Hi everyone, I need some help.

I purchased BMW 120i sports (2012 year) from a dealer in Auckland in September 2019. Since last few weeks I have been getting Flat Tyre Monitor (RPA) Failure and ABS (Drive stabilisation and Drive moderately) notification. After doing some online research regarding the tyre sizes I found out the tyres that were fitted in my car were 225/55/R17 and these measurements were not listed in the recommended tyre size list by BMW (found this list on the car body close to driver seat). Then took the car to the dealer he said they are wrong size tyres. He replaced the tyres to 225/45/R17. Since I purchased I have only driven roughly 7000 km. He said after changing the tyres to the right sizes the error will go away but it didn't. The failure notifications still shows up. The dealer advised I will have to pay for the fixing the failure. I am not sure if the failure is due to the car been driven with wrong size tyres or the sensors have failed overtime. He also mentioned the ABS and FTA sensors are separate which I don't agree with him. Any help would be appreciated. Thanks in advance.  Notification images attached. 

Auckland city bmw quoted it. Would they just replace the relay? 

Diagnosis: $341 incl. GST, they advised the fuel pump needs replacing. I drove my car for few Kms, stopped for a coffee in New Market and then tried starting it won't start. 

Below are the parts they said need to replace the fuel pump:

Carry out replace faulty fuel pump
Fuel pump intank xS:
O-ring xB
O-ring xB
Relay, sky blue xS

Does this all make sense? They have quoted me $2,131.27 including gst

Hi, can someone please help me how much will it cost to replace 120i 2012 sports model fuel pump and relay? I am based in Auckland city.
