearing, the bump stop might not need replacing, but you will only know that after you have taken the car off the road, if you can live with repeating all this work a few times, then replacing just first the strut should work okay for you.

can someone please help me again how to choose the right parts? 😅 I have been told before but I forgot how to read this and I can't find my own post.

my roomster is a 2007.

Forgive my ignorance, but are they supposed to go down this easily? I've never seen this before.

So an update. I'm ashamed to say that the issue was a droplink 😅 despite me prying it to see if it was intact, and the fact that it was less than a year old. After replacing the struts it was still making the same noise. I replaced the droplinks and it was back to normal. Better than normal actually, the suspension is so much better that what it used to be. I paid about £150 in parts. At 140k it was due. She lives on.
