Hi to all.
When I bought the 2013 DS4 5 years ago from the dealer, I was told 6 months later the pads and discs front and back wanted changing.
I complained and got them replaced for free.
A year later, after shuddering when braking, I got the front discs and pads changed again.
6 months or so later, it shuddered again, and the garage changed them under warranty.
6 months or so later, after shuddering again, the garage said a brake caliper had gone. So I also needed the front discs and pads changing.
A few months later, after shuddering, they said the other caliper wanted changing, as did the front discs and pads.
During lockdown, as with most, the car didn't do many miles.
About a month ago.... can you guess.... it started shuddering again.
I took it to another garage and had the front discs and pads changed.
Have a guess...
It's now shuddering again!
I'm no boy racer, but it seems worse when I brake a bit harder at speed.
Surely this can't be right?
When the discs and pads are changed the car is fine for a while.
Anybody have any ideas?
I've not long since paid about £1500 to have all the injectors changed.
It's turning into a money pit!
Many thanks.

No idea what your real issue is with your car but my car is 2015, has done about 45000 miles and when I took the pads out last (a few months ago but not many miles ago due to covid) I guess I have about 6 - or 7 k miles left before I'll think about a change. So with yours its not normal wear and tear. Juddering - sounds like an ABS issue, perhaps a proper (not cheapo) code reader may show an issue with the abs system??? But whatever I would not go back to the garages you have used so far given their track record. Did you ask them to change discs and pads or did they give it as a solution? How worn were your pads (and discs)?I don't suppose they put a dial gauge on to find run out of the disc? - and the mounting surface? Quite a few things I would have expected a proper competant garage to have investigated and reported on.
On another note you say you have had the injectors changed. That leads me to assume you have a 1.6 or 2.0litre Hdi engine. I have run up some pretty large mileages with both these engines and have never had to replace injectors, why did yours need to be replaced?

I done the brakes on mine when I got it, the front are still ok looking 40k miles later.
I had to redo the rear, 6 month apart for each side as the caliper started sticking and had toasted the pads. New caliper, new discs and pads each time and all was find since.

If they had sticky calipers then that could warp the discs, not being used much can seize up the caliper too, always make a point of using my car twice a week minimum if possible, even in lockdown.

Thanks for the replies.
It is a 1.6 Hdi.
Never asked for the discs and pads checking.
Just took it in for juddering when braking and they took it out and gave the above opinions.
I did wonder about the ABS but dismissed it because the brakes are fine for a few months once the discs and pads are changed.

They changed the calipers several disc pad changes ago.
I did use it at least twice a week in lockdown to go to the shops.

Are you sitting comfortably?

The injector problem began when on the motorway on a red hot day.
The engine just sort of nearly died and I managed to crawl onto a slip road.
A Green Flag mechanic came out and put his machine on it, which showed No 3 injector was gone.
(From my first call to being taken off the slip road was 8 hours!. I cancelled the next day and joined RAC.)
I got a mechanic out who changed the injector.
We then went out in it and it stunk of diesel which was dripping on the floor when we parked up.
Also the power was not there.
I could do 70 but it took a while to build up to it.
I took it to a local garage.
The leak turned out to be a seal the mechanic had torn on the top rail.
The local garage didn't have the testing facilities to diagnose the power problem.
I tried to take it to a dealer but the nearest was closed down and the next was a 90 minute drive away.
I took it to another local garage that 'specialised' in diagnostics.
After a week they said it was now ok.
Picked it up after paying for the diagnostic test and it was worse than when I took it in, jumping and cutting out for a split second.
Took it back.
A few days later they said it was the DRM? and they could disconnect that without causing problems.
Picked it up and it was still the same.
Took it back.
Days later they said it looked like it was the injectors.
They could send them away for testing at a cost of £15 per injector.
The result was three of them needed replacing.
The one I'd had done before was ok.
They changed the injectors and, engine wise, the car's been fine ever since.
Grand total £1500.

The end.

Oh dear - what a pain in the neck. 1 Ive not heard of injector failure in a PSA engine in many years 2 You seem to have had 4 injector failures 3 It would appear to me that something has got into your fuel system to cause 4 injector failures (renault 1.5 diesel engine high pressure pumps fail and grind up the metal they have inside which causes injectors to fail and cannot be cleaned out of the sytem requiring replacement of everything including the fuel tank).
And then you seem to have a brake problem that none have experienced before, certainly not me in 60+ years of motoring.
Sorry - I can't suggest a solution but wish you the best of luck with your problems

It could be something weird like the abs or master cylinder sticking ans holding a small amount of pressure on.

Or cheap pads that dont fit very well, I've had that on another car. Hard to say unless you were to check things yourself. Was all the work at the same garage, or different ones
