BMW 4 Series judder issue

I've recently had my car in for a service and since I got it back it's constantly screeching when I reverse and when driving, it starts to judder when I put the brakes on.
I've had new brake pads and discs fitted and the judder isn't as bad but still noticeable and driving me insane!!
Has anyone else had this problem that could help?
It's a 420D msport xdrive 2015

Take it back and get them to sort it, it can't be diagnosed and fixed on a forum.

This. Could be a number of issues from a stuck caliper to suspension joint wear

Already done that but got no answers.
Well go back again. Too many questions really;

is the judder there when accelerating?
When braking? Do you feel it in the seat? The pedals? The steering wheel? The footwell?
What about when cornering?

See it's an X-drive, have you put any new tyre's on lately?

I had judder on mine, wife had a blow out whilst I was away, she got a new tyres but it broke the transfer box. Hopefully this isn't your issue, as it's very expensive.

Just happens when I'm braking and more noticeable when around 40 to 50 mph. Doesn't happen when accelerating. It's hard to tell if it's from a specific place. I don't really feel it in steering wheel. When coming to a halt the wheels don't feel they grip the road as well as they did. Have 2 new tyres on the back.

You got the right size tyres on?

on the x drive the tyres need to be the same on all four corners
are the the same make / size as the front ?

Screeching in reverse and when driving is not normal. Combined with judder when braking and new discs and pads seem to suggest to me they didn’t fit them properly.

Did you have it serviced at BMW and had the brake work done there? Or was it aftermarket parts by a quick fitter? Do your alloys have spigot rings, and were they replaced or fitted again?

Either way, we can offer ideas but ultimate you got to take it back if it’s not right.

I must admit it’s why I like doing jobs like that myself. And take my time to properly clear everything and ensure after refitting the Caliper carriers that the disc is nicely in the middle.

Also I’ve always found BMW the most sensitive for tyres pressures. Can cause judder but shouldn’t screech. And check that all lug nuts are on and torqued up. A loose nut combined with a non retainer disc can cause this as well.

Thanks. Will have to get it sorted one way or another. Wasn't a BMW garage. Just my normal garage

Are you sure? Is that just for OPs car?

Ive seen a few X Drive BMWs (F30/F31s) with different size tyres front and back.

Edit: or do you mean same diameter? Eg both 19 inch?

As long as the rolling circumference is the same.

To be honest, you're better off taking your BMW to a BMW specialist. They will have all the proper diagnostic tool and have access to the BMW servers.
Time for you to Google your nearest one. Never take it to a generalist garage.

Two Pirellis on the back and 2 Bridgestone on the front.

That is not good. With xdrive (or any other all wheel drive system) you really should keep the same make and model on all four wheels. IIRC it has about 3% tolerance and then can cause all sorts of issues.
