Only real way is to do a visual check of the items on the advisory list . One mot tester’s pass or fail can be another’s advise .
|
|
What is the advisory? Tyres, brakes etc easy to check. Rust, suspension components far more subjective.
|
|
As above. Advisories are both random and subjective.
The Berlingo was done yesterday and came back with advisories about the front tyres. Both are worn at the extreme outer edge. he rest is OK but a couple of mm above the wear indicators. They were already on my radar and will be seen to in the next 2-3 months. Berlingos tend to wear the outer edges of the tread both front and rear it's just how they are.
I've had Advisories in the past for things totally outwith the owner/keeper's control; engine bay obstructed by acoustic cover multiple times on Berlingo #1 and the phrase 'wet test' on another occasion. The garagiste at the French car specialists who did them says these are cut past items and tell us little more than that oil leaks might be hidden or more difficult to see.
The Xantia's (mildly) corroded rear hydraulic pipes just popped up every year; monitored by me.
Buying a car with advisories on prior year MoTs and not repeated I'd have a good look and if necessary use them to negotiate.

Corroded front brake discs that are no longer mentioned. So is it safe to assume they’ve been replaced?
|
|
No . All cars have some degree of corrosion on the brake discs . It’s actually very difficult to fail an mot on brake disc corrosion. They have to be in an almost dangerous condition for that . Delaminating metal and thin material would fail . Excessive corrosion does not always affect efficiency on the brake roller test .

Disappointingly, but as so often here, age and mileage are not given.
A serviced disc (occasional rust removal with a screwdriver and carborundum wheel) should last around 100,000 miles with normal driving. It's over three years since I replaced the original front pads on my Audi A8, so at nearly 18yrs old but a mere 75,000 miles I thought it was high time for another wheels-off clean-up. After cleaning and 'Hammerite-ing' the brake pipes, I got a surprising amount of rust out of the ventilation channels of the original front discs with an old screwdriver. Some were so occluded that I could not initially push through my length of old clothes hanger wire (don't want to risk overheating discs boiling the brake fluid, do we ;-). Curiously, the rear discs, also original, were much less rusty. But the original rear pads need replacing as the inner ones are now no more than 2mm thick. I'll get my indy to do it at the next MoT (as I'm getting lazy in my dotage, but mainly because I don't want to risk b*****ing up the EPB:-(
While keen on topping up the windscreen washer and cleaning the car, I doubt if any garage includes the above important brake system safety care in a so-called 'service'!

Seriously, with modern pads which are relatively hard?
I'm a driver who, using observation/anticipation and engine braking, minimises anything other than light use of brakes.
Front pads do maybe 25k and discs are sufficiently worn to need replacing with every second set of pads.
I've a contest with the local Skoda dealer who keep flagging the Fabia's lipping on the front discs. Next time it's in, service/MoT in late September, I'm going to insist on them telling me the actual thickness and where it is vis a vis the minimum.
I know they'll need replacing when the pads are done but the current set have significant thickness left before they're worn down until the wear line is gone.

Car brakes vary considerably - my 8-year od VW Touareg is at 60,000 miles on it's original disks and pads and I'm expecting to get 80,000 out of them, despite having to stop a 2.3 ton vehicle - the advice from other owners is to replace disks and pads every time, and they ain't cheap!

Did 100k in my Hyundai i10 before needing to replace the discs and it had only had one set of pads in that time as well.

Not true in Edinburgh in the 1980's. I failed for "visible rust" each and every time, though they passed the brake function test each and every time too. Eventually, for the Renault 5, I took the new disks off after the MOT and put the unshiny-but-functional set back on, keeping the shinies in a plastic bag for the next MOT. Think I only did that a couple of times though.

Not necessarily - twice in my 8-year ownership of my present car, it's had to stand unused for several months when the disks became corroded all over and it took considerable miles afterwards to clean them up - looking at the mileage/time between MoT's may give a clue that the vehicle has been standing unused.

Having looked at a few MoT histories, it seems most testers don't refer to the previous test results and start with a clean sheet. Sometimes it seems that one has checked, repeating last year's advisories, which then disappear the following year (which could mean some work has been done) but then reappear some years later. For example Fuel lines covered in grease or other substance.
|

Bear in mind that as far as the tester is concerned it’s just a job. They would be unlikely to check past MOTs if it meant delaying their morning cuppa. I am not being critical, I’d be the same.
There will be exceptions such as my indie who does all the Mots and servicing himself so he might recall a previous advisory but unlikely.

A very few keen drivers that use the same place every year might (just might) bring in last year's cert with the details .... :-)
|
|
Why should or would they check previous MOTs?
They are meant to be making a judgement on the car as presented to them, not marking someone else's work from 12 months ago.

Because it would give them a pointer to see whether any 'advice' had been taken ? (seems pretty clear to me .... )

The car is tested as presented. Whatever happened last year or 2/3/4 years ago is not relevant. When the mot tester enters the car on the dvla system , previous pass , fails or advisories are not shown .

The next MOT Testers advise might be quite different.
I honestly think most advisories are down to the mood of the tester. I've even seen almost brand new tyres get silly advisories whilst barely legal ones randomly don't get a mention.
