Removing Intake Manifold, what should I replace while it's out?

New to the forum and a total BMW noob

I recently bought a 2002 e46 M3 and I'm about to remove the Intake Manifold to replace both Throttle Position Sensors. I'm replacing these because the car has dropped into "LIMP" mode twice now and reading through the threads hear, most people say to start by replacing both TPS sensors. While the Intake manifold is out and while I'm replacing the sensor that sits under the manifold, what else should I replace while it's out? I need to do the power steering, so that too will be done, but if you can recommend replacing anything else, such as vacuum hoses, I would greatly appreciate it. I'm trying to not have to remove the intake manifold too many times.


Thanks for your time.

Wes

You would do best by reading codes first - before buying and replacing things.

Thanks for the quick reply. I unfortunately do not have a scanner (if you could recommend one, I would appreciate it) and the BMW shop I took her to came back with no codes. Like I mentioned, after I shut off the car and turn it back on, the car is fine, so I assume the codes are being wiped?

Thanks again for the reply.

There are a lot of choices when it comes to scan tools for these cars. The forum favorite is probably OBDFushion along with a compatible this one:
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

That will cover your basic codes, from there you can get into more specific tools like BMW Scanner, DIS, INPA and etc.

Depending whether you need to, there are a lot of things for while you are in there.

Air filters, clean icv and tb, you could get into cooling with fan clutch/thermostat/orings, all power steering hoses, accessory belts, engine mounts, starter, heater core and hoses...next thing you know you are replacing the clutch, rebuilding vanos, replacing rod bearings and re-bushing the rear end. That's how it went with me .

So careful about "while you are in there".

If your definitely taking off the intake, I would replace the plastic drain hose. That is going to break. Also replace all the icv hoses while your there & clean it. Before you do anything I would buy a scanner. Is your car smg?

Just be careful that Jason is not working on an S54, common problem areas are somewhat different, we have no disa, cooling system is different, fluids are different, part numbers are different, ccv, etc

Bro my car is having the same issues! Please let me know when you swap out both TPS and if the problems go away. Thanks!
