I own a 7 months Superb 1.8 TSi / 22000 km and when I refil the washer tank I noticed that the upper shocks mont (L & R) are heavily corroded. When contacted the Skoda manufacturer service support in Czech Republic they denied any responsibility but offered to brush the rust and put some grease on it. In the showroom all brand new Skoda Superb have rusted shocks. Moreover one friend from Brussels with same Skoda Superb II, 2 months older than mine same mileage have even more corrosion on the shocks thread and nut. How do you suggest to solve this issue. Should I replace the shocks?

The rust covers the bolt thread and the imbus hex hole.

Can you post a picture of the problem? A (good) picture says much more than a thousand words.

Your'e right, now I attached links to the pictures.

Right shock

How do you suggest to solve this issue. Should I replace the shocks?

Rub the rust down with a wire wheel in a drill then apply a coat of paint to the threads, it's simply cosmetic and certainly does not require replacing - the replacements will rust again as well if the metal has not been plated with a protective coating.

Looks like its nothing to worry about, this happens to un-treated steel, "still" it should be painted or have a plastic cover over it Skoda

No worse than what happens to a brake disc if left unused for a while. Its simply because its bare steel with no protection. Grease or paint will stop it from reoccurring.

looked at mine at the weekend and it is only the left shock top mount corroded and it sist directly under the plastic grill at the base of the windscreen, so the top moint gets a liberal covering of salty water from the screenwash runoff. The other is shielded more and doesn't get anything on it.

Apply Dinitrol rustproofing wax (thin brown wax) with a small paint brush - then forget about it.

It's not structural and will do no harm and it's caused by the usual VAG unplated or poorly plated fasteners. If you treat it now, changing the front dampers later on will be very much easier.

I believe I'll remove the rust and spray some protective sealant. Not very happy to change them as their response is 71/70% and works fine and smooth. Still wait for the dealer decision. Hard to tell

You can't put a nut on a painted shock stem without damaging the paint, so this is going to be same on all shocks.

As above spray with a rust inhibitor and then spray on something like copper grease.

Dealer solved the problem very simple, shocks were dismounted, cleaned and reinstalled. Front shocks are Sachs and rear Monroe. It was just an issue of aesthetic. I started to have more confidence in Skoda, especially the Superb as the dealer attitude changed. I love the smooth ride, even the roads in my country are not very good.

With this occasion also the left fog projector was replaced due condensation.
