Display errors on start up with my M4 2015

[Dalbelice]

To give a little background, I had a Racechip Black GTS, catless pipes, spark plugs and cold air intake installed on my car back in 2021. A week or so after, I started getting Drive train malfunction error randomly. Now, for the last few months I've been getting tons of errors popping up on my display whenever I start the car up and have to clear them all.

I'm attaching pictures here but they are:

Frontal collision warning system
Inactive

Rear axle differential lock reduced

Pedestrian warning
Malfunction

Chassis stabilization

Any idea where I would even begin to figure out what's going on with this?

You need to scan the car for the error. Maybe its a wheel speed sensor gone bad...

Should I just buy that bimmerlink (I think that's what the name was) scanner to do it with?

If you cant find someone local who can scan it for you, i would recommend bimmerlink.

Bimmercode allows you to code the car's features. Bimmerlink allows you to read CELs.

I had this issue and mine was a rear wheel sensor.

You are correct, i typed the wrong app. I edited my post.

Yeah wheel sensor, scan the codes and it will tell you which wheel, the sensor is cheap on eBay, don’t need oem, 10 mins to replace diy

So I finally got the adaptor and ran the bimmerlink app, this is everything I was able to capture...

When I look up error 1801 and error 1800 they both show wheel sensor front and wheel sensor rear on the fault code look up. But the 1BD702 says wheel sensor front?

And here's an export PDF of the "error memory" list

Edit: I just read your first thread. Whoever your shop is taking complete advantage of you. Their "recommendations" list is a joke and the fact that they pushed you to get a racechip says it all. They're amateurs who have ZERO CLUE about this car. 1k to diagnosis issues after they installed it lmao. Insane.

Can you name the shop so other members don't fall for their scams?

1) Ask for a complete refund on the racechip. Flash back to stock and remove. Buy BM3 and use their OTS tunes or get a custom tune.
2) Buy NGK plugs from FCPEuro, gap them to .022. They are free replacements for life. Also an incredibly easy job, takes 2 hours max.
3) given their lack of knowledge I wouldn't be surprised if they forgot to connect something back in. I'd do a thorough search for anything weird.

1k for spark plugs and dp install wow...
