2007 vRS Diesel 150k miles, passed MOT today with a few advisories, planning to keep car, can anyone advise whether worth replacing these bits or will they last longer yet?

 

Brake disk worn, pitted or scored both sides front

Sub-frame corroded

Anti-roll bar corroded

Coil spring corroded both sides rear

 

Thanks

Not seeing the car it’s impossible to say

Advisories are just that. MOT tester has seen something that might be a concern but not enough for a failure. 

 

Coil springs can corrode within a few years. It might just be surface corrosion. I've had similar on the wife's car for a number of years. Gave them a good clean with a stiff brush and regularly sprayed them with WD40 or similar. They were an advisory for another 5 years but never failed. However one failed on my car. It's was cheap and easy to fix. 

 

I would do the front brakes as a matter of course as these too are relatively cheap. 

 

I'd doubt the subframe is corroded enough to be much of a concern unless you live on the coast and drive through salty water on a regular basis. 

 

Same with antiroll bar. If it fails get it fixed. Not a biggie but just be aware if your handling deteriorates over time. 

 

After all all it's an old car. Bits underneath are bound to be a bit rusty. 

@Rocketship - MoT "advisories" are exactly that, advisory. I once saw a Fail notice with a bunch of advisories on it, and the associated Pass notice (car had been in testing garage, and 2 Majors corrected in the meantime); the advisories had now vanished. I've also had an advisory in year 1, no work on the item and no advisory on it in year 2.

Ken you're spot on with advisories .... That's just that particular testers feeling at the time of the test ... You could take it straight out and drive around the corner to another MOT place and get no advisories on it or advisories on something totally different that garage one was happy with... 

 

My local garage is family owned and I've used it for repairs and my MOT for almost 35 years now ..... The father doesn't work in the garage these days andit's his two sons who run it with Robert concentrating on the MOT side and Andy the repairs although they'll do both over the holidays even though they my car inside out I can get an advisory of Robert one year which Andy doesn't pick up on at the next MOT ... 

Pretty much all coil springs and anto roll bars will be corroded but it would take centuries for them to corrode enough to affect their function unless they have found a way of making them from the special steel reserved for Skoda brake discs

 

I have some German WW1 barbed wire fence pickets, they are a similar diameter to a coil spring and the bottom is a corkscrew spiral of a very similar size, they have spent 100 years outside and 50+ years screwed into the ground where they were used as cattle fencing, were they a road spring they would still be 100% functional but getting an advisory on the MOT.

 

The floorpan & chassis rails are so well protected from corrosion that ancillary bits like brake backplates show up when they have normal corrosion, only a few years ago everything under a car that was not splashed by oil would be similarly corroded, the advisory list would take several pages.

That's not entirely fair; I got a similar rate of corrosion on discs supplied by an Audi specialist.

I am not known for my fairness, lets say VAG brake discs then!

 

In 1987 the company I worked for gave us contract hire cars as part of the package fuel included, it was the days before these benefits were taxed to death.

 

At renewal time we would all take test drives in what we were interested in withing our budget, I had a test drive in an Audi 90 IIRC, they were giving away local ordonnance survey maps with a test drive and I still have it.

 

Anyway the vehicle sounded like a bag of bones, dreadfull tappet noise and a misfire at high revs, several of the hydraulic lifters were stuck, worse still were the brakes which were scraping, groaning and dragging due to severe rust on the discs and frankly they were borderline effective.

 

It may have been a good vehicle but they really ought to have taken better care of their demonstrators.

 

So they must have had the magic steel formulation even back then, perhaps handed on to them from Lancia!
