Hi first time I’ve done anything like this . On my 2008 x3 sport I’ve got a problem with the censor in the back near side wheel a gent replaced it but when I set off four lights come on the dash one being the abs , and the fan starts up and the light that looks like a horse shoe upside down with a i in it . I had new disc and callipers and pads fit all round in February but it still comes on . I used to turn car off for a minute and start again and it wouldn’t come on but now with only using the car to go a mile and back it’s on most of the time so any help would be great . Another gent says that the back wheels should be slightly bigger than the front is this true cheers thank you

Morning David

Welcome to the Forum

The first thing to do is to get the diagnostic codes read, you need someone with Autologic as a minimum preferably someone with a BMW specific code reader. That will point you at the issue or issues.

First, Tyres Depending what wheels were originally fitted, will dictate what tyres should be fitted. Often BMW fitted a staggered set more for aesthetics as the car is AWD. If a staggered set up was fitted care should be taken when buying tyres preferably all from the same manufacturer in the correct sizes and at the same time. Differences in rolling radius front to rear or across axles can cause serious damage to the AWD system. If the set up was square (same size front and rear) it will be a little more forgiving but still better to change tyres in pairs on an axle as a minimum if possible.

If you cant do the works yourself check Google for a BMW specialist in your area (there is a register of BMW specialist garages) as the work you have had done seems sketchy. A specialist would be able to read the codes, determine what and where the issue is. Other wise you will be throwing money at it.

Good Luck

Dave
